Quizplus · Accepted Answer

The suprachiasmatic nucleus (SCN) serves as the body's "master clock," regulating the sleep-wake cycle, hormone secretion, and other physiological processes based on environmental cues such as light and darkness. The lentiform nucleus, caudate nucleus, and basal nucleus are all involved in motor control and cognitive functions, but not in regulating circadian rhythms.
