An Anatomical Presentation Of The Brodmann Areas In Superior View

Description

Dorsal cerebral hemispheres fill the frame in superior view, with the interhemispheric (longitudinal) fissure dividing left and right and the falx cerebri implied deep to the midline. The animation sweeps along the central sulcus to localize the precentral gyrus (primary motor cortex, classically BA 4) immediately anterior to it and the postcentral gyrus (primary somatosensory cortex, BA 3, 1, 2) immediately posterior. As the sequence progresses posteriorly and laterally, labeled fields extend across the superior parietal lobule and around the intraparietal sulcus, clarifying how parietal association territories (commonly BA 5 and 7) relate to the primary sensory strip at the crown of the hemisphere. Boundaries track gyral crests and sulcal banks rather than arbitrary blocks. Clear and orderly. Top-down Brodmann mapping matters when you need to translate between cytoarchitectonic nomenclature and the surface landmarks used in operative planning, EEG topography, and functional MRI reporting. Lesions near the precentral gyrus can present with contralateral weakness in a somatotopic pattern, while infarcts or tumors involving the postcentral gyrus produce focal cortical sensory loss, and the animation’s stepwise labeling helps link those deficits to a specific gyrus on the superior convexity. Parietal involvement has its own clinical fingerprints, including apraxia and visuospatial dysfunction, and seeing BA 5 and 7 expand across the superior parietal ridge makes those associations easier to teach than a static diagram. Use this sequence in neuroanatomy and neurophysiology teaching, in neurosurgical education on cortical landmarks for craniotomy planning near the central sulcus, or in textbooks and slide decks that standardize Brodmann terminology across imaging and clinical neurology.
