Comparison of the averaged ITCs (A, B) and laterality indices of ITCs (C) between different click train frequencies at 20 − 83.3 Hz. A Temporal changes in mean ITCs across the five monkeys in response to 20, 40, 58.8, and 83.3 Hz click trains. Error bars indicate SEM in each time point. B Comparison of mean ITCs during 300 ms from 150 to 450 ms after stimulus onset for five monkeys in response to 20, 40, 58.8, and 83.3-Hz click trains at each electrode. C Comparison of mean laterality indices based on ITCs. Ant (blue), (F4-F3)/(F4 + F3); Mid (orange), (C4-C3)/(C4 + C3); Post (gray), (P4-P3)/(P4 + P3). An asterisk and double asterisks indicate significant differences (*p < 0.05, **p < 0.01, Tukey HSD test). Error bars represent SEMs
