Phonological awareness is correlated with AF microstructure in the core region of the AF after individual tracts are aligned. (A) The curved portion of the AF where crossing fibers cause decreased FA is not in register across subjects. (B) Aligning AF trajectories minimizes the confounds of crossing fiber tracts and allows for comparison of microstructural properties in anatomically equivalent regions of the tract across subjects. (C) In a 1-cm region of the tract anterior to the curved portion and posterior to the region where fibers branch toward cortex, FA is significantly negatively correlated with phonological awareness (r = −.36). (D) This correlation is driven by a positive correlation between RD and phonological awareness (r = .35).
