diagonal limb of the lateral fissure
Acronym: ltrfdg
The term diagonal limb of the lateral fissure (ltfdg) refers to a branch from the lateral fissure (ltf) into the inferior frontal gyrus (IFG) of the human. Identified by dissection, it is embedded within the opercular part of the IFG (IFGop) ( Ono-1990; Ture-1999 ). In some individuals it separates the IFGop from the more caudal portion of the IFG ( Duvernoy-1992 ).
      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 27 Aug 2024.
