The Structural Morphology Of The Brodmann Areas In Medial View

Description

Medial hemispheric cortex fills the frame, with Brodmann areas mapped across the cingulate gyrus arching superior to the corpus callosum and continuing posteriorly toward the isthmus and precuneus. The animation tracks along the callosal sulcus and cingulate sulcus, then lifts superiorly onto the paracentral lobule on the medial surface, where the central sulcus and marginal ramus of the cingulate sulcus outline the medial sensorimotor strip. Color-coded fields sequentially resolve into familiar territories: anterior cingulate (BA 24 and 32), posterior cingulate (BA 23 and 31), and medial portions of primary motor and somatosensory cortex (BA 4 and 3, 1, 2) around the paracentral lobule. Boundaries sharpen over time. Clinically, these medial Brodmann relationships matter when symptoms localize to leg-predominant motor or sensory deficits, since infarcts in the anterior cerebral artery territory often involve the paracentral lobule while sparing lateral face and arm representations. The stepwise highlighting makes it easier to correlate sulcal landmarks to cortical areas than a single plate, a common pain point when reading operative reports, interpreting medial fMRI activations, or teaching why cingulotomy targets anterior cingulate cortex rather than adjacent supplementary motor regions. Small shifts in sulcal position change the map. Use this animation in neuroanatomy and neuroscience curricula to teach cortical parcellation on the medial surface, in neurology lectures on ACA stroke syndromes and focal seizure semiology, or in figure supplements for papers discussing cingulate network nodes and medial motor cortex activations.
