Description of Physiology of the Stress Mechanism


The Stress-Response Cycle
The human stress-response cycle is a complex neuroendocrine response triggered by perceived or real threats from the environment or internal stimuli. The sympathetic nervous system and the hypothalamus-pituitary-adrenal (HPA) axis are primarily responsible for the
physiological changes associated with a stressful state (Selye, 1937).  The initial catecholamine response triggered from the sympathetic nervous system involves a rapid release of epinephrine and norepinephrine into the bloodstream and throughout the body, inducing the changes characteristic of the ‘fight or flight’ response—increased heart rate and respiration, pupil dilation, and more blood flow to the skeletal muscles, vigilance, and so forth…… Continue reading


Childhood Stress and Trauma Leads to External vs. Internal Focus


The Degree Of Early Life Stress Predicts …And The Shift From Internally To Externally Guided Decision Making:...Excerpted and edited from full article here

Take Aways:

Taken together, our neuronal and behavioral findings demonstrate that:

  • High childhood stress and trauma
  • Is related to lower MPFC activation during both rest and the self-oriented task.
  • This is behaviorally manifested as an abnormal shift from internally to externally guided decision making, even in situations where internal guidance is required.

Is Western/Affluent Diet Mainly Long-Term Poisonous?


“Western-Style” Diet Lowers the Odds of Ideal Aging

Western Style Diet May Lead to Greater Risk of Premature Death

A newly published study suggests that a “Western-style” diet reduces a person’s likelihood of achieving older ages in good health, finding that avoidance of the “Western-type foods” might actually improve the possibility of achieving older ages free of chronic diseases and remaining highly functional.

Doctors and Marketers Specialize in the Same Thing — Human Physiology


Doctors make decisions, somewhat, based on medical facts about how the body and it’s organs work — so should marketers and business people.

Like a doctor, marketers profession is understanding, explaining, predicting and influencing body physiology — specifically the organ of the brain as it determines behavior.

Subjective, everyday experiences and everyday/natural language is no more useful to a marketer than a doctor.

To understand and treat any medical conditions, reports about emotions and conscious perceptions are minimally informative and much more likely to be misinforming.  Why should it be any different for marketing and business?  Tests are the norm.  In fact, any doctor who depended on self-reports and everyday language would soon kill patients and be guilty of malpractice.

A bunch of people getting in a room and making decision based on swapping opinions, platitudes, case studies and the most powerful people, the clients (“patients”), is no more useful than using the same tactics to decide medical treatments. 

“…depressed people often have a relatively normal self-rated experience of encounters with pleasurable stimuli and that, over and above any problems with the experience of pleasure, depressed people appear to have impairments in behavioral activation, reward-seeking behavior, and exertion of effort. Indeed, most depressed people suffer from a crippling constellation of motivational impairments that include psychomotor retardation, anergia, and fatigue…”


Brain Disorders Causing Violence.


Persons committing murder and other forms of violent crime are likely to exhibit a personality disorder (PD) of one type or another. Essentially any personality disorder can be associated with violent crime, with the possible exception of avoidant PD. Continue reading
