Intraparietal Sulcus - Other Roles of The IPS

Other Roles of The IPS

Five regions of the intraparietal sulcus (IPS): anterior, lateral, ventral, caudal, and medial

• LIP & VIP: involved in visual attention and saccadic eye movements
• VIP & MIP: visual control of reaching and pointing
• AIP: visual control of grasping and manipulating hand movements
• CIP: perception of depth from stereopsis

All of these areas have projections to the frontal lobe for executive control.

Activity in the intraparietal sulcus has also been associated with the learning of sequences of finger movements. (http://jn.physiology.org/content/88/4/2035.full)
