occipital gyrus (OG)

The term occipital gyrus refers to the major convolution on the lateral surface of the occipital lobe of the macaque cerebral cortex. Defined by dissection, it is bounded rostrally by the lunate sulcus of the human, which separates it from the angular gyrus of the parietal lobe, and ventrally by the inferior occipital sulcus, which separates it from the inferior occipital gyrus. On the mesial surface of the hemisphere it is quite small, partially separated from the cuneus dorsally by the superior calcarine fissure and from the inferior occipital gyrus ventrally by the inferior calcarine fissure ( Martin-2000 ). Topologically it is equivalent to a combination of the superior occipital gyrus and the middle occipital gyrus of the human. It is not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).

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.
