T2 values estimated by using the direction-averaged method, AMICO-T2 and COMMIT-T2. The analysis is performed on the arcuate fasciculus (AF), cingulum (CG), inferior fronto-occipital fasciculus (IFOF), inferior longitudinal fasciculus (SLF), optic radiation (OR), superior longitudinal fasciculus (SLF), and uncinate fasciculus (UF). Comparison is performed considering the average along all voxels where the bundle is defined, where multiple populations occurred, and in voxels where only one population is present (by defining a fractional anisotropy (FA) threshold = 0.7, computed by fitting a diffusion tensor model). Bar height indicates the mean value and whiskers represent the standard deviation across voxels.
