Correlation between modulation of the N45 amplitude by alprazolam and zolpidem (Experiment 1). A significant correlation was found between modulation of the N45 amplitude by alprazolam (x-axis) and modulation of the N45 amplitude by zolpidem (y-axis) (Spearman correlation coefficient, r2 = 0.29, p = 0.014).
