where is white matter located in the brain
White matter 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.[4] According to SchÃ¼z and Braitenberg note "As a rough rule, the number of fibres of a certain range of lengths is inversely proportional to their length."[4]
