Anatomical terms of neuroanatomy

Themedial frontal gyrus is a continuation of thesuperior frontal gyrus from its most anterior border onto the medial surface of the hemisphere. The medial and superior frontal gyri are two of thefrontal gyri of thefrontal lobe. The portion on the lateral surface of the hemisphere is usually more or less completely subdivided into an upper and a lower part by an antero-posterior sulcus, the paramedial sulcus, which, however, is frequently interrupted bybridging gyri.

There is some evidence that it plays a role in executive mechanisms.[1]
