In 2016, a group around John-Dylan Haynes in Berlin (Germany) determined the time window after the BP in which an intended motion could possibly be cancelled upon command. The authors tested whether human volunteers could win a “duel“ against a BCI (Brain Computer Interface) designed to predict their movements in real-time from observations of their EEG activity (the BP). They aimed to determine the exact time at which cancellation (veto) of movements was not possible anymore (the point of no return). The computer was trained to predict by means of the BP when a proband would move. The point of no return was at 200 ms before the movement. However, even after that, when a pedal was already set in motion, the subjects were able to reschedule their action by not completing the already started behavior. The authors pointed out in their report that cancellation of self-initiated movements had already been reported by Libet in 1985. Thus, the new achievement was a more precise determination of the point of no return.
