The [[cingulate gyrus]] is divided into anterior ([[frontal lobe]]) and posterior ([[parietal lobe]]) portions in the area of the [[central sulcus]]. The rostral part surrounds the [[genu]] of the [[corpus callosum]] and ends in the [[subcallosal cortex]]; it continues posteriorly around the [[splenium]] of the corpus callosum to become the [[parahippocampal gyrus]] at the level of the [[cingulate isthmus]]. The adjacent areas of the [[hemisphere]] comprise the mesial and hemispheric surface of [[F1]] with the [[SMA]], the [[paracentral lobule]], and the [[precuneus]] in the parietal lobe von Lehe and Schramm summarized the areas adjacent to the cingulate gyrus at the interhemispheric surface as “[[supracingular]]”).
