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 [OverallMindMaps 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

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