13. sensory switchboard
15. makes new memories
18. controls heartbeat and breathing
19. helps coordinate movement and control sleep
20. cortex that generates neural impulses that control the execution of movement.

2. linked to emotion
3. neuron extension that receives messages and directs them toward the cell body
4. axon fibers connecting the two cerebral hemispheres
6. ultimate control and information-processing center
8. fatty substance that insulates axon
