Intraparietal sulcus

Last revised by Maxime St-Amant on 18 Apr 2018

The intraparietal sulcus together with the postcentral sulcus, is one of the two main sulci of the parietal lobe. It runs from the post-central sulcus towards the occipital pole, dividing the lateral parietal lobe into the superior and inferior parietal lobules. The floor of the intraparietal sulcus is related to the occipital horn.

Functionally, the cortical regions of the intraparietal sulcus play important roles in the visuomotor coordination of eye and hand movement and in short-term visual memory.
