The term posterior transverse limb of the lateral fissure (ltfptr) 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 anterior transverse limb of the lateral fissure and the branching of the terminal ascending limb of the lateral fissure (ltftal) and the terminal descending limb of the lateral fissure (ltftdl)) ( 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 1 Sep 2024.
