medial parieto-occipital sulcus

medial parieto-occipital sulcus (apos)

The term medial parieto-occipital sulcus refers to a small three-limbed groove located on the medial surface of the cerebral hemisphere of the macaque ( Martin-2000 ). Defined by dissection, it marks the four-way junction of the occipital lobe and parietal lobe with the posterior cingulate gyrus and isthmus of the cingulate gyrus ( limbic lobe ). It is equivalent to the lower part of the splenial sulcus of the human ( Ono-1990 ). In the macaque the upper part, the subparietal sulcus, is detached ( Bonin-1947 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).

Also known as: Sulcus parieto-occipitalis anterior, medial parieto-occipital fissure, anterior parieto-occipital sulcus, medial parieto-occipital sulcus, accessory parieto-occipital 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.
