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: -In the brain, a small group of hypothalamic nerve cells, the suprachiasmatic nucleus (SCN), functions as a master circadian pacemaker controlling the timing of the sleep-wake cycle and coordinating this with circadian rhythms in other brain areas and other tissues to enhance behavioral adaptation.

Detailed explanation-3: -Neuroanatomy of the Suprachiasmatic Nucleus (SCN) The core mainly receives input from the retina and other brain regions.

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.
