CONCIOUSNESS

to think and be aware of our existence

CORPUS COLLOSUM

a large bundle of nerve fibers that connect corresponding parts of one side of the brain with those of the other.

SPLIT-BRAIN OPERATION

cutting the corpus collosum

THE CORPUS COLLOSUM ENABLES

the two hemispheres to share information

AFTER THE S.B OPERATION, THE TWO SIDES...

operate independently

VERBAL COMMUNICATION ORIGINATES IN

left hemisphere

REDUCTION

a phenomena is described in terms of  more elementary processes that underlie it.

FIRST MAN TO SAY BRAIN WAS THE SEAT OF ALL EMOTIONS AND THOUGHTS

Hippocrates

DESCARTES PROPOSITION ON REFLEXES

dualism. The mind and brain are two different things. The brain is simply where the mind operates.

PINEAL BODY

Descartes thought: where interation between mind and body take place. A small organ on top of the brain stem.

DESCARTES VIEW ON VENTRICLES

filled with fluid; when the mind decides to perform an action, tilts pineal body in particular direction like a joystick.

GALVANI FOUND

that some rxns are involuntary even when the nerves and muscles are detatched from the rest of the body.

MULLER AND HIS DOCTRINE OF SPECIFIC NERVE ENERGIES

b/c all nerve fibers carry the same type of message, sensory information must be specified by the particular nerve fibers that are active.

FLOURENS

experimental ablation- removing parts of the animals' brain and observing the animal's behavior.

BROCA

discovered that a portion of the left side of the brain is responsible for speech.

PRIMARY MOTOR CORTEX

the nerve cells there communicate directly with those that cause muscle contractions

PART OF PRIMARY MOTOR CORTEX THAT PRODUCES SPEECH COMMUNICATES AND CONTROLS

THE PART THAT CONTROLS THE MUSCLES, LIPS, AND TONGUE

HELMHOLTZ

 -measured the speed of conduction in nerves (90 ft per sec)

- studied vision and audition

FUNCTIONALISM

EVERY CHARACTERISTIC OF AN ORGANISM CARRIES OUT SPECIFIC FUNCTIONS. NOT TO BE CONFUSED WITH HAVING A PURPOSE.
