Modulation of MEPs during motor imagery. Mean MEP amplitudes recorded from the right opponens pollicis during the imagination of motor behaviors using the normal and reverse tools in both the goal and no-goal conditions. “Extend” and “flex” refer to the imagined movements of the participants' thumb. Values from individual participants are represented as line–symbol, whereas mean values of the group are represented as gray columns. p values from the relevant post hoc comparisons are given.
