The Brain Lesson
Understanding the four brain systems
(12 slides)
creatively compiled by dr. michael farnworth
The brain is a tapestry of wet electro-magnetic frequency fields,
that is bathed in complex levels of potential neural-chemicalhormonal interactions that provide the holistic interwoven brain
and body communication.
This lesson represents some very important ideas in
understanding the basic functions, imprinting and development
of the brain in childhood.
It is important in relationship to raising children and in
understanding the impact of fear, threat and stress in their, and
our own lives.
Take time to learn the dynamics of brain function and see what
insight and understanding will surface in relation to your own
life.
An introduction to the four brain systems…
• The first brain system is the brain stem which is responsible
for our survival. (reptilian brain)
• The second brain system is the limbic brain and is our
emotional-cognitive brain. (mammalian brain)
• The third brain system is our neo-cortex brain and is our
language-intelligence brain. (human brain)
• The fourth brain system is our pre frontal lobes and is
responsible for our higher thinking and affect regulation.
(angel brain)
In reality, the four brain systems are not really separate but
are woven together in a sophisticated tapestry.
We will talk about them as if they were separate to help
simplify the dynamics of brain function.
The first two brains: the stem and limbic will also be
referred to as the Old Brain because they developed firstnot only in our prenatal life but also in our species
evolutionary history.
The New Brain is made up of the neo-cortex and the prefrontal lobes.

Interesting Brain Facts
• Early Brain Growth
During the first month of life, the number of connections or
synapses, dramatically increases from 50 trillion to 1
quadrillion. If an infant's body grew at a comparable rate, his
weight would increase from 8.5 pounds at birth to 170
pounds at one month old.
• Abused Children Have Smaller Brains
Parts of the brain of a severely abused and neglected child
can be substantially smaller than that of a healthy child.
Interesting brain facts continued
• Reading Aloud Stimulates Child Development
Reading aloud to children helps stimulate brain
development, yet only 50% of infants and toddlers are
routinely read to by their parents.
• Rhythm In Development
Research shows brain growth contains its own rhythm.
Certain skills come into preeminence for a period of
intensive networking. At three months, the visual cortex
dominates synapse formation.
More interesting brain facts
• Miles and Miles of Neurons
There are one hundred billion neurons in the brain. A stack of
one hundred billion pieces of paper would be about 5000
miles high, the distance from San Francisco to London.
• No Pain in Brain
There is no sense of pain within the brain itself. This fact
allows neurosurgeons to probe areas of the brain while the
patient is awake. Feedback from the patient during these
probes is useful for identifying important regions, such as
those for speech, that are spared if possible.
