Presentation Transcript

  1. How determinants get Under the Skin (and into the brain) Social determinants and Biology ColbranMarjerrison

  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 How does it get under the skin?

  3. Nervous System Central Nervous System Peripheral Nervous System Brain Spinal Chord Sensory Autonomic Somatic Vision Hearing Touch Taste Smell Spinal Nerves Cranial Nerves Association Nerves Enteric Sympathetic Parasympathetic

  4. Somatic/sensory N.S. & the Reflex Arc

  5. How do the Nerves work?The action potential

  6. How do the Nerves work? SYNAPSES

  7. AutonomicNervousSystem • SNS: • Fight or Flight • PNS : • Rest and Digest, or Feed and Breed

  8. 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 Enteric Nervous System

  9. 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 Neurotransmitters

  10. Cocaine Use

  11. External StimulationOpioid system

  12. 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) Central Nervous SystemThe Brain

  13. 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 Related to social health

  14. 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

  15. 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”? The deep mind

  16. 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 Neurology/Endocrinology

  17. 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 immunology

  18. “ 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” A new perspective

  19. 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? Questions to be answered
