Mean (MD), axial (AD), and radial (RD) diffusivity and fractional anisotropy (FA) for each tract. FMaj = Forceps Major, FMin = Forceps Minor, ATR = Anterior Thalamic Radiation, CAB = Cingulum Angular Bundle, CCG = Cingulum Cingular Bundle, CST = Corticospinal Tract, ILF = Inferior Longitudinal Fasciculus, SLFP = Superior Longitudinal Fasciculus Parietal part, SLFT = Superior Longitudinal Fasciculus Temporal part, UNC = Uncinate Fasciculus. Bonferroni-corrected at factor of 18, p values are significant p = 0.003.
