Sprey was a McNamara Whiz Kid, who, according to Robert Coram, entered Yale at fifteen graduating with a double major in French literature and mechanical engineering, then studied statistics and operational research at Cornell before running the statistical consulting shop at Grumman Aviation, before working for McNamara under Alain Enthoven. Sprey became an expert on the history of warfare and tactical aviation. He developed a report on interdiction bombing which asserted it would not deter Soviet forces from invading Western Europe and that the US Air Force should focus on CAS and providing tactical air cover. He was asked to manage the program to develop the A-10, where he leveraged John Boyd's E-M theory and data. Sprey was a vocal critic of the Pentagon's expensive, complex procurement process, and especially the computer model based vulnerability testing of tanks and armored vehicles, since the models weren't validated by field testing. He helped Jim Burton to develop a live-fire test program to provide the validation. who ensured it matched

Initially deadly, infecting and destroying the T-lymphocytes of the immune system, it can now be treated with HAART to become a chronic disease. And with an understanding of HIV's mode of entry into the T-cells, through its binding to CCR5 and CD4 encoded transmembrane proteins, AIDS may be susceptible to treatment with recombinant DNA to alter the CCR5 binding site, or with drugs that bind to the CCR5 cell surface protein preventing binding by the virus.

of the patient base. Pharmacogenomics studies how genes affect a person's response to drugs so as to develop personalized drug treatment plans, tailored to a person's specific phenotype. The process optimizes the treatment process but there are barriers to its deployment: - Large scale clinical trials may test 20,000 individuals, but if a toxic response impacts only 0.1% of them there would only be 20 cases found which is often too few to identify the cause of the response. Instead a process for capturing adverse drug reactions after approval and marketing must be used along with the ability to take a blood sample in these cases.
- Simplified studies on a subset of individuals that have the target allele should be cheaper but are unattractive to pharmaceutical companies which typically want to maximize their target market (Aug 2016).
- F.D.A. has not required genomic testing for most drug developments.
- Health care providers are being slow to use pharmacogenomics. Often third-party payers are unwilling to reimburse the tests.
- Transportation to centralized laboratories for genomic testing causes delays which makes some drug therapy applications impractical. An alternative solution would be to have a patient's EHR contain their genome sequence for immediate genomic implications.

- ABC,
the American Broadcasting Company, was initially a broadcast
radio network founded in 1943 which extended into
television in 1948, following CBS and NBC. The radio
network was sold to Citadel Broadcasting in 2007. In
the 1950s ABC merged with United Paramount Theatres then run
by Leonard Goldenson. Goldenson drove the development
of many successful series which made ABC profitable.
ABC supported the NAM is the National Association of Manufacturers.
Kevin Kruse argues that from 1930 onwards the corporate elite
and the Republican party have developed and relentlessly
executed strategies to undermine Franklin Roosevelt and the New Deal. Their
successful strategy used the credibility of conservative
religious leaders to:
- Demonstrate religious issues
with the New Deal.
- Integrate the corporate
elite and evangelicals.
- Use the power of corporate
advertising and Hollywood to reeducate the American
people to view the US as historically religious and
the New Deal and liberalism as anti-religious
socialism.
- Focus the message through evangelicals including Vereide and Graham.
- Centralize the strategy through President Eisenhower.
- Add religious elements to
mainstream American symbols: money, pledge;
- Push for prayer in
public school
- Push Congress to promote prayer
- Make elections more
about religious positions.
Following our summary of his arguments RSS frames them from the
perspective of complex adaptive system (CAS) theory.

The architects included Henry Morgenthau, Harry Hopkins, and Frances Perkins, who leveraged Al Smith's social welfare reform program plan. The New Deal: - Included liberal legislation: Emergency Banking Relief Act, Banking Act, SSA, Securities Act, Securities Exchange Act, National Housing Act, NIRA, National Labor Relations Act, FLSA, RTAA, Wealth Tax Act;
- Used Presidential executive orders,
- Enhanced the role of federal government in promoting economic growth with programs supporting:
- Reformed trade policy with the RTAA.
- Blocked deflation by limiting economic competition with the NRA.
- Rural standard of living through electrification with the REA and TVA.
- Reduced unemployment with the WPA and CCC.
- Made taxation progressive through the Wealth Tax Act, capturing private wealth and allowing income to flow to the emergent middle class.

Cities Communications was formed as the Hudson Valley Broadcasting Company by Hyman Rosenblum, Leo O'Brien and advertising executive Harry Goldman, licensed to broadcast radio in Albany, New York. In 1954 investors from New York City led by Lowell Thomas purchased control of the company. It was subsequently managed by Tom Murphy and Dan Burke, who began a series of broadcast company mergers, initially with Durham Broadcasting Enterprises, when the company was renamed Capital Cities Television Corporation in 1957. It subsequently also expanded into newspaper publishing by purchasing Fairchild Publications. In 1985 Capital Cities purchased the much larger ABC for $3.5 billion. Warren Buffett, a friend of Capital Cities president Tom Murphy, financed the deal for 25% of the shareholding of the combined company. The merged company was purchased by Disney in 1995. .

They implement abstract designs and are demarcatable by their reduced entropy relative to their components. Rovelli notes entities are a collection of relations and events, but memory and our continuous process of anticipation, organizes the series of quantized interactions we perceive into an illusion of permanent objects flowing from past to future. Abbott identifies two types of entity: - At equilibrium entities,

We build theme parks and rides, hotels and cruise ships. We stage parades and street shows and concerts every day in our fourteen parks across the world. We manufacture fun." But he notes it must provide quarterly earnings reports and meet sharholder expectations and countless other obligations. Additionally Disney, under founder Walt, was a major influencer of the NAM driven Republican strategy to leverage Christianity to undermine FDR and the New Deal. .
- Abhidhamma is a guided theory of meditation includes a variety of practices with the contemplative goal of altering traits to free the subject of suffering. Goleman & Davidson see three distinct levels of practice: beginner, long term meditator, Yogi; with radically different levels of commitment. Beginners typically do a limited-time-investment mindfulness meditation such as MBSR. Long term meditators typically practice vipassana meditation. Yogis practice Tibetan meditations Dzogchen and Mahamudra, which start like vipassana but in a non-dual stance developing a more subtle meta-awareness. Richard Davidson, Cortland Dahl and Antoine Lutz developed a typology of the practices:
- Attentional - train aspects of attention.
- Constructive - cultivate virtuous qualities: loving-kindness;
- Destructive - use self-observation to pierce the nature of experience. These include non-dual approaches where ordinary cognition no longer dominates.
practice is a fifth-century text, which is still the definitive guidebook for Burmese and Thai Theravada meditators explain Goleman and Davidson. It provides the fundamental template for insight meditation, popularly called mindfulness. It details the progression of meditative states to nirvana. It tells of the need to develop a keenly concentrated mind and sharply mindful awareness. The practices for both aspects are described: - Concentration - starts with focus on breath, or any other point of focus, attention on our natural state reveals the monkey mind, As concentration strengthens wandering thoughts subside, and an observable river of thoughts slows to a still lake. Sustained focus brings access concentration where attention stays focused on the target - which may be accompanied by feelings of delight and calm. Jhana first occurs when all distracting thoughts cease and the mind fills with rapture. There are seven more levels of jhana.
- Mindful awareness, looking into the mechanics of consciousness, was a goal of Gautama Buddha, where awareness is left open to whatever arises in the mind, notes what arises and lets it go. A shift to insight meditation occurs where we see the mind as a set of processes. Each shift yields more insights into consciousness. At the highest level strong negative feelings like greed and anger fade away, replaced by traits of equanimity, kindness, compassion and joy.

and methods of transformation: altered traits reflect changes to four neural pathways that Goleman & Davidson identify in Altered Traits. These networks support: stress reactions - induced experimentally with the TSST, compassion and empathy, attention, sense of self; and are altered by different types of meditation. An altered state refers to changes that occur only during meditation. All meditation has the contemplative goal of altered traits leading to being free of suffering by revealing our Bhudda nature. An altered trait indicates that the practice of meditation has tranformed the brain so the induced changes are seen before beginning to meditate. Goleman & Davidson developed a robust behavioral measure for attention: the ability to maintain focus while counting breaths. The test requires pressing a keyboard's down arrow on each outbreath except on the nineth when a different key is pressed and counting restarts at one. The objective metric is the difference between the subjective count and the actual number of breaths taken. ;

- ABL
is a gene on human chromosole 22. In the majority of
cases of CML is chronic myelogenous leukemia. It is a leukemia characterized by the unregulated growth of myeloid cells in the bone marrow. The growth is encouraged by the cellular signalling system (gene change that generates a faulty tyrosine kinase) being locked on. Visual methods allowed Dr. Janet Rowley's team to recognize that most CML includes the Philadelphia chromosome. It encodes the chimeric always on tyrosine kinase protein seen only in CML. Targeted treatments such as Gleevec block the pathway for the tyrosine kinase.
part of ABL is coppied
into a merged chromosome with part of BCR is a gene on chromosome 22 which normally codes the breakpoint cluster region protein which is a GTPase-activating protein for RAC1 and CDC42. In many cases of CML part of the BCR gene gets translated onto an additional Philadelphia chromosome along with part of gene ABL from chromosome 9.
from chromosome 9, in a transformation initially noted by
Dr. Janet Rowley and colleagues and called the Philadelphia chromosome is a chromosome fragment generated by a mutation copying bits of chromosome 9 including part of gene BCR and part of gene ABL from chromosome 22. In the majority of cases of CML Philadelphia chromosome is present and generates an aways on tyrosine kinase signalling protein which causes vast proliferation of white blood cells. Since the protein is aberrant blocking its production pathway with drugs such as Gleevec stop the excessive white blood cell production. .

- The federal
national mortgage association, a GSE.
It was made a publically traded company by the HUD act of 1968 to remove
its debt from the federal budget.
- In 1970 FNMA was authorized to purchase conventional
mortgages. FHLMC was setup
to ensure competition for FNMA in this task.
- In 1981 FNMA issued its first designated MBS.
- In 1992 the Democratic Congress and President Bush
established HCDA which gave FNMA affordable housing goals
set annually by HUD with
Congressional approval.
- In 1999 the Clinton administration put pressure on FNMA
to expand loans to low and moderate income
borrowers. FNMA took on additional subprime
risk.
- In 2000 HUD placed anti-predatory lending rules on the
affordable housing goals, but these constraints were
dropped in 2004. In effect they just pushed mortgage
originators to Wall
Street finance.
- Once mortgage
originators started to use warehouse loans, the GSEs
lost visibility and control of origination.
- The GSEs purchased AAA mortgages from commercial
banks. Many of these classifications were fraudulent
leaving the GSEs with bad debt. In 2008 to maintain
the stability of the global economy
the George W. Bush administration seized the GSEs and
placed them in conservatorship under the FHFA, ensuring
they could not collapse.
- In 2010 FNMA's stock was delisted from the NYSE.

- Collateralized mortgage obligation. The collateralized mortgage obligation was invented by Larry Fink (BlackRock) and team while they were at First Boston in 1983. The key innovation was that the risk in these contracts was more predictable than in an MBS due to the presence of a trust that guaranteed payments to the bond holders. The risk was separated into tranches with different credit ratings and yields. The structure was used by the banking and securities companies to finance the subprime housing boom.

the Health Care and Education Reconciliation is a fast-track Senate procedure defined in title III of the CBIC act. In response to a stagnant economy and President Nixon's spending controls it was hoped this process would help with acting rapidly on the rising budget deficit and increasing entitlement spending. The process is constrained by Senate rules that limit its use to provisions that deal with government tax and spending activities, but not policy:
- Senators can object to a reconciliation bill if they see the rules being broken & ask for the parliamentarian to judge if a provision of a bill fails the rules.
- If the parliamentarian judges the proposal does fail the rules, the bill must be passed by 60 votes to overcome the objections, rather than a simple majority of the Senate or the provision must be stripped from the bill.

to Medicare is a social insurance program that guarantees access to health insurance for Americans aged 65 and over, and younger people with disabilities and end stage renal disease or ALS. Medicare is currently missing a cap on out-of-pocket costs and direct prescription drug coverage. It includes: - Benefits
- Part A: Hospital inpatient insurance. As of Dec 2013 Medicare pays for home care in only limited circumstances, such as when a person needs temporary nursing care after a hospitalization. Part A covers 20 days of inpatient rehabilitation at a SNF after discharge from inpatient care at a hospital.
- Part B: Medical insurance for non-hospital services including: doctor visits, tests, injectable drugs, ambulances, physical therapy;
- Part C: Medicare Advantage
- Part D: indirect prescription drug coverage The MMA prohibits Medicare from directly negotiating drug prices.
- Eligibility
- All persons 65 years of age or older who are legal residents for at least 5 years. If they or a spouse have paid Medicare taxes for 10 years the Medicare part A payments are waived. Medicare is legislated to become the primary health plan.
- Persons under 65 with disabilities who receive SSDI.
- Persons with specific medical conditions:
- Have end stage renal disease or need a kidney transplant.
- They have ALS.
- Some beneficiaries are dual eligible.
- Part A requires the person has been admitted as an inpatient at a hospital. This is constrained by a rule that they stay for three days after admission.
- Sign-up
- Part A has automatic sign-up if the person is drawing social security. Otherwise the person must sign-up for Part A and Part B.
- Should sign-up for Part B during the Initial Enrollment Period, of seven months centered around 65th birthday, online or at a social security office. But if still covered by spouse's insurance or not yet retired then may only join during the 3 month general enrollment period (January to March) each year, with coverage initiated the following July. Incremental yearly 10% penalties apply for not signing up at 65. These penalties apply to all subsequent premiums.

piloting new ways for PCP is a Primary Care Physician. PCPs are viewed by legislators and regulators as central to the effective management of care. When coordinated care had worked the PCP is a key participant. In most successful cases they are central. In certain Medicare ACO models (Pioneer) PCPs are committed to achieve meaningful use requirements. Working against this is the: replacement of diagnostic skills by technological solutions, low FFS leverage of the PCP compared to specialists, demotivation of battling prior authorization for expensive treatments. s to manage
patient care to keep patients away from costly E.D. is emergency department. Pain is the main reason (75%) patients go to an E.D. It has traditionally been part of an acute care hospital but recently is being deployed standalone as a catchment funnel to the owning hospital. The EMTALA legislation requires E.D. treatment to stabilize every person seeking treatment by most hospitals. Unreimbursed care is supported from federal government funds. E. D. profitability has been helped by hospitals contracting with 3rd party companies who are able to improve margins through surprise billing. The standalone E.D. competes with the positioning and brand power of lower cost urgent care clinics. Commercial nature of care requires walk-ins to register to gain access to care. With the focus on treatment of pain, E.D.s are a major distributor of opioids (5% of opioid prescriptions) and a major starting point of addiction in patients but are cutting back (Jun 2016). s.

- Medicare solvency improvements.
- Medicaid is the state-federal program for the poor. Originally part of Lyndon Johnson's 1965 Bill, eligibility and services vary by state. Medicaid currently pays less for care than Medicare, resulting in many care providers refusing to participate in the program. Less than 10 percent of Medicaid recipients, those in long-term care including nursing homes where 64% are dependent on Medicaid, use one-third of all Medicaid spending which is a problem. The ACA's Medicaid expansion program, made state optional by the SCOTUS decision, was initially taken up by fifty percent of states. As of 2016 it covers 70 million Americans at a federal cost of $350 billion a year. In 2017 it pays for 40% of new US births.

But with government interested in reducing the US health care cost curve ACA's HRRP (pay-for-performance), BPCI and CTI and Interact discharge initiative have all increased the focus on unnecessary readmissions. Now the end-to-end process is under scrutiny with hospitals reengineering discharge (RED) and PAC providers using RAI and TCN.

Such hospitals with higher than expected readmissions rates will receive reduced Medicare payments for all Medicare discharges relating to three medical conditions: heart failure, acute myocardial infarction, and pneumonia. The reductions will be driven by an adjustment factor of 1% in 2013, 2% in 2014, and 3% subsequently. The incentives/penalties induce complex adaptive responses (Dec 2018) ) which was

- CMS has developed APMs which include ACOs, and advanced APMs where the ACOs must be risk bearing.
- CMMI accepts providers' proposals to test various payment systems including shared savings and partial capitation.
- Private market ACOs have formed including: Providence Health & Services, Blue Shield California, Anthem Blue Cross, United Health Care, BCBS Minnesota, BCBS Illinois, Humana, CIGNA, Main Health Management Coalition, BCBS Massachusetts, Aetna.

- Include enough PCP is a Primary Care Physician. PCPs are viewed by legislators and regulators as central to the effective management of care. When coordinated care had worked the PCP is a key participant. In most successful cases they are central. In certain Medicare ACO models (Pioneer) PCPs are committed to achieve meaningful use requirements. Working against this is the: replacement of diagnostic skills by technological solutions, low FFS leverage of the PCP compared to specialists, demotivation of battling prior authorization for expensive treatments.

Medicare is a social insurance program that guarantees access to health insurance for Americans aged 65 and over, and younger people with disabilities and end stage renal disease or ALS. Medicare is currently missing a cap on out-of-pocket costs and direct prescription drug coverage. It includes: - Benefits
- Part A: Hospital inpatient insurance. As of Dec 2013 Medicare pays for home care in only limited circumstances, such as when a person needs temporary nursing care after a hospitalization. Part A covers 20 days of inpatient rehabilitation at a SNF after discharge from inpatient care at a hospital.
- Part B: Medical insurance for non-hospital services including: doctor visits, tests, injectable drugs, ambulances, physical therapy;
- Part C: Medicare Advantage
- Part D: indirect prescription drug coverage The MMA prohibits Medicare from directly negotiating drug prices.
- Eligibility
- All persons 65 years of age or older who are legal residents for at least 5 years. If they or a spouse have paid Medicare taxes for 10 years the Medicare part A payments are waived. Medicare is legislated to become the primary health plan.
- Persons under 65 with disabilities who receive SSDI.
- Persons with specific medical conditions:
- Have end stage renal disease or need a kidney transplant.
- They have ALS.
- Some beneficiaries are dual eligible.
- Part A requires the person has been admitted as an inpatient at a hospital. This is constrained by a rule that they stay for three days after admission.
- Sign-up
- Part A has automatic sign-up if the person is drawing social security. Otherwise the person must sign-up for Part A and Part B.
- Should sign-up for Part B during the Initial Enrollment Period, of seven months centered around 65th birthday, online or at a social security office. But if still covered by spouse's insurance or not yet retired then may only join during the 3 month general enrollment period (January to March) each year, with coverage initiated the following July. Incremental yearly 10% penalties apply for not signing up at 65. These penalties apply to all subsequent premiums.
- Premiums
- Part A premium
- Part B insurance premium
- Part C & D premiums are set by the commercial insurer.
FFS is fee-for-service payment. For health care providers the high profits were made in hospitalizations, imaging and surgery. Due to its inducing excessive treatment activity it may be replaced by FFV bundled payment.

- Be accountable for the quality and cost of care
provided to the Medicare FFS patient population.
- Have defined processes to promote: Evidence-based
medicine is evidence based medicine where explicit and judicious use of current best practice evidence is used in making decisions about the care of patients. There are differences in the application to individuals and populations. Still the goal was to replace subjective use of basic and clinical research with:
- Prioritization of clinical trial results to build conclusions.
- Adoption of processes that translated epidemiological methods to physician decision making.
- Widely used but innapropriate procedures were abandoned.
- There is now explicit evaluation of evidence of effectiveness before issuing practice guidelines. A rational for adoption is required.
- HHS appointed USPSTF to develop evidence based recommendations.
, Patient-centeredness, Quality reporting,
Cost management, Coordination
of care aims to transfer information between the patient and each care participant as required and establish accountability by defining who is responsible for each care delivery activity, the extent of that responsibility and when that responsibility will be transferred to other care participants or the patient and family. Successful care coordination requires face-to-face interactions. It also requires aligned incentives (ACO, Bundled payments). AHRQ defines quality measures for care coordination. The situation is usually complex and adaptive due to the interactions of all the providers, settings, the patients' preferences, and the number of physical health problems, treatments, and the patients' social situation. The potentially exponential increase in complexity as the number of these factors present increases leads to patient hot spots requiring explicit proactive coordination of care. It is argued that care coordination must include six specific activities: - Determination and updating of care coordination needs: Needs assessment should identify preferences and goals, current situation and past history. It needs to be updated periodically and after new diagnosis and other changes in health or functional status.
- Creation and updating of proactive plan of care
- Communication
- Facilitation of transitions: typical transition problems are detailed by Project Boost. A challenging issue with transitions is what to do when there is no resource to take over the coordination role in the handoff.
- Connection to community resources: Community resources are any service or program outside the health care system that may support a patient's health and wellness.
- Alignment of resources with population needs: need to see the system-level, assess the needs of populations to identify and address gaps in services.

patient-centeredness criteria including use of patient
and caregiver assessments and individualized care plans outline the patient's current and long-term needs and goals for care, identifies coordination needs, and addresses potential gaps. This is consistant with the biopsychosocial model. It also clarifies how the patient will reach the goals and who is responsible for implementing each part of the plan. HL7's FHIR has defined a CarePlan resource. .
- CMMI is the center for Medicare and Medicaid Innovation. It is a test bed for new ways of financing and delivering care. It allowed Congress to institutionalize innovation sending a signal to providers that they would be participating in CMS driven programs that could become mainstream. It funds evaluations of innovative health care models. Under the ACA if the HHS secretary finds any of its projects would reduce Medicare spending without harming the quality of care the projects may be expanded nationwide. The CBO estimates the CMMI will save $34 billion between 2016 and 2026. CMMI projects include:
- Medicare will make a bundled payment for hip and knee replacement surgery (CJR) and 90 days of follow-up care forcing hospitals to work closely with doctors, nursing homes and home health agencies.
- New ways to pay for prescription drugs, medical devices, cancer care (OCM).

- Subtitle A: Improved access to Medicaid is the state-federal program for the poor. Originally part of Lyndon Johnson's 1965 Bill, eligibility and services vary by state. Medicaid currently pays less for care than Medicare, resulting in many care providers refusing to participate in the program. Less than 10 percent of Medicaid recipients, those in long-term care including nursing homes where 64% are dependent on Medicaid, use one-third of all Medicaid spending which is a problem. The ACA's Medicaid expansion program, made state optional by the SCOTUS decision, was initially taken up by fifty percent of states. As of 2016 it covers 70 million Americans at a federal cost of $350 billion a year. In 2017 it pays for 40% of new US births.

CHIP's funding must be iteratively re-authorized by Congress. CHIP is financed federally, but states must enroll eligible children. In many states one agency administers CHIP and Medicaid. CHIP is leveraged by families that have employer based insurance with costly premiums, so the families only cover the adults.

- Includes the subgenual ACC and the paragenual ACC, and
Brodmann areas 24, 25 is the Subcallosal Cingulate Cortex, an area of the ACC, which Kandel explains, is a region where thought, motor control and drive come together. It is rich in neurons generating serotonin transporters. It is directly involved in a signalling network with: amydala, hypothalamus, hippocampus, insula cortex; that integrates thinking and emotion to plan and respond effectively. Kandel notes whenever area 25 becomes hyperactive, the components of this circuit associated with emotion are disconnected from the thinking brain resulting in a loss of personal identity. , 32 and
33.
- The gyrus of the ACC has two functional components,
which both operate abnormally in mood disorders: depression is a debilitating episodic state of extreme sadness, typically beginning in late teens or early twenties. This is accompanied by a lack of energy and emotion, which is facilitated by genetic predisposition - for example genes coding for relatively low serotonin levels, estrogen sensitive CREB-1 gene which increases women's incidence of depression at puberty; and an accumulation of traumatic events. There is a significant risk of suicide: depression is involved in 50% of the 43,000 suicides in the US, and 15% of people with depression commit suicide. Depression is the primary cause of disability with about 20 million Americans impacted by depression at any time. There is evidence of shifts in the sleep/wake cycle in affected individuals (Dec 2015). The affected person will experience a pathological sense of loss of control, prolonged sadness with feelings of hopelessness, helplessness & worthlessness, irritability, sleep disturbances, loss of appetite, and inability to experience pleasure. Michael Pollan concludes depression is fear of the past. It affects 12% of men and 20% of women. It appears to be associated with androgen deprivation therapy treatment for prostate cancer (Apr 2016). Chronic stress depletes the nucleus accumbens of dopamine, biasing humans towards depression. Depression easily leads to following unhealthy pathways: drinking, overeating; which increase the risk of heart disease. It has been associated with an aging related B12 deficiency (Sep 2016). During depression, stress mediates inhibition of dopamine signalling. Both depression and stress activate the adrenal glands' release of cortisol, which will, over the long term, impact the PFC. There is an association between depression and additional brain regions: Enlarged & more active amygdala, Hippocampal dendrite and spine number reductions & in longer bouts hippocampal volume reductions and memory problems, Dorsal raphe nucleus linked to loneliness, Defective functioning of the hypothalamus undermining appetite and sex drive, Abnormalities of the ACC. Mayberg notes ACC area 25: serotonin transporters are particularly active in depressed people and lower the serotonin in area 25 impacting the emotion circuit it hubs, inducing bodily sensations that patients can't place or consciously do anything about; and right anterior insula: which normally generates emotions from internal feelings instead feel dead inside; are critical in depression. Childhood adversity can increase depression risk by linking recollections of uncontrollable situations to overgeneralizations that life will always be terrible and uncontrollable. Sufferers of mild autism often develop depression. Treatments include: CBT which works well for cases with below average activity of the right anterior insula (mild and moderate depression), UMHS depression management, deep-brain stimulation of the anterior insula to slow firing of area 25. Drug treatments are required for cases with above average activity of the right anterior insula. As of 2010 drug treatments: SSRIs (Prozac), MAO, monoamine reuptake inhibitors; take weeks to facilitate a response & many patients do not respond to the first drug applied, often prolonging the agony. By 2018, Kandel notes, Ketamine is being tested as a short term treatment, as it acts much faster, reversing the effect of cortisol in stimulating glutamate signalling, and because it reverses the atrophy induced by chronic stress. Genomic predictions of which treatment will be effective have not been possible because: Not all clinical depressions are the same, a standard definition of drug response is difficult;, anxiety is manifested in the amygdala mediating inhibition of dopamine rewards. Anxiety disorders are now seen as a related cluster, including PTSD, panic attacks, and phobias. Major anxiety, is typically episodic, correlated with increased activity in the amygdala, results in elevated glucocorticoids and reduces hippocampal dendrite & spine density. Some estrogen receptor variants are associated with anxiety in women. Women are four times more likely to suffer from anxiety. Louann Brizendine concludes this helps prepare mothers, so they are ready to protect their children. Michael Pollan concludes anxiety is fear of the future. Sufferers of mild autism often develop anxiety disorders. Treatments for anxiety differ. 50 to 70% of people with generalized anxiety respond to drugs increasing serotonin concentrations, where there is relief from symptoms: worry, guilt; linked to depression, which are treated with SSRIs (Prozac). Cognitive anxiety (extreme for worries and anxious thoughts) is also helped by yoga. But many fear-related disorders respond better to psychotherapy: psychoanalysis, and intensive CBT. Tara Brach notes that genuine freedom from fear is enabled by taking refuge.
& bipolar also termed manic-depression is an episodic developmental disorder beginning in late adolescence, which can stimulate great creativity during the manic phase and suicide in the depressive phase. Vincent van Gough suffered from depression for much of his adult life, and killed himself at thirty seven. He produced three hundred of his greatest art works, using color to convey mood, while struggling with psychotic depression and mania in the last two years of his life. Only the first manic phase requires a significant positive or negative stressful situation. Type I bipolar includes more manic situations which may include psychosis. Type II does not include psychosis. Some people suffer 'mixed state' where mania and depression occur at the same time. Sleep deprivation activates the amygdala and can induce mania in some people with bipolar disorder. It affects 3 million Americans. The amygdala is more active in people with bipolar disorder. Franz Kallman found identical twins are likely (70% chance) to share the disorder. Swedish researchers studying thousands of families in 2009 showed a strong hereditary link between bipolar disorder and schizophrenia, which was corroborated in 2012. Genetic analysis of 2.3 million different regions of DNA of 9,747 people with bipolar disorder and 14,278 comparable people without, found five regions that appear connected with bipolar disorder. Gene ADCY2, was identified, supports production of an enzyme facilitating neural signalling, and correlates with observed impairment of communication in certain brain regions in bipolar disorder. GWAS implicate ANK3 and CACNA1C SNPs in bipolar disorder. And de Novo mutations increase the risk. Lithium limits the extremes of the mood swings in some patients but has side effects. Anti-psychotic medications are prescribed. . The
- Rostral/ventral part is involved in emotional are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism.
processes and
autonomic functions. It connects to the hippocampus is a part of the medial temporal lobe of the brain involved in the temporary storage or coding of long-term episodic memory. It includes the dentate gyrus. Memory formation in the cells of the hippocampus uses the MAP kinase signalling network which is impacted by sleep deprivation. The hippocampus dependent memory system is directly affected by cholinergic changes throughout the wake-sleep cycle. Increased acetylcholine during REM sleep promotes information attained during wakefulness to be stored in the hippocampus by suppressing previous excitatory connections while facilitating encoding without interference from previously stored information. During slow-wave sleep low levels of acetylcholine cause the release of the suppression and allow for spontaneous recovery of hippocampal neurons resulting in memory consolidation. It was initially associated with memory formation by McGill University's Dr. Brenda Milner, via studies of 'HM' Henry Molaison, whose medial temporal lobes had been surgically destroyed leaving him unable to create new explicit memories. The size of neurons' dendritic trees expands and contracts over a female rat's ovulatory cycle, with the peak in size and cognitive skills at the estrogen high point. Adult neurogenesis occurs in the hippocampus (3% of neurons are replaced each month) where the new neurons integrate into preexisting circuits. It is enhanced by learning, exercise, estrogen, antidepressants, environmental enrichment, and brain injury and inhibited by various stressors explains Sapolsky. Prolonged stress makes the hippocampus atrophy. He notes the new neurons are essential for integrating new information into preexisting schemas -- learning that two things you thought were the same are actually different. Specific cells within the hippocampus and its gateway, the entorhinal cortex, are compromised by Alzheimer's disease. It directly signals area 25. , amygdala contains > 12 distinct areas: Central, Lateral. It receives simple signals from the lower parts of the brain: pain from the PAG; and abstract complex information from the highest areas: Disgust, heart rate, and suffering from the insula cortex, allowing it to orchestrate emotion. It connects strongly to attention focusing networks. It sends signals to almost every other part of the brain, including to the decision making circuitry of the frontal lobes. It has high levels of D(1) dopamine receptors. During extreme fear the amygdala drives the hippocampus into fear learning. It outputs directly to subcortical reflexive motor pathways when speed is required. Its central nucleus projects to the BNST. It signals the locus ceruleus. It directly signals area 25. The amygdala: - Promotes aggression. Stimulating the amygdala promotes rage. It converts anger into aggression and when impaired it impacts the ability to detect angry facial expressions.
- Participates in disgust
- Perceives fear promoting stimuli, focusing our attention on these. In PTSD sufferers the Amygdala overreacts to mildly fearful stimuli and is slow to calm down and the amygdala expands in size over a period of months. Fear is processed by the lateral nucleus which serves as the input from various senses, and the central nucleus which outputs to the brain stem (central grey - freezing, lateral hypothalamus - blood pressure, activates paraventricular hypothalamus => crf -> hormone adjustments).
- Has lots of receptors for and is highly sensitive to glucocorticoids. Stress inhibits the GABA interneurons in the basolateral amygdala (BLA) allowing the excitatory glutamate releasing neurons to excite more.
- Is sensitive to unsettling/uncertain social situations where it promotes anxiety and makes us distracted. It is also interested in uncertain but potentially painful situations. The amygdala contributes to social and emotional decision making where the BLA supports rejecting an unacceptable offer, as allowed in the Ultimatum Game, by injecting implicit mistrust and vigilance, generating an anger driven rejection that is used as punishment. The amygdala is very rapidly excited by subliminal signals from the thalamus of outgroup skin color. The amygdala subsequently tips social emotions against outgroups unless restrained by the frontal lobe or influenced by subliminal priming to prioritize inclusion. The fast path from the thalamus rapidly but inaccurately signals its identified a weapon.
- Sees suffering of others as increasingly salient with loving-kindness meditation practice, Goleman & Davidson explain.
- Promotes male, but not female, sexual motivation when it is an uncertain potential pleasure.
- Responds to the longing for uncertain potential pleasures and fear that the reward will not be worth it if it happens. The amygdala turns off during orgasm.
- Uses but is not directly involved in vision.
, orbital prefrontal
cortex is a rich club hub region of the prefrontal cortex, involved in representing emotion & reward in decision making. It is positioned immediately above the orbits where the eyes sit. The medial part judges the beauty of faces, minds and acts and will conflate them in social emotion evaluations. The orbitofrontal cortex receives projections from the: hippocampus & associated areas of the cingulate, retrosplenial & entorhinal cortices, anterior thalamus, amygdala, midline thalamus, non-isocortical insula, mediodorsal thalamus. , anterior
insula is a rich club hub within the insula cortex. It is anatomically subdivided by sulci into gyri. It is where self-awareness and social experience integrate. Feelings from the internal state of the body are used to generate emotions. It includes a direct projection from the: thalamus's ventral medial nucleus, central nucleus of the amygdala. The anterior insula projects into the amygdala. It includes spindle neurons. , nucleus
accumbens is a region of the basal forebrain (striatum) rostral to the preoptic area and immediately adjacent to the septum. The nucleus accumbens was closely associated with the limbic system, mediates the impact of emotion and plays an important role in reinforcement. If a rodent wins a fight on his home territory, there are long-lasting increases in levels of testosterone receptors enhancing pleasurable effects. When prairie voles first mate, epi-genetic state changes are induced in the accumbens to support pair-bonding. The accumbens projects to brain regions associated with movement. The major pathways of dopaminergic neurons begin in the substantia nigra and the ventral tegmental area. The amygdala projects back to the accumbens. The tegmentostriatal system begins in the ventral tegmental area and projects to the nucleus accumbens. The nucleus accumbens includes high levels of D1, D2 and D3 dopamine receptors located on the spine & shafts of dendrites of excitatory cells reduce the transfer of excitation from the dendrites to the cell bodies, so only especially strong excitatory inputs get through to the cell body to elicit excitation. It also has D4 dopamine receptors which are highly variable. The accumbens responds differently to rewards depending on maturity: In juveniles all reward levels result in the same response activity level, During adolescence the accumbens responds to small rewards negatively, and large rewards hugely, In adults the rewards result in measured scaled positive responses. Chronic stress depletes dopamine from the nucleus accumbens biasing humans towards depression. . It is overactive during regular
or bipolar depression.
- Caudal part is involved in cognition and the control
of behavior. It connects with the dorsal PFC is prefrontal cortex which is:
- The front part of the frontal
lobe of the cerebral
cortex. It evolved
most recently. During adolescence
when the PFC is still deploying, older brain agents provide equivalent strategies: ventral striatum.
The PFC has been implicated in planning, working memory: dorsolateral;
decision making: Orbitofrontal cortex;
and social behavior. It regulates feelings. Different PFC
circuits track internal reward
driven strategies and externally signalled advice. The
PFC chooses between conflicting options, letting go or
restraint, especially between cognition
and emotions. It imposes
an overarching strategy for managing working memory.
It is essential for thinking about multiple items with
different labels. It includes neurons that are
interested in particular sub-categories: Dog, Cat.
Once it has made a decision it signals
the rest of the frontal lobe just behind it. Glucocorticoids decrease
excitability of the PFC.
, secondary motor cortex is the posterior precentral gyrus region of the frontal lobe of the cerebral cortex involved with planning, control and execution of voluntary movements. , and posterior cingulate
cortex (PCC) is a brain region where invariant-location cells dwell. It is closely connected to the parahippocampal gyrus. It activates during self-focused thought. University of Massachusetts Medical School Center for Mindfulness research director, Judson Brewer, sees the PCC participation in: distraction, wandering attention, thinking about ourselves, liking an immoral choice, feeling guilty, and craving. Its activation was reduced by mindfulness meditation explain Goleman & Davidson.
- Is a central focus of empathy is the capability to relate to another person from their perspective. It is implemented by spindle neurons. Empathy towards others is controlled by the right-hemisphere supramarginal gyrus. Empathy is context dependently mediated by estrogen. It develops over time: Piaget's preoperational stage includes rudimentary empathy, Theory of mind supports the development; initially feeling someone's pain as one integrated being, then for them and eventually as them. In adults, when someone else is hurt the anterior cingulate cortex, amygdala & insula activates projecting [scapegoating] to the vmPFC. If the pain is physical the PAG activates and motor neurons for the area where the other person was injured. The intertwining of the ACC amygdala & insula in adults results in attribution of fault even when there is none which can make it hard to step in and actually help. But in seven-year-olds the activation is concrete: PAG and sensory & motor cortexes with minimal coupling to the rudimentary vmPFC. In older children the vmPFC is coupled to limbic structures. Ten to twelve year olds abstract empathy to classes of people. Brizendine asserts young girls develop empathy earlier than boys, because their evolved greater neuronal investment in communication and emotion networks. Year old girls are much more responsive to the distress of other people than boys are. At 18 months girls are experiencing infantile puberty. By adolescence the vmPFC is coupled to theory of mind regions and intentional harm induces disgust via the amygdala. Sapolsky explains adolescent boys are utilitarian and tend to accept inequality more than girls do. But both sexes accept inequality as the way it is. Sociopaths do not develop empathy.
supporting people relating
to other's pain. This is dependent on oxytocin is a peptide hormone which makes humans more prosocial to and socially competent in their in-group and more antisocial to everyone else. The effects are contingent; changing during stress and in the presence of a threatening out-group. Oxytocin makes people look at eyes longer, encouraging improved accuracy at perceiving emotions. It enhances activity in the TPJ supporting modeling of other people's thinking. Dogs and their owners secrete oxytocin increasing the amount of eye contact between them. It is associated with pair bonding. Brizendine explains that oxytocin and dopamine production are stimulated by ovarian estrogen at the onset of puberty, encouraging girls to connect and bond with their girlfriends, reducing stress, and exclude the out-group. It is central to female mammals wanting to nurse, nursing, and remembering their child. Its effects are context dependent and so is the regulation of the genes that control oxytocin. Variants of a gene CD38 which facilitates oxytocin secretion from neurons are associated with differing levels of activation of the fusiform face area when looking at faces. Sapolsky describes an oxytocin receptor gene variant that is associated with children showing: Extreme aggression, A callous unemotional style; foreshadowing adult psychopathy. And another receptor gene variant is associated with childhood social disconnection and unstable adult relationships. Gene/environment interactions complicate the interpretation of the presence of particular gene variants. Hypothalamic neurons send projections to: ventral tegmentum which also becomes more receptive during child birth, nucleus accumbens, hippocampus, amygdala where it inhibits the central amygdala suppressing fear & anxiety consistently in men while still allowing women to respond to threats to their infants, frontal cortex, olfactory network where it helps new rat mums to learn the smell of their offspring; where oxytocin prepares the brain for in-group bonding, out-grouping, birth and maternal behavior. Outside the brain hypothalamic neurons in females send oxytocin to the posterior pituitary where it enters the blood stream stimulating uterine contraction during labor & supporting milk production for weaning. Disorders associated with oxytocin abnormalities include ASD.

- In non-human mammals it processes interoceptive signals indicate the body's internal homeostatic state: Pain, Fatigue; seconds to minutes before. The signals are conveyed to the CNS via unmyelinated C fibers or lightly myelinated A delta fibers. Damasio suggests this is key to the fabrication of feelings, allowing interaction with the surrounding chemical environment and cross talk between axons. These signals operate unconsciously unless mapped by feelings into consciousness. The interoceptive 'networks': default mode network; project to brain regions that implement social emotions.
.
The ACC focuses the internal signals into high level 'gut intuitions.'
Pain emerged as a mental experience, Damasio asserts, constructed by the mind using mapping structures and events provided by nervous systems. But feeling pain is supported by older biological functions that support homeostasis. These capabilities reflect the organism's underlying emotive processes that respond to wounds: antibacterial and analgesic chemical deployment, flinching and evading actions; that occur in organisms without nervous systems. Later in evolution, after organisms with nervous systems were able to map non-neural events, the components of this complex response were 'imageable'. Today, a wound induced by an internal disease is reported by old, unmyelinated C nerve fibers. A wound created by an external cut is signalled by evolutionarily recent myelinated fibers that result in a sharp well-localized report, that initially flows to the dorsal root ganglia, then to the spinal cord, where the signals are mixed within the dorsal and ventral horns, and then are transmitted to the brain stem nuclei, thalamus and cerebral cortex. The pain of a cut is located, but it is also felt through an emotive response that stops us in our tracks. Pain amplifies the aggression response of people by interoceptive signalling of brain regions providing social emotions including the PAG projecting to the amygdala; making aggressive people more so and less aggressive people less so. Fear of pain is a significant contributor to female anxiety. Pain is the main reason people visit the ED in the US. Pain is mediated by the thalamus and nucleus accumbens, unless undermined by sleep deprivation. catches the ACC's

pain, anxiety is manifested in the amygdala mediating inhibition of dopamine rewards. Anxiety disorders are now seen as a related cluster, including PTSD, panic attacks, and phobias. Major anxiety, is typically episodic, correlated with increased activity in the amygdala, results in elevated glucocorticoids and reduces hippocampal dendrite & spine density. Some estrogen receptor variants are associated with anxiety in women. Women are four times more likely to suffer from anxiety. Louann Brizendine concludes this helps prepare mothers, so they are ready to protect their children. Michael Pollan concludes anxiety is fear of the future. Sufferers of mild autism often develop anxiety disorders. Treatments for anxiety differ. 50 to 70% of people with generalized anxiety respond to drugs increasing serotonin concentrations, where there is relief from symptoms: worry, guilt; linked to depression, which are treated with SSRIs (Prozac). Cognitive anxiety (extreme for worries and anxious thoughts) is also helped by yoga. But many fear-related disorders respond better to psychotherapy: psychoanalysis, and intensive CBT. Tara Brach notes that genuine freedom from fear is enabled by taking refuge.
, disgust is a universal human emotion. Pinker notes it has its own facial expression and is codified in food taboos. The mind must be associated with the proximate environment and parents minimize the risk for their omnivorous children by teaching them what foods to eat and what to avoid. The children's minds are initially receptive to trying all foods but their brains subsequently lock in on the foods they have experienced. These parental choices are affected by schematic influence on what has been beneficial. Adolescent's brain developments undermine these constraints enabling intergroup transfers. Disgust is modulated by the insula cortex which projects signals to the amygdala. Adult humans merge moral and physical disgust enabling metaphorical out grouping. , embarrassment,
social exclusion especially
in adolescence in humans supports the transition from a juvenile configuration, dependent on parents and structured to learn & logistically transform, to adult optimized to the proximate environment. And it is staged, encouraging male adolescents to escape the hierarchy they grew up in and enter other groups where they may bring in: fresh ideas, risk taking; and alter the existing hierarchy: Steve Jobs & Steve Wozniak, Bill Gates & Paul Allen; while females become highly focused on friendships and communications. It marks the beginning of Piaget's formal operational stage of cognitive development. The limbic, autonomic and hormone networks are already deployed and functioning effectively. The frontal cortex has to be pruned: winning neurons move to their final highly connected positions, and are myelinated over time. The rest dissolve. So the frontal lobe does not obtain its adult configuration and networked integration until the mid-twenties when prefrontal cortex control becomes optimal. The evolutionarily oldest areas of the frontal cortex mature first. The PFC must be iteratively customized by experience to do the right thing as an adult. Adolescents: - Don't detect irony effectively. They depend on the DMPFC to do this, unlike adults who leverage the fusiform face area.
- Regulate emotions with the ventral striatum while the prefrontal cortex is still being setup. Dopamine projection density and signalling increase from the ventral tegmentum catalyzing increased interest in dopamine based rewards. Novelty seeking allows for creative exploration which was necessary to move beyond the familial pack. Criticisms do not get incorporated into learning models by adolescents leaving their risk assessments very poor. The target of the dopamine networks, the adolescent accumbens, responds to rewards like a gyrating top - hugely to large rewards, and negatively to small rewards. Eventually as the frontal regions increase in contribution there are steady improvements in: working memory, flexible rule use, executive organization and task shifting. And adolescents start to see other people's perspective.
- Drive the cellular transformations with post-pubescent high levels of testosterone in males, and high but fluctuating estrogen & progesterone levels in females. Blood flow to the frontal cortex is also diverted on occasion to the groin.
- Peer pressure is exceptionally influential in adolescents. Admired peer comments reduce vmPFC activity and enhance ventral striatal activity. Adults modulate the mental impact of socially mean treatment: the initial activation of the PAG, anterior cingulate, amygdala, insula cortex; which generate feelings of pain, anger, and disgust, with the VLPFC but that does not occur in adolescents.
- Feel empathy intensely, supported by their rampant emotions, interest in novelty, ego. But feeling the pain of others can induce self-oriented avoidance of the situations.

as one and the same. The ACC's abnormalities
being associated with major depression is a debilitating episodic state of extreme sadness, typically beginning in late teens or early twenties. This is accompanied by a lack of energy and emotion, which is facilitated by genetic predisposition - for example genes coding for relatively low serotonin levels, estrogen sensitive CREB-1 gene which increases women's incidence of depression at puberty; and an accumulation of traumatic events. There is a significant risk of suicide: depression is involved in 50% of the 43,000 suicides in the US, and 15% of people with depression commit suicide. Depression is the primary cause of disability with about 20 million Americans impacted by depression at any time. There is evidence of shifts in the sleep/wake cycle in affected individuals (Dec 2015). The affected person will experience a pathological sense of loss of control, prolonged sadness with feelings of hopelessness, helplessness & worthlessness, irritability, sleep disturbances, loss of appetite, and inability to experience pleasure. Michael Pollan concludes depression is fear of the past. It affects 12% of men and 20% of women. It appears to be associated with androgen deprivation therapy treatment for prostate cancer (Apr 2016). Chronic stress depletes the nucleus accumbens of dopamine, biasing humans towards depression. Depression easily leads to following unhealthy pathways: drinking, overeating; which increase the risk of heart disease. It has been associated with an aging related B12 deficiency (Sep 2016). During depression, stress mediates inhibition of dopamine signalling. Both depression and stress activate the adrenal glands' release of cortisol, which will, over the long term, impact the PFC. There is an association between depression and additional brain regions: Enlarged & more active amygdala, Hippocampal dendrite and spine number reductions & in longer bouts hippocampal volume reductions and memory problems, Dorsal raphe nucleus linked to loneliness, Defective functioning of the hypothalamus undermining appetite and sex drive, Abnormalities of the ACC. Mayberg notes ACC area 25: serotonin transporters are particularly active in depressed people and lower the serotonin in area 25 impacting the emotion circuit it hubs, inducing bodily sensations that patients can't place or consciously do anything about; and right anterior insula: which normally generates emotions from internal feelings instead feel dead inside; are critical in depression. Childhood adversity can increase depression risk by linking recollections of uncontrollable situations to overgeneralizations that life will always be terrible and uncontrollable. Sufferers of mild autism often develop depression. Treatments include: CBT which works well for cases with below average activity of the right anterior insula (mild and moderate depression), UMHS depression management, deep-brain stimulation of the anterior insula to slow firing of area 25. Drug treatments are required for cases with above average activity of the right anterior insula. As of 2010 drug treatments: SSRIs (Prozac), MAO, monoamine reuptake inhibitors; take weeks to facilitate a response & many patients do not respond to the first drug applied, often prolonging the agony. By 2018, Kandel notes, Ketamine is being tested as a short term treatment, as it acts much faster, reversing the effect of cortisol in stimulating glutamate signalling, and because it reverses the atrophy induced by chronic stress. Genomic predictions of which treatment will be effective have not been possible because: Not all clinical depressions are the same, a standard definition of drug response is difficult;.
- Has a bridging role between the empathetic and
self-interested pain monitor. Sapolsky
notes the ACC is essential for learning fear is an emotion which prepares the body for time sensitive action: Blood is sent to the muscles from the gut and skin, Adrenalin is released stimulating: Fuel to be released from the liver, Blood is encouraged to clot, and Face is wide-eyed and fearful. The short-term high priority goal, experienced as a sense of urgency, is to flee, fight or deflect the danger. There are both 'innate' - really high priority learning - which are mediated by the central amygdala and learned fears which are mediated by the BLA which learns to fear a stimulus and then signals the central amygdala. Tara Brach notes we experience fear as a painfully constricted throat, chest and belly, and racing heart. The mind can build stories of the future which include fearful situations making us anxious about current ideas and actions that we associate with the potential future scenario. And it can associate traumatic events from early childhood with our being at fault. Consequent assumptions of our being unworthy can result in shame and fear of losing friendships. The mechanism for human fear was significantly evolved to protect us in the African savanna. This does not align perfectly with our needs in current environments: U.S. Grant was unusually un-afraid of the noise or risk of guns and trusted his horses' judgment, which mostly benefited his agency as a modern soldier.
and conditioned avoidance by
observation alone through an intermediate step of shared
representation of self. He concludes "At its core
the ACC is about self-interest, with caring about the
other person in pain as an add-on."

- Benefits
- Part A: Hospital inpatient insurance. As of Dec 2013 Medicare pays for home care in only limited circumstances, such as when a person needs temporary nursing care after a hospitalization. Part A covers 20 days of inpatient rehabilitation at a SNF after discharge from inpatient care at a hospital.
- Part B: Medical insurance for non-hospital services including: doctor visits, tests, injectable drugs, ambulances, physical therapy;
- Part C: Medicare Advantage
- Part D: indirect prescription drug coverage The MMA prohibits Medicare from directly negotiating drug prices.
- Eligibility
- All persons 65 years of age or older who are legal residents for at least 5 years. If they or a spouse have paid Medicare taxes for 10 years the Medicare part A payments are waived. Medicare is legislated to become the primary health plan.
- Persons under 65 with disabilities who receive SSDI.
- Persons with specific medical conditions:
- Have end stage renal disease or need a kidney transplant.
- They have ALS.
- Some beneficiaries are dual eligible.
- Part A requires the person has been admitted as an inpatient at a hospital. This is constrained by a rule that they stay for three days after admission.
- Sign-up
- Part A has automatic sign-up if the person is drawing social security. Otherwise the person must sign-up for Part A and Part B.
- Should sign-up for Part B during the Initial Enrollment Period, of seven months centered around 65th birthday, online or at a social security office. But if still covered by spouse's insurance or not yet retired then may only join during the 3 month general enrollment period (January to March) each year, with coverage initiated the following July. Incremental yearly 10% penalties apply for not signing up at 65. These penalties apply to all subsequent premiums.

business. The ACA is the Patient Protection and Affordable Care Act amended by the Health Care and Education Reconciliation Act of 2010 (Obama care). In part it is designed to make the health care system costs grow slower. It aims to do this by: increasing competition between insurers and providers, offering free preventative services to limit the development of serious illnesses, constraining patients' use of expensive services, constraining the growth of payments to Medicare providers and piloting new ways for PCPs to manage patient care to keep patients away from costly E.D.s. It funds these changes with increased taxes on the wealthy. It follows an architecture developed by Heritage Action's Butler, Moffit, Haislmaier extended by White House OMB health policy advisor Ezekiel Emanuel & architect Jeanne Lambrew. The Obama administration drafting team included: Bob Kocher; allowing it to integrate ideas from: Dartmouth Institute's Elliot Fischer (ACO). The ACA did not include a Medicare buy in (May 2016). The law includes: - Alterations, in title I, to how health care is paid for and who is covered. This has been altered to ensure
- Americans with preexisting conditions get health insurance cover - buttressed by mandating community rating and
- That they are constrained by the individual mandate to have insurance but the requirement was supported by subsidies for the poor (those with incomes between 100 & 400% of the federal poverty line).
- Children, allowed to, stay on their parents insurance until 26 years of age.
- Medicare solvency improvements.
- Medicaid expansion, in title II: to poor with incomes below 138% of the federal poverty line; an expansion which was subsequently constrained by the Supreme Court's ruling making expansion an optional state government decision.
- Hospital Readmissions Reduction Program (HRRP) which was enforced by CMS mandated rules finalized in 2011 and effected starting Oct 2012.
- Medical home models.
- Community transformation grants support the transformation of low income stressed neighborhoods to improve their lifestyles and health.
- Qualifications for ACOs. Organizations must:
- Establish a formal legal structure with shared governance which allows the ACO to distribute shared savings payments to participating providers and suppliers.
- Participate in the MSSP for three or more years.
- Have a management structure.
- Have clinical and administrative systems.
- Include enough PCPs to care for Medicare FFS patient population (> 5000) assigned to the ACO.
- Be accountable for the quality and cost of care provided to the Medicare FFS patient population.
- Have defined processes to promote: Evidence-based medicine, Patient-centeredness, Quality reporting, Cost management, Coordination of care;
- Demonstrate it meets HHS patient-centeredness criteria including use of patient and caregiver assessments and individualized care plans.
- CMMI Medicare payment experimentation.
- Requirements that pharmaceutical companies must report payments made to physicians (Sunshine Act).
- A requirement that chain restaurants must report calorie counts on their menus.

- Part A has automatic sign-up if the person is drawing social security. Otherwise the person must sign-up for Part A and Part B.
- Should sign-up for Part B during the Initial Enrollment Period, of seven months centered around 65th birthday, online or at a social security office. But if still covered by spouse's insurance or not yet retired then may only join during the 3 month general enrollment period (January to March) each year, with coverage initiated the following July. Incremental yearly 10% penalties apply for not signing up at 65. These penalties apply to all subsequent premiums.

CMS program's purpose is to reward providers for reducing
total cost of care for patients through prevention, disease
management, and coordination aims to transfer information between the patient and each care participant as required and establish accountability by defining who is responsible for each care delivery activity, the extent of that responsibility and when that responsibility will be transferred to other care participants or the patient and family. Successful care coordination requires face-to-face interactions. It also requires aligned incentives (ACO, Bundled payments). AHRQ defines quality measures for care coordination. The situation is usually complex and adaptive due to the interactions of all the providers, settings, the patients' preferences, and the number of physical health problems, treatments, and the patients' social situation. The potentially exponential increase in complexity as the number of these factors present increases leads to patient hot spots requiring explicit proactive coordination of care. It is argued that care coordination must include six specific activities: - Determination and updating of care coordination needs: Needs assessment should identify preferences and goals, current situation and past history. It needs to be updated periodically and after new diagnosis and other changes in health or functional status.
- Creation and updating of proactive plan of care
- Communication
- Facilitation of transitions: typical transition problems are detailed by Project Boost. A challenging issue with transitions is what to do when there is no resource to take over the coordination role in the handoff.
- Connection to community resources: Community resources are any service or program outside the health care system that may support a patient's health and wellness.
- Alignment of resources with population needs: need to see the system-level, assess the needs of populations to identify and address gaps in services.

- CMMI is the center for Medicare and Medicaid Innovation. It is a test bed for new ways of financing and delivering care. It allowed Congress to institutionalize innovation sending a signal to providers that they would be participating in CMS driven programs that could become mainstream. It funds evaluations of innovative health care models. Under the ACA if the HHS secretary finds any of its projects would reduce Medicare spending without harming the quality of care the projects may be expanded nationwide. The CBO estimates the CMMI will save $34 billion between 2016 and 2026. CMMI projects include:
- Medicare will make a bundled payment for hip and knee replacement surgery (CJR) and 90 days of follow-up care forcing hospitals to work closely with doctors, nursing homes and home health agencies.
- New ways to pay for prescription drugs, medical devices, cancer care (OCM).
- HHS secretary has invoked his 3021 authority to institute DPP.

to test various payment systems including shared savings is the Medicare Shared Savings Program. The program began in 2012 with 3 year term contracts. ACO Physician groups and hospitals are eligible to participate but there must be primary care physicians in the ACO. Participating ACOs must serve > 5000 Medicare beneficiaries. The potential for a bonus payment is based on Medicare cost savings and quality metrics. Two payment models are available. Only one has downside risk involved. CMS included 'robust' quality measures to monitor the quality of care provided and beneficiary satisfaction (see fact sheet 'Improving Quality of Care for Medicare Patients: Accountable Care Organizations'). and partial
capitation is a global payment for all care for a patient during a specified time period. It forces the provider of care to take a high risk. Managing the risk implies successful population health management. .

- Action potentials
are the actively generated waves of voltage change was formulated by Julius Bernstein to describe the generation and propagation of an action potential along a neuron's cell membrane. It elegantly established how a resting potential of -70 millivolts was maintained until the selective permeability of the membrane is broken down briefly (0 millivolts) during the action potential, utilizing energy stored in concentration gradients of ions.

Adrian showed the action potential to be an all-or-nothing signal, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy. . Consequently
Adrian extended the neuron
doctrine is cell theory applied to the brain. Anatomist Santiago Cajal developed ground breaking strategies to view individual neurons and concluded that nerve cells (neurons) are the fundamental building blocks and signalling units of the brain. - Looking at newborn brains helped Cajal to see individual neurons because there were less present than in mature higher animals.
- Using Golgi's silver stain only 1% of neurons are stained but that 1% is fully stained revealing the full anatomy of single neurons. This allowed Cajal to develop observations which he used to formulate the four principles of the neuron doctrine:
- Neuron is the fundamental structural and functional element of the brain with the dendrites and axon having different roles.
- The terminals of one neuron's axon communicate with the dendrites of other neurons via specialized sites that include a small gap.
- Connection specificity argues that neurons only form synapses and communicate with certain targets to construct a neural circuit. Typically a single neuron makes contact with dendrites of many target cells, allowing broad dissemination of information.
- Dynamic polarization Cajal argued was provided by signals only traveling in one direction in a neural circuit.

It is a simple function that may be selected for classifying a novel instance x as belonging to a particular class within the training data in machine learning. The hyperplane (bias + x(t) weight) = 0 forms the decision boundary. The orientation of the decision boundary is determined by the vector weight. The bias shifts the decision boundary by a constant amount. The sigmoid function is one activation function for use with neural networks which does not suffer unstable convergence (like the linear activation function), or produce a limiting binary output (like a binary function). One effective alternative to selecting a direct sigmoid function is to apply a class conditional density estimation and Bayes rule to form the classifier.

- Adair three-circles model
is a tool for leadership now aims to develop plans and strategies which ensure effective coordination to improve the common good of the in-group. Pinker notes the evolved pressure of social rivalry associating power with leadership. Different evolved personality types reinforced during development provided hunter-gatherer bands with alternate adult capabilities for coping with the various challenges of the African savanna. As the situation changed different personalities would prove most helpful in leading the band. Big men, chiefs and leaders of early states leveraged their power over the flow of resources to capture and redistribute wealth to their supporters. As the environmental state changed and began threatening the polity's fitness, one leader would be abandoned, replaced by another who the group hoped might improve the situation for all. Sapolsky observes the disconnect that occurs between power hierarchies and wisdom in apes. In modern Anglo-American style corporations, which typically follow Malthus, and are disconnected from the superOrganism nest site, the goal of leadership has become detached from the needs of this broader polity, instead: seeking market and revenue growth, hiring and firing workers, and leveraging power to reduce these commitments further. Dorner notes that corporate executives show an appreciation of how to control a CAS. Robert Iger with personality types: Reformer, Achiever, Investigator; describes his time as Disney CEO, where he experienced a highly aligned environment, working to nurture the good and manage the bad. He notes something is always coming up. Leadership requires the ability to adapt to challenges while compartmentalizing. John Boyd: Achiever, Investigator, Challenger; could not align with the military hierarchy but developed an innovative systematic perspective which his supporters championed and politicians leveraged. John Adair developed a modern leadership methodology based on the three-circles model.

distinct but interacting:
- Individual needs - which must be supported by the leader
to ensure the team member's self-motivation is not
undermined.
- Group needs - Each member's social emotions are emotions that are induced in response to other people's signals, are implemented by specific brain regions including: Prefrontal cortex, Insula cortex, Anterior cingulate cortex, Amygdala; receive lots of projections from interoceptive networks. Sapolsky asserts in the moments just before we prioritize a consequential act the process is less rational and autonomous than we assume. There are many significant signals from the prior seconds to minutes that effect social emotions:
- Our brains respond subliminally to skin color very quickly: Amygdala activates, Fusiform face area activates; prior to the conscious stream activating the anterior cingulate and DLPFC which then inhibit the amygdala.
- Social dominance is culture independent and accurately subliminally assessed after a 40-millisecond exposure. Stable status relations activate the ventromedial prefrontal cortex and DLPFC, while a dynamic situation also activates the amygdala.
- People who are subliminally judged attractive by the medial orbitofrontal cortex are considered kinder, smarter and more honest. They are given more breaks.
- Faces and eyes in particular are most important subliminal cues. They are monitored by the fusiform. People respond more appropriately under the subliminal influence of eyes.
- Olfactory sensors send more direct projections to the limbic network than other sensory networks. Pheromones signal fear activating the amygdala.
- Observing pain responses in others results in empathy even among young children.
- Words are important emotional signals providing unconscious priming of social responses. Kahneman & Tversky demonstrated how the phrase '95% survival rate' is found to be a more acceptable choice than '5% death rate'. Sapolsky notes that prosocial word priming fosters cooperation with antisocial word priming doing the opposite.
- Cultural objects such as visible: flags, team badges; subliminally modify in-group outgroup decisions.
- The presence of women in a situation alters the responses of men: Increased risk-taking, more focus on luxuries, increased aggression; in circumstances where conflict is already encouraged but not when status is achieved prosocially.
- Physical environment shapes behavior as demonstrated by Philip Zimbardo and leveraged in broken windows policing.
- Bodily adjustments to sensory structures introduce adaptive complexity, with the brain being influenced to become more sensitive and alter the sensor networks to make some more sensitive. But these adaptations also vary culturally. Collectivist cultures focus on a visual scene's surrounding contextual information while people from individualistic cultures focus on the focal object!

- Cascade of goals and strategies is developed by top down and bottom up discussions allowing detail to be added along with alignment and buy in. In Japan, lifelong employment supported this process. The individual focused merit ratings used in Western management practice undermines the process in Deming's view (deadly disease 3).
- The goals, strategies and success measures should be rigorously documented. In the original paper and fax processes in Japan each goal, its strategies, measures and resources were documented in a planning table. The whole activity became coordinated by a house of quality. In AWF the planning table is replaced by a bullet point infinite labelled goal in the execution schematic plan with a structured status block allowing easy visualization of the goal network.

Evolution indicates fitness is, according to Dawkins, a suitcase word with at least five meanings in biology: - Darwin and Wallace thought in terms of the capacity to survive and reproduce, but they were considering discrete aspects such as chewing grass - where hard enamel would improve the relative fitness.
- Population geneticists: Ronald Fisher, Sewall Wright, J.B.S. Haldane; consider selection at a locus where for a genotype: green eyes vs blue eyes; one with higher fitness can be identified from genotypic frequencies and gene frequencies, with all other variations averaged out.
- Whole organism 'integrated' fitness. Dawkins notes there is only ever one instance of a specific organism. Being unique, comparing the relative success of its offspring makes little sense. Over a huge number of generations the individual is likely to have provided a contribution to everyone in the pool or no one.
- Inclusive fitness, where according to Hamilton, fitness depends on an organism's actions or effects on its children or its relative's children, a model where natural selection favors organs and behaviors that cause the individual's genes to be passed on. It is easy to mistakenly count an offspring in multiple relative's fitness assessments.
- Personal fitness represents the effects a person's relatives have on the individual's fitness [3]. When interpreted correctly fitness [4] and fitness [5] are the same.

- Adaptive unconscious is
Timothy Wilson's idea of a set of high-level cognitive
processes, which interpret 'information' quickly without
conscious awareness. It supports: decision making integrates situational context, state and signals to prioritize among strategies and respond in a timely manner. It occurs in all animals, including us and our organizations:
- Individual human decision making includes conscious and unconscious aspects. Situational context is highly influential: supplying meaning to our general mechanisms, & for robots too. Emotions are important in providing a balanced judgement. The adaptive unconscious interprets percepts quickly supporting 'fast' decision making. Conscious decision making, supported by the: DLPFC, vmPFC and limbic system; can use slower autonomy. The amygdala, during unsettling or uncertain social situations, signals the decision making regions of the frontal lobe, including the orbitofrontal cortex. The BLA supports rejecting unacceptable offers. Moral decisions are influenced by a moral decision switch. Sleeping before making an important decision is useful in obtaining the support of the unconscious in developing a preference. Word framing demonstrates the limitations of our fast intuitive decision making processes. And prior positive associations detected by the hippocampus, can be reactivated with the support of the striatum linking it to the memory of a reward, inducing a bias into our choices. Prior to the development of the PFC, the ventral striatum supports adolescent decision making. Neurons involved in decision making in the association areas of the cortex are active for much longer than neurons participating in the sensory areas of the cortex. This allows them to link perceptions with a provisional action plan. Association neurons can track probabilities connected to a choice. As evidence is accumulated and a threshold is reached a choice is made, making fast thinking highly adaptive. Diseases including: schizophrenia and anorexia; highlight aspects of human decision making.
- Organisations often struggle to balance top down and distributed decision making: parliamentry government must use a process, health care is attempting to improve the process: checklists, end-to-end care; and include more participants, but has systemic issues, business leaders struggle with strategy.

The sleep stages follow Pre-sleep and include: Stage one characterized by light sleep and lasting 10 minutes, Stage two where theta waves and sleep spindles occur, Stage three and Stage four together represent deep slow-wave sleep (SWS) with delta waves, Stage five is REM sleep; sleep cycles last between 90-110 minutes each and as the night progresses SWS times reduce and REM times increase.

operation of the brain's reward
network includes: the nucleus accumbens, which responds to dopamine signalling, the striatum & the PFC which control and motivate using rewards.
's regulatory regions, altering
the anticipation of rewards. Addictive drugs
mediate the receptors, in biological cells these proteins are able to span the cell membrane and present an active site which is tailored to interact with a specific signal. When the receptor pairs with its signal, its overall shape changes resulting in changes in the part internal to the cell which can be relayed by the cells signalling infrastructure. In neuron synapses one type of receptor (fast) is associated with an ion channel. The other (slow) is associated with a signalling enzyme chain and modulates the neuron's response. of the
reward network, increasing dopamine is a synaptic signal supporting generalized goal-directed behavior & anticipation of reward. Its significance is that the receptors that detect the signal are of the slow acting type and are used to alter (modulate) the response of fast acting dopaminergic neural circuits in which the receptors are deployed (LTP). The signal detects significant changes including predictions of models and actual results which differ unexpectedly. Dopamine is released primarily by neurons of the ventral tegmental area and the substantia nigra. The dopamine network architecture is designed to signal the possibility of any type of reward: Norm violation punishment, Winning a lottery, & Misfortune of an envied competitor. Dopamine signalling: - Rescales continuously to accommodate the range of intensity offered by different stimuli. So dopamine's responses to any reward habituate. GABA is released by some tegmental neurons to induce habituation. This allows addictions to develop.
- Reflects the anticipation of reward. It supports establishment of a relationship between a signal, working for a reward and obtaining the reward, but subsequently dopamine is mainly released encouraging the work, right after the signal supporting anticipation of the reward. Anticipation requires learning and is reflected in hippocampus activity. That explains context dependent cravings. And the learning architecture means reliable cues become rewarding. The accumbens supports willpower. And dopamine
- Promotes goal-oriented behavior needed to obtain & likely to achieve the reward - through the dopamine projections to the prefrontal cortex. That makes dopamine central to:
- Motivation. This binding fails in depression - due to stress and in anxiety - due to signals from the amygdala.
- The prefrontal cortex's mesocortically stimulated support for willpower to act to delay rewards. To sustain work for delayed rewards additional dopamine is released based on the length of the delay and the rewards uncertainty (modelled in the dorsolateral prefrontal cortex - which promotes the long term and the ventromedial prefrontal cortex - which promotes the short term) and the anticipated size of the reward (modelled in the accumbens). Impulsiveness in ADHD is reflected in abnormal dopamine processing. Addictive drugs bias the dopamine network towards impulsiveness.
- Is lowered by certain gene variants which induce: less dopamine in the synapse, fewer receptors, lower responsiveness of receptors; associated with (as tiny effects in hugely varying social scenarios): sensation seeking, risk taking, attentional problems, extroversion; where:
- The receptor D4's gene shows high variability. The D47R form is relatively unresponsive to dopamine.
- Dopamine is degraded by COMT. The COMT gene includes a variant which is highly efficient reducing dopamine signalling but with complicating gene/environment interactions.
- Dopamine is removed from the synapse by a reuptake transporter DAT.

The cerebral cortex is a pair of large folded sheets of brain tissue, one on either side of the top of the head connected by the corpus callosum. It includes the occipital, parietal, temporal and frontal lobes. . The learned
association of the situation with the reward makes addiction

where the sufferer must remain vigilant to avoid relapse

addictive drug alters the reward network. The neurons, specialized eukaryotic cells include channels which control flows of sodium and potassium ions across the massively extended cell membrane supporting an electro-chemical wave which is then converted into an outgoing chemical signal transmission from synapses which target nearby neuron or muscle cell receptors. Neurons are supported by glial cells. Neurons include a: - Receptive element - dendrites
- Transmitting element - axon and synaptic terminals. The axon may be myelinated, focusing the signals through synaptic transmission, or unmyelinated - where crosstalk is leveraged.

command which specifies the prefix used by the dark web generator is a Perl script, typically launched as a child process within the configuration editor, by clicking 'generate web', which executes frame configuration file instructions merging the configuration variables with an HTML template file to generate target web pages. The configuration instructions can be tailored by filters from the configuration file specified filter file. execution plan are lists of strategies. Each strategy is numbered with a unique infinite label. monitored region is a part of a child execution plan that has a link from the 'update' or 'PDCA' keyword within a strategy's status description in the associated parent execution plan. With appropriate filter file settings (addstatepref, addstatetag, statecase, statefile, statelist) the dark web generator will monitor changes to the region starting at the infinite label for the strategy in the child plan and each line following it until a higher labeled strategy is detected. Any changes within the region will be indicated by linking the parent's status description 'done' keyword to a status file description and changing the 'done' link status to unused. state

- ADHD
is attention-deficit/hyperactivity disorder, a chronic
condition including hyperactivity, impulsiveness and low
attention. Dopamine is a synaptic signal supporting generalized goal-directed behavior & anticipation of reward. Its significance is that the receptors that detect the signal are of the slow acting type and are used to alter (modulate) the response of fast acting dopaminergic neural circuits in which the receptors are deployed (LTP). The signal detects significant changes including predictions of models and actual results which differ unexpectedly. Dopamine is released primarily by neurons of the ventral tegmental area and the substantia nigra. The dopamine network architecture is designed to signal the possibility of any type of reward: Norm violation punishment, Winning a lottery, & Misfortune of an envied competitor. Dopamine signalling:
- Rescales continuously to accommodate the range of intensity offered by different stimuli. So dopamine's responses to any reward habituate. GABA is released by some tegmental neurons to induce habituation. This allows addictions to develop.
- Reflects the anticipation of reward. It supports establishment of a relationship between a signal, working for a reward and obtaining the reward, but subsequently dopamine is mainly released encouraging the work, right after the signal supporting anticipation of the reward. Anticipation requires learning and is reflected in hippocampus activity. That explains context dependent cravings. And the learning architecture means reliable cues become rewarding. The accumbens supports willpower. And dopamine
- Promotes goal-oriented behavior needed to obtain & likely to achieve the reward - through the dopamine projections to the prefrontal cortex. That makes dopamine central to:
- Motivation. This binding fails in depression - due to stress and in anxiety - due to signals from the amygdala.
- The prefrontal cortex's mesocortically stimulated support for willpower to act to delay rewards. To sustain work for delayed rewards additional dopamine is released based on the length of the delay and the rewards uncertainty (modelled in the dorsolateral prefrontal cortex - which promotes the long term and the ventromedial prefrontal cortex - which promotes the short term) and the anticipated size of the reward (modelled in the accumbens). Impulsiveness in ADHD is reflected in abnormal dopamine processing. Addictive drugs bias the dopamine network towards impulsiveness.
- Is lowered by certain gene variants which induce: less dopamine in the synapse, fewer receptors, lower responsiveness of receptors; associated with (as tiny effects in hugely varying social scenarios): sensation seeking, risk taking, attentional problems, extroversion; where:
- The receptor D4's gene shows high variability. The D47R form is relatively unresponsive to dopamine.
- Dopamine is degraded by COMT. The COMT gene includes a variant which is highly efficient reducing dopamine signalling but with complicating gene/environment interactions.
- Dopamine is removed from the synapse by a reuptake transporter DAT.

hierarchy: Steve Jobs was an innovative entrepreneur who integrated art and culture with engineering, and is responsible for: the strong sexual selection force of the: Macintosh, iPod, iPad and iPhone; and their dedicated fan base. He helped John Lasseter and Ed Catmull turn Pixar into a digital animation powerhouse and became Disney's largest shareholder when he and Robert Iger integrated Disney and Pixar. He cofounded Apple Computer with Steve Wozniak where Wozniak designed a particularly simple microprocessor based computer, the Apple 1 and Jobs made it elegant. Struck by the relative simplicity and ease of use of PARC's Alto, Jobs and Wozniak began building the Lisa. But Jobs decided it was flawed and took a small group aside to build the Macintosh which the whole team were happy to sign their names on the inside. Born February 24th 1955, Steve's birth mother Joanne Schieble was forced by her father to have the boy adopted rather than allow her to marry his Muslim Syrian birth father, Abdulfattah Jandali, the last of nine children of a hugely wealthy trader, Walter Isaacson explains. The baby was adopted by Paul Reinhold Jobs, a highly practical mechanic and a mild kind father, and Clara Hagopian, also sweet-humored, and when Steve was two they adopted Patty. The Jobs lived in an Eichler (a design inspired by Frank Lloyd Wright), in Mountain View, California, which had a strong influence on Steve, as he explained to Isaacson, "Eichler did a great thing. His houses were smart and cheap and good. They brought clean design and simple taste to lower income people. They had awesome little features, like radiant heating in the floors. You put carpet on them, and we had nice toasty floors when we were kids." Steve Jobs knew early on that he was adopted, which pained him supporting development of his Challenger personality type. It was also clear to Steve that he was unlike his adopted parents, Paul and Clara Jobs, who stressed to him that they picked him specifically and that he was special. They tolerated Steve's high risk activities and ensured he was safe when problems occurred. Paul Jobs impressed Steve as a child, with his valuing quality workmanship, and his practical capabilities. Paul could repair any car and Steve became interested in the electronics aspects. He was helped by neighbors who were electrical engineers: Larry Lang; the geographic cluster that formed around Hewlett Packard and Intel. And he then joined a neighborhood electronics club where he was introduced to Steve Wozniak. But the young Steve Jobs was shocked when he discovered his father did not correctly understand some aspects of the world, and Steve realized he was much more intelligent than his parents Paul and Clara. With their support he followed his curiosity and resisted any attempt to stop him. His powerful drive made his parents, teachers, local business leaders: Bill Hewlett, Nolan Bushnell; and coaches go along. At Reed College he pushed to attend courses he was interested in: calligraphy; rather than follow the syllabus, and they let him. They even allowed him to continue when he stopped his parents from paying more tuition. His stressed individualist continually sought out gurus: Shunryu Suzuki, Neem Karoli Baba; and visionaries who might help Steve understand who he really was. Jobs became ill with pancreatic cancer which metastasized to his liver. He died on October 5th 2011 and was buried in Palo Alto, California, after a small funeral.

frontal cortex of the cerebral cortex is at the front of the brain. It includes the: prefrontal cortex, motor cortex. Sapolsky asserts it makes you do the harder thing when it's the right thing to do. The frontal cortex supports working memory to sustain focus on a task. It also coordinates the strategic actions necessary to achieve success. It provides impulse control, regulation of emotion, and willpower. The prefrontal cortex maintains focus by deprioritizing currently irrelevant streams of information. The frontal cortex tracks rules. Over a lifetime, that builds into a costly activity. Once it tires, responses become less prosocial. But practice shifts operation of tasks to the cerebellum. The frontal cortex signals the tegmentum and accumbens with the conclusions of its expectancy/discrepancy calculations. The frontal lobe provides executive function, considering bits of information, assessing patterns and then prioritizing the strategies. The frontal lobe is the most recent part of the brain to evolve and involves a disproportionate percentage of primate-unique genes in its development and operation. It does not complete development until the mid-20s. It includes spindle neurons. It is easily damaged. Sapolsky (Nauta) notes that its ventromedial prefrontal cortex is a quasi-member of the limbic system. has to be
pruned: winning neurons, specialized eukaryotic cells include channels which control flows of sodium and potassium ions across the massively extended cell membrane supporting an electro-chemical wave which is then converted into an outgoing chemical signal transmission from synapses which target nearby neuron or muscle cell receptors. Neurons are supported by glial cells. Neurons include a: - Receptive element - dendrites
- Transmitting element - axon and synaptic terminals. The axon may be myelinated, focusing the signals through synaptic transmission, or unmyelinated - where crosstalk is leveraged.

In humans it is still occurring 25 years after birth. It has great impact on long axons, in neurons that project over long distances, where it helps brain inter-region signalling. The long development time of myelination allows for the later myelinated brain regions to be particularly shaped by the proximate environment. over Carlo Rovelli resolves the paradox of time.
Rovelli initially explains that low level physics does not
include time:
- A present that is common throughout the universe does not exist
- Events are only partially ordered. The present is
localized
- The difference between past and future is not foundational.
It occurs because of state that through our blurring appears
particular to us
- Time passes at different speeds dependent on where we are and how fast we travel
- Time's rhythms are due to
the gravitational field
- Our quantized physics shows neither
space nor time, just processes transforming physical
variables.
- Fundamentally there is no time. The basic equations
evolve together with events, not things
Then he
explains how in a physical world without time its perception can
emerge:
- Our familiar time emerges
- Our interaction with the world is partial, blurred,
quantum indeterminate
- The ignorance determines the existence of thermal time
and entropy that quantifies our uncertainty
- Directionality of time is real
but perspectival. The entropy of the world in
relation to us increases with our thermal time. The
growth of entropy distinguishes past from future: resulting in
traces and memories
- Each human is a
unified being because: we reflect the world, we
formed an image of a unified entity by
interacting with our kind, and because of the perspective
of memory
- The variable time: is one
of the variables of the gravitational field.
With our scale we don't

- Regulate emotions are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism.

projection density and signalling, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy.

tegmentum is part of the tegmentum which contains dopamine long system cell bodies (high levels of D(2)). Their axons branch extensively and reach many areas including: Mesolimbic to the limbic system: amygdala, hippocampus; Tegmentostriatal to the nucleus accumbens, Mesocortical to the forebrain including the prefrontal cortex. The terminals are fairly evenly distributed through out layers 1 - 6. So dopamine can modulate input and output excitatory and inhibitory transmissions. If a rodent wins a fight on his home territory, there are long-lasting increases in levels of testosterone receptors enhancing pleasurable effects. The lateral ventral tegmental area is now known to be one of two large adrenergic pathways, along with the locus ceruleus. During child birth the ventral tegmentum deploys more oxytocin receptors increasing its sensitivity to the neuropeptide. catalyzing, an infrastructure amplifier.

the adolescent accumbens is a region of the basal forebrain (striatum) rostral to the preoptic area and immediately adjacent to the septum. The nucleus accumbens was closely associated with the limbic system, mediates the impact of emotion and plays an important role in reinforcement. If a rodent wins a fight on his home territory, there are long-lasting increases in levels of testosterone receptors enhancing pleasurable effects. When prairie voles first mate, epi-genetic state changes are induced in the accumbens to support pair-bonding. The accumbens projects to brain regions associated with movement. The major pathways of dopaminergic neurons begin in the substantia nigra and the ventral tegmental area. The amygdala projects back to the accumbens. The tegmentostriatal system begins in the ventral tegmental area and projects to the nucleus accumbens. The nucleus accumbens includes high levels of D1, D2 and D3 dopamine receptors located on the spine & shafts of dendrites of excitatory cells reduce the transfer of excitation from the dendrites to the cell bodies, so only especially strong excitatory inputs get through to the cell body to elicit excitation. It also has D4 dopamine receptors which are highly variable. The accumbens responds differently to rewards depending on maturity: In juveniles all reward levels result in the same response activity level, During adolescence the accumbens responds to small rewards negatively, and large rewards hugely, In adults the rewards result in measured scaled positive responses. Chronic stress depletes dopamine from the nucleus accumbens biasing humans towards depression. ,

memory is a dominant function of the dorsolateral prefrontal cortex and the areas it connects with. Prefrontal neurons implement an active memory continuing to fire after the signal is gone for potentially dozens of seconds from the inferior temporal cortex (multi-sensory integration area) and lower level sensory neurons characterized by Hubel & Weisel, while the short-term memory task continues. If the prefrontal cortex gets distracted the memory is lost from consciousness. Earl Miller argues the prefrontal cortex implements the rules that decide which working memory neurons will fire (Spring 2017).

high levels of testosterone is a hormone secreted by the testes, ovaries, and adrenal glands, in response to stimulation from the hypothalamic/pituitary/testicular cascade, that makes humans more willing to do what it takes to attain and maintain status, according to Sapolsky. That means players of the Ultimatum Game, if previously given testosterone can become more generous. High testosterone in a fetus masculinizes the brain. Males generate 10 times the amount. It is the trigger for sexual desire in males and females, stimulating the hypothalamus. Testosterone's effect is highly socially contextual so it may encourage acts of kindness or aggression (when challenged). The level of testosterone does not predict which individuals will be aggressive in: Birds, Fish, Mammals including primates. Genes impact the potency of testosterone by altering the enzymes that: Construct it, Convert it to estrogen, code the androgen receptor. This androgen receptor includes a variable polyglutamine repeat which alters the sensitivity to the testosterone signal. The more potent form is associated with boys showing more dramatic 'masculinization' of the cortex. But the detected genetic influences are small. Testosterone decreases activity in the prefrontal cortex and its functional coupling to the amygdala while increasing the coupling between the amygdala & the thalamus. Testosterone shortens the refactory period of amygdaloid & amygdaloid target neurons. This results in impulsive risk taking and more focus on unfamiliar faces and distrust of them. Testosterone increases activity in the ventral tegmentum projecting dopamine to enhance place preference. Winners of fights become more willing to fight in part due to testosterone increasing confidence and optimism and reducing fear and anxiety. And winning at: Chess, Athletics, Stock trades; induces the BNST to add testosterone receptors increasing its sensitivity to the hormone. People become overconfident and overly optimistic.
in males, and high but fluctuating estrogen is a generic term for a number of related steroid hormones each of which works differently. Estrogen: - Is generated in the ovaries. It supports the generation of oxytocin, and so is associated with attachment, nurturing and other affiliative behaviors.
- Supports verbal memory. Removal of ovaries without immediate estrogen replacement therapy degrades verbal memory performance. The HT reduces age-related shrinkage of the PFC, parietal cortex, and temporal lobe in women, and made them less depressed and angry.
- Supports mitochondrial operation in the blood vessels of the brain.
- Contributes to maternal aggression but it can reduce aggression and enhance empathy, depending on brain state. There are two different estrogen receptor types which mediate these conflicting effects. The level of each type of receptor is independently regulated. Different receptor variants are associated with:
- Higher rates of anxiety among women
- Higher rates of antisocial behavior and conduct disorder in men
- Is essential for vaginal lubrication
- Facilitates the elimination of cholesterol
- Has anti-inflammatory and anti-oxidative properties improving response to stress
& progesterone is a steroid hormone. It: - Rarely directly effects areas of the brain. Instead it is converted into other sterioids which have different actions in different brain areas.
- Increases maternal aggression in concert with estrogen by increasing oxytocin release in certain brain regions. However, on its own progresterone decreases aggression and anxiety. It decreases anxiety by entering neurons where it is converted to allopregnanolone which binds to GABA receptors increasing their sensitivity to GABA.

influential in adolescents is Robert Trivers theory to explain the allocation of parental resources to various offspring, from the implications of genetics on the family. Observing that children want to take more than what their parents want to give Trivers concluded a parent should aim to transfer resources depending on the relative benefits to each child and the costs, since each child has the same percentage of the parent's genes. But each child shares only fifty percent of their genes with their siblings so should aim to get resources until the benefit to the others is twice the cost to the child. And the parent may keep back some resources for allocation to further planned offspring. A variety of conflicts ensue:
- In the womb the fetus tries to capture nutrients from the mother at the expense of future children. It ties up the mother's insulin to increase the blood sugar available to it and placing the mother at risk of diabetes. Fathers can assist their offspring in this 'fight with the mother' by supplying imprinted genes that help the offspring capture resources.
- At birth mothers must decide whether to let the baby die. This practice is cross cultural but is considered a depravity by present Western culture. That is probably due to the West having captured a majority of the world's resources for centuries.
- Infants use cuteness to encourage parental investment. A mother's attachment delays until it is clear that the baby will live.
- Infants cry to demand milk. Until weaned the mother won't ovulate limiting her future reproductive potential.
- Young children are in conflict with their father over access to their mother.
- Children are in a position to develop paradoxical tactics to push for more resource allocation.
- Older children may have sexual conflicts with their parents, especially their fathers. Fathers compete with sons for sexual partners in many societies. But this competition is not for their mother.
- Adult children may conflict with their parents over allocation of family resources. This has led to murder.
- Parents attempt to train children to assist the parent's social interests. The implication is that children are wary of their parent's suggestions and typically pay more attention to the advice of their peer group according to Judith Harris.
- Parents sell or trade their children. The price paid for a daughter will likely depend on her virginity. Hence fathers take an interest in their daughters' sexuality.

of the PAG is periaqueductal gray, an ancient core brain structure that projects pain sensations to the amygdala, has a high density of vasopressin and oxytocin receptors and a direct connection to the orbitofrontal cortex, potentially supporting maternal love. It has a critical role in autonomic function, motivated behavior and responses to threats - the dorsal PAG activates during defensive behaviors: freezing immobility, running, jumping, increased blood pressure; while caudal ventrolateral PAG activation results in an immobile relaxed posture. The PAG's enkephalin-producing cells suppress pain. , anterior cingulate is the cingulate gyrus, a rich club hub. Contains many sub-parts: - The anterior cingulate cortex ACC:
- Includes the subgenual ACC and the paragenual ACC, and Brodmann areas 24, 25, 32 and 33.
- The gyrus of the ACC has two functional components, which both operate abnormally in mood disorders: depression, anxiety & bipolar. The
- Rostral/ventral part is involved in emotional processes and autonomic functions. It connects to the hippocampus, amygdala, orbital prefrontal cortex, anterior insula, nucleus accumbens. It is overactive during regular or bipolar depression.
- Caudal part is involved in cognition and the control of behavior. It connects with the dorsal PFC, secondary motor cortex, and posterior cingulate cortex
- Is a central focus of empathy supporting people relating to other's pain. This is dependent on oxytocin.
- In non-human mammals it processes interoceptive signals. The ACC focuses the internal signals into high level 'gut intuitions.' Pain catches the ACC's attention.
- Performs discrepancy detection from the outcome that was predicted - at a high level. The ACC cares about the meaning of what is predicted.
- If the ACC has been convinced that a pain killer placebo has inhibited pain signals, the ACC will stay silent about actual pain that is signalled from interoceptive networks.
- The ACC will signal: physical pain, emotional pain, metaphorical pain, anxiety, disgust, embarrassment, social exclusion especially in adolescence; as one and the same. The ACC's abnormalities being associated with major depression.
- Has a bridging role between the empathetic and self-interested pain monitor. Sapolsky notes the ACC is essential for learning fear and conditioned avoidance by observation alone through an intermediate step of shared representation of self. He concludes "At its core the ACC is about self-interest, with caring about the other person in pain as an add-on."

, amygdala contains > 12 distinct areas: Central, Lateral. It receives simple signals from the lower parts of the brain: pain from the PAG; and abstract complex information from the highest areas: Disgust, heart rate, and suffering from the insula cortex, allowing it to orchestrate emotion. It connects strongly to attention focusing networks. It sends signals to almost every other part of the brain, including to the decision making circuitry of the frontal lobes. It has high levels of D(1) dopamine receptors. During extreme fear the amygdala drives the hippocampus into fear learning. It outputs directly to subcortical reflexive motor pathways when speed is required. Its central nucleus projects to the BNST. It signals the locus ceruleus. It directly signals area 25. The amygdala: - Promotes aggression. Stimulating the amygdala promotes rage. It converts anger into aggression and when impaired it impacts the ability to detect angry facial expressions.
- Participates in disgust
- Perceives fear promoting stimuli, focusing our attention on these. In PTSD sufferers the Amygdala overreacts to mildly fearful stimuli and is slow to calm down and the amygdala expands in size over a period of months. Fear is processed by the lateral nucleus which serves as the input from various senses, and the central nucleus which outputs to the brain stem (central grey - freezing, lateral hypothalamus - blood pressure, activates paraventricular hypothalamus => crf -> hormone adjustments).
- Has lots of receptors for and is highly sensitive to glucocorticoids. Stress inhibits the GABA interneurons in the basolateral amygdala (BLA) allowing the excitatory glutamate releasing neurons to excite more.
- Is sensitive to unsettling/uncertain social situations where it promotes anxiety and makes us distracted. It is also interested in uncertain but potentially painful situations. The amygdala contributes to social and emotional decision making where the BLA supports rejecting an unacceptable offer, as allowed in the Ultimatum Game, by injecting implicit mistrust and vigilance, generating an anger driven rejection that is used as punishment. The amygdala is very rapidly excited by subliminal signals from the thalamus of outgroup skin color. The amygdala subsequently tips social emotions against outgroups unless restrained by the frontal lobe or influenced by subliminal priming to prioritize inclusion. The fast path from the thalamus rapidly but inaccurately signals its identified a weapon.
- Sees suffering of others as increasingly salient with loving-kindness meditation practice, Goleman & Davidson explain.
- Promotes male, but not female, sexual motivation when it is an uncertain potential pleasure.
- Responds to the longing for uncertain potential pleasures and fear that the reward will not be worth it if it happens. The amygdala turns off during orgasm.
- Uses but is not directly involved in vision.
, insula cortex is part of the cerebral cortex folded deep within the lateral sulcus. It includes: anterior, posterior insula; and is overlaid by the operculum. Kandel notes the anterior insula is where feelings are calibrated by evaluating and integrating the importance of the stimuli. It directly signals area 25. LeDoux showed there are two routes for signals of feelings and emotions to the amygdala: a fast unconscious one and a slow one that involves the anterior insula. So the insula is assumed to participate in consciousness where it has been linked to emotion, salience & body homeostasis functions: - Perception,
- Motor control: Hand-&-eye motor movement, Swallowing, Gastric motility, Speech articulation;
- Self-awareness,
- Inter-personal experiences: Disgust at smells, contamination & mutilation which generate visceral responses, that are projected to the amygdala; binding physical and moral aspects of purity (Macbeth effect)
- Suffering of others can be projected by the insula to the amygdala and made increasingly salient with loving-kindness meditation practice, Goleman & Davidson explain.
- Homeostatic regulation of the sympathetic network, parasympathetic network, and immune system. Heart rate and sweat gland activity are monitored. When the amygdala signals concern, the insula prepares the body for action, increasing blood flow to the muscles etc.
; which
generate feelings of pain emerged as a mental experience, Damasio asserts, constructed by the mind using mapping structures and events provided by nervous systems. But feeling pain is supported by older biological functions that support homeostasis. These capabilities reflect the organism's underlying emotive processes that respond to wounds: antibacterial and analgesic chemical deployment, flinching and evading actions; that occur in organisms without nervous systems. Later in evolution, after organisms with nervous systems were able to map non-neural events, the components of this complex response were 'imageable'. Today, a wound induced by an internal disease is reported by old, unmyelinated C nerve fibers. A wound created by an external cut is signalled by evolutionarily recent myelinated fibers that result in a sharp well-localized report, that initially flows to the dorsal root ganglia, then to the spinal cord, where the signals are mixed within the dorsal and ventral horns, and then are transmitted to the brain stem nuclei, thalamus and cerebral cortex. The pain of a cut is located, but it is also felt through an emotive response that stops us in our tracks. Pain amplifies the aggression response of people by interoceptive signalling of brain regions providing social emotions including the PAG projecting to the amygdala; making aggressive people more so and less aggressive people less so. Fear of pain is a significant contributor to female anxiety. Pain is the main reason people visit the ED in the US. Pain is mediated by the thalamus and nucleus accumbens, unless undermined by sleep deprivation. , anger is an emotion which protects a person who has been cheated by a supposed friend. When the exploitation of the altruism is discovered, Steven Pinker explains, the result is a drive for moralistic aggression to hurt the cheater. Anger is mostly experienced as a rapid wave that then quickly dissipates. When it is repressed, for example by a strong moral sense (superego), it can sustain, inducing long term stress. , and disgust is a universal human emotion. Pinker notes it has its own facial expression and is codified in food taboos. The mind must be associated with the proximate environment and parents minimize the risk for their omnivorous children by teaching them what foods to eat and what to avoid. The children's minds are initially receptive to trying all foods but their brains subsequently lock in on the foods they have experienced. These parental choices are affected by schematic influence on what has been beneficial. Adolescent's brain developments undermine these constraints enabling intergroup transfers. Disgust is modulated by the insula cortex which projects signals to the amygdala. Adult humans merge moral and physical disgust enabling metaphorical out grouping. ,

- Feel empathy is the capability to relate to another person from their perspective. It is implemented by spindle neurons. Empathy towards others is controlled by the right-hemisphere supramarginal gyrus. Empathy is context dependently mediated by estrogen. It develops over time: Piaget's preoperational stage includes rudimentary empathy, Theory of mind supports the development; initially feeling someone's pain as one integrated being, then for them and eventually as them. In adults, when someone else is hurt the anterior cingulate cortex, amygdala & insula activates projecting [scapegoating] to the vmPFC. If the pain is physical the PAG activates and motor neurons for the area where the other person was injured. The intertwining of the ACC amygdala & insula in adults results in attribution of fault even when there is none which can make it hard to step in and actually help. But in seven-year-olds the activation is concrete: PAG and sensory & motor cortexes with minimal coupling to the rudimentary vmPFC. In older children the vmPFC is coupled to limbic structures. Ten to twelve year olds abstract empathy to classes of people. Brizendine asserts young girls develop empathy earlier than boys, because their evolved greater neuronal investment in communication and emotion networks. Year old girls are much more responsive to the distress of other people than boys are. At 18 months girls are experiencing infantile puberty. By adolescence the vmPFC is coupled to theory of mind regions and intentional harm induces disgust via the amygdala. Sapolsky explains adolescent boys are utilitarian and tend to accept inequality more than girls do. But both sexes accept inequality as the way it is. Sociopaths do not develop empathy. intensely,

The formation of HL7 messaging communications streams has a relatively high overhead. HL7 version 2 is generally deployed. The version 2 messaging standardizes health care data interchange with messages originally based on character delimited '|' segments (containing character delimited '^' composite fields (containing character delimited '&' subcomponents) in a non XML structure interchanged widely over a secure network stack. The first field in a message segment is the 3 character segment name. HL7 is generally transmitted over MLLP. HL7 v2 has been extended with an XML encoding. HL7 v2 messages have to be augmented to transmit over TCP/IP. The US Government mandate that licenced recipients of HL7 messages understand all aspects of the information transferred. That is point-to-point specific since each sender has their own interpretation of what information goes in what HL7 fields. The usual solution to this situation and rule is (1) an interface engine placed between the two points which maps the sender's information from the fields it uses for transmission to the recipients interpretation of HL7 field usage and (2) a lot of testing to show the mappings are correct and reliable. Because of the impact of changing the interpretation of use of HL7 (on all the interface engines of point connected partners) operational adjustments to HL7 are difficult.

Advocate health illustrates the idea. Robert Pearl notes that the transition is difficult: hospitals that find their efficiency improving should reduce the number of doctors they utilize. But any doctors that are pushed out of the ACO will likely take their patients with them, undermining the revenues that support the FFV business. The ACA regulates qualification to be a Medicare ACO. Individual organizations within a Medicare shared savings ACO continue to submit their own claims and are paid by Medicare for FFS. But the ACO is eligible for shared savings. Within the shared savings program the CMS innovation center has setup advanced payment ACOs. As an alternative to shared savings, in a Pioneer ACO, over time 50% of the FFS payments flow directly to the ACO as a bundled payment. CMS has established quality measures for ACOs for Medicare. The CMS program's purpose is to reward providers for reducing total cost of care for patients through prevention, disease management, and coordination. - CMS initiated its Physician Group Practice Demonstration in 2005. By 2008 the congressional budget office reported on Bonus-eligible organizations.
- CMS defines ACOs as organizations that "create incentives for health care providers to work together to treat an individual patient across care settings - including doctors' offices, hospitals and long-term care facilities."
- CMS has developed APMs which include ACOs, and advanced APMs where the ACOs must be risk bearing.
- CMMI accepts providers' proposals to test various payment systems including shared savings and partial capitation.
- Private market ACOs have formed including: Providence Health & Services, Blue Shield California, Anthem Blue Cross, United Health Care, BCBS Minnesota, BCBS Illinois, Humana, CIGNA, Main Health Management Coalition, BCBS Massachusetts, Aetna.

Brain images of drug-addicted people and obese people have found similar changes in the brain. Obese people's reward network tends to be less responsive to dopamine and have a lower density of dopamine receptors. Obesity spreads like a virus through a social network with a 171% likelihood that a friend of someone who becomes obese will also become so. Obesity is associated with: metabolic syndrome including inflammation, cancer (Aug 2016), high cholesterol, hypertension, type-2-diabetes, asthma and heart disease. It is suspected that this is contributing to the increase in maternal deaths in the US (Sep 2016). Obesity is a complex condition best viewed as representing many different diseases, which is affected by the: Amount of brown adipose tissue (Oct 2016), Asprosin signalling by white adipose tissue (Nov 2016), Genetic alleles including 25 which guarantee an obese outcome, side effects of some pharmaceuticals for: Psychiatric disorders, Diabetes, Seizure, Hypertension, Auto-immunity; Acute diseases: Hypothyroidism, Cushing's syndrome, Hypothalamus disorders; State of the gut microbiome.

- Adverse drug reactions
result from various causes of drug treatments including:
- Individual pharmacogenomics studies how genes affect a person's response to drugs so as to develop personalized drug treatment plans, tailored to a person's specific phenotype. The process optimizes the treatment process but there are barriers to its deployment:
- Large scale clinical trials may test 20,000 individuals, but if a toxic response impacts only 0.1% of them there would only be 20 cases found which is often too few to identify the cause of the response. Instead a process for capturing adverse drug reactions after approval and marketing must be used along with the ability to take a blood sample in these cases.
- Simplified studies on a subset of individuals that have the target allele should be cheaper but are unattractive to pharmaceutical companies which typically want to maximize their target market (Aug 2016).
- F.D.A. has not required genomic testing for most drug developments.
- Health care providers are being slow to use pharmacogenomics. Often third-party payers are unwilling to reimburse the tests.
- Transportation to centralized laboratories for genomic testing causes delays which makes some drug therapy applications impractical. An alternative solution would be to have a patient's EHR contain their genome sequence for immediate genomic implications.

It is supplied with oxygen-rich blood via the hepatic artery and blood rich in semi-processed foodstuffs from the intestines & spleen via the hepatic portal vein. It is constructed from: Hepatocytes which swim in the blood to process it, BECs, Stromal cells, Hepatic stellate cells, Kupffer cells, and blood vessels. The embryonic endoderm cells invade the mesoderm to form the liver bud. Subsequently the liver bud vascularizes and is colonized by hematopoietic cells. The liver operates on a daily cycle (Aug 2018) allowing it time to recover from the stress of processing toxic substances. In a healthy adult liver cells do not divide significantly. But in a damaged liver, the liver cells shift back to a neonatal state to re-enter the cell cycle and rebuild the liver. There are over 100 disorders of the liver. Obesity and diabetes are associated with increased prevalence of these liver disorders worldwide.

There are two structural types: Ischemic and hemorrhagic. Thrombectomy has been found to be a highly effective treatment for some stroke situations (Jan 2018). , CHF is congestive heart failure which occurs when the heart is unable to generate enough blood flow to meet the body's demands. There are two main types: failure due to left ventricular dysfunction and abnormal diastolic function increasing the stiffness of the left ventricle and decreasing its relaxation. Heart expansion in CHF distorts the mitral valve which exacerbates the problems. MitraClip surgery trials found effective in correcting the mitral valve damage (Sep 2018).

The condition is typically chronic and treatment long term (Laguna Honda ward) and is predicted by Stanley Prusiner to become a major burden on the health system. It may be possible to constrain the development some forms of dementia by: physical activity, hypertension management, and ongoing cognitive training.

and type-2-diabetes is the leading cause of blindness, limb amputations and kidney failure. It is a risk factor for Alzheimer's disease. Insulin and glucose levels are regulated by the pancreas, liver, muscle, brain and fat. Diabetes occurs when the insulin level is insufficient to regulate the glucose in the system. As we age our muscles become less sensitive to insulin and the pancreas responds by increasing the amount generated. Increased fat levels in obesity demand more insulin overloading the pancreas. Persistent high glucose levels are also toxic to the pancreas beta cells. High glucocorticoid levels have been associated with type 2 diabetes. There are genetic risk factors since siblings of someone with the disease have three times the baseline risk (about 50% of the risk of getting type 2 diabetes is genetic). The inheritance is polygenic. More than 20 genes have been identified as risk factors, but that is too few to account for the 50% weighting so many more will be identified. Of those identified so far many are associated with the beta cells. The one with the strongest relative risk is TCF7L2. The disease can be effectively controlled through a diligent application of treatments and regular checkups. Doctors are monitored for how under control their patients' diabetes is (Sep 2015). Treatments include: - Metformin - does not change the course of pre-diabetes - if you stop taking it, it is as if it hasn't been taken.

- Affective facial display
is a face expressing strong emotions are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism.
as interpreted by an observer's brain. In:
- Adult observers this activates that amygdala contains > 12 distinct areas: Central, Lateral. It receives simple signals from the lower parts of the brain: pain from the PAG; and abstract complex information from the highest areas: Disgust, heart rate, and suffering from the insula cortex, allowing it to orchestrate emotion. It connects strongly to attention focusing networks. It sends signals to almost every other part of the brain, including to the decision making circuitry of the frontal lobes. It has high levels of D(1) dopamine receptors. During extreme fear the amygdala drives the hippocampus into fear learning. It outputs directly to subcortical reflexive motor pathways when speed is required. Its central nucleus projects to the BNST. It signals the locus ceruleus. It directly signals area 25. The amygdala:
- Promotes aggression. Stimulating the amygdala promotes rage. It converts anger into aggression and when impaired it impacts the ability to detect angry facial expressions.
- Participates in disgust
- Perceives fear promoting stimuli, focusing our attention on these. In PTSD sufferers the Amygdala overreacts to mildly fearful stimuli and is slow to calm down and the amygdala expands in size over a period of months. Fear is processed by the lateral nucleus which serves as the input from various senses, and the central nucleus which outputs to the brain stem (central grey - freezing, lateral hypothalamus - blood pressure, activates paraventricular hypothalamus => crf -> hormone adjustments).
- Has lots of receptors for and is highly sensitive to glucocorticoids. Stress inhibits the GABA interneurons in the basolateral amygdala (BLA) allowing the excitatory glutamate releasing neurons to excite more.
- Is sensitive to unsettling/uncertain social situations where it promotes anxiety and makes us distracted. It is also interested in uncertain but potentially painful situations. The amygdala contributes to social and emotional decision making where the BLA supports rejecting an unacceptable offer, as allowed in the Ultimatum Game, by injecting implicit mistrust and vigilance, generating an anger driven rejection that is used as punishment. The amygdala is very rapidly excited by subliminal signals from the thalamus of outgroup skin color. The amygdala subsequently tips social emotions against outgroups unless restrained by the frontal lobe or influenced by subliminal priming to prioritize inclusion. The fast path from the thalamus rapidly but inaccurately signals its identified a weapon.
- Sees suffering of others as increasingly salient with loving-kindness meditation practice, Goleman & Davidson explain.
- Promotes male, but not female, sexual motivation when it is an uncertain potential pleasure.

mutate p53 is a tumor suppressor which improves the specificity of transcription's DNA binding and promotes the transcriptional activity of E2F. P53's activity is controlled by phosphorylation by cyclin Cdk complexes allowing indirect control of the cell cycle. Among the many genes controlled by p53 are cyclin genes, genes for an inhibitor of cyclin-dependent kinases (Cdk), and the bax gene, which promotes apoptosis. p53 can thus promote cell proliferation. It can drive cells into apoptosis. But it can also stop cell proliferation by arresting the cell cycle. Normally there is a dynamic balance between proliferation of cells and their death. In cancer proliferation may become unregulated due to oncogenic mutations or over expression of key regulatory signalling G proteins such as Ras. Mutations of the p53 suppressor gene are the most frequent suppressor gene mutations in human cancers. Elephants like humans, have a relatively low buildup of cancer with age. Elephant's cells have twenty copies of p53 gene pairs which ensure cells with damaged DNA go into apoptosis blocking cancer onset. P53 has been shown to be involved in irregular brain cell activity in epilepsy and ASD. . They are regularly

- African savanna is the environment where hunter-gatherers is a lifestyle organized around a band of relatives, evolved in humans focused on capturing the cognitive niche in the African savanna. It is of great significance in shaping our minds: behaviors, emotions, creativity, intelligence; and developing survival strategies including use of fire and language, according to evolutionary psychologists. It was practiced by all humans, for most of Homo sapiens existence, until the emergence of farming, and still is by some isolated bands: Ju/'hoansi, New Guinea: Gebusi, Mae Enga; & Borneo head hunters, Maasai & Zulu warriors from Africa, Amazonians: Waorani, Jivaro; Brazilian and Venezuelan Yanomamo. Since the band moves on when it has depleted the resources in an area of land, the soil remains vibrant, but the large animals were typically placed in a position of stress from which they did not recover.

In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy. enabling

- Age-related memory loss,
also called benign senescent forgetfulness, is a different
condition from Alzheimer's
disease is a dementia which correlates with deposition of amyloid plaques in the neurons. As of 2015 there are 5 million Alzheimer's patients in the USA. It was originally defined as starting in middle age which is rare, so it was a rare dementia. But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI). Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged. The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease. Grid cell destruction results in a sense of being lost. The default mode network is disrupted. Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes. There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016). The Alzheimer's pathway follows:
- Plaques form. These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes. APP deployed in the cell membrane is cut into three parts. The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough.
- Solanezumab aimed to inhibit plaque formation but clinical trials failed (Nov 2016).
- Encouraging the garbage collection of amyloid and tau with gamma rhythms stimulation retards Alzheimer's in mice studies (Mar 2019)
- BACE inhibitors block an enzyme needed to form amyloid.
- Mutation driven misfolded Tau proteins can form tangles within the cytoplasm of neurons. The Tau tangles kill nerve cells. LMTX is a drug treatment targeted at these tangles.
- The brain becomes inflamed resulting in the killing of many more nerve cells. The hippocampus disintegrates and the brain loses critical functions and memory loss becomes noticeable.

the adaptive in evolutionary biology is a trait that increased the number of surviving offspring in an organism's ancestral lineage. Holland argues: complex adaptive systems (CAS) adapt due to the influence of schematic strings on agents. Evolution indicates fitness when an organism survives and reproduces. For his genetic algorithm, Holland separated the adaptive process into credit assignment and rule discovery. He assigned a strength to each of the rules (alternate hypothesis) used by his artificial agents, by credit assignment - each accepted message being paid for by the recipient, increasing the sender agent's rule's strength (implicit modeling) and reducing the recipient's. When an agent achieved an explicit goal they obtained a final reward. Rule discovery used the genetic algorithm to select strong rule schemas from a pair of agents to be included in the next generation, with crossing over and mutation applied, and the resulting schematic strategies used to replace weaker schemas. The crossing over genetic operator is unlikely to break up a short schematic sequence that provides a building block retained because of its 'fitness'; In Deacon's conception of evolution, an adaptation is the realization of a set of constraints on candidate mechanisms, and so long as these constraints are maintained, other features are arbitrary.

disease caused by the HIV is human immunodeficiency virus, an RNA retrovirus which causes AIDS. It infects T-lymphocytes helper cells slowly destroying the host's immune system. The main pandemic form of HIV is HIV-1 M which has been traced back to a spillover to Cameroon/Congolese forest Chimpanzees of SIVs that weakly infected proximate humans and then was amplified by social conditions in expanding towns: Ouesso, Brazzaville, Leopoldville; down river from these forests during the 1900 - 1920s. Additional amplification occurred through public health programs: Trypanosomiasis, STDs; which cross-infected subpopulations of Leopoldville/Kinshasa around the same time. UNESCO organized Haitian support for the DRC in the 1960s vectored HIV-1 M back to Haiti where the blood plasma trade provided an evolved amplifier for HIV-1 M infected plasma to flow into the US healthcare supply chain through Miami. Some HIV's enter the lymphocytes by leveraging the T cells CCR5 protein. The HIV X4 variant leverages CXCR4.

also amplifies the threat of tuberculosis, consumption or otherwise TB, is mostly an airborn bacterial lung infection, but it can also infect the brain, kidneys and other parts of the body. The only vaccine is still the BCG. The deployment of antibiotics during the 1940s allowed effective treatment: Streptomycin. In 1963 epidemiologist George Comstock realized why 30% of Alaskan adults were infected with TB - it grows slowly and is transmitted to other people before symptoms occur. Treatment was expanded to all contacts of a person with symptoms, who tested positive for TB. This strategy eradicated TB in the West, but was considered impractical in poor countries. Diagnostic tools for TB are insufficient. And because TB grows slowly in walled off pockets in the lungs it takes many months of treatment for antibiotics to eradicate the infection. TB benefits from compromised hosts and has benefited from HIV/AIDS. TB is also leveraging the plasmids that now carry immunity to all current antibiotics. In 2016 it is estimated to latently infect two billion people. 9.6 million worldwide became infected in 2014. 1.5 million people will die from TB in 2016. Deaths from the disease have fallen drastically since 2000. TB has been halted or reversed in 16 of the 22 countries: India (Sep 2016, Infection base estimate increased Oct 2016), Vietnam, Indonesia; that have the majority of cases. But it is still the infectious disease causing the most deaths world-wide. In 2018 W.H.O. asserts there is a $3.5 billion shortfall in funding for TB public health control efforts, a gap that will double by 2023. Nano scale drug delivery has the potential to push back on TB and is being actively researched (May 2016). .

of the immune system has to support and protect an inventory of host cell types, detect and respond to invaders and maintain the symbiont equilibrium within the microbiome. It detects microbes which have breached the secreted mucus barrier, driving them back and fortifying the barrier. It culls species within the microbiome that are expanding beyond requirements. It destroys invaders who make it into the internal transport networks. As part of its initialization it has immune cells which suppress the main system to allow the microbiome to bootstrap. The initial microbiome is tailored by the antibodies supplied from the mother's milk while breastfeeding. The immune system consists of two main parts the older non-adaptive part and the newer adaptive part. The adaptive part achieves this property by being schematically specified by DNA which is highly variable. By rapid reproduction the system recombines the DNA variable regions in vast numbers of offspring cells which once they have been shown not to attack the host cell lines are used as templates for interacting with any foreign body (antigen). When the immune cell's DNA hyper-variable regions are expressed as y-shaped antibody proteins they typically include some receptor like structures which match the surfaces of the typical antigen. Once the antibody becomes bound to the antigen the immune system cells can destroy the invader. , it can now be

treatment with recombinant DNA (DNA), a polymer composed of a chain of deoxy ribose sugars with purine or pyrimidine side chains. DNA naturally forms into helical pairs with the side chains stacked in the center of the helix. It is a natural form of schematic string. The purines and pyrimidines couple so that AT and GC pairs make up the stackable items. A code of triplets of base pairs (enabling 64 separate items to be named) has evolved which now redundantly represents each of the 20 amino-acids that are deployed into proteins, along with triplets representing the termination sequence. Chemical modifications and histone binding (chromatin) allow cells to represent state directly on the DNA schema. To cope with inconsistencies in the cell wide state second messenger and evolved amplification strategies are used. to

David Quammen explains the four key challenges of viruses: Getting from one host to another, penetrating a cell within the host, commandeering the cell's infrastructure, escaping from the cell and organism; Single-stranded RNA viruses: Coronavirus, chickungunya, dengue, Ebola, Hantas, Hendra, Influenzas, Junin, Lassa, Machupo, Marburg, Measles, Mumps, Nipah, Rabies, Retrovirus (HIV), Rhinovirus, yellow fever; are subject to more mutation events than DNA viruses, but limits the size of the genetic string. Double stranded DNA viruses: baculoviruses, hepadnaviruses, Herpesviruses, iridoviruses, papillomavirses, poxviruses; can leverage relatively far larger genetic payloads. The relationship with the reservoir host is long-term, a parasitic or symbiotic relationship, developing over millions of years. But opportunistically, it may spillover into a secondary host, with the virus entering the host cell, leveraging the host infrastructure to replicate its self massively and then exiting the host cell by rupturing it and killing the organism. .

gene. It is a major constituent of Parkinson's disease corresponds to the breakdown of certain interneurons in the brain. It is not fully understood why this occurs. Dopamine system neuron breakdown generates the classical symptoms of tremors and rigidity. In some instances an uncommon LRRK2 gene mutation confers a high risk of Parkinson's disease. In rare cases Italian and Greek families are impacted in their early forties and fifties resulting from a single letter mutation in alpha-synuclein which alters the alpha-synuclein protein causing degeneration in the substantia nigra, after a build up of Lewy bodies in the neurons. But poisoning from MPTP has also been shown to destroy dopamine system neurons. DeLong showed that MPTP poisoning results in overactivity in the subthalamic nucleus. People who have an appendectomy in their 20s are at lower risk of developing Parkinson's disease. The Alpha-synuclein protein is known to build up in the appendix in association with changes in the gut microbiome. This buildup may support the 'flow' of alpha-synuclein from the gut along neurons that route to the brain. Paraquat has also been linked to Parkinson's disease. Parkinson's disease does not directly kill many sufferers. But it impacts swallowing which encourages development of pneumonia through inhaling or aspirating food. And it undermines balance which can increase the possibility of falls. Dememtia can also develop. Treatment with deep-brain stimulation, after surgical implantation of electrodes in the subthalamic nucleus removes the symptoms of Parkinson's disease in some patients. Lewy bodies are protein clumps that are a pathological mark of Parkinson's disease and Lewy body dementia. A major component of the clumps is alpha-synuclein. . Knockout

relaxation, long distance signalling, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy.

As of 2015 there are 5 million Alzheimer's patients in the USA is the United States of America. . It was originally defined as
starting in middle age which is rare, so it was a rare
dementia. But in 1980s it was redefined as any
dementia without another known cause. Early indications
include mood and behavioral changes (MBI is mild behavioral impairment, a proposed early diagnosis for dementia. It recognizes and measures something that some experts say is often overlooked: Sharp changes in mood and behavior can precede the memory and thinking problems of dementia. But there is a risk of over diagnosis which could leave many people unnecessarily fearful about their futures and seeking more tests. And the diagnosis could affect insurance premiums. To imply MBI the symptoms must last for more than six months and be a fundamental change in behavior. )
and declarative memory , or explicit memory, allows higher animals to consciously remember people, places and objects. It includes episodic and semantic memory. It is supported by the medial region of the temporal lobe, explains Kandel.
and thinking problems (MCI is mild cognitive impairment, a sense of memory loss despite normal performance on memory tests. It is often associated with Alzheimer's disease. ).
Specific cells within the hippocampal is a part of the medial temporal lobe of the brain involved in the temporary storage or coding of long-term episodic memory. It includes the dentate gyrus. Memory formation in the cells of the hippocampus uses the MAP kinase signalling network which is impacted by sleep deprivation. The hippocampus dependent memory system is directly affected by cholinergic changes throughout the wake-sleep cycle. Increased acetylcholine during REM sleep promotes information attained during wakefulness to be stored in the hippocampus by suppressing previous excitatory connections while facilitating encoding without interference from previously stored information. During slow-wave sleep low levels of acetylcholine cause the release of the suppression and allow for spontaneous recovery of hippocampal neurons resulting in memory consolidation. It was initially associated with memory formation by McGill University's Dr. Brenda Milner, via studies of 'HM' Henry Molaison, whose medial temporal lobes had been surgically destroyed leaving him unable to create new explicit memories. The size of neurons' dendritic trees expands and contracts over a female rat's ovulatory cycle, with the peak in size and cognitive skills at the estrogen high point. Adult neurogenesis occurs in the hippocampus (3% of neurons are replaced each month) where the new neurons integrate into preexisting circuits. It is enhanced by learning, exercise, estrogen, antidepressants, environmental enrichment, and brain injury and inhibited by various stressors explains Sapolsky. Prolonged stress makes the hippocampus atrophy. He notes the new neurons are essential for integrating new information into preexisting schemas -- learning that two things you thought were the same are actually different. Specific cells within the hippocampus and its gateway, the entorhinal cortex, are compromised by Alzheimer's disease. It directly signals area 25.
circuitry and its gateway, the entorhinal cortex is a main limbic association area between the hippocampus and the neocortex, in the medial temporal lobe. It is a hub for memory and navigation: location awareness is supported by grid cells. It is the first brain area impacted in Alzheimer's disease. , are
damaged. The amygdala contains > 12 distinct areas: Central, Lateral. It receives simple signals from the lower parts of the brain: pain from the PAG; and abstract complex information from the highest areas: Disgust, heart rate, and suffering from the insula cortex, allowing it to orchestrate emotion. It connects strongly to attention focusing networks. It sends signals to almost every other part of the brain, including to the decision making circuitry of the frontal lobes. It has high levels of D(1) dopamine receptors. During extreme fear the amygdala drives the hippocampus into fear learning. It outputs directly to subcortical reflexive motor pathways when speed is required. Its central nucleus projects to the BNST. It signals the locus ceruleus. It directly signals area 25. The amygdala: - Promotes aggression. Stimulating the amygdala promotes rage. It converts anger into aggression and when impaired it impacts the ability to detect angry facial expressions.
- Participates in disgust
- Perceives fear promoting stimuli, focusing our attention on these. In PTSD sufferers the Amygdala overreacts to mildly fearful stimuli and is slow to calm down and the amygdala expands in size over a period of months. Fear is processed by the lateral nucleus which serves as the input from various senses, and the central nucleus which outputs to the brain stem (central grey - freezing, lateral hypothalamus - blood pressure, activates paraventricular hypothalamus => crf -> hormone adjustments).
- Has lots of receptors for and is highly sensitive to glucocorticoids. Stress inhibits the GABA interneurons in the basolateral amygdala (BLA) allowing the excitatory glutamate releasing neurons to excite more.
- Is sensitive to unsettling/uncertain social situations where it promotes anxiety and makes us distracted. It is also interested in uncertain but potentially painful situations. The amygdala contributes to social and emotional decision making where the BLA supports rejecting an unacceptable offer, as allowed in the Ultimatum Game, by injecting implicit mistrust and vigilance, generating an anger driven rejection that is used as punishment. The amygdala is very rapidly excited by subliminal signals from the thalamus of outgroup skin color. The amygdala subsequently tips social emotions against outgroups unless restrained by the frontal lobe or influenced by subliminal priming to prioritize inclusion. The fast path from the thalamus rapidly but inaccurately signals its identified a weapon.

- Uses but is not directly involved in vision.
, cerebelum is involved with the efficiency of fine movement. It modulates the force and range of motion and is involved in motor coordination and the learning of motor skills. Damage to the cerebellum impairs standing, walking, or performance of coordinated movements. A virtuoso pianist or other performing musician depends on their cerebellum. The cerebellum receives visual, auditory, vestibular, and somatosensory information. It also receives information about individual muscular movements being directed by the brain. The cerebellum integrates this information and modifies the motor outflow, exerting a coordinating and smoothing effect on the movements. However, patients born without a cerebellum have survived reasonably well. The cerebellum is part of the implicit learning mechanism. It is required for the rabbit eye-blink to be classically conditioned to respond to a sound, and puff of air (threat to eye). It integrates the sound and puff and outputs the response to the motor area (blink). Levitin has shown the cerebellum participates in aspects of emotion and auditory processing. He found the cerebellum and basal ganglia were active throughout a session listening to music, modeling the beat, rewarding a match between the internal and external rhythm and integrating movement. And he notes the cerebellum providing Williams syndrome sufferers with their capability to play music. and other areas
supporting implicit memory is an unconscious form of memory where previous experiences aid the learning activity, as illustrated by subliminal priming. This conditioning uses implicit memory to associate prior experience and future predictions with current stimuli. Kandel showed that this implicit associative learning occurs in Aplysia's simple defensive reflex neural circuit. Implicit memory is often maintained into old age, including in the early stages of Alzheimer's disease. Implicit memory depends on regions of the brain that respond to stimuli: amygdala, cerebellum, basal ganglia; and reflex pathways. Implicit facial memory is supported by the fusiform gyrus and is consolidated during REM sleep.

with risk factors - ApoE4 is a gene variant which produces the E4 variant of APOE. It is a risk-factor for late-onset sporadic Alzheimer's disease. Being homozygote for E4 does not imply getting Alzheimer's but does increase the risk 20 fold. ApoE2 may reduce the risk of Alzheimer's. It appears that ApoE4 differentially affects women. Apoe4 is known to be broken down into fragments which impare mitochondrial operation. It also promotes amyloid plaque buildup. Therapies are being developed based on small molecules which reshape ApoE4 to be more like ApoE3 reducing the breakdown. for late

2015), type 2 diabetes is the leading cause of blindness, limb amputations and kidney failure. It is a risk factor for Alzheimer's disease. Insulin and glucose levels are regulated by the pancreas, liver, muscle, brain and fat. Diabetes occurs when the insulin level is insufficient to regulate the glucose in the system. As we age our muscles become less sensitive to insulin and the pancreas responds by increasing the amount generated. Increased fat levels in obesity demand more insulin overloading the pancreas. Persistent high glucose levels are also toxic to the pancreas beta cells. High glucocorticoid levels have been associated with type 2 diabetes. There are genetic risk factors since siblings of someone with the disease have three times the baseline risk (about 50% of the risk of getting type 2 diabetes is genetic). The inheritance is polygenic. More than 20 genes have been identified as risk factors, but that is too few to account for the 50% weighting so many more will be identified. Of those identified so far many are associated with the beta cells. The one with the strongest relative risk is TCF7L2. The disease can be effectively controlled through a diligent application of treatments and regular checkups. Doctors are monitored for how under control their patients' diabetes is (Sep 2015). Treatments include: - Metformin - does not change the course of pre-diabetes - if you stop taking it, it is as if it hasn't been taken.

the capacity of mitochondria are the energy molecule generating production functions of eukaryotic cells. They are vestigial blue-green bacteria with their own DNA and infrastructure. Unlike stand-alone bacteria they also use the eukaryotic host DNA and infrastructure for some functions. The high energy molecules are nucleotides with a high energy phosphate bond. The most used high energy molecule is Adenosine-tri-phosphate.
to support neuron, specialized eukaryotic cells include channels which control flows of sodium and potassium ions across the massively extended cell membrane supporting an electro-chemical wave which is then converted into an outgoing chemical signal transmission from synapses which target nearby neuron or muscle cell receptors. Neurons are supported by glial cells. Neurons include a: - Receptive element - dendrites
- Transmitting element - axon and synaptic terminals. The axon may be myelinated, focusing the signals through synaptic transmission, or unmyelinated - where crosstalk is leveraged.
- Highly variable DNA schema using transposons.

Neurons of sporadic Alzheimer's sufferers show greater APP is Amyloid Precursor Protein. It is encoded by the gene presenilin. gene diversity due to somatic recombination alters the DNA of somatic cells: Immunoglobulin class switching, B cell receptor gene assembly and T-cell receptor gene V(D)J recombination, neuron genes that encode APP, reused in carcinogenesis; and is inherited by daughter cells. ;
It may be initiated by: stress is a multi-faceted condition reflecting high cortisol levels. Dr. Robert Sapolsky's studies of baboons indicate that stress helps build readiness for fight or flight. As these actions occur the levels of cortisol return to the baseline rate. A stressor is anything that disrupts the regular homeostatic balance. The stress response is the array of neural and endocrine changes that occur to respond effectively to the crisis and reestablish homeostasis. - The short term response to the stressor
- activates the amygdala which: Stimulates the brain stem resulting in inhibition of the parasympathetic nervous system and activation of the sympathetic nervous system with the hormones epinephrine and norepinephrine deployed around the body, Activates the PVN which generates a cascade resulting in glucocorticoid secretion to: get energy to the muscles with increased blood pressure for a powerful response. The brain's acuity and cognition are stimulated. The immune system is stimulated with beta-endorphin and repair activities curtail. In order for the body to destroy bacteria in wounds, pro-inflammatory cytokines increase blood flow to the area. The induced inflammation signals the brain to activate the insula and through it the ACC. But when the stressor is
- long term: loneliness, debt; and no action is necessary, or possible, long term damage ensues. Damage from such stress may only occur in specific situations: Nuclear families coping with parents moving in. Sustained stress provides an evolved amplifier of a position of dominance and status. It is a strategy in female aggression used to limit reproductive competition. Sustained stress:
- Stops the frontal cortex from ensuring we do the harder thing, instead substituting amplification of the individual's propensity for risk-taking and impairing risk assessment!
- Activates the integration between the thalamus and amygdala.
- Acts differently on the amygdala in comparison to the frontal cortex and hippocampus: Stress strengthens the integration between the Amygdala and the hippocampus, making the hippocampus fearful.
- BLA & BNST respond with increased BDNF levels and expanded dendrites persistently increasing anxiety and fear conditioning.
- Makes it easier to learn a fear association and to consolidate it into long-term memory. Sustained stress makes it harder to unlearn fear by making the prefrontal cortex inhibit the BLA from learning to break the fear association and weakening the prefrontal cortex's hold over the amygdala. And glucocorticoids decrease activation of the medial prefrontal cortex during processing of emotional faces. Accuracy of assessing emotions from faces suffers. A terrified rat generating lots of glucocorticoids will cause dendrites in the hippocampus to atrophy but when it generates the same amount from excitement of running on a wheel the dendrites expand. The activation of the amygdala seems to determine how the hippocampus responds.
- Depletes the nucleus accumbens of dopamine biasing rats toward social subordination and biasing humans toward depression.
- Disrupts working memory by amplifying norepinephrine signalling in the prefrontal cortex and amygdala to prefrontal cortex signalling until they become destructive. It also desynchronizes activation in different frontal lobe regions impacting shifting of attention.
- Increases the risk of autoimmune disease (Jan 2017)
- During depression, stress inhibits dopamine signalling.

It detects microbes which have breached the secreted mucus barrier, driving them back and fortifying the barrier. It culls species within the microbiome that are expanding beyond requirements. It destroys invaders who make it into the internal transport networks. As part of its initialization it has immune cells which suppress the main system to allow the microbiome to bootstrap. The initial microbiome is tailored by the antibodies supplied from the mother's milk while breastfeeding. The immune system consists of two main parts the older non-adaptive part and the newer adaptive part. The adaptive part achieves this property by being schematically specified by DNA which is highly variable. By rapid reproduction the system recombines the DNA variable regions in vast numbers of offspring cells which once they have been shown not to attack the host cell lines are used as templates for interacting with any foreign body (antigen). When the immune cell's DNA hyper-variable regions are expressed as y-shaped antibody proteins they typically include some receptor like structures which match the surfaces of the typical antigen. Once the antibody becomes bound to the antigen the immune system cells can destroy the invader. to the

AMCs offer researchers clinical research support: Virus is a relatively small capsule containing genetic material: RNA, DNA; which utilizes the cellular infrastructure of its target host to replicate its genetic material and operational proteins. David Quammen explains the four key challenges of viruses: Getting from one host to another, penetrating a cell within the host, commandeering the cell's infrastructure, escaping from the cell and organism; Single-stranded RNA viruses: Coronavirus, chickungunya, dengue, Ebola, Hantas, Hendra, Influenzas, Junin, Lassa, Machupo, Marburg, Measles, Mumps, Nipah, Rabies, Retrovirus (HIV), Rhinovirus, yellow fever; are subject to more mutation events than DNA viruses, but limits the size of the genetic string. Double stranded DNA viruses: baculoviruses, hepadnaviruses, Herpesviruses, iridoviruses, papillomavirses, poxviruses; can leverage relatively far larger genetic payloads. The relationship with the reservoir host is long-term, a parasitic or symbiotic relationship, developing over millions of years. But opportunistically, it may spillover into a secondary host, with the virus entering the host cell, leveraging the host infrastructure to replicate its self massively and then exiting the host cell by rupturing it and killing the organism.

dry form is the slow destruction of foveal vision. It is caused by a buildup of drusen pigments due to a failure of the aging cellular infrastructure to remove these metabolic waste products. The pigments inhibit the flow of oxygen from the choroid blood supply through Bruch's membrane to the RPE and photo-receptor cells. The drusen damage the RPE causing this layer of the macular to thin. Over a decade this results in deterioration of perception in the fovea. In about 20% of sufferers the reduced flows across the RPE result in development of more blood vessels which anomalously push through Bruch's membrane causing the far more rapidly destructive wet macular degeneration. Dry macular degeneration can be detected using an Amsler grid and confirmed with OCT. and
additionally, blood vessels in the wet form is an age related, rapidly irreversible, destruction of foveal vision. It occurs in 20% of AMD and can damage the retina within a 12 month period. It is due to aberrant blood vessel development in the choroid, pushing through the RPE and disrupting it. Treatments using locally deployed VEGF and POGF receptor blockers inhibit the problematic angiogenesis. . It

By leveraging the clustering of SNPs in neighborhoods of the genes and knowledge of the boundaries of the neighborhoods you can identify all the SNPs without spending huge amounts of money or laboratory time to test for every one. HapMap was designed to define the boundaries of the neighborhoods to allow these shortcuts in genome analysis reducing the amount of work by a factor of 40. data it was realized

Brain images of drug-addicted people and obese people have found similar changes in the brain. Obese people's reward network tends to be less responsive to dopamine and have a lower density of dopamine receptors. Obesity spreads like a virus through a social network with a 171% likelihood that a friend of someone who becomes obese will also become so. Obesity is associated with: metabolic syndrome including inflammation, cancer (Aug 2016), high cholesterol, hypertension, type-2-diabetes, asthma and heart disease.

mapping of DNA (DNA), a polymer composed of a chain of deoxy ribose sugars with purine or pyrimidine side chains. DNA naturally forms into helical pairs with the side chains stacked in the center of the helix. It is a natural form of schematic string. The purines and pyrimidines couple so that AT and GC pairs make up the stackable items. A code of triplets of base pairs (enabling 64 separate items to be named) has evolved which now redundantly represents each of the 20 amino-acids that are deployed into proteins, along with triplets representing the termination sequence. Chemical modifications and histone binding (chromatin) allow cells to represent state directly on the DNA schema. To cope with inconsistencies in the cell wide state second messenger and evolved amplification strategies are used. base, a nucleotide base is the side chain purine (A or G) or pyrimidine (T or C). A is a natural pair for T. G pairs naturally with C. These bases have multiple uses in cells including energy transfer, second messenger signalling as well as genetic data storage, transcription and translation. Deacon argues that the multiple uses are significant to the emergence of evolution.

CAS theory views cultures as operating via memetic schemata evolved by memetic operators to support a cultural superorganism. Evolutionary psychology asserts that human culture reflects adaptations generated while hunting and gathering. Dehaene views culture as essentially human, shaped by exaptations and reading, transmitted with support of the neuronal workspace and stabilized by neuronal recycling. Damasio notes prokaryotes and social insects have developed cultural social behaviors. Sapolsky argues that parents must show children how to transform their genetically derived capabilities into a culturally effective toolset. He is interested in the broad differences across cultures of: Life expectancy, GDP, Death in childbirth, Violence, Chronic bullying, Gender equality, Happiness, Response to cheating, Individualist or collectivist, Enforcing honor, Approach to hierarchy; illustrating how different a person's life will be depending on the culture where they are raised. Culture:
- Is deployed during pregnancy & childhood, with parental mediation. Nutrients, immune messages and hormones all affect the prenatal brain. Hormones: Testosterone with anti-Mullerian hormone masculinizes the brain by entering target cells and after conversion to estrogen binding to intracellular estrogen receptors; have organizational effects producing lifelong changes. Parenting style typically produces adults who adopt the same approach. And mothering style can alter gene regulation in the fetus in ways that transfer epigenetically to future generations! PMS symptoms vary by culture.
- Is also significantly transmitted to children by their peers during play. So parents try to control their children's peer group.
- Is transmitted to children by their neighborhoods, tribes, nations etc.
- Influences the parenting style that is considered appropriate.
- Can transform dominance into honor. There are ecological correlates of adopting honor cultures. Parents in honor cultures are typically authoritarian.
- Is strongly adapted across a meta-ethnic frontier according to Turchin.

- Can provide varying levels of support for innovation. Damasio suggests culture is influenced by feelings:
- As motives for intellectual creation: prompting
detection and diagnosis of homeostatic
deficiencies, identifying
desirable states worthy of creative effort.
- As monitors of the success and failure of cultural
instruments and practices
- As participants in the negotiation of adjustments

- An emotional are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism.

- Amygdala
contains > 12 distinct areas: Central is a relatively ancient evolved part of the amygdala which processes 'innate' fears. It projects to the BNST to raise the heart rate and blood pressure in preparation for fight and flight.
, Lateral is the basolateral amygdala, a relatively recently evolved part of the amygdala which learns stimuli to fear and then signals the central amygdala. It recieves inputs from all sensory networks. Some are fast pathways that allow the BLA to detect and respond when the sensory cortex is unaware. But it is far less accurate than the cortex. The BLA's learning involves increased excitability of synapses coupling the BLA and central amygdala. This is due to gene driven: Increased levels of growth factors promoting new connections, more receptors for excitatory neurotransmitters in dendritic spines. The BLA also responds to signals from the frontal cortex that a stimulus no longer appears frightening. This subset of BLA cells respond inhibiting the associating subset. Stress and glucocorticoids increase levels of CRH and BDNF encouraging the building of new dendrites and synapses. . It receives simple
signals from the lower parts of the brain: pain emerged as a mental experience, Damasio asserts, constructed by the mind using mapping structures and events provided by nervous systems. But feeling pain is supported by older biological functions that support homeostasis. These capabilities reflect the organism's underlying emotive processes that respond to wounds: antibacterial and analgesic chemical deployment, flinching and evading actions; that occur in organisms without nervous systems. Later in evolution, after organisms with nervous systems were able to map non-neural events, the components of this complex response were 'imageable'. Today, a wound induced by an internal disease is reported by old, unmyelinated C nerve fibers. A wound created by an external cut is signalled by evolutionarily recent myelinated fibers that result in a sharp well-localized report, that initially flows to the dorsal root ganglia, then to the spinal cord, where the signals are mixed within the dorsal and ventral horns, and then are transmitted to the brain stem nuclei, thalamus and cerebral cortex. The pain of a cut is located, but it is also felt through an emotive response that stops us in our tracks. Pain amplifies the aggression response of people by interoceptive signalling of brain regions providing social emotions including the PAG projecting to the amygdala; making aggressive people more so and less aggressive people less so. Fear of pain is a significant contributor to female anxiety. Pain is the main reason people visit the ED in the US. Pain is mediated by the thalamus and nucleus accumbens, unless undermined by sleep deprivation. from the PAG is periaqueductal gray, an ancient core brain structure that projects pain sensations to the amygdala, has a high density of vasopressin and oxytocin receptors and a direct connection to the orbitofrontal cortex, potentially supporting maternal love. It has a critical role in autonomic function, motivated behavior and responses to threats - the dorsal PAG activates during defensive behaviors: freezing immobility, running, jumping, increased blood pressure; while caudal ventrolateral PAG activation results in an immobile relaxed posture. The PAG's enkephalin-producing cells suppress pain. ;
and abstract complex information from the highest areas: Disgust is a universal human emotion. Pinker notes it has its own facial expression and is codified in food taboos. The mind must be associated with the proximate environment and parents minimize the risk for their omnivorous children by teaching them what foods to eat and what to avoid. The children's minds are initially receptive to trying all foods but their brains subsequently lock in on the foods they have experienced. These parental choices are affected by schematic influence on what has been beneficial. Adolescent's brain developments undermine these constraints enabling intergroup transfers. Disgust is modulated by the insula cortex which projects signals to the amygdala. Adult humans merge moral and physical disgust enabling metaphorical out grouping. , heart rate, and suffering
from the insula cortex is part of the cerebral cortex folded deep within the lateral sulcus. It includes: anterior, posterior insula; and is overlaid by the operculum. Kandel notes the anterior insula is where feelings are calibrated by evaluating and integrating the importance of the stimuli. It directly signals area 25. LeDoux showed there are two routes for signals of feelings and emotions to the amygdala: a fast unconscious one and a slow one that involves the anterior insula. So the insula is assumed to participate in consciousness where it has been linked to emotion, salience & body homeostasis functions: - Perception,
- Motor control: Hand-&-eye motor movement, Swallowing, Gastric motility, Speech articulation;
- Self-awareness,
- Inter-personal experiences: Disgust at smells, contamination & mutilation which generate visceral responses, that are projected to the amygdala; binding physical and moral aspects of purity (Macbeth effect)
- Suffering of others can be projected by the insula to the amygdala and made increasingly salient with loving-kindness meditation practice, Goleman & Davidson explain.
- Homeostatic regulation of the sympathetic network, parasympathetic network, and immune system. Heart rate and sweat gland activity are monitored. When the amygdala signals concern, the insula prepares the body for action, increasing blood flow to the muscles etc.

other part of the brain, including to the decision making integrates situational context, state and signals to prioritize among strategies and respond in a timely manner. It occurs in all animals, including us and our organizations: - Individual human decision making includes conscious and unconscious aspects. Situational context is highly influential: supplying meaning to our general mechanisms, & for robots too. Emotions are important in providing a balanced judgement. The adaptive unconscious interprets percepts quickly supporting 'fast' decision making. Conscious decision making, supported by the: DLPFC, vmPFC and limbic system; can use slower autonomy. The amygdala, during unsettling or uncertain social situations, signals the decision making regions of the frontal lobe, including the orbitofrontal cortex. The BLA supports rejecting unacceptable offers. Moral decisions are influenced by a moral decision switch. Sleeping before making an important decision is useful in obtaining the support of the unconscious in developing a preference. Word framing demonstrates the limitations of our fast intuitive decision making processes. And prior positive associations detected by the hippocampus, can be reactivated with the support of the striatum linking it to the memory of a reward, inducing a bias into our choices. Prior to the development of the PFC, the ventral striatum supports adolescent decision making. Neurons involved in decision making in the association areas of the cortex are active for much longer than neurons participating in the sensory areas of the cortex. This allows them to link perceptions with a provisional action plan. Association neurons can track probabilities connected to a choice. As evidence is accumulated and a threshold is reached a choice is made, making fast thinking highly adaptive. Diseases including: schizophrenia and anorexia; highlight aspects of human decision making.

circuitry
of the frontal lobes of the cerebral cortex is at the front of the brain. It includes the: prefrontal cortex, motor cortex. Sapolsky asserts it makes you do the harder thing when it's the right thing to do. The frontal cortex supports working memory to sustain focus on a task. It also coordinates the strategic actions necessary to achieve success. It provides impulse control, regulation of emotion, and willpower. The prefrontal cortex maintains focus by deprioritizing currently irrelevant streams of information. The frontal cortex tracks rules. Over a lifetime, that builds into a costly activity. Once it tires, responses become less prosocial. But practice shifts operation of tasks to the cerebellum. The frontal cortex signals the tegmentum and accumbens with the conclusions of its expectancy/discrepancy calculations. The frontal lobe provides executive function, considering bits of information, assessing patterns and then prioritizing the strategies. The frontal lobe is the most recent part of the brain to evolve and involves a disproportionate percentage of primate-unique genes in its development and operation. It does not complete development until the mid-20s. It includes spindle neurons. It is easily damaged. Sapolsky (Nauta) notes that its ventromedial prefrontal cortex is a quasi-member of the limbic system. .
It has high levels of D(1) dopamine is a synaptic signal supporting generalized goal-directed behavior & anticipation of reward. Its significance is that the receptors that detect the signal are of the slow acting type and are used to alter (modulate) the response of fast acting dopaminergic neural circuits in which the receptors are deployed (LTP). The signal detects significant changes including predictions of models and actual results which differ unexpectedly. Dopamine is released primarily by neurons of the ventral tegmental area and the substantia nigra. The dopamine network architecture is designed to signal the possibility of any type of reward: Norm violation punishment, Winning a lottery, & Misfortune of an envied competitor. Dopamine signalling: - Rescales continuously to accommodate the range of intensity offered by different stimuli. So dopamine's responses to any reward habituate. GABA is released by some tegmental neurons to induce habituation. This allows addictions to develop.
- Reflects the anticipation of reward. It supports establishment of a relationship between a signal, working for a reward and obtaining the reward, but subsequently dopamine is mainly released encouraging the work, right after the signal supporting anticipation of the reward. Anticipation requires learning and is reflected in hippocampus activity. That explains context dependent cravings. And the learning architecture means reliable cues become rewarding. The accumbens supports willpower. And dopamine
- Promotes goal-oriented behavior needed to obtain & likely to achieve the reward - through the dopamine projections to the prefrontal cortex. That makes dopamine central to:
- Motivation. This binding fails in depression - due to stress and in anxiety - due to signals from the amygdala.
- The prefrontal cortex's mesocortically stimulated support for willpower to act to delay rewards. To sustain work for delayed rewards additional dopamine is released based on the length of the delay and the rewards uncertainty (modelled in the dorsolateral prefrontal cortex - which promotes the long term and the ventromedial prefrontal cortex - which promotes the short term) and the anticipated size of the reward (modelled in the accumbens). Impulsiveness in ADHD is reflected in abnormal dopamine processing. Addictive drugs bias the dopamine network towards impulsiveness.
- Is lowered by certain gene variants which induce: less dopamine in the synapse, fewer receptors, lower responsiveness of receptors; associated with (as tiny effects in hugely varying social scenarios): sensation seeking, risk taking, attentional problems, extroversion; where:
- The receptor D4's gene shows high variability. The D47R form is relatively unresponsive to dopamine.
- Dopamine is degraded by COMT. The COMT gene includes a variant which is highly efficient reducing dopamine signalling but with complicating gene/environment interactions.
- Dopamine is removed from the synapse by a reuptake transporter DAT.

Memory formation in the cells of the hippocampus uses the MAP kinase signalling network which is impacted by sleep deprivation. The hippocampus dependent memory system is directly affected by cholinergic changes throughout the wake-sleep cycle. Increased acetylcholine during REM sleep promotes information attained during wakefulness to be stored in the hippocampus by suppressing previous excitatory connections while facilitating encoding without interference from previously stored information. During slow-wave sleep low levels of acetylcholine cause the release of the suppression and allow for spontaneous recovery of hippocampal neurons resulting in memory consolidation. It was initially associated with memory formation by McGill University's Dr. Brenda Milner, via studies of 'HM' Henry Molaison, whose medial temporal lobes had been surgically destroyed leaving him unable to create new explicit memories. The size of neurons' dendritic trees expands and contracts over a female rat's ovulatory cycle, with the peak in size and cognitive skills at the estrogen high point. Adult neurogenesis occurs in the hippocampus (3% of neurons are replaced each month) where the new neurons integrate into preexisting circuits. It is enhanced by learning, exercise, estrogen, antidepressants, environmental enrichment, and brain injury and inhibited by various stressors explains Sapolsky. Prolonged stress makes the hippocampus atrophy. He notes the new neurons are essential for integrating new information into preexisting schemas -- learning that two things you thought were the same are actually different. Specific cells within the hippocampus and its gateway, the entorhinal cortex, are compromised by Alzheimer's disease. It directly signals area 25. into fear

to the BNST is the bed nucleus of the stria terminalis. It receives 'innate fear' signals from the central amygdala. It projects to: Parts of the hypothalamus that initiate the hormonal stress response, Midbrain and brain-stem networks that activate the sympathetic nervous system and inhibit the parasympathetic. Winning in competition induces the addition of testosterone receptors increasing the sensitivity of the BNST to the hormone. That will lead to reduced fear and increased confidence. . It signals, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy. the locus ceruleus and its projections determine the brain's global orientation concerning events in the external world and within the viscera. It is signalled by the amygdala. Such a hypothesis of central noradrenergic neuron function has been generated by observations of locus ceruleus unit discharge in untreated, awake, behaviorally responsive rats and monkeys. These studies reveal the locus ceruleus units to be highly responsive to a variety of non-noxious sensory stimuli and that the responsiveness of these units varies as a function of the higher animal's level of behavioral vigilance. Increased neuronal activity in the locus ceruleus is associated with unexpected sensory events in the subject's external environment, while decreased noradrenergic activity is associated with mediating tonic vegetative behaviors. Sapolsky argues that arousal spread through the locus ceruleus to many brain regions, particularly the cortex, increases the intensity of what is sensed. . It
directly signals area 25 is the Subcallosal Cingulate Cortex, an area of the ACC, which Kandel explains, is a region where thought, motor control and drive come together. It is rich in neurons generating serotonin transporters. It is directly involved in a signalling network with: amydala, hypothalamus, hippocampus, insula cortex; that integrates thinking and emotion to plan and respond effectively. Kandel notes whenever area 25 becomes hyperactive, the components of this circuit associated with emotion are disconnected from the thinking brain resulting in a loss of personal identity. .
The amygdala:
- Promotes aggression. Stimulating the amygdala
promotes rage. It converts anger is an emotion which protects a person who has been cheated by a supposed friend. When the exploitation of the altruism is discovered, Steven Pinker explains, the result is a drive for moralistic aggression to hurt the cheater. Anger is mostly experienced as a rapid wave that then quickly dissipates. When it is repressed, for example by a strong moral sense (superego), it can sustain, inducing long term stress.
into aggression and when impaired it impacts the ability
to detect angry facial expressions.
- Participates in disgust is a universal human emotion. Pinker notes it has its own facial expression and is codified in food taboos. The mind must be associated with the proximate environment and parents minimize the risk for their omnivorous children by teaching them what foods to eat and what to avoid. The children's minds are initially receptive to trying all foods but their brains subsequently lock in on the foods they have experienced. These parental choices are affected by schematic influence on what has been beneficial. Adolescent's brain developments undermine these constraints enabling intergroup transfers. Disgust is modulated by the insula cortex which projects signals to the amygdala. Adult humans merge moral and physical disgust enabling metaphorical out grouping.
- Perceives fear is an emotion which prepares the body for time sensitive action: Blood is sent to the muscles from the gut and skin, Adrenalin is released stimulating: Fuel to be released from the liver, Blood is encouraged to clot, and Face is wide-eyed and fearful. The short-term high priority goal, experienced as a sense of urgency, is to flee, fight or deflect the danger. There are both 'innate' - really high priority learning - which are mediated by the central amygdala and learned fears which are mediated by the BLA which learns to fear a stimulus and then signals the central amygdala. Tara Brach notes we experience fear as a painfully constricted throat, chest and belly, and racing heart. The mind can build stories of the future which include fearful situations making us anxious about current ideas and actions that we associate with the potential future scenario. And it can associate traumatic events from early childhood with our being at fault. Consequent assumptions of our being unworthy can result in shame and fear of losing friendships. The mechanism for human fear was significantly evolved to protect us in the African savanna. This does not align perfectly with our needs in current environments: U.S. Grant was unusually un-afraid of the noise or risk of guns and trusted his horses' judgment, which mostly benefited his agency as a modern soldier.
promoting
stimuli, focusing our attention on these. In PTSD is post-traumatic stress disorder, an induced level of stress that is so troubling to the brain that it avoids processing it, change that is necessary if the stress is to be dissipated by the normal brain processes. The hippocampus loses volume. The damage to the hippocampus results in: flashbacks, becoming emotionally numb and withdrawn from other people, irritability, jumpiness, being more aggressive, having trouble sleeping and avoidance of the sensory experiences associated with the initial event. The amygdala responds to overwhelming trauma by repeatedly grabbing attention to encourage response to the emergency, increases in volume and is hyperactive and anxious. As a result it remains in a heightened state, resulting in fear of recall and further stress. PTSD is often accompanied by depression and substance abuse. It is now being realized that PTSD can be introduced into patients by traumatic treatment regimens such as ICU procedures. Traumatic head injuries, seen in athletes and soldiers can be reflected in PTSD and can subsequently become associated with prion based dementia. Some people are genetically predisposed to PTSD, with identical twins responding similarly. Another risk factor for PTSD is childhood trauma which can induce epi-genetic changes to stress processing. PTSD can be managed with CBT, and it also responds to propranolol while recalling the traumatic event, where the drug undermines the memory reconsolidation process. sufferers the Amygdala

in size refers to lasting changes to the brain that occur throughout the life span of the organism. Many aspects of the brain can be altered into adulthood. Almost anything in the nervous system can change in response to sustained stimulus. And in a different environment the changes will often reverse. The changes include: - The strength of dendritic input alters due to genetic, neural and hormonal signals
- Hebb notes that memories require strengthening of preexisting synapses. Glutamate responsive neurons' post synaptic dendritic spines have two types of receptor: non-NMDA and NMDA. NMDA channels are responsible for this strengthening mechanism. LTP then occurs to prolong the increase in excitability of the synapse.
- The LTP operation results in calcium diffusion which triggers new spine formation in adjacent parts of the dendrite. Eventually that can stimulate dentrite growth enabling more neurons to connect.
- Short term stress promotes hippocampal LTP.
- Sustained stress promotes:
- Hippocampal & frontal cortex LTD & suppresses LTP. Subsequent reductions in NCAM then reduce dendrite and synapse density.
- Amygdala LTP and suppresses LTD boosting fear conditioning. It increases BDNF levels and expands dendrites in the BLA.
- Depression and anxiety reduce hippocampal dendrite and spine number by reducing BDNF.
- The axon's conditions for
- Initiating an action potential.
- Progesterone boosts GABA-ergic neurons response to GABA decreasing the excitability of other neurons over a period of hours.
- Duration of a neuron's refractory period. Testosterone shortens the refractory period of amygdala and amygdala target neurons over a period of hours.
- Synaptic connections being constantly removed and recreated
- Synapses being created or destroyed. Stimulation generates additional dendritic spines which become associated with a nearby axon terminal and within weeks a synapse forms. The synapse then contributes calcium diffusion through LTP triggering more spine formation. When dendritic spines recede synapses disappear.
- Cortical maps change to reflect alterations in the inputs and outputs from the body.
- Birth of brain cells in many areas of adult brains: the hippocampus (where 3% are replaced each month) and olfactory bulb and lesser amounts in the cortex.
- Restructuring after brain damage including axonal plasticity. Distant rerouting of axons is observed but no mechanism has been identified yet.

processed by the lateral nucleus is the basolateral amygdala, a relatively recently evolved part of the amygdala which learns stimuli to fear and then signals the central amygdala. It recieves inputs from all sensory networks. Some are fast pathways that allow the BLA to detect and respond when the sensory cortex is unaware. But it is far less accurate than the cortex. The BLA's learning involves increased excitability of synapses coupling the BLA and central amygdala. This is due to gene driven: Increased levels of growth factors promoting new connections, more receptors for excitatory neurotransmitters in dendritic spines. The BLA also responds to signals from the frontal cortex that a stimulus no longer appears frightening. This subset of BLA cells respond inhibiting the associating subset. Stress and glucocorticoids increase levels of CRH and BDNF encouraging the building of new dendrites and synapses.

- Has lots of receptors is NR3C1 a receptor deployed in several forms, to which cortisol and other glucocorticoids bind. It regulates transcription of genes controlling development, metabolism and immune response. The unbound receptor resides in the cytosol. Gene/environment interactions have been identified:
- One variant of the gene for the MR receptor in the presence of childhood abuse produces an amydala that is hyperactive to threat.
- The GR receptor's activity is modified by FKBP5. Once FKBP5 variant in the presence of childhood abuse is associated with: aggression, hostility, PTSD, hyperreactivity of the amygdala to threat.
for and is highly sensitive to glucocorticoids are corticosteroids which bind the glucocorticoid receptor. They decrease excitability of prefrontal cortical neurons. They have adverse effects in fetal/infant development having organizational effects on fetal brain construction and decreasing levels of: growth factors, neurons, synapses; resulting in an adult brain that is more sensitive to environmental triggers of depression and anxiety. Glucocorticoids affect gene control structures and induce epi-genetic changes. They have been found associated with high sodium chloride consumption (May 2017). . Stress is a multi-faceted condition reflecting high cortisol levels. Dr. Robert Sapolsky's studies of baboons indicate that stress helps build readiness for fight or flight. As these actions occur the levels of cortisol return to the baseline rate. A stressor is anything that disrupts the regular homeostatic balance. The stress response is the array of neural and endocrine changes that occur to respond effectively to the crisis and reestablish homeostasis. - The short term response to the stressor
- activates the amygdala which: Stimulates the brain stem resulting in inhibition of the parasympathetic nervous system and activation of the sympathetic nervous system with the hormones epinephrine and norepinephrine deployed around the body, Activates the PVN which generates a cascade resulting in glucocorticoid secretion to: get energy to the muscles with increased blood pressure for a powerful response. The brain's acuity and cognition are stimulated. The immune system is stimulated with beta-endorphin and repair activities curtail. In order for the body to destroy bacteria in wounds, pro-inflammatory cytokines increase blood flow to the area. The induced inflammation signals the brain to activate the insula and through it the ACC. But when the stressor is
- long term: loneliness, debt; and no action is necessary, or possible, long term damage ensues. Damage from such stress may only occur in specific situations: Nuclear families coping with parents moving in. Sustained stress provides an evolved amplifier of a position of dominance and status. It is a strategy in female aggression used to limit reproductive competition. Sustained stress:
- Stops the frontal cortex from ensuring we do the harder thing, instead substituting amplification of the individual's propensity for risk-taking and impairing risk assessment!
- Activates the integration between the thalamus and amygdala.
- Acts differently on the amygdala in comparison to the frontal cortex and hippocampus: Stress strengthens the integration between the Amygdala and the hippocampus, making the hippocampus fearful.
- BLA & BNST respond with increased BDNF levels and expanded dendrites persistently increasing anxiety and fear conditioning.
- Makes it easier to learn a fear association and to consolidate it into long-term memory. Sustained stress makes it harder to unlearn fear by making the prefrontal cortex inhibit the BLA from learning to break the fear association and weakening the prefrontal cortex's hold over the amygdala. And glucocorticoids decrease activation of the medial prefrontal cortex during processing of emotional faces. Accuracy of assessing emotions from faces suffers. A terrified rat generating lots of glucocorticoids will cause dendrites in the hippocampus to atrophy but when it generates the same amount from excitement of running on a wheel the dendrites expand. The activation of the amygdala seems to determine how the hippocampus responds.
- Depletes the nucleus accumbens of dopamine biasing rats toward social subordination and biasing humans toward depression.
- Disrupts working memory by amplifying norepinephrine signalling in the prefrontal cortex and amygdala to prefrontal cortex signalling until they become destructive. It also desynchronizes activation in different frontal lobe regions impacting shifting of attention.
- Increases the risk of autoimmune disease (Jan 2017)
- During depression, stress inhibits dopamine signalling.
- Strategies for stress reduction include: Mindfulness.

where it promotes anxiety is manifested in the amygdala mediating inhibition of dopamine rewards. Anxiety disorders are now seen as a related cluster, including PTSD, panic attacks, and phobias. Major anxiety, is typically episodic, correlated with increased activity in the amygdala, results in elevated glucocorticoids and reduces hippocampal dendrite & spine density. Some estrogen receptor variants are associated with anxiety in women. Women are four times more likely to suffer from anxiety. Louann Brizendine concludes this helps prepare mothers, so they are ready to protect their children. Michael Pollan concludes anxiety is fear of the future. Sufferers of mild autism often develop anxiety disorders. Treatments for anxiety differ. 50 to 70% of people with generalized anxiety respond to drugs increasing serotonin concentrations, where there is relief from symptoms: worry, guilt; linked to depression, which are treated with SSRIs (Prozac). Cognitive anxiety (extreme for worries and anxious thoughts) is also helped by yoga. But many fear-related disorders respond better to psychotherapy: psychoanalysis, and intensive CBT. Tara Brach notes that genuine freedom from fear is enabled by taking refuge.

rejecting an unacceptable offer, as allowed in the Ultimatum Game is an economic game involving two players: One makes an offer about how to split a pot of money. If the offer is rejected neither party gets any money. The other player can accept or reject the offer. Rationality implies that any offer should be accepted by the recipient. Instead recipients are keenly aware of being unfairly treated. The longer the amygdala responds to the offer the more likely it is to be rejected. The rejection is mentally costly and must be encouraged by a dopaminergic reward, fueled by the amygdala and insula. When the offer is rejected the first player feels dissed, subordinated - especially if the result is shared with others, undermining status & reputation. Sapolsky notes that: - People with damaged amygdalae are unusually generous because the BLA normally injects learned implicit distrust and vigilance into social decision making.
- People given testosterone before the game become more generous. Sapolsky notes the effect demands fancy neuroendocrine wiring.
- People from small-scale, non-Western cultures were less trusting and punished more. Joseph Henrich found three variables predicted how the play executed: Market integration, Community size, Religion; where large communities need ways to make strangers trustworthy. Communities that trade are also more likely to act fairly and punish unfairness. Sapolsky asserts that market interactions represent an impoverishment of human reciprocity with the total transaction having to be judged and occur in an instant. Small-scale cultures are more practiced at the nuanced judgements about their long term neighbors.
- Chimps can be trained to play the game. Max Planck Institute's Michael Tomasello found no evidence of chimp requirements for fairness. But De Waal & Brosnan found chimps will be fair but only if they see a downside in being unfair. Primates seem to reflect the same hypocritical strategies underneath any reciprocal altruism that humans display.

The amygdala is very rapidly excited by subliminal signals
from the thalamus has all the main inputs to the cortex passing through it. It is massively supplied with return innervations from the cortical regions it routes too. It does not stand on the route of the main exits from the cortex. The parafascicular nucleus of the rat thalamus contains relatively high levels of D5 dopamine receptors. For human vision the primary system connects to the neocortex via, a small part of the thalamus, the LGN. of outgroup
skin color. The amygdala subsequently tips social emotions are emotions that are induced in response to other people's signals, are implemented by specific brain regions including: Prefrontal cortex, Insula cortex, Anterior cingulate cortex, Amygdala; receive lots of projections from interoceptive networks. Sapolsky asserts in the moments just before we prioritize a consequential act the process is less rational and autonomous than we assume. There are many significant signals from the prior seconds to minutes that effect social emotions: - Our brains respond subliminally to skin color very quickly: Amygdala activates, Fusiform face area activates; prior to the conscious stream activating the anterior cingulate and DLPFC which then inhibit the amygdala.
- Social dominance is culture independent and accurately subliminally assessed after a 40-millisecond exposure. Stable status relations activate the ventromedial prefrontal cortex and DLPFC, while a dynamic situation also activates the amygdala.
- People who are subliminally judged attractive by the medial orbitofrontal cortex are considered kinder, smarter and more honest. They are given more breaks.
- Faces and eyes in particular are most important subliminal cues. They are monitored by the fusiform. People respond more appropriately under the subliminal influence of eyes.
- Olfactory sensors send more direct projections to the limbic network than other sensory networks. Pheromones signal fear activating the amygdala.
- Observing pain responses in others results in empathy even among young children.
- Words are important emotional signals providing unconscious priming of social responses. Kahneman & Tversky demonstrated how the phrase '95% survival rate' is found to be a more acceptable choice than '5% death rate'. Sapolsky notes that prosocial word priming fosters cooperation with antisocial word priming doing the opposite.
- Cultural objects such as visible: flags, team badges; subliminally modify in-group outgroup decisions.
- The presence of women in a situation alters the responses of men: Increased risk-taking, more focus on luxuries, increased aggression; in circumstances where conflict is already encouraged but not when status is achieved prosocially.
- Physical environment shapes behavior as demonstrated by Philip Zimbardo and leveraged in broken windows policing.
- Bodily adjustments to sensory structures introduce adaptive complexity, with the brain being influenced to become more sensitive and alter the sensor networks to make some more sensitive. But these adaptations also vary culturally. Collectivist cultures focus on a visual scene's surrounding contextual information while people from individualistic cultures focus on the focal object!

outgroups unless restrained by the frontal lobe of the cerebral cortex is at the front of the brain. It includes the: prefrontal cortex, motor cortex. Sapolsky asserts it makes you do the harder thing when it's the right thing to do. The frontal cortex supports working memory to sustain focus on a task. It also coordinates the strategic actions necessary to achieve success. It provides impulse control, regulation of emotion, and willpower. The prefrontal cortex maintains focus by deprioritizing currently irrelevant streams of information. The frontal cortex tracks rules. Over a lifetime, that builds into a costly activity. Once it tires, responses become less prosocial. But practice shifts operation of tasks to the cerebellum. The frontal cortex signals the tegmentum and accumbens with the conclusions of its expectancy/discrepancy calculations. The frontal lobe provides executive function, considering bits of information, assessing patterns and then prioritizing the strategies. The frontal lobe is the most recent part of the brain to evolve and involves a disproportionate percentage of primate-unique genes in its development and operation. It does not complete development until the mid-20s. It includes spindle neurons. It is easily damaged. Sapolsky (Nauta) notes that its ventromedial prefrontal cortex is a quasi-member of the limbic system. or influenced

- Sees suffering of others as increasingly salient, Douglas Hofstadter controlled the amount of attention a Workspace object in Copycat would receive from codelets via its salience. The more descriptions, analogous to geons, an object has and the more highly activated the nodes involved therein, the more important the object is. Modulating this tendency is any relative lack of connections from the object to the rest of the objects in the Workspace. Salience is a dynamic number that takes into account both these factors. In Smiley the instantaneous salience of a Workspace's objects is calculated by itsalience. In the brain salience is modeled by the salience networks.

Goleman had travelled to Sri Lanka to understand an Asian model
of the mind, which he presented to the undergraduates at
Harvard. Goleman and Davidson developed it into a shared vision of
consciousness. It took over twenty years for
scientific theory and experimental data to catch up and align
with this model. Much of the prior
experimental data had to be abandoned.
They introduce meditation's

They look at the changes in:

They detail how scientists were able to study the brains of Tibetan meditation masters,
starting with Mingyur Rinpoche,
and detect meditation altering

select a model that seems to match and anchor to that.
When the actual operation diverges from the anchor model,
the agents continue to leverage the model, but make
adjustments to account for the differences. If a
characteristic of the network, such as increased demand, has
changed the model and adjustments will generate more
divergence. In a network with buffer pools and Carlo Rovelli resolves the paradox of time.
Rovelli initially explains that low level physics does not
include time:
- A present that is common throughout the universe does not exist
- Events are only partially ordered. The present is
localized
- The difference between past and future is not foundational.
It occurs because of state that through our blurring appears
particular to us
- Time passes at different speeds dependent on where we are and how fast we travel
- Time's rhythms are due to
the gravitational field
- Our quantized physics shows neither
space nor time, just processes transforming physical
variables.
- Fundamentally there is no time. The basic equations
evolve together with events, not things
Then he
explains how in a physical world without time its perception can
emerge:
- Our familiar time emerges
- Our interaction with the world is partial, blurred,
quantum indeterminate
- The ignorance determines the existence of thermal time
and entropy that quantifies our uncertainty
- Directionality of time is real
but perspectival. The entropy of the world in
relation to us increases with our thermal time. The
growth of entropy distinguishes past from future: resulting in
traces and memories
- Each human is a
unified being because: we reflect the world, we
formed an image of a unified entity by
interacting with our kind, and because of the perspective
of memory
- The variable time: is one
of the variables of the gravitational field.
With our scale we don't
register quantum fluctuations, making space-time
appear determined. At our speed we don't perceive
differences in time of different clocks, so we experience
a single time: universal, uniform, ordered; which is
helpful to our decisions
time delays, the anchor and adjust

These hormones stimulate the growth of prostrate cancer is cancer of the prostate gland. Genomics detected several common DNA variants associated with increased risk of prostate cancer. Dr. Francis Collins explains that a cluster of these risk variants lies in a stretch of 1 million DNA base pairs on chromosome 8. The cluster contains seven or more risk variants, each of which can raise the risk of prostate cancer by 10 to 30%. The high risk variants occur more frequently in African-American men than European or Asians. African-Americans die from prostate cancer at more than twice the rate of Europeans. Research in mice may explain a link between obesity and prostate cancer (Jan 2018). The average diagnosis is at age 66. Worldwide in 2012 there were 1.1 million cases from which 307,000 died. A common life-saving (Feb 2017) treatment is androgen deprivation therapy, but it has worrying side effects. Various classically defined types of cancer can occur. The most common is adenocarcinoma associated with the epithelial gland cells that generate seminal fluid. Epithelial cell differentiation potency makes these significant cancer agents. Other very rare types of cancer that can start in the prostate are: - Sarcomas
- Small cell carcinomas
- Neuroendocrine tumors

associated with increased rates of: Depression is a debilitating episodic state of extreme sadness, typically beginning in late teens or early twenties. This is accompanied by a lack of energy and emotion, which is facilitated by genetic predisposition - for example genes coding for relatively low serotonin levels, estrogen sensitive CREB-1 gene which increases women's incidence of depression at puberty; and an accumulation of traumatic events. There is a significant risk of suicide: depression is involved in 50% of the 43,000 suicides in the US, and 15% of people with depression commit suicide. Depression is the primary cause of disability with about 20 million Americans impacted by depression at any time. There is evidence of shifts in the sleep/wake cycle in affected individuals (Dec 2015). The affected person will experience a pathological sense of loss of control, prolonged sadness with feelings of hopelessness, helplessness & worthlessness, irritability, sleep disturbances, loss of appetite, and inability to experience pleasure. Michael Pollan concludes depression is fear of the past. It affects 12% of men and 20% of women. It appears to be associated with androgen deprivation therapy treatment for prostate cancer (Apr 2016). Chronic stress depletes the nucleus accumbens of dopamine, biasing humans towards depression. Depression easily leads to following unhealthy pathways: drinking, overeating; which increase the risk of heart disease. It has been associated with an aging related B12 deficiency (Sep 2016). During depression, stress mediates inhibition of dopamine signalling. Both depression and stress activate the adrenal glands' release of cortisol, which will, over the long term, impact the PFC. There is an association between depression and additional brain regions: Enlarged & more active amygdala, Hippocampal dendrite and spine number reductions & in longer bouts hippocampal volume reductions and memory problems, Dorsal raphe nucleus linked to loneliness, Defective functioning of the hypothalamus undermining appetite and sex drive, Abnormalities of the ACC. Mayberg notes ACC area 25: serotonin transporters are particularly active in depressed people and lower the serotonin in area 25 impacting the emotion circuit it hubs, inducing bodily sensations that patients can't place or consciously do anything about; and right anterior insula: which normally generates emotions from internal feelings instead feel dead inside; are critical in depression. Childhood adversity can increase depression risk by linking recollections of uncontrollable situations to overgeneralizations that life will always be terrible and uncontrollable. Sufferers of mild autism often develop depression. Treatments include: CBT which works well for cases with below average activity of the right anterior insula (mild and moderate depression), UMHS depression management, deep-brain stimulation of the anterior insula to slow firing of area 25. Drug treatments are required for cases with above average activity of the right anterior insula. As of 2010 drug treatments: SSRIs (Prozac), MAO, monoamine reuptake inhibitors; take weeks to facilitate a response & many patients do not respond to the first drug applied, often prolonging the agony. By 2018, Kandel notes, Ketamine is being tested as a short term treatment, as it acts much faster, reversing the effect of cortisol in stimulating glutamate signalling, and because it reverses the atrophy induced by chronic stress. Genomic predictions of which treatment will be effective have not been possible because: Not all clinical depressions are the same, a standard definition of drug response is difficult; (Apr
2016), Dementia is a classification of memory impairment, constrained feelings and enfeebled or extinct intellect. The most common form for people under 60 is FTD. Dementia has multiple causes including: vascular disease (inducing VCI) including strokes, head trauma, syphilis and mercury poisoning for treating syphilis, alcoholism, B12 deficiency (Sep 2016), privation, Androgen deprivation therapy (Oct 2016), stress, Parkinson's disease, Alzheimer's disease, and prion infections such as CJD and kuru. The condition is typically chronic and treatment long term (Laguna Honda ward) and is predicted by Stanley Prusiner to become a major burden on the health system. It may be possible to constrain the development some forms of dementia by: physical activity, hypertension management, and ongoing cognitive training. Dementia appears to develop faster in women than men. (Oct
2016) including Alzheimer's
disease is a dementia which correlates with deposition of amyloid plaques in the neurons. As of 2015 there are 5 million Alzheimer's patients in the USA. It was originally defined as starting in middle age which is rare, so it was a rare dementia. But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI). Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged. The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease. Grid cell destruction results in a sense of being lost. The default mode network is disrupted. Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes. There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016). The Alzheimer's pathway follows: - Plaques form. These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes. APP deployed in the cell membrane is cut into three parts. The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough.
- Solanezumab aimed to inhibit plaque formation but clinical trials failed (Nov 2016).
- Encouraging the garbage collection of amyloid and tau with gamma rhythms stimulation retards Alzheimer's in mice studies (Mar 2019)
- BACE inhibitors block an enzyme needed to form amyloid.
- Mutation driven misfolded Tau proteins can form tangles within the cytoplasm of neurons. The Tau tangles kill nerve cells. LMTX is a drug treatment targeted at these tangles.
- The brain becomes inflamed resulting in the killing of many more nerve cells. The hippocampus disintegrates and the brain loses critical functions and memory loss becomes noticeable.

- Androgens are a class of steroid hormones
including testosterone is a hormone secreted by the testes, ovaries, and adrenal glands, in response to stimulation from the hypothalamic/pituitary/testicular cascade, that makes humans more willing to do what it takes to attain and maintain status, according to Sapolsky. That means players of the Ultimatum Game, if previously given testosterone can become more generous. High testosterone in a fetus masculinizes the brain. Males generate 10 times the amount. It is the trigger for sexual desire in males and females, stimulating the hypothalamus. Testosterone's effect is highly socially contextual so it may encourage acts of kindness or aggression (when challenged). The level of testosterone does not predict which individuals will be aggressive in: Birds, Fish, Mammals including primates. Genes impact the potency of testosterone by altering the enzymes that: Construct it, Convert it to estrogen, code the androgen receptor. This androgen receptor includes a variable polyglutamine repeat which alters the sensitivity to the testosterone signal. The more potent form is associated with boys showing more dramatic 'masculinization' of the cortex. But the detected genetic influences are small. Testosterone decreases activity in the prefrontal cortex and its functional coupling to the amygdala while increasing the coupling between the amygdala & the thalamus. Testosterone shortens the refactory period of amygdaloid & amygdaloid target neurons. This results in impulsive risk taking and more focus on unfamiliar faces and distrust of them. Testosterone increases activity in the ventral tegmentum projecting dopamine to enhance place preference. Winners of fights become more willing to fight in part due to testosterone increasing confidence and optimism and reducing fear and anxiety. And winning at: Chess, Athletics, Stock trades; induces the BNST to add testosterone receptors increasing its sensitivity to the hormone. People become overconfident and overly optimistic.

androstenedione and dihydrotestosterone. They are
precursors of estrogens is a generic term for a number of related steroid hormones each of which works differently. Estrogen: - Is generated in the ovaries. It supports the generation of oxytocin, and so is associated with attachment, nurturing and other affiliative behaviors.
- Supports verbal memory. Removal of ovaries without immediate estrogen replacement therapy degrades verbal memory performance. The HT reduces age-related shrinkage of the PFC, parietal cortex, and temporal lobe in women, and made them less depressed and angry.
- Supports mitochondrial operation in the blood vessels of the brain.
- Contributes to maternal aggression but it can reduce aggression and enhance empathy, depending on brain state. There are two different estrogen receptor types which mediate these conflicting effects. The level of each type of receptor is independently regulated. Different receptor variants are associated with:
- Higher rates of anxiety among women
- Higher rates of antisocial behavior and conduct disorder in men
- Is essential for vaginal lubrication
- Facilitates the elimination of cholesterol
- Has anti-inflammatory and anti-oxidative properties improving response to stress
.
- Anemia
is a decrease in the number of red blood cells or the amount
of hemoglobin in the blood. There are various types: Fanconia anemia is a recessive disease where the bone marrow fails to produce red and white cells. PGD has been used to select for embryos that do not have the Fanconi mutation and are a transplantation match for a suffering sibling, and that would result in a baby whose umbilical cord can be used to generate stem cell bone marrow for transplant to a sibling already born with the anemia.
, Iron-deficiency anemia is anemia caused by lack of iron. It is generally caused by loss of blood, insufficient dietary iron, poor absorption of iron. ,
Pernicious anemia is an autoimmune disease with a deficiency in red blood cells due to a lack of intrinsic factor limiting absorbtion of vitamin B12. The cells in the stomach that make intrinsic factor are damaged by the autoimmune attack by antibodies to intrinsic factor. , Sickle-cell anemia is a recessive single gene disease where the sufferer's hemoglobin causes the red blood cells to distort. It is a side effect of the evolved protection from malaria provided by sickle cell trait. Potential treatments include gene therapy and drugs that block the sickling of red blood cells. Carrier screening was undermined by there being no effective prenatal test limiting the benefit of the information and because the white doctors were not trusted by their black patients. In the future iPS cells could have the problem mutations replaced with ex vivo gene therapy. ;

or general induces a deep sleep that suppresses breathing and vigilance and often requires a breathing tube. This is far more risky than sedation. Researchers are actively looking at the impacts on children under three years old including SmartTots since: - Studies of children have found an association between learning problems and multiple exposures to anesthesia early in life.
- Experiments in young monkeys have shown that commonly used anesthetics and sedatives can kill brain cells, diminish learning and memory and cause behavior problems.

- Anger
is an emotion are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism.

It is differentiated from kin altruism, by Williams and Trivers, since it can apply between unrelated individuals. It can be induced by natural selection when there is mutual survival benefit in group activities and cheating can be detected and discouraged. Humans, leveraging the cognitive niche, can particularly easily, build an evolved amplifier, through sharing information at little cost and significant benefit. But African savanna hunters similarly gain from sharing large game meat with other un-related altruistic group members since the meat would otherwise spoil before it could be eaten. is discovered,

to develop his psychological arguments about the mind and its

These conclusions allow him to understand the development and

result is a drive for moralistic provides rules for identifying right from wrong. It develops in stages with children using play to work out rules of appropriate behavior. Kohlberg's 1950s experiments using children led him to conclude moral judgement is a cognitive process that develops in three stages. Sapolsky raises issues with the framework: Its a model, It does not apply to other cultures, Intuition & emotion are as significant as cognition, Moral reasoning doesn't predict moral actions; and notes the capacity of the frontal cortex to regulate emotions and behavior is far more predictive. The marshmallow test, performed on three to six year olds, actually predicted their subsequent SAT scores at high school, social success and lack of aggression, and forty years on more PFC activation during a frontal task and a lower BMI! Jonathan Haidt argues people's moral decisions are rationalizations rather than using reasoning.

experienced as a rapid wave that then quickly
dissipates. When it is repressed in Freud's structural model, is the mind's unconscious defense mechanism to shift its desires and impulses towards pleasurable instincts by excluding other: distressing memories, thoughts, feelings; from consciousness. Freud's free-association method revealed his patients' subconscious operation and inconsistencies: professed love associated with actual hate, indignant morality concealing perverse desires, nonconformity concealing guilt; where they were keeping these things hidden, that are present in the adaptive unconscious. ,
for example by a
strong moral sense is psychologist Jonathan Haidt's classification of primary themes that are drivers of human moral decision making. Anthropologists have identified the themes across cultures. Haidt concludes people don't engage in moral reasoning, but moral rationalization. As Steven Pinker explains in The Moral Instinct, once the moral decision switch is active these themes will gain precedence. They include: - Harm
- Fairness
- Community
- Authority
- Purity; but what acts are associated with each theme is culturally learned. For example smoking can be taught to be viewed as a fun pleasure or associated with harm and so morally reprehensible.

stress is a multi-faceted condition reflecting high cortisol levels. Dr. Robert Sapolsky's studies of baboons indicate that stress helps build readiness for fight or flight. As these actions occur the levels of cortisol return to the baseline rate. A stressor is anything that disrupts the regular homeostatic balance. The stress response is the array of neural and endocrine changes that occur to respond effectively to the crisis and reestablish homeostasis. - The short term response to the stressor
- activates the amygdala which: Stimulates the brain stem resulting in inhibition of the parasympathetic nervous system and activation of the sympathetic nervous system with the hormones epinephrine and norepinephrine deployed around the body, Activates the PVN which generates a cascade resulting in glucocorticoid secretion to: get energy to the muscles with increased blood pressure for a powerful response. The brain's acuity and cognition are stimulated. The immune system is stimulated with beta-endorphin and repair activities curtail. In order for the body to destroy bacteria in wounds, pro-inflammatory cytokines increase blood flow to the area. The induced inflammation signals the brain to activate the insula and through it the ACC. But when the stressor is
- long term: loneliness, debt; and no action is necessary, or possible, long term damage ensues. Damage from such stress may only occur in specific situations: Nuclear families coping with parents moving in. Sustained stress provides an evolved amplifier of a position of dominance and status. It is a strategy in female aggression used to limit reproductive competition. Sustained stress:
- Stops the frontal cortex from ensuring we do the harder thing, instead substituting amplification of the individual's propensity for risk-taking and impairing risk assessment!
- Activates the integration between the thalamus and amygdala.
- Acts differently on the amygdala in comparison to the frontal cortex and hippocampus: Stress strengthens the integration between the Amygdala and the hippocampus, making the hippocampus fearful.
- BLA & BNST respond with increased BDNF levels and expanded dendrites persistently increasing anxiety and fear conditioning.
- Makes it easier to learn a fear association and to consolidate it into long-term memory. Sustained stress makes it harder to unlearn fear by making the prefrontal cortex inhibit the BLA from learning to break the fear association and weakening the prefrontal cortex's hold over the amygdala. And glucocorticoids decrease activation of the medial prefrontal cortex during processing of emotional faces. Accuracy of assessing emotions from faces suffers. A terrified rat generating lots of glucocorticoids will cause dendrites in the hippocampus to atrophy but when it generates the same amount from excitement of running on a wheel the dendrites expand. The activation of the amygdala seems to determine how the hippocampus responds.
- Depletes the nucleus accumbens of dopamine biasing rats toward social subordination and biasing humans toward depression.
- Disrupts working memory by amplifying norepinephrine signalling in the prefrontal cortex and amygdala to prefrontal cortex signalling until they become destructive. It also desynchronizes activation in different frontal lobe regions impacting shifting of attention.

signals, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy. (angiotensin II) from

GWAS is genome-wide association study which examines common genetic variants (mostly SNPs) of different individuals to find those common variants that are associated with a trait. Sample size has been made manageable by the HapMap SNP clustering strategy. To detect the uncommon variants with GWAS would be exponentially more costly and time consuming. So it can't be used to detect schizophrenia or autism SNPs which are associated with a significant reduction in reproductive fitness and will thus never become common in the population. suggest ANK3 SNP is single nucleotide polymorphism where single base pairs have changed in two chromosomes of the same type. There are 10 million common SNPs in the human genome. There are a limited number of chromosomal types (Haplotypes). This results in SNPs clustering into packs. On average 30 to 40 SNPs travel together. Knowing one or two SNPs in a local neighborhood predicts the others that are likely to be present. s

disorder also termed manic-depression is an episodic developmental disorder beginning in late adolescence, which can stimulate great creativity during the manic phase and suicide in the depressive phase. Vincent van Gough suffered from depression for much of his adult life, and killed himself at thirty seven. He produced three hundred of his greatest art works, using color to convey mood, while struggling with psychotic depression and mania in the last two years of his life. Only the first manic phase requires a significant positive or negative stressful situation. Type I bipolar includes more manic situations which may include psychosis. Type II does not include psychosis. Some people suffer 'mixed state' where mania and depression occur at the same time. Sleep deprivation activates the amygdala and can induce mania in some people with bipolar disorder. It affects 3 million Americans. The amygdala is more active in people with bipolar disorder. Franz Kallman found identical twins are likely (70% chance) to share the disorder. Swedish researchers studying thousands of families in 2009 showed a strong hereditary link between bipolar disorder and schizophrenia, which was corroborated in 2012. Genetic analysis of 2.3 million different regions of DNA of 9,747 people with bipolar disorder and 14,278 comparable people without, found five regions that appear connected with bipolar disorder. Gene ADCY2, was identified, supports production of an enzyme facilitating neural signalling, and correlates with observed impairment of communication in certain brain regions in bipolar disorder. GWAS implicate ANK3 and CACNA1C SNPs in bipolar disorder. And de Novo mutations increase the risk. Lithium limits the extremes of the mood swings in some patients but has side effects. Anti-psychotic medications are prescribed. .

acts as a reward with compliments relieving anxiety is manifested in the amygdala mediating inhibition of dopamine rewards. Anxiety disorders are now seen as a related cluster, including PTSD, panic attacks, and phobias. Major anxiety, is typically episodic, correlated with increased activity in the amygdala, results in elevated glucocorticoids and reduces hippocampal dendrite & spine density. Some estrogen receptor variants are associated with anxiety in women. Women are four times more likely to suffer from anxiety. Louann Brizendine concludes this helps prepare mothers, so they are ready to protect their children. Michael Pollan concludes anxiety is fear of the future. Sufferers of mild autism often develop anxiety disorders. Treatments for anxiety differ. 50 to 70% of people with generalized anxiety respond to drugs increasing serotonin concentrations, where there is relief from symptoms: worry, guilt; linked to depression, which are treated with SSRIs (Prozac). Cognitive anxiety (extreme for worries and anxious thoughts) is also helped by yoga. But many fear-related disorders respond better to psychotherapy: psychoanalysis, and intensive CBT. Tara Brach notes that genuine freedom from fear is enabled by taking refuge. and increasing
self-esteem. Diet gets paired with weight loss (the

involved in the patient's decision
making integrates situational context, state and signals to prioritize among strategies and respond in a timely manner. It occurs in all animals, including us and our organizations: - Individual human decision making includes conscious and unconscious aspects. Situational context is highly influential: supplying meaning to our general mechanisms, & for robots too. Emotions are important in providing a balanced judgement. The adaptive unconscious interprets percepts quickly supporting 'fast' decision making. Conscious decision making, supported by the: DLPFC, vmPFC and limbic system; can use slower autonomy. The amygdala, during unsettling or uncertain social situations, signals the decision making regions of the frontal lobe, including the orbitofrontal cortex. The BLA supports rejecting unacceptable offers. Moral decisions are influenced by a moral decision switch. Sleeping before making an important decision is useful in obtaining the support of the unconscious in developing a preference. Word framing demonstrates the limitations of our fast intuitive decision making processes. And prior positive associations detected by the hippocampus, can be reactivated with the support of the striatum linking it to the memory of a reward, inducing a bias into our choices. Prior to the development of the PFC, the ventral striatum supports adolescent decision making. Neurons involved in decision making in the association areas of the cortex are active for much longer than neurons participating in the sensory areas of the cortex. This allows them to link perceptions with a provisional action plan. Association neurons can track probabilities connected to a choice. As evidence is accumulated and a threshold is reached a choice is made, making fast thinking highly adaptive. Diseases including: schizophrenia and anorexia; highlight aspects of human decision making.
- Organisations often struggle to balance top down and distributed decision making: parliamentry government must use a process, health care is attempting to improve the process: checklists, end-to-end care; and include more participants, but has systemic issues, business leaders struggle with strategy.
making it a habit allow higher organisms: humans, rats, flies; to perform important behaviors automatically, without involvement of consciousness. Habits are adaptive, being promoted by the release of dopamine into the PFC and striatum, generating a feeling of pleasure and conditioning us. As the dopamine detaches from the synaptic receptors in the PFC and striatum the motivation to perform the behavior subsides. If the dopamine remains at the synapse for an extended period, because it is not removed as occurs when cocaine is present, or when too much dopamine is generated, the habit can become an addiction. .
- Anosognosia is unawareness of a major

- Anterior insula is a rich club hub are areas of the brain which are highly connected to other club hubs: Ventral anterior insula, Dorsal anterior cingulate cortex, Posterior orbitofrontal cortex, Parahippocampal gyrus, Temporal pole.
within the insula cortex is part of the cerebral cortex folded deep within the lateral sulcus. It includes: anterior, posterior insula; and is overlaid by the operculum. Kandel notes the anterior insula is where feelings are calibrated by evaluating and integrating the importance of the stimuli. It directly signals area 25. LeDoux showed there are two routes for signals of feelings and emotions to the amygdala: a fast unconscious one and a slow one that involves the anterior insula. So the insula is assumed to participate in consciousness where it has been linked to emotion, salience & body homeostasis functions: - Perception,
- Motor control: Hand-&-eye motor movement, Swallowing, Gastric motility, Speech articulation;
- Self-awareness,
- Inter-personal experiences: Disgust at smells, contamination & mutilation which generate visceral responses, that are projected to the amygdala; binding physical and moral aspects of purity (Macbeth effect)
- Suffering of others can be projected by the insula to the amygdala and made increasingly salient with loving-kindness meditation practice, Goleman & Davidson explain.
- Homeostatic regulation of the sympathetic network, parasympathetic network, and immune system. Heart rate and sweat gland activity are monitored. When the amygdala signals concern, the insula prepares the body for action, increasing blood flow to the muscles etc.

anatomically subdivided by sulci into gyri. It is
where self-awareness and social experience integrate.
Feelings are subjective models: sad, glad, mad, scared, surprised, and compassionate; of the organism and its proximate environment, including ratings of situations signalled by broadly distributed chemicals and neural circuits. These feelings become highly salient inputs, evolutionarily associated, to higher level emotions encoded in neural circuits: amygdala, and insula. Deacon shows James' conception of feeling can build sentience. Damasio, similarly, asserts feelings reveal to the conscious mind the subjective status of life: good, bad, in between; within a higher organism. They especially indicate the affective situation within the old interior world of the viscera located in the abdomen, thorax and thick of the skin - so smiling makes one feel happy; but augmented with the reports from the situation of the new interior world of voluntary muscles. Repeated experiences build intermediate narratives, in the mind, which reduce the salience. Damasio concludes feelings relate closely and consistently with homeostasis, acting as its mental deputies once organisms developed 'nervous systems' about 600 million years ago, and building on the precursor regulatory devices supplied by evolution to social insects and prokaryotes and leveraging analogous dynamic constraints. Damasio suggests feelings contribute to the development of culture: - As motives for intellectual creation: prompting detection and diagnosis of homeostatic deficiencies, identifying desirable states worthy of creative effort.
- As monitors of the success and failure of cultural instruments and practices
- As participants in the negotiation of adjustments required by the cultural process over time
from the internal state
of the body are used to generate emotions are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism. .

It receives simple signals from the lower parts of the brain: pain from the PAG; and abstract complex information from the highest areas: Disgust, heart rate, and suffering from the insula cortex, allowing it to orchestrate emotion. It connects strongly to attention focusing networks. It sends signals to almost every other part of the brain, including to the decision making circuitry of the frontal lobes. It has high levels of D(1) dopamine receptors. During extreme fear the amygdala drives the hippocampus into fear learning. It outputs directly to subcortical reflexive motor pathways when speed is required. Its central nucleus projects to the BNST. It signals the locus ceruleus. It directly signals area 25. The amygdala: - Promotes aggression. Stimulating the amygdala promotes rage. It converts anger into aggression and when impaired it impacts the ability to detect angry facial expressions.
- Participates in disgust
- Perceives fear promoting stimuli, focusing our attention on these. In PTSD sufferers the Amygdala overreacts to mildly fearful stimuli and is slow to calm down and the amygdala expands in size over a period of months. Fear is processed by the lateral nucleus which serves as the input from various senses, and the central nucleus which outputs to the brain stem (central grey - freezing, lateral hypothalamus - blood pressure, activates paraventricular hypothalamus => crf -> hormone adjustments).
- Has lots of receptors for and is highly sensitive to glucocorticoids. Stress inhibits the GABA interneurons in the basolateral amygdala (BLA) allowing the excitatory glutamate releasing neurons to excite more.
- Is sensitive to unsettling/uncertain social situations where it promotes anxiety and makes us distracted. It is also interested in uncertain but potentially painful situations. The amygdala contributes to social and emotional decision making where the BLA supports rejecting an unacceptable offer, as allowed in the Ultimatum Game, by injecting implicit mistrust and vigilance, generating an anger driven rejection that is used as punishment. The amygdala is very rapidly excited by subliminal signals from the thalamus of outgroup skin color. The amygdala subsequently tips social emotions against outgroups unless restrained by the frontal lobe or influenced by subliminal priming to prioritize inclusion.

kickback for a Medicare is a social insurance program that guarantees access to health insurance for Americans aged 65 and over, and younger people with disabilities and end stage renal disease or ALS. Medicare is currently missing a cap on out-of-pocket costs and direct prescription drug coverage. It includes: - Benefits
- Part A: Hospital inpatient insurance. As of Dec 2013 Medicare pays for home care in only limited circumstances, such as when a person needs temporary nursing care after a hospitalization. Part A covers 20 days of inpatient rehabilitation at a SNF after discharge from inpatient care at a hospital.
- Part B: Medical insurance for non-hospital services including: doctor visits, tests, injectable drugs, ambulances, physical therapy;
- Part C: Medicare Advantage
- Part D: indirect prescription drug coverage The MMA prohibits Medicare from directly negotiating drug prices.
- Eligibility
- All persons 65 years of age or older who are legal residents for at least 5 years. If they or a spouse have paid Medicare taxes for 10 years the Medicare part A payments are waived. Medicare is legislated to become the primary health plan.
- Persons under 65 with disabilities who receive SSDI.
- Persons with specific medical conditions:
- Have end stage renal disease or need a kidney transplant.
- They have ALS.
- Some beneficiaries are dual eligible.
- Part A requires the person has been admitted as an inpatient at a hospital. This is constrained by a rule that they stay for three days after admission.
- Sign-up
- Part A has automatic sign-up if the person is drawing social security. Otherwise the person must sign-up for Part A and Part B.
- Should sign-up for Part B during the Initial Enrollment Period, of seven months centered around 65th birthday, online or at a social security office. But if still covered by spouse's insurance or not yet retired then may only join during the 3 month general enrollment period (January to March) each year, with coverage initiated the following July. Incremental yearly 10% penalties apply for not signing up at 65. These penalties apply to all subsequent premiums.
- Premiums
- Part A premium
- Part B insurance premium
- Part C & D premiums are set by the commercial insurer.
or Medicaid is the state-federal program for the poor. Originally part of Lyndon Johnson's 1965 Bill, eligibility and services vary by state. Medicaid currently pays less for care than Medicare, resulting in many care providers refusing to participate in the program. Less than 10 percent of Medicaid recipients, those in long-term care including nursing homes where 64% are dependent on Medicaid, use one-third of all Medicaid spending which is a problem. The ACA's Medicaid expansion program, made state optional by the SCOTUS decision, was initially taken up by fifty percent of states. As of 2016 it covers 70 million Americans at a federal cost of $350 billion a year. In 2017 it pays for 40% of new US births. service referral links a doctors patient to an additional service as part of a treatment proposal.

World leaders now aims to develop plans and strategies which ensure effective coordination to improve the common good of the in-group. Pinker notes the evolved pressure of social rivalry associating power with leadership. Different evolved personality types reinforced during development provided hunter-gatherer bands with alternate adult capabilities for coping with the various challenges of the African savanna. As the situation changed different personalities would prove most helpful in leading the band. Big men, chiefs and leaders of early states leveraged their power over the flow of resources to capture and redistribute wealth to their supporters. As the environmental state changed and began threatening the polity's fitness, one leader would be abandoned, replaced by another who the group hoped might improve the situation for all. Sapolsky observes the disconnect that occurs between power hierarchies and wisdom in apes. In modern Anglo-American style corporations, which typically follow Malthus, and are disconnected from the superOrganism nest site, the goal of leadership has become detached from the needs of this broader polity, instead: seeking market and revenue growth, hiring and firing workers, and leveraging power to reduce these commitments further. Dorner notes that corporate executives show an appreciation of how to control a CAS. Robert Iger with personality types: Reformer, Achiever, Investigator; describes his time as Disney CEO, where he experienced a highly aligned environment, working to nurture the good and manage the bad. He notes something is always coming up. Leadership requires the ability to adapt to challenges while compartmentalizing. John Boyd: Achiever, Investigator, Challenger; could not align with the military hierarchy but developed an innovative systematic perspective which his supporters championed and politicians leveraged. John Adair developed a modern leadership methodology based on the three-circles model. hope cooperation
can preserve the power of last resort antibiotics: Carbapenems are a class of beta-lactam antibiotics with a broad spectrum of antibacterial activity. Some bacteria (such as CRE) have developed resistance due to the development and r-factor distribution of carbapenemases. This is a huge problem as carbapenems have been used as the last resort antibiotic. , Colistin is an old antibiotic that is held in reserve in the US to treat especially dangerous infections (CREs) that are resistant to carbapenems. (Oct
2016). Worrying trends include: C. auris is a fungus resident in soils, which has developed resistance to medical antifungals: itraconazole; as well as azole agricultural fungicides. 90% of C. auris infections are resistant to an antifungal. 30% are resistant to two of the drugs. Genome analysis indicates four ancient strains persist. It has been assisted by the widespread use of fungicides enabling it to opportunistically migrate to niches cleared of its normal competitors. C. auris was first identified in an ear infection of a Japanese patient in 2009. But it had subsequently colonized all proximate surfaces and was detected in the air. It infects the very ill and those with weakened immune systems. 50% of those infected die within 90 days. resistance to
medical antifungals: itraconazole is an antifungal medication, classified by the WHO as an essential medicine. It is a triazole which stops fungal growth by undermining metabolism and cell membrane integrity. Effectiveness is being undermined by global agricultural deployment of equivalent azole fungicides on crops. ;
as well as azole agricultural fungicides (Apr
2019), CRE is carbapenem-resistant Enterobacteriaceae. When carbapenem fails to treat an infection the patient is in serious trouble. The CDC estimated CRE accounts for around 9,300 infections and 610 deaths yearly in the US in 2010-15. However the CDC also reports: - In July 2010 the state of Florida instigated procedures that reduced the number of patients with CRE from 60% to less than 10% at a problem LTCH. The improvement was based on
- Detecting and protecting - Screening, isolating, and grouping patients with CRE to prevent spread to other patients.
- Reviewing staff operations for 40 hours checking hand hygene, glove and gown use and other practices during care of patients.
- Iterative communications between the problem facility and local, state and federal public health workers.
(May
2016), C. diff usually competes with other bacteria in the human gut microbiome. But antibiotic treatments provide it with an advantage where it becomes the predominant gut bacteria causing diarrhea, abdominal pain, and toxic megacolon. Repeated treatments select for infections that are progressively more difficult to treat. C. difficile infections kill more than 25,000 people a year in the US. Fecal transplants, especially enabled by stool-banking, reintroduce competitive bacteria that limit the success of C. difficile and cure patients with previously recurrent infections. But the F.D.A. has not approved such transplants as a treatment and the procedure is not covered by insurance.
(May
2015), MDR is multidrug-resistant Tuberculosis (Vank's Disease). It is difficult to treat. Some of the medicines are intravenous, must be taken for two years (potentially just 9 months - Oct 2017) and can cause deafness, psychosis and kidney failure. Patients must be hospitalized and their movements restricted to one or two corridors, for months until they stop coughing live bacteria. & XDR is extensively drug-resistant tuberculosis. It requires very toxic and costly drugs to treat. Most patients die. TB, consumption or otherwise TB, is mostly an airborn bacterial lung infection, but it can also infect the brain, kidneys and other parts of the body. The only vaccine is still the BCG. The deployment of antibiotics during the 1940s allowed effective treatment: Streptomycin. In 1963 epidemiologist George Comstock realized why 30% of Alaskan adults were infected with TB - it grows slowly and is transmitted to other people before symptoms occur. Treatment was expanded to all contacts of a person with symptoms, who tested positive for TB. This strategy eradicated TB in the West, but was considered impractical in poor countries. Diagnostic tools for TB are insufficient. And because TB grows slowly in walled off pockets in the lungs it takes many months of treatment for antibiotics to eradicate the infection. TB benefits from compromised hosts and has benefited from HIV/AIDS. TB is also leveraging the plasmids that now carry immunity to all current antibiotics. In 2016 it is estimated to latently infect two billion people. 9.6 million worldwide became infected in 2014. 1.5 million people will die from TB in 2016. Deaths from the disease have fallen drastically since 2000. TB has been halted or reversed in 16 of the 22 countries: India (Sep 2016, Infection base estimate increased Oct 2016), Vietnam, Indonesia; that have the majority of cases. But it is still the infectious disease causing the most deaths world-wide. In 2018 W.H.O. asserts there is a $3.5 billion shortfall in funding for TB public health control efforts, a gap that will double by 2023. Nano scale drug delivery has the potential to push back on TB and is being actively researched (May 2016). ;
resulting in increased risk of sepsis is an infection triggered over-reaction by the immune system which causes general inflammation resulting in a cascade of problems: Blood clots, Leaky blood vessels; impeding blood flow to vital organs which can induce septic shock: Blood pressure drops, multiple organ failure, Heart damage and death. For every hour without antibiotics the probability of death increases 8%. Most cases start before people are hospitalized. People over 65, infants under 1 year, people with chronic diseases such as diabetes, or weakened immune systems and healthy people with incorrectly treated infections are most likely to contract sepsis. Most often the infections are of: lungs, urinary tract, skin, gut or intestines. Typically such infections were the result of a previous visit to a clinic or hospital. Symptoms of sepsis include: chills or fever, extreme pain or discomfort, clammy or sweaty skin, confusion or disorientation, shortness of breath and high heart rate. Dr. Diane Craig noted that sepsis had become the leading cause of death among hospitalized patients. Using patient matching on: age, symptoms, degree of illness; from the hospital system EHR, Craig identified the blood-lactate test as the key diagnostic that supported early, aggressive treatment of sepsis. She argued that whenever a patient had two symptoms of significant infection a lactate test be used along with EGDT treatment for patients with lactate counts as low as 2.5 millimoles/liter. This reduced sepsis mortality to 40% below the national average. But only half the hospitals in the US followed Craig's recommendations. Dr. Robert Pearl concludes this is because of the high risk of killing a patient with EGDT treatment, even though the protocol will reduce overall mortality by half. Doctors don't want to be responsible for killing patients so they opt not to order the lactate test. In 2017 sepsis is estimated to cost the US health care system more than $20 billion a year. The C.D.C. is concerned (Sep 2016) with antibiotic resistance generating more sepsis.

- Medicare is a social insurance program that guarantees access to health insurance for Americans aged 65 and over, and younger people with disabilities and end stage renal disease or ALS. Medicare is currently missing a cap on out-of-pocket costs and direct prescription drug coverage. It includes:
- Benefits
- Part A: Hospital inpatient insurance. As of Dec 2013 Medicare pays for home care in only limited circumstances, such as when a person needs temporary nursing care after a hospitalization. Part A covers 20 days of inpatient rehabilitation at a SNF after discharge from inpatient care at a hospital.
- Part B: Medical insurance for non-hospital services including: doctor visits, tests, injectable drugs, ambulances, physical therapy;
- Part C: Medicare Advantage
- Part D: indirect prescription drug coverage The MMA prohibits Medicare from directly negotiating drug prices.
- Eligibility
- All persons 65 years of age or older who are legal residents for at least 5 years. If they or a spouse have paid Medicare taxes for 10 years the Medicare part A payments are waived. Medicare is legislated to become the primary health plan.
- Persons under 65 with disabilities who receive SSDI.
- Persons with specific medical conditions:
- Have end stage renal disease or need a kidney transplant.
- They have ALS.
- Some beneficiaries are dual eligible.
- Part A requires the person has been admitted as an inpatient at a hospital. This is constrained by a rule that they stay for three days after admission.
- Sign-up
- Part A has automatic sign-up if the person is drawing social security. Otherwise the person must sign-up for Part A and Part B.
- Should sign-up for Part B during the Initial Enrollment Period, of seven months centered around 65th birthday, online or at a social security office. But if still covered by spouse's insurance or not yet retired then may only join during the 3 month general enrollment period (January to March) each year, with coverage initiated the following July. Incremental yearly 10% penalties apply for not signing up at 65. These penalties apply to all subsequent premiums.
- Premiums
- Part A premium
- Part B insurance premium
- Part C & D premiums are set by the commercial insurer.

- Impacting the microbiome, the trillions of bacteria and viruses that live inside higher animals' guts, on their skin etc. These bacteria and viruses seem to play a role in: immune responses, digesting food, making nutrients, controlling mental health and maintaining a healthy weight. The signals from the gut microbiota are relayed by major nerve fibers: vagus; to the central nervous system. The symbiotic relationship must be actively managed. Human armpits include glands which provide food favoring certain symbionts who build a defensive shield above the skin. In the human gut: Barriers are setup: Mucus secretions form a physical constraint and provide sites for bacteriophages to anchor and attack pathogenic bacteria; Symbiont tailored nourishment: Plant-heavy food creates opportunities for fibre specialists like Bacteroides thetaiotaomicron; is provided, Selective binding sites are provided, Poisons are deployed against the unwelcome, and Temperature, acidity and oxygenation are managed. High throughput sequencing allows the characterization of bacterial populations inside guts. Beginning at birth, as they pass down the birth canal infants are supplied with a microbiome from their mothers. If they are borne via cesarean they never receive some of the key bacteria: Bifidobaterium infantis which is also dependent on oligosaccharides in breast milk; from their mothers. A variety of diseases may be caused by changes in the microbiome:

- Associated with obesity is an addictive disorder where the brain is induced to require more eating, often because of limits to the number of fat cells available to report satiation (Jul 2016). Brain images of drug-addicted people and obese people have found similar changes in the brain. Obese people's reward network tends to be less responsive to dopamine and have a lower density of dopamine receptors. Obesity spreads like a virus through a social network with a 171% likelihood that a friend of someone who becomes obese will also become so. Obesity is associated with: metabolic syndrome including inflammation, cancer (Aug 2016), high cholesterol, hypertension, type-2-diabetes, asthma and heart disease. It is suspected that this is contributing to the increase in maternal deaths in the US (Sep 2016). Obesity is a complex condition best viewed as representing many different diseases, which is affected by the: Amount of brown adipose tissue (Oct 2016), Asprosin signalling by white adipose tissue (Nov 2016), Genetic alleles including 25 which guarantee an obese outcome, side effects of some pharmaceuticals for: Psychiatric disorders, Diabetes, Seizure, Hypertension, Auto-immunity; Acute diseases: Hypothyroidism, Cushing's syndrome, Hypothalamus disorders; State of the gut microbiome.

generated by the adaptive in evolutionary biology is a trait that increased the number of surviving offspring in an organism's ancestral lineage. Holland argues: complex adaptive systems (CAS) adapt due to the influence of schematic strings on agents. Evolution indicates fitness when an organism survives and reproduces. For his genetic algorithm, Holland separated the adaptive process into credit assignment and rule discovery. He assigned a strength to each of the rules (alternate hypothesis) used by his artificial agents, by credit assignment - each accepted message being paid for by the recipient, increasing the sender agent's rule's strength (implicit modeling) and reducing the recipient's. When an agent achieved an explicit goal they obtained a final reward. Rule discovery used the genetic algorithm to select strong rule schemas from a pair of agents to be included in the next generation, with crossing over and mutation applied, and the resulting schematic strategies used to replace weaker schemas. The crossing over genetic operator is unlikely to break up a short schematic sequence that provides a building block retained because of its 'fitness'; In Deacon's conception of evolution, an adaptation is the realization of a set of constraints on candidate mechanisms, and so long as these constraints are maintained, other features are arbitrary.
immune system has to support and protect an inventory of host cell types, detect and respond to invaders and maintain the symbiont equilibrium within the microbiome. It detects microbes which have breached the secreted mucus barrier, driving them back and fortifying the barrier. It culls species within the microbiome that are expanding beyond requirements. It destroys invaders who make it into the internal transport networks. As part of its initialization it has immune cells which suppress the main system to allow the microbiome to bootstrap. The initial microbiome is tailored by the antibodies supplied from the mother's milk while breastfeeding. The immune system consists of two main parts the older non-adaptive part and the newer adaptive part. The adaptive part achieves this property by being schematically specified by DNA which is highly variable. By rapid reproduction the system recombines the DNA variable regions in vast numbers of offspring cells which once they have been shown not to attack the host cell lines are used as templates for interacting with any foreign body (antigen). When the immune cell's DNA hyper-variable regions are expressed as y-shaped antibody proteins they typically include some receptor like structures which match the surfaces of the typical antigen. Once the antibody becomes bound to the antigen the immune system cells can destroy the invader. 's plasma cells,
B lymphocytes are a type of leukocyte. They appear mainly in the lymphatic network. Their are various types: - B cells which make antibodies that bind to pathogens, and activate the complement system. When malignant these cells can produce multiple myeloma.

- T cells including CD4+ helper cells, Cytotoxic T cells, Gamma 5 T cells;
, to accurately
identify and neutralize pathogens such as bacteria and viruses is a relatively small capsule containing genetic material: RNA, DNA; which utilizes the cellular infrastructure of its target host to replicate its genetic material and operational proteins. David Quammen explains the four key challenges of viruses: Getting from one host to another, penetrating a cell within the host, commandeering the cell's infrastructure, escaping from the cell and organism; Single-stranded RNA viruses: Coronavirus, chickungunya, dengue, Ebola, Hantas, Hendra, Influenzas, Junin, Lassa, Machupo, Marburg, Measles, Mumps, Nipah, Rabies, Retrovirus (HIV), Rhinovirus, yellow fever; are subject to more mutation events than DNA viruses, but limits the size of the genetic string. Double stranded DNA viruses: baculoviruses, hepadnaviruses, Herpesviruses, iridoviruses, papillomavirses, poxviruses; can leverage relatively far larger genetic payloads. The relationship with the reservoir host is long-term, a parasitic or symbiotic relationship, developing over millions of years. But opportunistically, it may spillover into a secondary host, with the virus entering the host cell, leveraging the host infrastructure to replicate its self massively and then exiting the host cell by rupturing it and killing the organism. that exhibit a matching

It is used in the derivation of the Dirac equation, developed by Paul Dirac using only first derivatives, is a Lagrangian density formula where the photon emission is equated to the contributing: magnitude of the electric charge of the proton, the electromagnetic current of the proton and Dirac spinor of the photon; and to the contributing: magnitude of the electric charge of the proton with contributing: ubar of the proton, Dirac matrix, Dirac spinor of the proton; and the Dirac spinor of the photon. Dirac took the square root of the relativistic energy-mass equation generating four partial differential equations involving four 4*4 matrices and a new four-component wave function which was soon understood to be a bispinor consisting of two Weyl-like spinors one for electrons and the other for the positron (anti-electron).

- Antihypertensives are
treatments for hypertension is high blood pressure. It is directly associated with death rate due to pressure induced damage to the left ventricle and in general to cardiovascular diseases. Treated with antihypertensives: Diuretics, Calcium channel blockers, Angiotensin receptor blockers or Beta blockers.
including: diuretics increase water excretion which results in reduced blood volume and pressure. Many work by making the kidneys transport more sodium into the urine. The sodium pulls water from the blood with it. The reduced fluid level in the blood vessels reduces the pressure on the walls of the arteries. , ACE inhibitors is angiotensin-converting-enzyme inhibitor. They help relax blood vessels and are used to treat hypertension and CHF. , calcium channel
blockers make blood vessels expand. They have four main effects:
- Reduce contraction of arteries by blocking calcium gates in vascular smooth muscle.
- By blocking calcium gates in cardiac muscle they reduce the force of contraction of the heart.
- By slowing the conduction of electrical flows within the heart they slow the heart beat.
- By blocking the calcium signal on adrenal cortex cells, they directly reduce aldosterone production reducing blood pressure.
, beta blockers stop the action of beta-adrenergic signals and hence slow the heart.
and angiotensin
antagonists block hormone signals (angiotensin II) from causing the contraction of muscles surrounding blood vessels and so stop the blood vessels contracting, lowering blood pressure. .

- Anxiety
is manifested in the amygdala contains > 12 distinct areas: Central, Lateral. It receives simple signals from the lower parts of the brain: pain from the PAG; and abstract complex information from the highest areas: Disgust, heart rate, and suffering from the insula cortex, allowing it to orchestrate emotion. It connects strongly to attention focusing networks. It sends signals to almost every other part of the brain, including to the decision making circuitry of the frontal lobes. It has high levels of D(1) dopamine receptors. During extreme fear the amygdala drives the hippocampus into fear learning. It outputs directly to subcortical reflexive motor pathways when speed is required. Its central nucleus projects to the BNST. It signals the locus ceruleus. It directly signals area 25. The amygdala:
- Promotes aggression. Stimulating the amygdala promotes rage. It converts anger into aggression and when impaired it impacts the ability to detect angry facial expressions.
- Participates in disgust
- Perceives fear promoting stimuli, focusing our attention on these. In PTSD sufferers the Amygdala overreacts to mildly fearful stimuli and is slow to calm down and the amygdala expands in size over a period of months. Fear is processed by the lateral nucleus which serves as the input from various senses, and the central nucleus which outputs to the brain stem (central grey - freezing, lateral hypothalamus - blood pressure, activates paraventricular hypothalamus => crf -> hormone adjustments).
- Has lots of receptors for and is highly sensitive to glucocorticoids. Stress inhibits the GABA interneurons in the basolateral amygdala (BLA) allowing the excitatory glutamate releasing neurons to excite more.
- Is sensitive to unsettling/uncertain social situations where it promotes anxiety and makes us distracted. It is also interested in uncertain but potentially painful situations. The amygdala contributes to social and emotional decision making where the BLA supports rejecting an unacceptable offer, as allowed in the Ultimatum Game, by injecting implicit mistrust and vigilance, generating an anger driven rejection that is used as punishment. The amygdala is very rapidly excited by subliminal signals from the thalamus of outgroup skin color. The amygdala subsequently tips social emotions against outgroups unless restrained by the frontal lobe or influenced by subliminal priming to prioritize inclusion. The fast path from the thalamus rapidly but inaccurately signals its identified a weapon.
- Sees suffering of others as increasingly salient with loving-kindness meditation practice, Goleman & Davidson explain.
- Promotes male, but not female, sexual motivation when it is an uncertain potential pleasure.
- Responds to the longing for uncertain potential pleasures and fear that the reward will not be worth it if it happens. The amygdala turns off during orgasm.
- Uses but is not directly involved in vision.
mediating inhibition of dopamine is a synaptic signal supporting generalized goal-directed behavior & anticipation of reward. Its significance is that the receptors that detect the signal are of the slow acting type and are used to alter (modulate) the response of fast acting dopaminergic neural circuits in which the receptors are deployed (LTP). The signal detects significant changes including predictions of models and actual results which differ unexpectedly. Dopamine is released primarily by neurons of the ventral tegmental area and the substantia nigra. The dopamine network architecture is designed to signal the possibility of any type of reward: Norm violation punishment, Winning a lottery, & Misfortune of an envied competitor. Dopamine signalling: - Rescales continuously to accommodate the range of intensity offered by different stimuli. So dopamine's responses to any reward habituate. GABA is released by some tegmental neurons to induce habituation. This allows addictions to develop.
- Reflects the anticipation of reward. It supports establishment of a relationship between a signal, working for a reward and obtaining the reward, but subsequently dopamine is mainly released encouraging the work, right after the signal supporting anticipation of the reward. Anticipation requires learning and is reflected in hippocampus activity. That explains context dependent cravings. And the learning architecture means reliable cues become rewarding. The accumbens supports willpower. And dopamine
- Promotes goal-oriented behavior needed to obtain & likely to achieve the reward - through the dopamine projections to the prefrontal cortex. That makes dopamine central to:
- Motivation. This binding fails in depression - due to stress and in anxiety - due to signals from the amygdala.
- The prefrontal cortex's mesocortically stimulated support for willpower to act to delay rewards. To sustain work for delayed rewards additional dopamine is released based on the length of the delay and the rewards uncertainty (modelled in the dorsolateral prefrontal cortex - which promotes the long term and the ventromedial prefrontal cortex - which promotes the short term) and the anticipated size of the reward (modelled in the accumbens). Impulsiveness in ADHD is reflected in abnormal dopamine processing. Addictive drugs bias the dopamine network towards impulsiveness.
- Is lowered by certain gene variants which induce: less dopamine in the synapse, fewer receptors, lower responsiveness of receptors; associated with (as tiny effects in hugely varying social scenarios): sensation seeking, risk taking, attentional problems, extroversion; where:
- The receptor D4's gene shows high variability. The D47R form is relatively unresponsive to dopamine.
- Dopamine is degraded by COMT. The COMT gene includes a variant which is highly efficient reducing dopamine signalling but with complicating gene/environment interactions.
- Dopamine is removed from the synapse by a reuptake transporter DAT.
rewards. Anxiety disorders are now seen as a related
cluster, including PTSD is post-traumatic stress disorder, an induced level of stress that is so troubling to the brain that it avoids processing it, change that is necessary if the stress is to be dissipated by the normal brain processes. The hippocampus loses volume. The damage to the hippocampus results in: flashbacks, becoming emotionally numb and withdrawn from other people, irritability, jumpiness, being more aggressive, having trouble sleeping and avoidance of the sensory experiences associated with the initial event. The amygdala responds to overwhelming trauma by repeatedly grabbing attention to encourage response to the emergency, increases in volume and is hyperactive and anxious. As a result it remains in a heightened state, resulting in fear of recall and further stress. PTSD is often accompanied by depression and substance abuse. It is now being realized that PTSD can be introduced into patients by traumatic treatment regimens such as ICU procedures. Traumatic head injuries, seen in athletes and soldiers can be reflected in PTSD and can subsequently become associated with prion based dementia. Some people are genetically predisposed to PTSD, with identical twins responding similarly. Another risk factor for PTSD is childhood trauma which can induce epi-genetic changes to stress processing. PTSD can be managed with CBT, and it also responds to propranolol while recalling the traumatic event, where the drug undermines the memory reconsolidation process. , panic
attacks, and phobias are innate fears with a predisposition encoded genetically in the central amygdala that have become learned fears in the BLA and have not been subsequently deprioritized by the frontal cortex. . Major
anxiety, is typically episodic, correlated with increased
activity in the amygdala, results in elevated glucocorticoids are corticosteroids which bind the glucocorticoid receptor. They decrease excitability of prefrontal cortical neurons. They have adverse effects in fetal/infant development having organizational effects on fetal brain construction and decreasing levels of: growth factors, neurons, synapses; resulting in an adult brain that is more sensitive to environmental triggers of depression and anxiety. Glucocorticoids affect gene control structures and induce epi-genetic changes. They have been found associated with high sodium chloride consumption (May 2017). and reduces
hippocampal is a part of the medial temporal lobe of the brain involved in the temporary storage or coding of long-term episodic memory. It includes the dentate gyrus. Memory formation in the cells of the hippocampus uses the MAP kinase signalling network which is impacted by sleep deprivation. The hippocampus dependent memory system is directly affected by cholinergic changes throughout the wake-sleep cycle. Increased acetylcholine during REM sleep promotes information attained during wakefulness to be stored in the hippocampus by suppressing previous excitatory connections while facilitating encoding without interference from previously stored information. During slow-wave sleep low levels of acetylcholine cause the release of the suppression and allow for spontaneous recovery of hippocampal neurons resulting in memory consolidation. It was initially associated with memory formation by McGill University's Dr. Brenda Milner, via studies of 'HM' Henry Molaison, whose medial temporal lobes had been surgically destroyed leaving him unable to create new explicit memories. The size of neurons' dendritic trees expands and contracts over a female rat's ovulatory cycle, with the peak in size and cognitive skills at the estrogen high point. Adult neurogenesis occurs in the hippocampus (3% of neurons are replaced each month) where the new neurons integrate into preexisting circuits. It is enhanced by learning, exercise, estrogen, antidepressants, environmental enrichment, and brain injury and inhibited by various stressors explains Sapolsky. Prolonged stress makes the hippocampus atrophy. He notes the new neurons are essential for integrating new information into preexisting schemas -- learning that two things you thought were the same are actually different. Specific cells within the hippocampus and its gateway, the entorhinal cortex, are compromised by Alzheimer's disease. It directly signals area 25. dendrite &
spine density. Some estrogen is a generic term for a number of related steroid hormones each of which works differently. Estrogen: - Is generated in the ovaries. It supports the generation of oxytocin, and so is associated with attachment, nurturing and other affiliative behaviors.
- Supports verbal memory. Removal of ovaries without immediate estrogen replacement therapy degrades verbal memory performance. The HT reduces age-related shrinkage of the PFC, parietal cortex, and temporal lobe in women, and made them less depressed and angry.
- Supports mitochondrial operation in the blood vessels of the brain.
- Contributes to maternal aggression but it can reduce aggression and enhance empathy, depending on brain state. There are two different estrogen receptor types which mediate these conflicting effects. The level of each type of receptor is independently regulated. Different receptor variants are associated with:
- Higher rates of anxiety among women
- Higher rates of antisocial behavior and conduct disorder in men
- Is essential for vaginal lubrication
- Facilitates the elimination of cholesterol
- Has anti-inflammatory and anti-oxidative properties improving response to stress
receptor, in biological cells these proteins are able to span the cell membrane and present an active site which is tailored to interact with a specific signal. When the receptor pairs with its signal, its overall shape changes resulting in changes in the part internal to the cell which can be relayed by the cells signalling infrastructure. In neuron synapses one type of receptor (fast) is associated with an ion channel. The other (slow) is associated with a signalling enzyme chain and modulates the neuron's response. variants are associated
with anxiety in women. Women are four times more
likely to suffer from anxiety. Louann
Brizendine concludes
this helps prepare mothers, so they are ready to protect
their children. Michael Pollan concludes anxiety is fear is an emotion which prepares the body for time sensitive action: Blood is sent to the muscles from the gut and skin, Adrenalin is released stimulating: Fuel to be released from the liver, Blood is encouraged to clot, and Face is wide-eyed and fearful. The short-term high priority goal, experienced as a sense of urgency, is to flee, fight or deflect the danger. There are both 'innate' - really high priority learning - which are mediated by the central amygdala and learned fears which are mediated by the BLA which learns to fear a stimulus and then signals the central amygdala. Tara Brach notes we experience fear as a painfully constricted throat, chest and belly, and racing heart. The mind can build stories of the future which include fearful situations making us anxious about current ideas and actions that we associate with the potential future scenario. And it can associate traumatic events from early childhood with our being at fault. Consequent assumptions of our being unworthy can result in shame and fear of losing friendships. The mechanism for human fear was significantly evolved to protect us in the African savanna. This does not align perfectly with our needs in current environments: U.S. Grant was unusually un-afraid of the noise or risk of guns and trusted his horses' judgment, which mostly benefited his agency as a modern soldier. of the future. Sufferers of
mild autism is a major hereditary mental disorder that starts before age three when it features: a strong preference to be alone, a desire for things to stay the same, and areas of creative ability - they see the ordinary as beautiful and have special talents for: poetry, foreign languages, music, art, and calculations. They generate less but more original ideas. It occurs as a spectrum of symptoms, from mild to severe, across the population of sufferers (ASD). Before age two the circumference of an autistic child's head is larger than typical and regions: amygdala, frontal lobe; develop prematurely, altering activity in other regions. Autism highlights aspects of the brain's specialized regions and processes for interacting with other people. Autistic's interests are restricted. They struggle with social interactions & verbal and nonverbal communications. Autistics do not attribute minds to other people: attributing mental states to others allows us to predict their behavior; a critical skill for social learning and interaction. While their visual area MT detects motion, the superior temporal sulcus does not respond to biological motion in autistics, undermining the understanding of intention. And they gaze at mouths rather than eyes when looking at faces. The default mode network is disrupted. Autistic adolescents have unusually large numbers of synapses, because of a failure of synaptic pruning. Autistics almost never pretend. They can't explain the difference between an instance of an object and a memory of it. Mild autism still maintains some pressure to conform socially and often results in depression and anxiety. Autism occurs in every country and social class. It lasts a lifetime. It has genetic and neurological causes. Identical twins are 90% likely to both have autism if one of them does. With 50% of genes active in the brain, mutations are likely to impact the development and operation of the brain. The genes: SHANK3, CDH10; are involved but account for a very small percentage of the risk. Facial gaze studies indicate a high genetic influence and an opportunity to identify more genes associated with autism (Jul 2017). Copy number variations: an extra copy of a segment of 25 genes of chromosome 7 increases the risk of ASD, while deletion of the segment causes Williams syndrome; and de novo mutations which drive up the number of autism cases as paternal age has increased in the US. ASD is associated with a reduced fusiform face area response. Tests [in development] for autism include: SynapDx's blood test. often develop anxiety

70% of people with generalized anxiety respond to drugs
increasing serotonin is a neurotransmitter. it is: - Inversely associated with: human impulsive, cricket, mollusk, crustacean; aggression. Low levels of serotonin are associated with impulsive aggression ranging from psychological measures of hostility to overt violence and cognitive impulsivity and impulsive suicide.
- Nearly all synthesized in the Raphe nucleus. Tryptophan hydroxylase makes serotonin from the amino-acid tryptophan. Monoamine oxidase degrades serotonin. The serotonin receptor binds serotonin to initiate cross membrane signalling. The serotonin transporter actively removes serotonin from synapses. Serotonin levels can be increased with: exercise, high light levels, consumption of chickpeas and traditional lime boiled corn tortillas. Reuptake is inhibited by SSRIs. Variants of the genes coding for these various enzymes alter the strength of their effects.
- Increasing serotonin signalling does not lessen impulsiveness in normal subjects but did in those prone to impulsivity. However, such experiments are fraught with complexity:
- Transient changes induced by drugs may adjust the immediate levels of serotonin but may not demonstrate structural effects.
- Gene variants likely produce structural changes in the developing brain.
- Effects monitored in experiments are often tiny.
- Behavioral changes: Violence, Arson, Exhibitionism; seen in different test subjects may be difficult to compare.
- Monoamine oxidase has high gene/environment interactions undermining heritability estimates. Its gene promotor is regulated by stress and glucocorticoids. So non genetic factors such as childhood adversity and adult provocation appear to be significant.

guilt is an emotion which alerts us to the risk of cheating on a friend. To be culturally effective the individuals must have respect for the law. Guilt is associated with activation of the posterior cingulate cortex. ; linked to depression is a debilitating episodic state of extreme sadness, typically beginning in late teens or early twenties. This is accompanied by a lack of energy and emotion, which is facilitated by genetic predisposition - for example genes coding for relatively low serotonin levels, estrogen sensitive CREB-1 gene which increases women's incidence of depression at puberty; and an accumulation of traumatic events. There is a significant risk of suicide: depression is involved in 50% of the 43,000 suicides in the US, and 15% of people with depression commit suicide. Depression is the primary cause of disability with about 20 million Americans impacted by depression at any time. There is evidence of shifts in the sleep/wake cycle in affected individuals (Dec 2015). The affected person will experience a pathological sense of loss of control, prolonged sadness with feelings of hopelessness, helplessness & worthlessness, irritability, sleep disturbances, loss of appetite, and inability to experience pleasure. Michael Pollan concludes depression is fear of the past. It affects 12% of men and 20% of women. It appears to be associated with androgen deprivation therapy treatment for prostate cancer (Apr 2016). Chronic stress depletes the nucleus accumbens of dopamine, biasing humans towards depression. Depression easily leads to following unhealthy pathways: drinking, overeating; which increase the risk of heart disease. It has been associated with an aging related B12 deficiency (Sep 2016). During depression, stress mediates inhibition of dopamine signalling. Both depression and stress activate the adrenal glands' release of cortisol, which will, over the long term, impact the PFC. There is an association between depression and additional brain regions: Enlarged & more active amygdala, Hippocampal dendrite and spine number reductions & in longer bouts hippocampal volume reductions and memory problems, Dorsal raphe nucleus linked to loneliness, Defective functioning of the hypothalamus undermining appetite and sex drive, Abnormalities of the ACC. Mayberg notes ACC area 25: serotonin transporters are particularly active in depressed people and lower the serotonin in area 25 impacting the emotion circuit it hubs, inducing bodily sensations that patients can't place or consciously do anything about; and right anterior insula: which normally generates emotions from internal feelings instead feel dead inside; are critical in depression. Childhood adversity can increase depression risk by linking recollections of uncontrollable situations to overgeneralizations that life will always be terrible and uncontrollable. Sufferers of mild autism often develop depression. Treatments include: CBT which works well for cases with below average activity of the right anterior insula (mild and moderate depression), UMHS depression management, deep-brain stimulation of the anterior insula to slow firing of area 25. Drug treatments are required for cases with above average activity of the right anterior insula. As of 2010 drug treatments: SSRIs (Prozac), MAO, monoamine reuptake inhibitors; take weeks to facilitate a response & many patients do not respond to the first drug applied, often prolonging the agony. By 2018, Kandel notes, Ketamine is being tested as a short term treatment, as it acts much faster, reversing the effect of cortisol in stimulating glutamate signalling, and because it reverses the atrophy induced by chronic stress. Genomic predictions of which treatment will be effective have not been possible because: Not all clinical depressions are the same, a standard definition of drug response is difficult;, which are treated

respond better to psychotherapy is a treatment for psychiatric illnesses, using verbal signals exchanged between the patient and therapist within a supportive relationship. There are various approaches: - Psychoanalysis, intially developed by Josef Breuer, where he applied free association. Freud adopted the technique. He applied it to his patients, concluding their problems originated in infancy and early childhood. He observed:
- Children have sexual and aggressive behavioral instincts which
- The children suppress the socially unacceptible thoughts into their unconscious. The suppressed thoughts can result in illness as the children grow into adults. Free association can reveal the supressed ideas.
- The patient develops a relationship, transference, with the therapist where their early relationships are reenacted. Freud's analysis of his depressed patients suggested they had been in a hostile relationship. Freud concluded this anger resulted in feelings of unworthyness and low self-esteem.
- CBT developed by University of Pennsylvania's Aaron Beck, whose depressed patients were not hostile to others, but consistently rated themselves as losers, having unrealistically high expectations of themselves, and struggled with disappointment.
:
psychoanalysis, and intensive CBT is cognitive behavioral therapy. It was originally designed to treat depression. Depressed patients demonstrated problems with how they perceived themselves in the world (cognitive style). Aaron Beck proposed to identify their negative beliefs and then replace them with more positive thoughts. CBT leverages cognitive and behavioral principles to cope with behaviors, induced by prior conditioning, which cannot be managed directly with rational thoughts. Instead it assumes that one's relationship with maladaptive thinking and emotional bindings can be changed through antecedent strategies. CBT is problem focused and action oriented. Errors in thinking like: overgeneralizing, magnifying negatives, minimizing positives and catastrophizing are replaced with more realistic and effective thoughts. CBT has been extended with prolonged exposure therapy and virtual reality exposure therapy, which have been used to treat PTSD, where the BLA learns the signals are no longer dangerous. .

refuge is a Buddhist practice used to develop a mental model of safety and belonging. Tara Brach explains there are three fundamental refuges: the Buddha, the dharma, and the sangha. Each person can approach the refuges in a way that is sincere for them: - Buddha refuge can represent the way Siddhartha Gautama coped with his fears of the terrible Mara: meeting it with his full attention, and observing and welcoming it, rather than responding to the feelings emotionally. And the devotional can seek safety in the living spirit of the Buddha's awakened heart and mind.
- Dharma refuge depends on realizing that everything in nature must change. Buddhists can call upon the practices and teachings; they have developed over centuries, which highlight this truth. And they can take refuge in these skills. Lovingkindness mediation can be particularly helpful practices in fearful situations.
- Sangha refuge is the community of monks and nuns that are also practicing and taking refuge.

is alternative payment model, Medicare is a social insurance program that guarantees access to health insurance for Americans aged 65 and over, and younger people with disabilities and end stage renal disease or ALS. Medicare is currently missing a cap on out-of-pocket costs and direct prescription drug coverage. It includes:
- Benefits
- Part A: Hospital inpatient insurance. As of Dec 2013 Medicare pays for home care in only limited circumstances, such as when a person needs temporary nursing care after a hospitalization. Part A covers 20 days of inpatient rehabilitation at a SNF after discharge from inpatient care at a hospital.
- Part B: Medical insurance for non-hospital services including: doctor visits, tests, injectable drugs, ambulances, physical therapy;
- Part C: Medicare Advantage
- Part D: indirect prescription drug coverage The MMA prohibits Medicare from directly negotiating drug prices.
- Eligibility
- All persons 65 years of age or older who are legal residents for at least 5 years. If they or a spouse have paid Medicare taxes for 10 years the Medicare part A payments are waived. Medicare is legislated to become the primary health plan.
- Persons under 65 with disabilities who receive SSDI.
- Persons with specific medical conditions:
- Have end stage renal disease or need a kidney transplant.
- They have ALS.
- Some beneficiaries are dual eligible.
- Part A requires the person has been admitted as an inpatient at a hospital. This is constrained by a rule that they stay for three days after admission.
- Sign-up
- Part A has automatic sign-up if the person is drawing social security. Otherwise the person must sign-up for Part A and Part B.
- Should sign-up for Part B during the Initial Enrollment Period, of seven months centered around 65th birthday, online or at a social security office. But if still covered by spouse's insurance or not yet retired then may only join during the 3 month general enrollment period (January to March) each year, with coverage initiated the following July. Incremental yearly 10% penalties apply for not signing up at 65. These penalties apply to all subsequent premiums.
- Premiums
- Part A premium
- Part B insurance premium
- Part C & D premiums are set by the commercial insurer.

risk based payments to organizations set up as ACO is an Accountable Care Organization. These are accredited bundles of companies which together try to offer Dartmouth-Hitchcock like business models (Dec 2015, Sep 2016) focused on wellness, improving the provision of primary care to a large group of Medicare patients, and rewarding doctors for preventing problems. Advocate health illustrates the idea. Robert Pearl notes that the transition is difficult: hospitals that find their efficiency improving should reduce the number of doctors they utilize. But any doctors that are pushed out of the ACO will likely take their patients with them, undermining the revenues that support the FFV business. The ACA regulates qualification to be a Medicare ACO. Individual organizations within a Medicare shared savings ACO continue to submit their own claims and are paid by Medicare for FFS. But the ACO is eligible for shared savings. Within the shared savings program the CMS innovation center has setup advanced payment ACOs. As an alternative to shared savings, in a Pioneer ACO, over time 50% of the FFS payments flow directly to the ACO as a bundled payment. CMS has established quality measures for ACOs for Medicare. The CMS program's purpose is to reward providers for reducing total cost of care for patients through prevention, disease management, and coordination. - CMS initiated its Physician Group Practice Demonstration in 2005. By 2008 the congressional budget office reported on Bonus-eligible organizations.
- CMS defines ACOs as organizations that "create incentives for health care providers to work together to treat an individual patient across care settings - including doctors' offices, hospitals and long-term care facilities."
- CMS has developed APMs which include ACOs, and advanced APMs where the ACOs must be risk bearing.
- CMMI accepts providers' proposals to test various payment systems including shared savings and partial capitation.
- Private market ACOs have formed including: Providence Health & Services, Blue Shield California, Anthem Blue Cross, United Health Care, BCBS Minnesota, BCBS Illinois, Humana, CIGNA, Main Health Management Coalition, BCBS Massachusetts, Aetna.

late-onset sporadic Alzheimer's
disease is a dementia which correlates with deposition of amyloid plaques in the neurons. As of 2015 there are 5 million Alzheimer's patients in the USA. It was originally defined as starting in middle age which is rare, so it was a rare dementia. But in 1980s it was redefined as any dementia without another known cause. Early indications include mood and behavioral changes (MBI) and declarative memory and thinking problems (MCI). Specific cells within the hippocampal circuitry and its gateway, the entorhinal cortex, are damaged. The amygdala, cerebelum and other areas supporting implicit memory are not impacted during the early stages of the disease. Grid cell destruction results in a sense of being lost. The default mode network is disrupted. Variants include: late-onset sporadic; with risk factors - ApoE4 for late onset Alzheimer's, presenilin, androgen deprivation therapy (Dec 2015), type 2 diabetes. There are multiple theories of the mechanism of Alzheimer's during aging: Allen Roses argues that it is due to gene alleles that limit the capacity of mitochondria to support neuron operation, Neurons of sporadic Alzheimer's sufferers show greater APP gene diversity due to somatic recombination; It may be initiated by: stress induced HHV-6a, HHV7 herpes activation (Jun 2018) and or an increasingly leaky blood-brain barrier; and a subsequent innate immune response to the infections (May 2016). The Alzheimer's pathway follows: - Plaques form. These are seen in fMRIs 10 to 15 years prior to detecting memory and thinking changes. APP deployed in the cell membrane is cut into three parts. The external part becomes amyloid-beta peptide which aggregates into Amyloid plaques, external to the neurons, if too much is generated or it is not removed fast enough.
- Solanezumab aimed to inhibit plaque formation but clinical trials failed (Nov 2016).
- Encouraging the garbage collection of amyloid and tau with gamma rhythms stimulation retards Alzheimer's in mice studies (Mar 2019)
- BACE inhibitors block an enzyme needed to form amyloid.
- Mutation driven misfolded Tau proteins can form tangles within the cytoplasm of neurons. The Tau tangles kill nerve cells. LMTX is a drug treatment targeted at these tangles.
- The brain becomes inflamed resulting in the killing of many more nerve cells. The hippocampus disintegrates and the brain loses critical functions and memory loss becomes noticeable.

programmed cell death is a signal, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy.
initiated DNA (DNA), a polymer composed of a chain of deoxy ribose sugars with purine or pyrimidine side chains. DNA naturally forms into helical pairs with the side chains stacked in the center of the helix. It is a natural form of schematic string. The purines and pyrimidines couple so that AT and GC pairs make up the stackable items. A code of triplets of base pairs (enabling 64 separate items to be named) has evolved which now redundantly represents each of the 20 amino-acids that are deployed into proteins, along with triplets representing the termination sequence. Chemical modifications and histone binding (chromatin) allow cells to represent state directly on the DNA schema. To cope with inconsistencies in the cell wide state second messenger and evolved amplification strategies are used. controlled process

is an emotion are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism.

the benefit to hunter-gatherers is a lifestyle organized around a band of relatives, evolved in humans focused on capturing the cognitive niche in the African savanna. It is of great significance in shaping our minds: behaviors, emotions, creativity, intelligence; and developing survival strategies including use of fire and language, according to evolutionary psychologists. It was practiced by all humans, for most of Homo sapiens existence, until the emergence of farming, and still is by some isolated bands: Ju/'hoansi, New Guinea: Gebusi, Mae Enga; & Borneo head hunters, Maasai & Zulu warriors from Africa, Amazonians: Waorani, Jivaro; Brazilian and Venezuelan Yanomamo. Since the band moves on when it has depleted the resources in an area of land, the soil remains vibrant, but the large animals were typically placed in a position of stress from which they did not recover.

generating serotonin is a neurotransmitter. it is: - Inversely associated with: human impulsive, cricket, mollusk, crustacean; aggression. Low levels of serotonin are associated with impulsive aggression ranging from psychological measures of hostility to overt violence and cognitive impulsivity and impulsive suicide.
- Nearly all synthesized in the Raphe nucleus. Tryptophan hydroxylase makes serotonin from the amino-acid tryptophan. Monoamine oxidase degrades serotonin. The serotonin receptor binds serotonin to initiate cross membrane signalling. The serotonin transporter actively removes serotonin from synapses. Serotonin levels can be increased with: exercise, high light levels, consumption of chickpeas and traditional lime boiled corn tortillas. Reuptake is inhibited by SSRIs. Variants of the genes coding for these various enzymes alter the strength of their effects.
- Increasing serotonin signalling does not lessen impulsiveness in normal subjects but did in those prone to impulsivity. However, such experiments are fraught with complexity:
- Transient changes induced by drugs may adjust the immediate levels of serotonin but may not demonstrate structural effects.
- Gene variants likely produce structural changes in the developing brain.
- Effects monitored in experiments are often tiny.
- Behavioral changes: Violence, Arson, Exhibitionism; seen in different test subjects may be difficult to compare.
- Monoamine oxidase has high gene/environment interactions undermining heritability estimates. Its gene promotor is regulated by stress and glucocorticoids. So non genetic factors such as childhood adversity and adult provocation appear to be significant.

network with: amydala contains > 12 distinct areas: Central, Lateral. It receives simple signals from the lower parts of the brain: pain from the PAG; and abstract complex information from the highest areas: Disgust, heart rate, and suffering from the insula cortex, allowing it to orchestrate emotion. It connects strongly to attention focusing networks. It sends signals to almost every other part of the brain, including to the decision making circuitry of the frontal lobes. It has high levels of D(1) dopamine receptors. During extreme fear the amygdala drives the hippocampus into fear learning. It outputs directly to subcortical reflexive motor pathways when speed is required. Its central nucleus projects to the BNST. It signals the locus ceruleus. It directly signals area 25. The amygdala: - Promotes aggression. Stimulating the amygdala promotes rage. It converts anger into aggression and when impaired it impacts the ability to detect angry facial expressions.
- Participates in disgust
- Perceives fear promoting stimuli, focusing our attention on these. In PTSD sufferers the Amygdala overreacts to mildly fearful stimuli and is slow to calm down and the amygdala expands in size over a period of months. Fear is processed by the lateral nucleus which serves as the input from various senses, and the central nucleus which outputs to the brain stem (central grey - freezing, lateral hypothalamus - blood pressure, activates paraventricular hypothalamus => crf -> hormone adjustments).
- Has lots of receptors for and is highly sensitive to glucocorticoids. Stress inhibits the GABA interneurons in the basolateral amygdala (BLA) allowing the excitatory glutamate releasing neurons to excite more.
- Is sensitive to unsettling/uncertain social situations where it promotes anxiety and makes us distracted. It is also interested in uncertain but potentially painful situations. The amygdala contributes to social and emotional decision making where the BLA supports rejecting an unacceptable offer, as allowed in the Ultimatum Game, by injecting implicit mistrust and vigilance, generating an anger driven rejection that is used as punishment. The amygdala is very rapidly excited by subliminal signals from the thalamus of outgroup skin color. The amygdala subsequently tips social emotions against outgroups unless restrained by the frontal lobe or influenced by subliminal priming to prioritize inclusion. The fast path from the thalamus rapidly but inaccurately signals its identified a weapon.
- Sees suffering of others as increasingly salient with loving-kindness meditation practice, Goleman & Davidson explain.
- Promotes male, but not female, sexual motivation when it is an uncertain potential pleasure.
- Responds to the longing for uncertain potential pleasures and fear that the reward will not be worth it if it happens. The amygdala turns off during orgasm.
- Uses but is not directly involved in vision.
, hypothalamus is essential to many instinctive operations of the body. It can be viewed as the executor of emotion: happiness, sadness, aggression, eroticism and mating, relaying the amygdala's responses to low level sensory signals. It has many small sub-regions whose main functions are to regulate hunger, thirst, temperature, sexual behavior, parenting, heart rate, blood pressure, sleep cycles, and similar body operations. Kandel notes it includes a nucleus containing two distinct populations of neurons: one that regulates aggression and one that regulates sex and mating. At the intersection neurons are active in both. Depending on the intensity of the stimulus applied to these neurons mating (weak) or aggression (danger) is activated. This probably contributes to sexual rage and is why some couples derive extra pleasure from sexual experiences following an argument. The hypothalamus's (paraventricular nucleus) is closely connected to the pituitary which secrets hormones into the bloodstream ( => acth -> adrenal cortex => cortisol (+)-> amygdala & (-)-> hippocampus). It directly signals area 25. , hippocampus is a part of the medial temporal lobe of the brain involved in the temporary storage or coding of long-term episodic memory. It includes the dentate gyrus. Memory formation in the cells of the hippocampus uses the MAP kinase signalling network which is impacted by sleep deprivation. The hippocampus dependent memory system is directly affected by cholinergic changes throughout the wake-sleep cycle. Increased acetylcholine during REM sleep promotes information attained during wakefulness to be stored in the hippocampus by suppressing previous excitatory connections while facilitating encoding without interference from previously stored information. During slow-wave sleep low levels of acetylcholine cause the release of the suppression and allow for spontaneous recovery of hippocampal neurons resulting in memory consolidation. It was initially associated with memory formation by McGill University's Dr. Brenda Milner, via studies of 'HM' Henry Molaison, whose medial temporal lobes had been surgically destroyed leaving him unable to create new explicit memories. The size of neurons' dendritic trees expands and contracts over a female rat's ovulatory cycle, with the peak in size and cognitive skills at the estrogen high point. Adult neurogenesis occurs in the hippocampus (3% of neurons are replaced each month) where the new neurons integrate into preexisting circuits. It is enhanced by learning, exercise, estrogen, antidepressants, environmental enrichment, and brain injury and inhibited by various stressors explains Sapolsky. Prolonged stress makes the hippocampus atrophy. He notes the new neurons are essential for integrating new information into preexisting schemas -- learning that two things you thought were the same are actually different. Specific cells within the hippocampus and its gateway, the entorhinal cortex, are compromised by Alzheimer's disease. It directly signals area 25. , insula cortex is part of the cerebral cortex folded deep within the lateral sulcus. It includes: anterior, posterior insula; and is overlaid by the operculum. Kandel notes the anterior insula is where feelings are calibrated by evaluating and integrating the importance of the stimuli. It directly signals area 25. LeDoux showed there are two routes for signals of feelings and emotions to the amygdala: a fast unconscious one and a slow one that involves the anterior insula. So the insula is assumed to participate in consciousness where it has been linked to emotion, salience & body homeostasis functions: - Perception,
- Motor control: Hand-&-eye motor movement, Swallowing, Gastric motility, Speech articulation;
- Self-awareness,
- Inter-personal experiences: Disgust at smells, contamination & mutilation which generate visceral responses, that are projected to the amygdala; binding physical and moral aspects of purity (Macbeth effect)
- Suffering of others can be projected by the insula to the amygdala and made increasingly salient with loving-kindness meditation practice, Goleman & Davidson explain.
- Homeostatic regulation of the sympathetic network, parasympathetic network, and immune system. Heart rate and sweat gland activity are monitored. When the amygdala signals concern, the insula prepares the body for action, increasing blood flow to the muscles etc.

therapy for H.I.V is human immunodeficiency virus, an RNA retrovirus which causes AIDS. It infects T-lymphocytes helper cells slowly destroying the host's immune system. The main pandemic form of HIV is HIV-1 M which has been traced back to a spillover to Cameroon/Congolese forest Chimpanzees of SIVs that weakly infected proximate humans and then was amplified by social conditions in expanding towns: Ouesso, Brazzaville, Leopoldville; down river from these forests during the 1900 - 1920s. Additional amplification occurred through public health programs: Trypanosomiasis, STDs; which cross-infected subpopulations of Leopoldville/Kinshasa around the same time. UNESCO organized Haitian support for the DRC in the 1960s vectored HIV-1 M back to Haiti where the blood plasma trade provided an evolved amplifier for HIV-1 M infected plasma to flow into the US healthcare supply chain through Miami.

which prevents the virus is a relatively small capsule containing genetic material: RNA, DNA; which utilizes the cellular infrastructure of its target host to replicate its genetic material and operational proteins. David Quammen explains the four key challenges of viruses: Getting from one host to another, penetrating a cell within the host, commandeering the cell's infrastructure, escaping from the cell and organism; Single-stranded RNA viruses: Coronavirus, chickungunya, dengue, Ebola, Hantas, Hendra, Influenzas, Junin, Lassa, Machupo, Marburg, Measles, Mumps, Nipah, Rabies, Retrovirus (HIV), Rhinovirus, yellow fever; are subject to more mutation events than DNA viruses, but limits the size of the genetic string. Double stranded DNA viruses: baculoviruses, hepadnaviruses, Herpesviruses, iridoviruses, papillomavirses, poxviruses; can leverage relatively far larger genetic payloads. The relationship with the reservoir host is long-term, a parasitic or symbiotic relationship, developing over millions of years. But opportunistically, it may spillover into a secondary host, with the virus entering the host cell, leveraging the host infrastructure to replicate its self massively and then exiting the host cell by rupturing it and killing the organism. from
replicating leaving it dormant so AIDS is acquired auto-immune deficiency syndrome, a pandemic disease caused by the HIV. It also amplifies the threat of tuberculosis. Initially deadly, infecting and destroying the T-lymphocytes of the immune system, it can now be treated with HAART to become a chronic disease. And with an understanding of HIV's mode of entry into the T-cells, through its binding to CCR5 and CD4 encoded transmembrane proteins, AIDS may be susceptible to treatment with recombinant DNA to alter the CCR5 binding site, or with drugs that bind to the CCR5 cell surface protein preventing binding by the virus. Future optimization of drug delivery may leverage nanoscale research (May 2016).

- ASD
is autism is a major hereditary mental disorder that starts before age three when it features: a strong preference to be alone, a desire for things to stay the same, and areas of creative ability - they see the ordinary as beautiful and have special talents for: poetry, foreign languages, music, art, and calculations. They generate less but more original ideas. It occurs as a spectrum of symptoms, from mild to severe, across the population of sufferers (ASD). Before age two the circumference of an autistic child's head is larger than typical and regions: amygdala, frontal lobe; develop prematurely, altering activity in other regions. Autism highlights aspects of the brain's specialized regions and processes for interacting with other people. Autistic's interests are restricted. They struggle with social interactions & verbal and nonverbal communications. Autistics do not attribute minds to other people: attributing mental states to others allows us to predict their behavior; a critical skill for social learning and interaction. While their visual area MT detects motion, the superior temporal sulcus does not respond to biological motion in autistics, undermining the understanding of intention. And they gaze at mouths rather than eyes when looking at faces. The default mode network is disrupted. Autistic adolescents have unusually large numbers of synapses, because of a failure of synaptic pruning. Autistics almost never pretend. They can't explain the difference between an instance of an object and a memory of it. Mild autism still maintains some pressure to conform socially and often results in depression and anxiety. Autism occurs in every country and social class. It lasts a lifetime. It has genetic and neurological causes. Identical twins are 90% likely to both have autism if one of them does. With 50% of genes active in the brain, mutations are likely to impact the development and operation of the brain. The genes: SHANK3, CDH10; are involved but account for a very small percentage of the risk. Facial gaze studies indicate a high genetic influence and an opportunity to identify more genes associated with autism (Jul 2017). Copy number variations: an extra copy of a segment of 25 genes of chromosome 7 increases the risk of ASD, while deletion of the segment causes Williams syndrome; and de novo mutations which drive up the number of autism cases as paternal age has increased in the US. ASD is associated with a reduced fusiform face area response. Tests [in development] for autism include: SynapDx's blood test.

All these disorders are characterized by difficulty
connecting with others. People who suffer from ASD
show a reduced fusiform is a region of the brain which supports advanced mechanisms of shape recognition and implements the early stages of reading. Subliminal priming with words did not depend on the shape of the word. The fusiform gyrus was able to process the abstract identity of a word without caring if it was upper or lower case. While high up in the cortex it can operate below the level of conscious experience. It contributes to social emotions with: - Its face area being more activated by faces with in-group skin color.
- It activating when shown pictures of cars in automobile aficionados.
- It activating when shown pictures of birds in birdwatchers; since it really recognizes examples of items from an individual's emotionally salient categories.
response to faces. ASD is linked to gene variants
affecting oxytocin is a peptide hormone which makes humans more prosocial to and socially competent in their in-group and more antisocial to everyone else. The effects are contingent; changing during stress and in the presence of a threatening out-group. Oxytocin makes people look at eyes longer, encouraging improved accuracy at perceiving emotions. It enhances activity in the TPJ supporting modeling of other people's thinking. Dogs and their owners secrete oxytocin increasing the amount of eye contact between them. It is associated with pair bonding. Brizendine explains that oxytocin and dopamine production are stimulated by ovarian estrogen at the onset of puberty, encouraging girls to connect and bond with their girlfriends, reducing stress, and exclude the out-group. It is central to female mammals wanting to nurse, nursing, and remembering their child. Its effects are context dependent and so is the regulation of the genes that control oxytocin. Variants of a gene CD38 which facilitates oxytocin secretion from neurons are associated with differing levels of activation of the fusiform face area when looking at faces. Sapolsky describes an oxytocin receptor gene variant that is associated with children showing: Extreme aggression, A callous unemotional style; foreshadowing adult psychopathy. And another receptor gene variant is associated with childhood social disconnection and unstable adult relationships. Gene/environment interactions complicate the interpretation of the presence of particular gene variants. Hypothalamic neurons send projections to: ventral tegmentum which also becomes more receptive during child birth, nucleus accumbens, hippocampus, amygdala where it inhibits the central amygdala suppressing fear & anxiety consistently in men while still allowing women to respond to threats to their infants, frontal cortex, olfactory network where it helps new rat mums to learn the smell of their offspring; where oxytocin prepares the brain for in-group bonding, out-grouping, birth and maternal behavior. Outside the brain hypothalamic neurons in females send oxytocin to the posterior pituitary where it enters the blood stream stimulating uterine contraction during labor & supporting milk production for weaning. Disorders associated with oxytocin abnormalities include ASD. and vasopressin developed by duplication and subsequent mutation of the vasotocin gene, along with oxytocin, during the initial formation of mammals. It acts as a hormone regulating water retention in the kidneys. It supports paternal behavior stimulated by a female giving birth. Sex releases vasopressin in the nucleus accumbens of male prairie voles. And prairie voles have more receptors in the accumbens than other voles supporting their pair bonding. This situation is similar in bonobos relative to chimps where it encourages social bonding - but not monogamy. Vasopressin is made in hypothalamic neurons which project to the posterior pituitary for release as a hormone. It is also a neuropeptide transmitting from hypothalamic projections to the ventral tegmentum, nucleus accumbens, hippocampus, amygdala, and frontal cortex. And it is made & secreted in other areas of the brain. Vasopressin enhances aggression in paternal prairie vole males. But the aggression is then maintained by social learning. , to nongenetic
mechanisms that silence the oxytocin receptor gene and to
lower levels of the receptor, in biological cells these proteins are able to span the cell membrane and present an active site which is tailored to interact with a specific signal. When the receptor pairs with its signal, its overall shape changes resulting in changes in the part internal to the cell which can be relayed by the cells signalling infrastructure. In neuron synapses one type of receptor (fast) is associated with an ion channel. The other (slow) is associated with a signalling enzyme chain and modulates the neuron's response.

There will also be somatic copies which are modified by the operational agents so that they can represent their current state. DNA (DNA), a polymer composed of a chain of deoxy ribose sugars with purine or pyrimidine side chains. DNA naturally forms into helical pairs with the side chains stacked in the center of the helix. It is a natural form of schematic string. The purines and pyrimidines couple so that AT and GC pairs make up the stackable items. A code of triplets of base pairs (enabling 64 separate items to be named) has evolved which now redundantly represents each of the 20 amino-acids that are deployed into proteins, along with triplets representing the termination sequence. Chemical modifications and histone binding (chromatin) allow cells to represent state directly on the DNA schema. To cope with inconsistencies in the cell wide state second messenger and evolved amplification strategies are used. , without any sexual sharing and

(acetylsalicylic acid) is a pain emerged as a mental experience, Damasio asserts, constructed by the mind using mapping structures and events provided by nervous systems. But feeling pain is supported by older biological functions that support homeostasis. These capabilities reflect the organism's underlying emotive processes that respond to wounds: antibacterial and analgesic chemical deployment, flinching and evading actions; that occur in organisms without nervous systems. Later in evolution, after organisms with nervous systems were able to map non-neural events, the components of this complex response were 'imageable'. Today, a wound induced by an internal disease is reported by old, unmyelinated C nerve fibers. A wound created by an external cut is signalled by evolutionarily recent myelinated fibers that result in a sharp well-localized report, that initially flows to the dorsal root ganglia, then to the spinal cord, where the signals are mixed within the dorsal and ventral horns, and then are transmitted to the brain stem nuclei, thalamus and cerebral cortex. The pain of a cut is located, but it is also felt through an emotive response that stops us in our tracks. Pain amplifies the aggression response of people by interoceptive signalling of brain regions providing social emotions including the PAG projecting to the amygdala; making aggressive people more so and less aggressive people less so. Fear of pain is a significant contributor to female anxiety. Pain is the main reason people visit the ED in the US. Pain is mediated by the thalamus and nucleus accumbens, unless undermined by sleep deprivation.

The inhibitors include: Low dose aspirin, Clopidogrel; . While its NNT is number needed to treat. Austin Frakt and Aaron Carroll explain in the NYT Upshot that it is a number that describes how many people must be treated for one to gain a benefit. For aspirin protection from heart attack it is about 2000. That means 2000 people taking aspirin for two years will result in 1 person not having a heart attack, while 3.6 will have a heart attack anyway, 1995.4 will never have heart attacks any way. But we don't know who the one person is and aspirin are cheap and don't have many side effects. The NNT for catching influenza is between 37 and 77. Since millions can catch flu, and thousands of those die the payoff of flu vaccination is huge. is 2000 for cardiovascular disease refers to: - Conditions where narrowed and blocked blood vessels result in angina, hypertension, CHD and heart attacks and hemorrhagic/ischemic strokes.

produced in white adipose tissue that signals, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy. the brain and liver is an emergent cellular system providing metabolic: Dietary compound metabolism and signalling: After gorging on sugar-rich foods the liver releases FGF21 hormone to dampen further eating activity; Detoxification, Regulation of glucose through glycogen storage (asprosin signalling from white adipose tissue); clotting, immune, exocrine and endocrine functions.

Federal Medicaid is the state-federal program for the poor. Originally part of Lyndon Johnson's 1965 Bill, eligibility and services vary by state. Medicaid currently pays less for care than Medicare, resulting in many care providers refusing to participate in the program. Less than 10 percent of Medicaid recipients, those in long-term care including nursing homes where 64% are dependent on Medicaid, use one-third of all Medicaid spending which is a problem. The ACA's Medicaid expansion program, made state optional by the SCOTUS decision, was initially taken up by fifty percent of states. As of 2016 it covers 70 million Americans at a federal cost of $350 billion a year. In 2017 it pays for 40% of new US births. does not

Brain images of drug-addicted people and obese people have found similar changes in the brain. Obese people's reward network tends to be less responsive to dopamine and have a lower density of dopamine receptors. Obesity spreads like a virus through a social network with a 171% likelihood that a friend of someone who becomes obese will also become so.

cytotoxic T-cells (immune checkpoint inhibition release the immune system's checkpoints: PD-1, CTLA-4; on attacking host cells: by 1) stopping T-cell division and 2) reducing their life spans. They are used in immuno-oncology where, in 2016: They are approved for treatment of: Advanced melanoma, HL, lung, kidney, liver cancer; They have a general success rate of 20 - 40% and higher for melanoma. Checkpoint inhibitors work best for tumors that have many mutations: melanomas, lung and bladder cancers. They are enhanced by adjunct treatments that kill tumor cells generating debris to stimulate the immune system. The drugs include: ipilimumab (CTLA-4 inhbition), nivolumab, pembrolizumab, atezolizumab (PD-1 inhibitors); They are costly and often have high copayments. They cause auto-immune side effects including inflammation, rheumatoid arthritis and damage to glands: Adrenal, Thyroid, Pituitary. Powerful steroids such as prednisone can help reduce the inflammation. Damaged glands require sustained hormone treatment. Checkpoint inhibitor research is funded by the CRI. ).
- Atherosclerosis is the thickening of an
artery wall due to invasion and accumulation of leukocytes are produced by hematopoietic stem cells in the bone marrow and are a major part of the adaptive immune system. Five types have been identified:
- Basophils,
- Eosinophils,
- Lymphocytes,
- Monocytes,
- Neutrophyls.
