inferior occipital sulcus (iocs)

The term inferior occipital sulcus refers to a horizontal groove low on the lateral aspect of the occipital lobe of human cerebral cortex. It separates the middle occipital gyrus above from the inferior occipital gyrus below ( Duvernoy-1992 ). In the macaque it extends from the ventrolateral surface of the occipital lobe to the ventral surface and separates the occipital gyrus from the inferior occipital gyrus. Equivalent structures are not found in the smooth cerebral cortex of the rat and mouse ( NeuroNames ).

Also known as: inferior occipital sulcus, Sulcus occipitalis inferior, occipitoinferior sulcus

Models Where It Appears
Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
