CHAPTER 1: Structural and Functional Organization of the Nervous System

Functional neuroanatomy is defined as:

A. knowledge of the morphology and circuitry of the nervous system.

B. effects activation or inactivation of particular structures have on behavior.

C. interaction of physiology and anatomy of particular central nervous system structures.

D. chemical transmission of information via neurotransmitters.

B. effects activation or inactivation of particular structures have on behavior.

The ability to change neural pathways in response to lifetime demands is called:

A. phagocytosis.

B. neuroplasticity.

C. neurotransmission.

D. synaptic transmission.

B. neuroplasticity.
