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

Components
(generated)
Component items:
- Posterior Eye Field (NPE.NC.IPS.PEF): Reflexive saccade triggering
- Medial Intraparietal Sulcus (NPE.NC.IPS.MIP): Encode location of reach target in nose-centered coordinates
- Lateral Intraparietal Sulcus (NPE.NC.IPS.LIP): Representing saliency of spatial locations, and attention to locations
- Ventral Intraparietal Sulcus (NSA.NC.IPS.VIP): Merge visual, somatosensory, auditory, and vestibular senses
- Anterior Intraparietal Sulcus (NSA.NC.IPS.AIP): Represent shape, size, and orientation of objects to be grasped
