superior frontal gyrus

superior frontal gyrus (SFG)

The term superior frontal gyrus (SFG) refers to the topologically defined convolution of the frontal lobe (FLB) that is located on the dorsal surface facing the longitudinal fissure (lgf). In the human it is bounded caudally by the precentral gyrus (PRG). It extends rostrally to the superior frontopolar gyrus (FPGs). On the mesial surface it is separated from the anterior cingulate gyrus (CGGa) by the cingulate sulcus (cgs). On the dorsolateral surface it is separated from the middle frontal gyrus (MFG) by the superior frontal sulcus (sfrs) ( Mai-1997 ). In the macaque, the SFG extends from the spur of the arcuate sulcus (sas) to the frontal pole (frp). The dorsolateral and medial boundaries are the same as in the human, except for a short ill-defined boundary with the straight gyrus (SRG) where the cgs ends short of the frontal pole (frp) ( Martin-2000 ). The macaque also has a superior precentral dimple (spd) located anterior to the central sulcus (cns) on dorsal surface of SFG that is not present in the human ( Bonin-1947 ). Histologically, the SFG is neocortex (Brodmann-1909). Equivalent structures are not found in the smooth cerebral cortex of the rat or mouse ( NeuroNames ). Final 26 Mar 2025.

Models Where It Appears

Structural CNS Model - Macaque

Brain structures of the macaque are illustrated in BrainInfo’s NeuroMaps macaque brain atlas. Structures are grouped by proximity in a hierarchy corresponding to the central nervous system hierarchy of NeuroNames ( Bowden-1995 Martin-2000 ). Structures in the NeuroMaps atlas are based on the segmentation of an MRI of the brain of a 3-year old male rhesus macaque (Macaca mulatta). The atlas is most useful for targeting structures for implantating electrodes and chemtrodes. Updated 29 Oct 2025.
