Bilateral rubber hand illusion induced by unilateral visuotactile stimulation

The rubber hand illusion involves the sense of body ownership of a fake hand. We showed that concurrent visuotactile stimuli to <i>unilateral</i> rubber and real hands can induce the embodiment of <i>bilateral</i> rubber hands when both rubber hands are positioned on the table. This phenomenon indicates that the brain has an integrated representation of the sense of body ownership for both hands.
