1
Q

Anesthetic Drugs

A

Manufactured to do the following:

They block the release of neurotransmitters into the synaptic cleft

They form a stable complex with the receptors in the post-synaptic membrane, preventing them from combining with the neurotransmitters

Prevents the message to be sent through the chain of cells

2
Q

Cytoarchitectonic Maps

A

Structural maps that define functions

2 regions:
Motor vs. Sensory

3
Q

Association Areas

A

Areas of the brain that are not defined as motor or sensory

Examples: 18 and 19

4
Q

Neocortex (Overview)

A

The portion of the cortex that we see from the outside.

Throught to be the newest portion of the brain in our evolutionary process

Largest portion of the cortex - about 90%

Found only in mammals
