Exam 5: The Central Nervous System

The ____________________ association cortex is the part of the brain that "brainstorms" or thinks.

What are the three higher motor areas of the cortex that are involved in voluntary decision-making?

What is the outer shell of each hemisphere composed of?

The basal nuclei play an important inhibitory role in sensory control.

A delta rhythm in the brain is associated with deep ____________________ slow-wave sleep.

What compound binds to the AMPA receptors and NMDA receptors of the postsynaptic neuron?

What is the estimated number of neurons in the brain?

The ____________________ serves as a "relay station" for preliminary processing of sensory input.

What area of the brain is associated with language comprehension?

Sensitization is defined as increased responsiveness to mild stimuli following a strong or noxious stimulus.

Cerebrospinal fluid (CSF)is formed primarily by the ____.

The spinal cord ends (terminates)in rootlets called the ____________________.

The motor cortex is activated by a widespread pattern of neuronal discharge,called the ____________________.

Throughout the entire CNS,white matter consists mostly of densely packaged neuronal cell bodies and their dendrites,in addition to most glial cells.

What are the two forms of amnesia?

Only the brain interstitial fluid (not the blood or CSF)comes into direct contact with the neurons and glial cells.

The vegetative state is characterized by long sleep-wake cycles and detectable awareness.

Where is Broca's area located?

The neural change responsible for retention or storage of knowledge is known as a(n)____.
