Quizplus · Accepted Answer

The reticular formation is a network of neurons located at the base of the brainstem (where the brain meets the spinal cord) that projects signals up to higher brain regions and down to the spinal cord. It plays a critical role in regulating attention and sleep, among other functions. The cerebellum is involved in motor control and coordination, the hypothalamus is involved in regulating basic bodily functions such as hunger and thirst, and the substantia nigra is involved in movement control and dopamine production.
