The “Science for Dummies” of a Pastoral EncounterKaren Elsworth
The Biology of Touch
Slide2The Five Special Senses
Five special senses, sight, smell, hearing, taste (all in the head) and touch
All tissues and organs of the body develop from three primitive layers of cells that make up the embryo: Endoderm (internal organs) Mesoderm (connective tissue, bones and muscle) and Ectoderm (Skin and the nervous system)
Touch is the “Mother of all Senses”
“To Touch the surface is to stir the depths” Deane
Juhan
Slide3Physiology of skin
The skin covers the entire body
Skin and Brain develop from the same embryological cells and form a continuous medium
Skin is the fastest messenger carrier to the Autonomic nervous system and the immune system
Waterproof
Temperature regulator
Organ of excretion
Largest sense organ of the body
Highly intelligent second only to brain itself
Slide4Of special note is CONNECTIVE TISSUE
Simple Cross section of Skin

Slide5Different Types of Skin Receptors
Once thought different receptors
Responsible for different sensations.
Recently disproved: some cells
respond to multiple different stimuli.
Ruffini
– Pressure and heat
Pacini
– vibration
Meissner – light touch
Krause – Cold
Free endings – Pain
Merkel – Initial touch and extended contact
Slide6Connective Tissue
Nose to Toes
Matrix enveloping every structure
Binds cells into tissues and tissues into organs
Cements muscle to bone
Wraps around every
n
erve and vessel
Continuous network throughout the body
Most abundant tissue in the body
Protects the body/strong web like
Compartmentalises structures
Blood (fluid connective tissue) major transport system in the body
Highly enervated

Slide10Skin as surface to the Brain
Embryology (foetal development) skin=brain
Through ectoderm
Skin/Brain 50 Trillion cells living in community
Each cell like an individual, all communicating
Touch
tells me about my
environment
Touch tells me about
myself
Touch tells others about me
Slide11Touch and Psychological Development
Happy and unhappy mice
Touch is food Ref. Montague, A:

Slide16Conscious Mind
40 bits per second
Lasts only 20’
Slow, Creative
Last to develop, late adolescence and beyond / self consciousness
Past/Future
15% of brain activity
Subconscious Mind
400 million bits per second
Fast Habitual
Age 0- 6yrs data downloading from environment
Present moment
85% brain activity
Comparison between Conscious and Subconscious Mind
Slide17Sympathetic
Principle
N
eurotransmitter noradrenalin
Primarily concerned with responses to the environment (including responses to stress), expends resources
Flight/fight
Increased heart rate
Danger response
P
arasympathetic
Principle Neurotransmitter acetyl choline
Primarily concerned with vegetative processes, build up and conserves resources
Digestion/Absorption
Excretion
Restful Function
Autonomic nervous System
Influenced by physical touch of skin subconscious
Regulated by the Hypothalamus

Slide19Supremacy of DNA?
Work of Bruce Lipton ‘Biology of Belief’
Cell membrane = ‘Brain’ of cell
Skin/Brain interface= Environmental receptor
“When a gene product is needed (protein) a signal from the environment NOT an emergent property of the gene itself
activates the expression of that gene.”
Niijout
(H.F) 1990 Metaphors in the Role of Genes in Development
Development of field of EPIGENETICS
Therefore: PRIMACY OF THE ENVIRONMENT
PERCEPTION = AWARENESS OF THE ENVIRONMENT THROUGH
PHYSICAL SENSATION
(Webster Dictionary)
NB Constant interaction between areas of the brain/subconscious
Mechanical and energetic

- Clinical Director
‘We are at the beginning of an age of Compassion, our knowledge of neuroscience is showing the positive effect of compassion and how profound it can be.’
Slide28Summary of a Pastoral EncounterWe each bring:
Product of Genetics and Epigenetics
Programming and processing
Hierarchy of development
PERCEPTION
Awareness of environment through senses
Dominance of Subconscious
Heart influence
We Produce a change in the FIELD
by PRESENCE without direct touch
Direct touch leads to mechanical changes to nervous system and brain + FIELD (from presence)
