@@Home -> BiologicalLifeResearch -> BrainAreaFEC -> BrainRegionFEC_FT_SNC_MED
This page covers biological details of component Substantia Nigra Pars Compacta Medial. Region is part of aHuman target integrated biological model.
- Top-down path to region: Forebrain Telencephalon -> Basal Ganglia (FEC.FT.BG) -> Substantia Nigra (FEC.FT.SN) -> Substantia Nigra Pars Compacta (FEC.FT.SNC) -> Substantia Nigra Pars Compacta Medial (FEC.FT.SNC.MED) (see Mind Maps)
- Type: nucleus
- Brain area: Forebrain - Execution Control Area
- Role: basal.ganglia.nigracompacta
- Function: motivational loop
- Notes to function: VP, ventral circuits
