Summary of 1 mm3 voxels within major white matter fiber tracks (corresponding to blue ROIs from Fig. 2). The number of voxels within each lobe of the brain is listed. Key: Ant_Thal_Rad, anterior thalamic radiations; CC, corpus callosum; Cing_Cing_-Gyr, cingulum of cingulate gyrus; Cing_Hipp, cingulum of hippocampus; CS, corticospinal; FA, fractional anisotropy; IFOF, inferior frontal occipital fasciculus; ILF, inferior longitudinal fasciculus; L, left; R, right; ROIs, regions of interest; SLF, superior longitudinal fasciculus.
