Figure 1.

Schematic representation of the anatomical and functional organization of the posterior parietal cortex. An axial (horizontal) slice through the brain of a healthy individual has been chosen to depict the major sulcus within the posterior parietal cortex, the intraparietal sulcus (IPS—outlined by the use of a black line). Functional areas selective for grasping (depicted in green), reaching (depicted in red) and eye movements (depicted in light blue) have been superimposed. aIPS, anterior IPS; mIPS, medial IPS.
