The differences show up in a number of ways: the effects of localized brain damage, regional activity patterns exposed when the brain is examined using functional imaging techniques, connectivity with subcortical areas, and regional differences in the cellular architecture of the cortex . Neuroscientists describe most of the cortex--the part they call the neocortex--as having six layers, but not all layers are apparent in all areas, and even when a layer is present, its thickness and cellular organization may vary . Scientists have constructed maps of cortical areas on the basis of variations in the appearance of the layers as seen with a microscope . One of the most widely used schemes came from Korbinian Brodmann, who split the cortex into 51 different areas and assigned each a number (many of these Brodmann areas have since been subdivided). For example, Brodmann area 1 is the primary somatosensory cortex, Brodmann area 17 is the primary visual cortex, and Brodmann area 25 is the anterior cingulate cortex . </P>
