The term postcentral sulcus (pocs) refers to a superficial feature of the lateral aspect of the parietal lobe (PLB). Identified by dissection in the human, it is located caudal and parallel to the central sulcus (cns), it is continuous in about half of cases and discontinuous with two or three segments in half. Dorsally it separates the postcentral gyrus (POG) from the superior parietal lobule (SPL) and ventrally from the supramarginal gyrus (SMG) of the inferior parietal lobule (IPL) ( Ono-1990 ). In the macaque it is a short cleft located on the dorsolateral surface of the PLB. It partially separates the POG from the SPL ( Martin-2000 ). Equivalent features are not found in the smooth cerebral cortex (CTX) of the rat or mouse ( NeuroNames ). Updated 25 Aug 2024.
