The intraparietal sulcus (IPS) is located on the lateral surface of the parietal lobe, and consists of an oblique and a horizontal portion. The IPS contains a series of functionally distinct subregions that have been intensively investigated using both single cell neurophysiology in primates[1][2] and human functional neuroimaging.[3] Its principal functions are related to perceptual-motor coordination (e.g., directing eye movements and reaching) and visual attention, which allows for visually-guided pointing, grasping, and object manipulation that can produce a desired effect.

The IPS is also thought to play a role in other functions, including processing symbolic numerical information,[4] visuospatial working memory,[5] decision-making,[6] and interpreting the intent of others.[7][unreliable medical source?]
