Event-related potentials (ERPs) from 70 sequences were recorded in both Motor and Imagery tasks in 15 experimental participants. Due to noise on the trial-marker channel two participants had lower trial numbers, thus ERPs from only 50 sequences were extracted from the Motor task in one, while only 60 sequences were extracted from the Imagery task in another.
