CCg: the genu of the corpus callosum; CCb: the body of the corpus callosum; CCs: the splenium of the corpus callosum; ALIC: the anterior limb of the internal capsule; PLIC: the posterior limb of the internal capsule; SLF: the superior longitudinal fasciculus; Cing: cingulum; Significant linear age correlations are bolded; rageN: association with age in normal-appearing white matter; rageW :association with age in whole white matter.
