Nucleus Accumbens Shell
@@Home -> BiologicalLifeResearch -> BrainAreaFEC -> BrainRegionFEC_FT_ACC_SH
This page covers biological details of component Nucleus Accumbens Shell. Region is part of aHuman target integrated biological model.
- Top-down path to region: Forebrain Telencephalon -> Basal Ganglia (FEC.FT.BG) -> Striatum (FEC.FT.ST) -> Ventral Striatum (FEC.FT.VST) -> Accumbens Nucleus (FEC.FT.ACC) -> Nucleus Accumbens Shell (FEC.FT.ACC.SH) (see Mind Maps)
- Type: nucleus
- Brain area: Forebrain - Execution Control Area
- Role: basal.ganglia.striatum
- Function: cognitive processing of motivational salience (wanting) as well as reward and reinforcement effects
