The term lunate sulcus of the human (lush) refers to a minor vertical cleft near the occipital pole (ocp) of the occipital lobe (OLB) in the human. It is Identified by dissection ( Duvernoy-1992 ), In many cases it is intersected by the the lateral occipital sulcus (locs), of which some authors consider it a part ( Van Essen Lab-2002 ). It is not topologically equivalent to the lunate sulcus of the macaque (lusm) ( Martin-2000 ). Equivalent structures are not found in the macaque or the smooth cerebral cortex of the rat and mouse ( NeuroNames ). Updated 25 Aug 2024.
