diagonal sulcus
Acronym: dias
The term diagonal sulcus refers to a branch from the lateral fissure into the inferior frontal gyrus of the human. Defined by dissection, it is embedded within the opercular part of the inferior frontal gyrus ( Ono-1990; Ture-1999 ). Some authors indicate that it separates the opercular part from the more caudal portion of the inferior frontal gyrus ( Duvernoy-1992 ). Branches from the lateral fissure are not found in the macaque, nor is the lateral fissure itself found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).
