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 (for directing eye movements and reaching) and visual attention.
The IPS is also thought to play a role in other functions, including processing symbolic numerical information[4], and interpreting the intent of others.[5]
