The term anterior transverse limb of the lateral fissure (ltfatr) refers to a superficial feature of the parietal lobe (PLB) in the human ( Ture-1999 ). Identified by dissection, it is a branch from the lateral fissure (ltf) into the supramarginal gyrus (SMG) between the postcentral sulcus (pocs) and the posterior transverse limb of the lateral fissure (ltfptr) ( Ture-1999 ).. Branches from the ltf are not found in the macaque, nor is the ltf itself found in the smooth cerebral cortex (CTX) of the rat or mouse ( NeuroNames ). Updated 2 Sep 2024.
