  1. ALIC: anterior limb of the internal capsule, CG: cingulum, EC: external capsule, fornix, GCC: genu of the corpus callosum, PLIC: posterior limb of the internal capsule, SCC: splenium of the corpus callosum, CST: corticospinal tract, SLF: superior longitudinal fascicle, IFOF: inferior fronto-occipital fasiculus. AI: angle of primary eigenvectors. ANOVA was used to compare the difference between the three diffusion tensor templates. P1: Statistically significant differences between hFA template and T1normalized (after correction for multiple comparisons with the Bonferroni approach). P2: Statistically significant differences between T1normalized and hFAnormalized (after correction for multiple comparisons with the Bonferroni approach). P3: Statistically significant differences between FAnormalized and hFAnormalized (after correction for multiple comparisons with the Bonferroni approac.
