Examples of time-frequency maps for the first condition from one subject at three electrode locations. RRR, RLR, LFL, and FRL indicate [right hand]–[right hand]–[right hand], [right hand]–[left hand]–[right hand], [left hand]–[right foot]–[left hand], and [right foot]–[right hand]–[left hand], respectively. Blue represents ERD and red represents ERS. The first and second vertical lines represent the onset and end of MI, respectively. Time 0 represents the time point of cue offset
