The Brodmann Areas Of The Human Brain In Posterior View

Description

Posterior cerebral hemispheres fill the frame as the animation holds a true dorsal-posterior orientation, centering the occipital lobes inferiorly and the parietal lobes superiorly around the parieto-occipital region. Brodmann area boundaries appear sequentially over the cortical surface, tracking gyral and sulcal contours across the lateral convexities and toward the midline near the occipital pole. The calcarine territory associated with primary visual cortex (area 17) is referenced at the occipital pole, with adjacent extrastriate regions (areas 18 and 19) spreading laterally. Superiorly, parietal association cortex labels populate the superior parietal lobule and adjacent posterior parietal cortex (commonly areas 5 and 7). Cortical parcellation by Brodmann remains a common shorthand in neurology, neurosurgery, and neuroimaging reports, because the numbering system maps reasonably well to functional territories and to many lesion patterns. Posteriorly, distinguishing primary visual cortex (17) from extrastriate cortex (18, 19) supports clinicopathologic correlation in occipital infarcts and contusions, where homonymous visual field defects, visual agnosias, or alexia patterns depend on which belts are involved. Animated appearance of borders and numbers reduces the usual ambiguity of a single labeled plate, letting the viewer follow how each area sits relative to the occipital pole and posterior parietal convexity as the map builds. Use this animation in neuroanatomy and systems neuroscience teaching, as a figure asset for radiology or neurology texts that reference “BA 17–19” or posterior parietal areas, and as orientation material for fMRI or EEG/MEG source localization discussions that report activations in Brodmann terms. It also fits preoperative conference slide decks when documenting tumor margins or cortical stimulation results near visual association cortex.
