      abstract     = {The internal representation of the body emerges via the
                      integration of multisensory body cues. Sensory signal
                      transfer and the ability to integrate multisensory
                      information deteriorate significantly with increasing age.
                      However, there is little empirical evidence on age-related
                      changes in body representations based on multisensory
                      integration. Here, we used a standard paradigm for
                      evaluating body representations based on multisensory
                      integration, the rubber hand illusion, and compared the
                      amount of proprioceptive drift and changes in perceived body
                      ownership triggered by the integration of visual, tactile,
                      and proprioceptive cues between younger and older adults. To
                      account for potential age-related differences in the
                      temporal stability of the illusion, proprioceptive drift was
                      measured at five different time points. Our results show
                      that older adults used synchronous visuo-tactile cues
                      similarly to younger adults to update both the position of
                      their own hand, and their feeling of ownership over the
                      artificial hand. Independent of visuo-tactile synchrony,
                      older adults perceived their hand as closer to their body
                      than younger adults did, and showed a less stable
                      representation of this in-depth hand position. This
                      proprioceptive bias towards the body did not correlate with
                      the strength of the illusion. Our results indicate that the
                      integration of visual and tactile cues is largely preserved
                      in advanced age when used to update limb position, whereas
                      proprioception worsens with age. This may be linked to two
                      different pathways that underlie changes in body
                      representations over the life span.},
