inferior parietal lobule

The lower half of the posterior segment of the parietal lobe of the brain. The anterior segment of the parietal lobe comprises the postcentral gyrus. Behind this gyrus, the remainder of the parietal lobe is divided by a longitudinal sulcus, the intraparietal sulcus. The region of the parietal lobe above this sulcus is called the superior parietal lobule; the region below the sulcus is called the inferior parietal lobule. The inferior parietal lobule merges into the occipital and temporal lobes. Synonym: inferior parietal gyrusSee also: lobule
