Gyrus Frontalis Superior, Anterior View

Description

Oriented anteriorly, this 3D brain rendering emphasizes the superior frontal gyrus (gyrus frontalis superior) along the superomedial aspect of the frontal lobe, with the highlighted cortex extending toward the interhemispheric fissure. Adjacent sulcal boundaries you would expect to appreciate in this projection include the superior frontal sulcus laterally and, toward the midline, the medial frontal surface continuous with the paracentral lobule near the superior margin. The precentral region lies posterior to this territory, and the frontal pole sits inferior and anterior relative to the highlighted convolution. An inverted presentation makes the relationship to the brainstem and cerebellum easier to track at the inferior aspect of the model. Clinically, the superior frontal gyrus is a frequent point of reference when teaching the medial extension of the motor network, since supplementary motor area (SMA) cortex occupies the medial superior frontal gyrus and anterior paracentral lobule just anterior to the primary motor leg area. Lesions here, including parasagittal meningioma, anterior cerebral artery territory infarct, or postoperative edema after interhemispheric approaches, can produce contralateral lower-extremity weakness and the classic SMA syndrome (transient akinesia and speech initiation difficulty in the dominant hemisphere). It is a clean cortical landmark. The anterior perspective also supports correlation with functional MRI and neuronavigation planning, where the medial frontal convexity must be distinguished from precentral gyrus proper. Neuroanatomy instructors can drop this asset directly into modules on frontal lobe gyri and sulci, the homunculus along the medial wall, and clinicopathologic correlation for ACA strokes and falx-based tumors. It also fits neurosurgical atlases and patient-facing materials explaining why parasagittal lesions often affect gait and motor initiation.
