The suprachiasmatic nucleus (SCN) is a structure in the hypothalamus that serves as the body's circadian (daily) clock. It regulates a variety of physiological processes, including the production of melatonin by the pineal gland. Melatonin is a hormone that helps regulate sleep and wake cycles. The SCN receives information about light and dark cycles from the eyes and coordinates the timing of the release of melatonin accordingly.
