Fig. 1.

Panels depict group differences in white matter microstructure measures of radial diffusivity (RD) and fractional anisotropy (FA) across specific tracts. A: RD values for the inferior fronto-occipital fasciculus (IFO), cingulum bundle (CG), uncinate fasciculus (UF), arcuate fasciculus (AF), optic radiations (OR). Significant differences are marked with p-values between groups. B: FA values for the same tracts as in (A), showing significant between-group differences. Error bars represent standard errors of the mean. Asterisk above bars indicate statistically significant differences between groups, as indicated by p-values (’∗‘: p ≤ .05; ‘∗∗‘: p ≤ .01; ‘∗∗∗‘: p ≤ .001).
