The gyri of the lateral surface of the occipital lobe are usually referred to as lateral occipital gyri.
On the medial surface, the wedge-shaped area between the parietooccipital and calcarine sulci is called the cuneus (L. wedge).
The gyrus inferior to the calcarine sulcus is the lingual gyrus.
The lingual gyrus is adjacent to the posterior portion of the occipitotemporal gyrus and is separated from it by the collateral sulcus.
It is continuous anteriorly with the parahippocampal gyrus.
The transition from lingual to parahippocampal gyrus occurs at the isthmus of the cingulate gyrus.
