Exam 2: Neuroscience and Behavior

The corpus callosum is an important midbrain structure that contains many dopamine-producing neurons.

The corpus callosum is a thick band of axons that:

Which of the following statements about glial cells is FALSE?

When a neuron depolarizes and begins an action potential, sodium ions move into the axon and then potassium ions move out of the axon.

During the process of reuptake, glial cells absorb unused neurotransmitters and then transfer the neurotransmitters to the appropriate neuron.

In the normal intact brain, the left and right cerebral hemispheres function in an integrated fashion.
