aAll analyses control for age at scan. 3-D renderings (right sagittal views) generated from deterministic tractography are shown for each WM tract of interest and whole-brain WM. Green fibers extend along anterior-posterior axis; red fibers along the medial-lateral axis; and blue fibers along the superior-inferior axis.
bStatistically significant under the frequentist framework at a Bonferroni-corrected level (P < 0.00625).
