@@Home -> BiologicalLifeResearch -> BrainAreaFAM -> BrainRegionFAM_FT_SEP_DBB
This page covers biological details of component Diagonal Band of Broca. 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) -> Diagonal Band of Broca (FAM.FT.SEP.DBB) (see Mind Maps)
- Type: nucleus
- Quality: L0
- Brain area: Forebrain - Affective Motivations Area (FAM)
- Area circuit: Memory Formation Affective Focus (FAMXMF)
- Role: processor.affective.memory
- Function: involved in generation of theta waves in hippocampus
- Notes to function:
- ACh and GABA
- ventral group - from stria terminalis to/from MFB
