  1. Abbreviations: ATR, anterior thalamic radiation; CST, corticospinal tract; FA, fractional anisotropy; FMA, forceps major; IFOF, inferior fronto-occipital fasciculus; ILF, inferior longitudinal fasciculus; L, left; MD, mean diffusivity; R, right; SLF, superior longitudinal fasciculus; SLFt, temporal division of the superior longitudinal fasciculus; UF, uncinate fasciculus; WM, white matter.
  2. Peak voxel of each WM cluster is shown. Age and Raven’s Progressive Matrices score were included as covariates using a statistical threshold of P<0.05 after family-wise error correction. The coordinates were in Montreal Neurological Institute (MNI) space.
