---

This page covers biological details of component Medial 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) -> Medial Septal Group (FAM.FT.SEP.MG) -> Medial Septal Nucleus (FAM.FT.SEP.MED) (see Mind Maps)
• Type: nucleus
• Brain area: Forebrain - Affective Motivations Area
• Role: processor.affective.memory
• Function: affect HC for spatial learning, generation of theta waves
• Notes to function: output nucleus; projections from AM and HC overlap; control theta rythm and exprolatory behavior; from/to MFB to fornix fimbria
