middle frontal gyrus (MFG)
The term middle frontal gyrus refers to a convolution of the frontal lobe identified by dissection. In the human it is located on the dorsolateral surface between the superior frontal sulcus, which separates it from the superior frontal gyrus, and the inferior frontal sulcus, which separates it from the inferior frontal gyrus caudally; the frontomarginal sulcus separates it from the frontomarginal gyrus rostrally.Caudally it is separated from the precentral gyrus by the precentral sulcus. In the macaque it extends from the angle of the arcuate sulcus to the frontal pole; it is bounded by the superior limb of the arcuate sulcus dorsally and by the principal sulcus ventrally.
Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).
Also known as: middle frontal gyrus, Gyrus frontalis medius, Gyrus frontalis medialis (Winters), intermediate frontal gyrus, Gyrus frontalis secundus, Gyrus F2, medial frontal gyrus of Mai
