medial parieto-occipital sulcus
Acronym: 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 subparietal sulcus of the human ( Ono-1990 ). In the macaque the upper part is detached and only it is referred to as subparietal sulcus ( Bonin-1947 ).
     Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).

Also known as: accessory parieto-occipital sulcus, medial parieto-occipital fissureNeuroNames ID : 53
