Unilateral hand movement modulates phase-amplitude coupling (PAC) only at the GPi contralateral to the moving body side. (A) Average comodulogram (MI values) for the cohort at bilateral GPi during rest and movement conditions. (B) Comparison of average PAC values at different frequency bands during rest (gray) and movement (red) indicates significant suppression of the PAC only at the GPi contralateral to the movement side. Asterisk signs (*) indicate statistical significance of the difference between the two conditions as tested by Wilcoxon signed-rank test and corrected for multiple comparisons (P < 0.05). Each box contains the interquartile range and whiskers extend to the highest and lowest observations.
