superior frontal gyrus
Acronym: SFG
The term superior frontal gyrus refers to the convolution of the frontal lobe that is located on the dorsal surface facing the longitudinal fissure. In the human it is bounded caudally by the precentral gyrus, from which it is separated by the superior precentral sulcus; it extends rostrally to the superior frontopolar gyrus. On the medial surface it is separated from the anterior cingulate gyrus by the cingulate sulcus. On the dorsolateral surface it is separated from the middle frontal gyrus by the superior frontal sulcus ( Mai-1997 ). In the macaque it extends from the spur of the arcuate sulcus to the frontal pole. The dorsolateral and medial boundaries are the same as in the human, except for a short ill-defined boundary with the straight gyrus where the cingulate sulcus ends short of the frontal pole ( Martin-2000 ).
     Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ).
