Suprachiasmatic Nucleus
@@Home -> BiologicalLifeResearch -> BrainAreaLAC -> BrainRegionLAC_FD_HT_SCN
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: relay
- Function: Regulate the circadian cycle, 24-hour rhythms
