Inferior occipital gyrus and sulcus*

The occipital gyri (OcG) are three gyri in parallel, along the lateral portion of the occipital lobe, also referred to as a composite structure in the brain.

The gyri are the superior occipital gyrus, the middle occipital gyrus, and the inferior occipital gyrus, and these are also known as the occipital face area.

The superior and inferior occipital sulci separates the three occipital gyri.

The intraoccipital sulcus, also known as the superior occipital sulcus, stems from the intraparietal sulcus and continues until the sulcus reaches the transverse occipital sulcus, separating the superior occipital gyrus from the middle occipital gyrus.

The transverse occipital sulcus comes down along the lateral occipital surface or the inferior occipital sulcus.
