Midsagittal view of cerebrum. Brainstem and cerebellum have been removed. The cingulate gyrus is closely associated with the corpus callosum throughout its length and is separated from the frontal and parietal lobes by the cingulate sulcus. The paracentral lobule is the medial continuation of the precentral and postcentral gyri and includes portions of the frontal and parietal lobes. Posteriorly, the parietooccipital sulcus separates the superior parietal lobe from the cuneus and lingual gyrus of the occipital lobe. The uncus is located on the medial aspect of the temporal lobe anterior to the parahippocampal gyrus. (Image courtesy of AL Rhoton, Jr.)
