Overall, there are 58 deep white matter fiber tracts from the association, cerebellar, commissural and projection tracts, and 16 superficial tract categories according to the brain lobes. Except for the 7 corpus callosum (CC) tracts and the middle cerebellar peduncle (MCP) tract that cross the hemispheres (C), others are hemispheric (LR).
