precentral operculum
Acronym: PrGOp
The term precentral operculum refers to the ventrolateral lip of the precentral gyrus, which overlies the insula and is bounded by the lateral fissure. Its boundary with the insula is the superior limiting sulcus ( Ture-1999 ). Defined by dissection, it is part of the frontal operculum of the human ( Roberts-1970 ), the guenon ( Mauss-1908 ) and the macaque ( NeuroNames ). It is not present in the smooth cerebral cortex of rodents.
