1. SOCIAL DETERMINANTS AND BIOLOGY How determinants get Under the Skin (and into the brain) Colbran Marjerrison

2.  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

8. SNS: Fight or Flight PNS : Rest and Digest, or Feed and Breed

9.  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

10.  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

13.  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: M aintaining balance and equilibrium, movement coordination, and the conduction of sensory information.  Pons, cerebellum, medulla oblongata (ANS)

15.  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

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

17. 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”?

18.  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

19. 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

20. “ 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”

21.  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?
