Regional differences in cerebral asymmetries of human cortical white matter

► Rightward and leftward asymmetry in parietal and occipital pathway FA, respectively. ► Rightward asymmetry in parietal and frontal pathways for parallel diffusion. ► Leftward asymmetry in temporal and occipital pathways for perpendicular diffusion. ► Different patterns of asymmetry may reflect differences in white matter microanatomy.
