what is the suprachiasmatic nucleus and what is its function?
Anatomy and Sleep Functions of the Brain's Suprachiasmatic Nucleus The suprachiasmatic nucleus is located in a foreward region of the brain called the hypothalamus. It contains a group of nerve cells (or neurons) that control your body's circadian rhythm. What is the Suprachiasmatic Nucleus That internal clock of the body does indeed exist and is called the suprachiasmatic nucleus. Our body is a very advanced system which has provision for all our needs. Through evolution, our bodies have developed a timetable for all our internal functions, based on the 24-hour cycle of day and night. The implementation and synchronization of the timetable, according to external stimuli, is controlled by the nucleus, which is a part of our brain.
