<P> The total number of long range fibres within a cerebral hemisphere is 2 % of the total number of cortico - cortical fibers ( across cortical areas ) and is roughly the same number as those that communicate between the two hemispheres in the brain 's largest white tissue structure , the Corpus callosum . According to Schüz and Braitenberg note `` As a rough rule , the number of fibres of a certain range of lengths is inversely proportional to their length . '' </P>
