Reinforcement magnitudes modulate beta activity during feedback presentation. (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 feedback onset, time-point 1.2 to feedback offset. The frequency range spans 5 to 80 Hz. Correlations were tested for significance with a cluster-based approach described by Maris and Oostenveld18. 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.
