The Superior Frontal Gyrus (SFG) is a part of the Frontal lobe in the human brain. Situated superior to the Middle Frontal Gyrus, the SFG is involved in self-awareness and coordination of mental activity.

Anatomy

The Superior Frontal Gyrus extends from the frontal pole to the precentral sulcus, which separates it from the precentral gyrus. It is bounded laterally by the superior frontal sulcus. The medial part of the SFG is often referred to as the medial frontal gyrus.

Function

The SFG is involved in a variety of functions, including self-awareness and executive functions such as decision-making. It is also implicated in motor function, particularly the coordination of complex movements.

Clinical Significance

Damage to the Superior Frontal Gyrus can result in a variety of cognitive and motor deficits, including apraxia, dyscalculia, and frontal lobe syndrome. It is also implicated in several psychiatric disorders, including schizophrenia and major depressive disorder.
