intermediate orbital gyrus
Acronym: IOrG
The term intermediate orbital gyrus refers to one of four orbital gyri on the ventral surface of the frontal lobe in the human. Defined on the basis of dissection and stains for Nissl substance, it is located between the medial orbital gyrus and the lateral orbital gyrus. It is separated from the posterior orbital gyrus by the, transverse orbital sulcus, the horizontal component of the orbital sulci ( Mai-1997 ). The comparable central portion of the orbital gyri in the frontal lobe of the macaque is occupied by the medial part of the lateral orbital gyrus ( Martin-2000 ). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).
