HOW DOES IT GET UNDER THE SKIN? How environmental/external influences
translate into changes in a person's nervous system and ultimately their biology
Immediate reactions to environment This presentation will touch on
endocrine, limbic systems and spirituality

ENTERIC NERVOUS SYSTEM
Has some innervation from the ANS but also functions independently
Embedded in the lining of the GI tract Responsible for peristalsis Can send and respond to signals and record
experiences

NEUROTRANSMITTERS Dopamine
Natural Amphetamine Motor coordination, cognition, mood, attention and
learning, metabolism (BP, MR, digestion) – positive reinforcement
Serotonin (PNS and CNS) Provides a healing, nourishing, satisfied feeling in the
body – allows you to sleep naturally, enjoy time and think rationally
GABA Chief inhibitory neurotransmitter Relaxation, anti-anxiety, involved in endorphin production
Acetylcholine Cognition, memory, arousal Deficiency = lower creativity, learning

CENTRAL NERVOUS SYSTEMTHE BRAIN
Control Centre 3 parts:
Forebrain: receiving and processing sensory information, thinking, perceiving, producing and understanding language, and controlling motor function
Conscious perception Cerebrum, cerebral cortex Limbic system (hypothalamus)
Midbrain: auditory/visual function and motor systems,
Hindbrain: Maintaining balance and equilibrium, movement coordination, and the conduction of sensory information.
Pons, cerebellum, medulla oblongata (ANS)

RELATED TO SOCIAL HEALTH
People who share common environments, social groups are also likely to share perspectives.
People who suppress similar emotions have exhibited similar manifestations of disease
Connectedness between individuals Compassion effect

NERVOUS SYSTEM, ENDOCRINE SYSTEM, ENERGY
The Crown Chakra (7th)Associated with the pineal gland and wake/sleep or seasonal patterns. (Serotonin and Dopamine)
The Third Eye Chakra (6th)Associated with the limbic system, memories, emotional life and behaviour

THE DEEP MIND
The sub-conscious, habits, reactions, perceptions
What is its role in general? To what extent does it play a role in our
health? Contribute to healing? Something that we can “tap in to”?
![Page 18: SOCIAL DETERMINANTS AND BIOLOGY How determinants get Under the Skin (and into the brain) Colbran Marjerrison.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649cef5503460f949bda34/html5/thumbnails/18.jpg)
NEUROLOGY/ENDOCRINOLOGY
Neuronal network Brain, spine, body
Endocrine system How body response to environmental signals
Self conscious/Sub conscious mind Advanced practitioners are able to control
“involuntary” activity Perspiration
The God Spot
![Page 19: SOCIAL DETERMINANTS AND BIOLOGY How determinants get Under the Skin (and into the brain) Colbran Marjerrison.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649cef5503460f949bda34/html5/thumbnails/19.jpg)
IMMUNOLOGY
Immune System Interesting to consider from perspective of
promoting health, and not preventing disease Responds directly and/or immediately to
environmental signals Involved in differentiation of self from non-self,
regulation of somatic systems (reproductive function, digestion, filtering) injury/healing
Inflammatory response is hand in hand with stress

A NEW PERSPECTIVE
“ They [science and spirituality] are complementary views on reality each exploring a different realm. Only when we mistakenly assume them to be referring to the same realm does conflict arise”
![Page 21: SOCIAL DETERMINANTS AND BIOLOGY How determinants get Under the Skin (and into the brain) Colbran Marjerrison.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649cef5503460f949bda34/html5/thumbnails/21.jpg)
QUESTIONS TO BE ANSWERED
Deep mind : biological or spiritual? What fuels the machine of the body? What defines who you are? How are some people more connected
to the divine than others? Practice, choice? …. Biology?
Role in health, healing, medicine?
