The precuneus is a part of the superior parietal lobule forward of the occipital lobe (cuneus). It is hidden in the medial longitudinal fissure between the two cerebral hemispheres. It is sometimes described as the medial area of the superior parietal cortex. The precuneus is bounded anteriorly by the marginal branch of the cingulate sulcus posteriorly by the parietooccipital sulcus and inferiorly by the subparietal sulcus.
