_____________ is the study of how genes support the function of neurons.

Oligodendrocytes form and maintain the blood-brain barrier.

Which of the following is NOT a function or characteristic of neurons?

What effect might a disease that destroyed oligodendrocytes have on neuronal function?

A drug that reduces the activity of the amygdala would likely:

The axon hillock is located:

Transcription factors increase or decrease gene transcription.

Compare and constrast the two types of microglial cells described in the textbook.

A disorder that damaged oligodendrocytes would be expected to impede neurotransmission.

Astrocytes respond to injury in the brain through a process called ________________.

A drug that increases appetite would likely affect:

Cerebrospinal is located in the following structures except:

The parasympathetic nervous system prepares the body for rigorous activity.

If an experimental drug produced physiological effects similar to nitric oxide,then a researcher would:

Diminished cerebral blood flow increases oxygen to neurons.

If physicians found that inflammation had caused damage to the blood-brain barrier,which cells would most likely be responsible?

Many drugs would be expected to produce rewarding effects by acting in the ________________.
