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 (HTA.FD.HT) -> Anterior Hypothalamus Area (HTA.FD.HT.AHT) -> Chiasmatic Area (HTA.FD.HT.CHS) -> Suprachiasmatic Nucleus (LAC.FD.HT.SCN) (see Mind Maps)
• Type: nucleus
• Brain area: Lower Brain - Autonomous Control Area
• Role: relay
• Function: Regulate the circadian cycle, 24-hour rhythms
