Brodmann Area 7 Of The Human Human Brain (Lateral View)

Description

Brodmann area 7 occupies the cortex of the superior parietal lobule on the lateral surface of the cerebral hemisphere. Its gyral territory sits posterior to the postcentral gyrus and postcentral sulcus, superior to the intraparietal sulcus (which separates it from the inferior parietal lobule), and anterior to the parietal component of the occipital transition near the lateral end of the parieto-occipital region. From this lateral perspective, the field corresponds to the dorsal parietal convexity, lying superior to the posterior segment of the lateral sulcus and extending medially beyond the crown of the hemisphere where it continues toward the precuneus. A dorsal association cortex. Area 7 integrates somatosensory input with visual and proprioceptive information to support visuospatial attention and visually guided reaching, so lesions in this region can present with optic ataxia or contribute to Balint syndrome (simultanagnosia, ocular apraxia, optic ataxia) when bilateral, or with contralateral hemispatial neglect when the right parietal lobe is involved. The lateral view is the one most clinicians and educators reach for when correlating bedside findings with a parietal cortical target, because it preserves the relationship between the superior parietal lobule and the intraparietal sulcus, a frequent landmark in functional neuroanatomy and neurosurgical mapping. Precise sulcal boundaries matter here. Neuroanatomy and neuroscience courses can use this illustration to anchor Brodmann map teaching on the parietal convexity, and neurology or neurosurgery texts can pair it with discussions of dorsal stream dysfunction, posterior parietal stroke syndromes, and cortical localization for visuomotor deficits. It also fits slide decks for fMRI or EEG source modeling that references the superior parietal lobule and intraparietal sulcus as coordinate landmarks.
