This page covers biological details of component group Septal Nuclei. Component group is part of aHuman target integrated biological model.
- Top-down path to center: Forebrain Telencephalon -> Extended Amygdala (FAM.FT.EXTAM) -> Septal Nuclei (FAM.FT.SEP) (see Mind Maps)
- Function: Inhibition of fear and expression of pleasurable responses

Components
(generated)
Component items:
- Dorsal Septal Nucleus (FAM.FT.SEP.DS)
- Lateral Septal Group (FAM.FT.SEP.LG)
- Lateral Septal Nucleus: promote active stress coping behavior
- Septohippocampal Nucleus: participate in solving conflict between two or more competing goals, defensive circuit
- Medial Septal Group (FAM.FT.SEP.MG)
- Medial Septal Nucleus: affect HC for spatial learning, generation of theta waves
- Diagonal Band of Broca: involved in generation of theta waves in hippocampus
- Lateral Septal Group (FAM.FT.SEP.LG)
- Posterior Septal Group (FAM.FT.SEP.PG)
- Bed Nucleus of Anterior Commissure: projection to contralateral HC
- Septofimbrial Nucleus: afferent to medial habenula, primary input to indirect encoding negative feedback
- Triangular Septal Nucleus: afferent to medial habenula, interpeduncular nucleus
