In a series of experiments in the 1980s, Benjamin Libet studied the relationship between conscious experience of volition and the BP e.g. and found that the BP started about 0.35 sec "earlier" than the subject's reported conscious awareness that "now he or she feels the desire to make a movement." Libet concludes that we have no free will in the initiation of our movements; though, since subjects were able to prevent intended movement at the last moment, we do have the ability to veto these actions ("free won't").
