This page covers biological details of component Caudal Precuneus. Region is part of aHuman target integrated biological model.

• Top-down path to region: Cerebral Cortex -> Parietal Lobe (NC.LOBE.PAR) -> Superior Parietal Lobule (NC.SPL) -> Caudal Precuneus (NPE.NC.SPL.PG) (see Mind Maps)
• Type: cortex
• Brain area: Neocortical Brain - Polymodal Execution Area
• Brodmann ID: 07
• Role: processor
• Function: Controlling spatially guided behavior with respect to visual and tactile information
• Notes to function: caudal, 7A=PG+Opt
