This page covers biological details of component group Intraparietal Sulcus. Component group is part of aHuman target integrated biological model.

  • Top-down path to center: Cerebral Cortex -> Parietal Lobe (NC.LOBE.PAR) -> Intraparietal Sulcus (NSA.NC.IPS) (see Mind Maps)
  • Function: Perceptual-motor coordination and visual attention, eye movements and reaching
  • Notes to function: PG, Control of saccadic eye movements, visual control of grasping
