Quizplus · Accepted Answer

The pons, specifically the locus coeruleus, plays a key role in regulating the sleep-wake cycle. Dysfunction in this area can lead to difficulties staying awake during the day and sleeping through the night. The cerebellum, basal ganglia, and substantia nigra are not directly involved in sleep regulation.
