Brodmann areas Cerebral cortex

different parts of cerebral cortex involved in different cognitive , behavioral functions. differences show in number of ways: effects of localized brain damage, regional activity patterns exposed when brain examined using functional imaging techniques, connectivity subcortical areas, , regional differences in cellular architecture of cortex. neuroscientists describe of cortex—the part call neocortex—as having 6 layers, not layers apparent in areas, , when layer present, thickness , cellular organization may vary. scientists have constructed maps of cortical areas on basis of variations in appearance of layers seen microscope. 1 of used schemes came korbinian brodmann, split cortex 51 different areas , assigned each number (many of these brodmann areas have since been subdivided). example, brodmann area 1 primary somatosensory cortex, brodmann area 17 primary visual cortex, , brodmann area 25 anterior cingulate cortex.
