Medial occipitotemporal gyrus

Medial occipitotemporal gyrus is a cerebral gyrus which is situated on the inferior surface of the cerebral hemisphere, between the occipital pole and the temporal pole. Towards the back, there is a groove called the collateral sulcus, which separates the medial occipitotemporal gyrus from the parahippocampal gyrus. As we move towards the front, the collateral sulcus continues as the rhinal sulcus, further dividing the medial occipitotemporal gyrus from the front part of the parahippocampal gyrus and uncus.

It's important to note that different terminology is used in the literature. For example, the occipitotemporal gyrus is also known as the fusiform gyrus, and the occipitotemporal sulcus is sometimes referred to as the mid-fusiform sulcus. This sulcus divides the fusiform gyrus into two parts: the medial and lateral fusiform subparts. Therefore, the medial and lateral occipitotemporal gyri can also be called the medial and lateral fusiform gyrus subparts. In other words, we can also say that the collateral and rhinal sulci separate the parahippocampal gyrus from the medial fusiform gyrus.
