Abstract
The Rubber Hand Illusion (RHI) can be induced by synchronous brushing of a seen rubber hand and the subject’s real hidden hand. We sought to determine whether the RHI could be induced using one somatosensory modality and maintained using another. In 75 subjects, one of three modalities was used to induce the RHI: touch (brush), vibration (128Hz), or temperature (cooling). We then tested whether the illusion was maintained when only the rubber hand received stimuli from all modalities including kinesthesia (passive movement of arm). The RHI was successfully induced with touch, vibration and cooling modalities in 35 of 75 subjects. When only the seen rubber hand received a stimulus and not the hidden real hand, ownership persisted in 24 of 35 subjects who were successfully induced before. Our results may contribute to the understanding of the RHI and to the development of somatosensory neuroprosthetics.
