The Human Brain's Brodmann Areas In Medial View

Description

Sweeping along the medial surface of the cerebral hemisphere, the animation tracks Brodmann areas arranged around the longitudinal fissure, from the frontal lobe at the genu of the corpus callosum back to the occipital pole. Area boundaries contour the cingulate gyrus superior to the corpus callosum, continue onto the medial aspect of the superior frontal gyrus and paracentral lobule, and extend posteriorly across the precuneus to the cuneus and calcarine cortex. Primary visual cortex (area 17) anchors the banks of the calcarine sulcus, with adjacent extrastriate territories (areas 18 and 19) radiating onto the medial occipital surface. Labels shift in sequence as the camera advances, keeping gyri and sulci as fixed landmarks while the cortical map updates. Brodmann mapping still matters because functional localization and clinicopathologic patterns often follow cytoarchitectonic, not purely gyral, borders. The medial view is where that becomes most obvious. Lesions involving the anterior cerebral artery territory commonly affect the paracentral lobule (areas 4 and 6), producing contralateral leg-predominant weakness, while infarcts or hemorrhage near the calcarine cortex can cause homonymous hemianopia or macular sparing depending on striate cortex involvement. An animated pass clarifies how areas 24 and 32 wrap the cingulate sulcus and how area 17 stays tethered to the calcarine fissure, relationships that are easy to lose in a single still. Use it for neuroanatomy and neuropsychology teaching when introducing cortical localization, for fMRI/EEG figure callouts that reference Brodmann areas, or for clinical education on medial hemispheric stroke syndromes and posterior cerebral artery visual deficits. It also slots cleanly into radiology and neurosurgery modules that correlate medial cortical landmarks with sagittal MRI and interhemispheric surgical corridors.
