Structure

Parietal cortex occupies 20–25% of the surface area in human cerebral cortex (Mountcastle 2005). Posterior parietal cortex (posterior to the posterior central gyrus) is divided anatomically into superior and inferior lobules/areas (SPA and IPA, respectively) by the intraparietal sulcus. Several subdivisions can be distinguished within each area by their anatomical and functional properties (Husain and Nachev 2007; Zigmond et al. 1999). In general, the SPA serves functions related to somesthesis, tactile cognition, visually guided action, and intentions to move, whereas, the IPA serves functions related to both spatial and nonspatial cognition, attention, and awareness of the body and space (Husain and Nachev 2007; Zigmond et al. 1999). This entry focuses on structure, function, and illness of the IPA with contrasts made to the SPA.

The IPA corresponds approximately to Brodmann areas...
