---

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
• Brain area: Forebrain - Memory Management Area
• Brodmann ID: 48
• Role: cortex.orienting
• Function: Visual association
• Notes to function: Detached dorsal part of presubiculum; Integrate visual landmarks with internal representations of environments
