Brain's Medial Frontal Gyrus, Medial View

Description

Medial frontal gyrus occupies the superior medial surface of the frontal lobe, continuing anterior to the paracentral lobule and superior to the cingulate sulcus in a mid-sagittal, medial view. Its cortical ribbon forms the internal aspect of the superior frontal convolution, with the interhemispheric fissure immediately medial and the cingulate gyrus curving inferiorly toward the corpus callosum. Posteriorly, the medial frontal gyrus blends into the paracentral lobule near the marginal ramus of the cingulate sulcus, a practical landmark for separating medial frontal association cortex from the medial primary motor and somatosensory representations of the lower limb. Clinically, this territory overlaps the supplementary motor area and medial prefrontal networks, so lesions can present with abulia, impaired initiation, or akinetic mutism, while epileptogenic foci here often produce brief tonic posturing and speech arrest. An anterior cerebral artery (ACA) infarct classically affects medial frontal and paracentral regions, correlating with contralateral leg-predominant weakness and gait disturbance, and the medial view clarifies why these deficits track the interhemispheric vascular distribution rather than the lateral convexity. The fixed perspective also helps separate the medial frontal gyrus from the cingulate gyrus, a common point of confusion when learners rely only on lateral views. Neuroanatomy instructors can drop this illustration into modules on medial hemispheric landmarks, sulcal patterns, and functional localization, pairing it with sections on the cingulate sulcus, paracentral lobule, and callosal anatomy. Neuroscience publishers and clinical teams will find it well suited for figures on ACA stroke syndromes, medial frontal tumor localization, and preoperative counseling around supplementary motor area involvement.
