†
after adjusting for the effects of age. Cing = cingulum; CingHip = ventral leg of the cingulum; FMin = forceps minor (or genu); IFOF = inferior fronto-occipital fasciculus; ILF = inferior longitudinal fasciculus; UF = uncinate fasciculus. Significance: * = p < 0.05; ** = p < 0.01; *** = p < 0.001; **** = p < 0.0001.
