Figure 2. Significant interactions identified by the repeated-measures ANOVA performed on the coherence Z-scores across all participants (n = 10). (A) Averages (± SEM) for the condition (control or local anesthetic) by pre-load interaction (n = 50). (B) Averages (± SEM) for the condition by frequency interaction (n = 40). Pairwise comparisons performed with Tukey’s HSD.
