Superior Frontal Gyrus Of The Brain (Frontal View)

Description

Superior frontal gyrus occupies the dorsomedial crown of the frontal lobe, seen here from a frontal (anterior) perspective at the upper aspect of each cerebral hemisphere. Medially it approaches the interhemispheric fissure and frontal pole, while inferiorly it is separated from the middle frontal gyrus by the superior frontal sulcus. Posteriorly the gyrus continues toward the precentral region, with the precentral sulcus and central sulcus lying further posterior in the same sagittal plane. Bilateral symmetry is emphasized. Cortex along the superior frontal gyrus overlaps Brodmann areas 6, 8, 9, and 10, linking it to supplementary motor planning on the medial surface and to dorsolateral prefrontal networks for working memory, attentional set shifting, and executive control. Focal lesions from anterior cerebral artery territory infarct, parasagittal meningioma, traumatic contusion of the frontal pole, or infiltrating glioma can present with abulia, impaired initiation, or subtle deficits in planning that are easy to miss without a firm gyral map. A frontal viewpoint helps orient the viewer to the gyrus as the uppermost longitudinal fold of the frontal lobe and clarifies its relationship to the midline, a frequent source of left right confusion when correlating surface anatomy with axial MRI and coronal CT. Use this illustration for introductory neuroanatomy and neuroscience courses when teaching frontal lobe sulci and gyri, and for figure plates in neurology or neurosurgery texts that reference superior frontal gyrus involvement in executive dysfunction, seizure onset zones, or parasagittal mass effect. It also supports clinical documentation and patient education when localizing a lesion to the anterior frontal convexity versus the parasagittal region.
