SCC	0.32*	0.41*	0.39*	0.38*	0.41*

The sign following the data in Table 4 indicates the relationship with the change of the corresponding data in Table 1. # indicates an increase with respect to the data in Table 1, * represents a decrease, and † indicates no change. BCC: Body of corpus callosum; CGG: cingulum; PSC1: primary somatosensory cortex 1; PSC2: primary somatosensory cortex 2; PSC3; primary somatosensory cortex 3; PMC: primary motor cortex; SAC; somatosensory association cortex; SCC: splenium of corpus callosum; SLF: superior longitudinal fasciculus.
