The inferior parietal lobule (IPL) is the lower part of the parital lobe and is concernced with multiple aspects of sensory processing and sensorimotor integration. This area is located below the horizontal portion of the intraparietal sulcus and behind the lower part of the postcentral sulcus. It contains the angular sulcus which is a lobule bypassing the ascending posterior segment and the supramarginal gyri which is an arched lobule surrounding the end of the lateral fissure.
The IPL is considered to be a multimodel sensory association area and is known to be involved in oculomotor and attentional mechanisms, the establishment of maps of extrapersonal space, and the adaptive recalibration of eye-hand coordination. It is also involved in naming. The left IPL becomes activated when reading during semantic processing and when generating words or making syllable judgements. The IPL seems to become activated during short-term memory and word retrieval and becomes highly active when retrieving the meaning of words during semantic processing and semnatic decision tasks.
Damage to this area can lead to anomia, which is a condition of having difficulty with naming and describing objects or pictures. Pure blindness can also can also occur if damager occurs between the fiber pathways linking the left inferior parietal lobule with the visual cortex.
Of all the corical regions, the IPL is one of the last to mature functionally and anatomically.
