PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -The suprachiasmatic nucleus (SCN) is a bilateral structure located in the anterior part of the hypothalamus. It is the central pacemaker of the circadian timing system and regulates most circadian rhythms in the body.

Detailed explanation-2: -Light directly entrains the master clock, the suprachiasmatic nucleus (SCN) which lies in the hypothalamus of the brain and is responsible for synchronizing internal rhythms.

Detailed explanation-3: -The circadian biological clock is controlled by a part of the brain called the Suprachiasmatic Nucleus (SCN), a group of cells in the hypothalamus that respond to light and dark signals.

Detailed explanation-4: -The tiny suprachiasmatic nucleus (SCN) of the hypothalamus plays a central role in the daily programming of organismic functions by regulating day-to-day oscillations of the internal milieu and synchronizing them to the changing cycles of day and night and of body state.

Detailed explanation-5: -Circadian rhythms are regulated by small nuclei in the middle of the brain. They are called the suprachiasmatic nuclei (SCN).
