Fig. 1.

Map of the fractional anisotropy (FA) differences between groups (patients < controls). The FMRIB58_FA (1 mm thick) template provided in FSL was used in all the figures. Top row: results are shown on top of the mean FA skeleton template created from all the participants’ images for this study. Bottom row: results are shown on top of the atlas of tracts probability Johns Hopkins University–International Consortium for Brain Mapping (threshold 0 mm and 1 mm thick) provided in FSL; different shades correspond to specific probability tracts in the left hemisphere: superior longitudinal tract, corticospinal tract, cingulum, anterior thalamic radiation, splenium of the corpus callosum, inferior longitudinal tract and inferior fronto-occipital tract.
