Posterior parietal cortex:
the region of the parietal cortex that is posterior to the primary somatosensory cortex and its adjacent sulcus, the postcentral sulcus. The posterior parietal cortex is thought to be involved in a variety of functions, including attention, language, and number processing. Damage to the posterior parietal cortex can result in a condition known as hemispatial neglect.
