triangular part of the inferior frontal gyrus
Acronym: IFGTr
The term triangular part of the inferior frontal gyrus refers to one of three parts of the inferior frontal gyrus that overlie the insula and form the lower boundary of the gyrus with the lateral fissure. Its boundary with the insula is the superior limiting sulcus ( Ture-1999 ). Defined by dissection, it is the middle of the three. The others are the orbital part of the inferior frontal gyrus and the opercular part of the inferior frontal gyrus. A component of the frontal operculum in the human ( Carpenter-1983 ), it is not present in macaques or rodents.
