The association of RA with regional brain structures and white matter microstructures. (a–c) show the association of RA with regional brain structures (a) cortical volume, cortical surface area, cortical thickness; (b) subcortical volume and subcortical intensity; (c) FA and MD. (d) shows the significant mediating effect of regional brain structures in the association of RA and processing speed. (e) shows the significant mediating effect of white matter microstructures in the association of RA and processing speed. ATR, anterior thalamic radiation; CC, corpus callosum; DE, direct effect; FA, fractional anisotropy; FM, forceps minor; IE, indirect effect; lh, left hemisphere; MD, mean diffusivity; Prop.med, proportion of mediation; PTR, posterior thalamic radiation; RA, relative amplitude; rh, right hemisphere; SLF, superior longitudinal fasciculus; STR, superior thalamic radiation; Ventral DC, Ventral Diencephalon; vol, volume.
