Alterations in component diffusivities in aMCI after controlling for WM atrophy. The anatomic underlay and registered average FA skeleton are described in the Figure 1 legend. The top panel displays regions of increased in DR (blue) or decreased in DA (yellow) that overlap with regions of decreased FA (red) in the aMCI group. The bottom panel displays regions of increased DR (blue) or decreases in DA (yellow) that do not overlap with regions of decreased FA in the aMCI group. The numbers below coronal sections represent y coordinates in MNI space. Note: ALIC, anterior limb of the internal capsule; CING, cingulum; CST, corticospinal tracts; UNC, uncinate fasciculus; SLF, superior longitudinal fasciculus; ILF, inferior longitudinal fasciculus.
