Occipitotemporal sulcus
Medial surface of left cerebral hemisphere. The picture shows a dashed outline in red, known as the occipitotemporal sulcus.
The inferior surface of the temporal lobe is concave, and is continuous posteriorly with the tentorial surface of the occipital lobe. It is traversed by the occipitotemporal sulcus, also known as the lateral occipitotemporal sulcus which extends from near the occipital pole behind, to within a short distance of the temporal pole in front, but is frequently subdivided by bridging gyri.
