Occipitotemporal gyri

Occipitotemporal gyri are significant folds in the brain located on the bottom surface of the cerebral hemispheres. They stretch from the back of the brain at the occipital pole to the front at the temporal pole. These gyri include the medial and lateral occipitotemporal gyri. They are separated from each other by a groove known as the occipitotemporal sulcus. Alternatively, these gyri are collectively referred to as the fusiform gyrus. Within this gyrus there is dividing groove called a mid-fusiform sulcus, which separates it into the medial and lateral fusiform gyri. These terms are alternative names for the medial and lateral occipitotemporal gyri.

The ventral part of the fusiform gyrus, or occipitotemporal gyri, is involved in high-level visual processes such as recognizing face, identifying objects, and reading.
