a) As demonstrated in the main text, there was a significant increase in theta-band phase coherence between mid-frontal (Cz) and motor (C4) sites during the motor action to initiate the trial after errors vs. correct responses (mean phase locking value=.08). b) This enhancement in phase consistency with mid-frontal areas was not observed with an intermediate electrode (C2), and in fact the directionality was reversed (magenta area: mean phase locking value=-.02). This pattern demonstrates that the mid-frontal – motor coherence observed in (a) is not due to volume conduction, as the intermediary site would be enhanced in that case.
