1. The Human Brain

2. The Human Brain
The human brain is a gelatinous three-pound lump of fat, connective tissue, spinal fluid and nerve cells.
Its neurons generate some 25 watt of total power.
It is in contact with every living cell in the body
It feels no pain!

3. The Human Brain
The human brain is a greedy, thirsty, selfish vampire that guzzles a pint-and-a-half of blood a minute.
No matter what is happening to the body, the brain takes its nourishment first.
For unknown reasons, the brain needs more blood when the body is asleep than when awake.

4. Three Functional Divisions:
Cerebrum Cerebellum Brainstem
Sensory muscle coordination vital regulations
and motor and balance heart, lungs, etc.

5. Gyri, sulci and lobes of the cerebrum

6. Hemispheres The Brain has two sides:
Left hemisphere
Right hemisphere
Connected by the Corpus Callosum
Left brain controls the right side of the body
Right brain controls the left side of the body

7. Left side: Deals in Time
Thinking process in sequence
Logic
Words
Past, Present, Future

8. Right side: Deals with space
Thinking process in space
Wholeness (ability to sense the whole thing)
Patterns
Visual concepts

9. How we learn about the brain
Mammalian brains
Humans with disorders
Phantom Limb:
Prosopagnosia:
Split Brain:

10. Everyone is born with 2 hemispheres
90% of the population is left brain
9.9% of the population is both sides to some degree
Very few are completely right brain
If mother relates space ( large room, out doors) at feeding time, right brain develops

11. Here’s an example of both sides working together:
If you don’t perceive any illusions within the patten, you are complete right sided
If you see an illusion within the patterns that move constantly as you move your eyes through the images, you are left sided
If you see a staggering illusion, you are both right and left sided!
