Coronal (A), sagittal (B) and axial (C) illustrations of the tracts used in the tract-level analysis. Tracts were extracted with constrained spherical deconvolution (CSD)-based tractography from the diffusion weighted data of a single subject. Corticospinal tract (CST) = blue, splenium of corpus callosum (SCC) = white, anterior thalamic radiation (ATR) = yellow, inferior fronto-occipital fasciculus (IFO) = red, uncinate fasciculus (UNC) = cyan, inferior longitudinal fasciculus (ILF) = green, superior longitudinal fasciculus (SLF) = violet.
