abstract = {Neurophysiological accounts of human volition are dominated
by debates on the origin of voluntary choices but the neural
consequences that follow such choices remain poorly
understood. For instance, could one predict whether or not
an action was chosen voluntarily based only on how that
action is motorically executed? We investigated this
possibility by integrating scalp electroencephalograms and
index-finger accelerometer recordings acquired while people
chose between pressing a left or right button either freely
or as instructed by a visual cue. Even though freely
selected and instructed actions were executed with equal
vigor, the timing of the movement to release the button was
comparatively delayed for freely selected actions. This
chronometric difference was six-times larger for the
β-oscillations over the sensorimotor cortex that
characteristically accompany an action's termination. This
surprising modulation of an action's termination by volition
was traceable to volition-modulated differences in how the
competing yet non-selected action was represented and
regulated.},
