Structural Morphology Of The Brodmann Areas, Medial View

Description

Brodmann areas are organized across the medial surface of a cerebral hemisphere, with cytoarchitectonic borders tracking familiar sulci and gyri. Along the cingulate gyrus, areas 24 and 32 follow the corpus callosum in an anteroposterior arc, separated superiorly from medial frontal cortex by the cingulate sulcus. Superior to the cingulate, the paracentral lobule contains the medial continuation of the precentral and postcentral gyri, where area 4 lies anterior to the central sulcus and areas 3, 1, and 2 lie posteriorly, with area 6 extending rostrally onto the medial superior frontal gyrus (supplementary motor region). Calcarine and parieto-occipital sulci at the posterior pole typically anchor occipital mapping, including area 17 around the calcarine fissure. Medial Brodmann mapping matters because many high-yield clinical syndromes localize here. Infarction in the anterior cerebral artery territory often affects the paracentral lobule, producing contralateral leg-predominant weakness and sensory loss that correlate cleanly with areas 4 and 3, 1, 2 on the medial bank of the central region. Cingulate cortex parcellation (areas 24, 32, 23, 31) also supports discussions of pain affect, attention, and limbic circuitry, and it frequently appears in neurosurgical planning for cingulotomy targets or in seizure workups involving mesial frontal and cingulate epileptogenic zones. Boundaries keyed to sulcal landmarks make the still perspective easy to align with gross anatomy and with medial-surface MRI teaching points. Neuroanatomy and neuropsychology courses use this illustration to teach cortical localization without relying on a lateral surface alone, and it fits well in atlases, review chapters, and slide decks on functional neuroanatomy. Clinical teams can also drop it into stroke localization handouts and preoperative counseling materials for mesial frontal or cingulate approaches.
