Lateral Septal Nucleus
@@Home -> BiologicalLifeResearch -> BrainAreaFAM -> BrainRegionFAM_FT_SEP_LT
This page covers biological details of component Lateral Septal Nucleus. Region is part of aHuman target integrated biological model.
- Top-down path to region: Forebrain Telencephalon -> Extended Amygdala (FAM.FT.EXTAM) -> Septal Nuclei (FAM.FT.SEP) -> Dorsal Septal Nucleus (FAM.FT.SEP.DS) -> Lateral Septal Group (FAM.FT.SEP.LG) -> Lateral Septal Nucleus (FAM.FT.SEP.LT) (see Mind Maps)
- Type: nucleus
- Brain area: Forebrain - Affective Motivations Area
- Role: processor.affective
- Function: promote active stress coping behavior
