(A) Mean between-subject coefficients of variation (CV) for each calculated contrast for both gray matter (GM) and white matter (WM). Between-subject CV values represent the mean ± standard error of the mean across the 12 participants (averaged over the two time points). (B) Mean within-subject CV for each calculated contrast for both GM and WM. Within-subject CV values represent the mean ± standard error of the mean between the two time points (averaged across the 12 participants). (C) Mean percent difference for each calculated contrast for both GM and WM. Percent difference represents the mean ± standard error of the mean between the two time points (averaged across the 12 participants).
