The article "Video ergo sum: manipulating bodily self-consciousness" by Bigna Lenggenhager, Tej Tadi, Thomas Metzinger, and Olaf Blanke explores the manipulation of bodily self-consciousness using virtual reality. The authors designed an experiment to induce out-of-body experiences in healthy participants by presenting a virtual body that was stroked synchronously or asynchronously with the participant's real body. The results showed that participants experienced a drift toward the virtual body, indicating a mislocalization of their own body to a position outside their physical body. This finding suggests that bodily self-consciousness and self-hood can be dissociated from one's physical body position. The study also found that the illusion was stronger when the virtual body was stroked synchronously with the participant's real body, and it was weaker when the virtual body was an object rather than a body part. The authors conclude that their findings support the idea that bodily self-consciousness and self-hood rely on similar visual-somatosensory integrative mechanisms as those used for body parts, and that these mechanisms may involve the temporoparietal junction. The study opens new avenues for investigating the neurobiological, functional, and representational aspects of embodied self-consciousness.The article "Video ergo sum: manipulating bodily self-consciousness" by Bigna Lenggenhager, Tej Tadi, Thomas Metzinger, and Olaf Blanke explores the manipulation of bodily self-consciousness using virtual reality.
