Network representation where nodes are human cortical regions and edges indicate existing fiber tracts detected through diffusion tensor imaging. This axial view shows connectivity within hemispheres (top: frontal lobe; bottom: occipital lobe) as well as callosal fibers between hemispheres (left: left hemisphere; right: right hemisphere). Note that some sections were removed to get a better view on the underlying connectivity. The 2D plane of the cut is indicated by white boundaries around the cortical surface and affected fibers.
