The term paracentral sulcus refers to a superficial feature of the frontal lobe of the human. Located on the medial surface, it separates the paracentral lobule caudally from the superior frontal gyrus rostrally. In some cases it is continuous with the superior precentral sulcus on the dorsal surface of the lobe ( Carpenter-1983 ). Identified by dissection, it is not found in the macaque nor in the smooth cerebral cortex of the rat and mouse ( NeuroNames ).
