Reinforcement magnitudes of a given trial modulate alpha/low beta activity during the next trial’s joystick movement. (A) Across time-frequency space, Pearson’s correlation coefficients between reinforcement magnitudes and task-related changes in LFP power are shown. Time point zero corresponds to response onset; average response duration is depicted by a vertical line at 669 ms. The frequency range spans 5 to 80 Hz. Correlations were tested for significance with a cluster-based approach described by Maris and Oostenveld18. The borders of a significant cluster are highlighted by a black line. (B) Average LFP power changes within the significant cluster of panel A relative to baseline are shown for different reinforcement magnitudes.
