  • outer layer of the cerebrum
  • 2 cortices and 2 hemispheres

4

Define cerebellum.

5

The ____ lobe controls more abstract aspects of our thinking and personality.

frontal

6

This is the place where 2 things are joined.

commissure

7

  • Situated between the cerebral cortex and the midbrain
  • surrounds the 3rd ventricle
  • relays sensory and motor signals to the cerebral cortex
  • regulates consciousness, sleep, and alertness

thalamus

8

Define thalamus.

  • situated between the cerebral cortex and the midbrain
  • surrounds the 3rd ventricle
  • relays sensory and motor signals to the cerebral cortex
  • regulates consciousness, sleep, and alertness

9

cortex

10

Belonging to or occurring on the same side of the body

ipsilateral

11

Define White Matter.

myelinated nerve fibers

12

Define homunculus.

a map of the representation of the body on the motor cortex that looks like a distorted human

13

Define synapse.

a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron

14

These axons carry information toward the cell body.

afferent

15

What makes up the thalamus?

clusters of cell bodies called nuceli

16

This is the point-for-point correspondence of an area of the body to a specific point on the central nervous system.

somatotopy

17

This is the ability of synapses to strengthen or weaken over time, in response to increases or decreases in their activity.

synaptic plasticity

18

Define ipsilateral.

belonging to or occurring on the same side of the body
