@@Home -> BiologicalLifeResearch -> BrainAreaFMM -> BrainRegionFMM_NC_PH_POS
This page covers biological details of component Postsubiculum. Region is part of aHuman target integrated biological model.
- Top-down path to region: Cerebral Cortex -> Parahippocampal Lobe (NC.LOBE.PH) -> Anterior Parahippocampal Gyrus (FMM.NC.PHA) -> Retrosubicular Area (FMM.NC.PHA.RS) -> Postsubiculum (FMM.NC.PH.POS) (see Mind Maps)
- Type: cortex
- Quality: L0
- Brain area: Forebrain - Memory Management Area (FMM)
- Area circuit: Orienting Control (MMAORIENT)
- Brodmann ID: 48
- Role: cortex.orienting
- Function: Visual association
- Comments: Retrosubicular Area, similar to BA-36, from perirhinal to presubiculum
- Notes to function:
- Detached dorsal part of presubiculum
- Integrate visual landmarks with internal representations of environments
