This page covers biological details of component Suprachiasmatic Nucleus. Region is part of aHuman target integrated biological model.

  • Top-down path to region: Forebrain Diencephalon -> Hypothalamus (FD.HT) -> Anterior Hypothalamus Area (LAC.FD.HT.AHT) -> Chiasmatic Area (LAC.FD.HT.CHS) -> Suprachiasmatic Nucleus (LAC.FD.HT.SCN) (see Mind Maps)
  • Type: nucleus
  • Brain area: Lower Brain - Autonomous Control Area
  • Role: processor.autonomic
  • Function: Regulate the circadian cycle, 24-hour rhythms
