A group of Swiss and German researchers led by Olaf Blanke of the Federal Polytechnic School Lausanne (Ecole Polytechnique Fédérale de Lausanne) and regardless them to Henrik Ehrsson from Swedish Carolinsky Institute (Karolinska Institutet) was able to call in subjects volunteers feeling out of the body. It turned out that out of body sensations appear when the tactile and visual mismatch information, reports the BBC.
Out-of-body experience is reported by many people. These sensations arise with clinical death, in meditation, with some substances, for example, with intramuscular injection of ketamine, with beyond physical exertion and some special exercise, prolonged lack of sleep, as well as with some neurological disorders. Put on the subjects special glasses to which a three-dimensional image of them was transmitted themselves, filmed by a camera located behind his back. Picture served with a certain delay in time, which could change. To volunteers participating in the experiment periodically touched with a fountain pen or hand. When the researcher touched the back of the subject, the subject saw touching your “virtual” back or at the same moment, when touching his real body, or with some delay. Subjects noted that “touching” the “virtual back”, which it was seen with some delay, even felt more real than the touch that actually happened. At the subjects had a feeling that the virtual body is their own body that they left. When the camera switched on the back of a dummy that looked like a test subject, and the man saw touching the back of a mannequin, while in reality no one touched the person, the subject reported that he feels the touch. After the image on the glasses turned off, and the person was offered to take a step back, he was wrong relative to its real position in space – some time he was, as it were, in the place where his “was” virtual body. Dr. Henrik Ehrsson, noted that the subjects perceived their visible image of their body as their real body that they left. They experienced anxiety (expressed, in particular, in increased perspiration) when struck with a hammer to the place where, as it seemed to a person, is his virtual body. Researchers believe that sensations “bodies” with out-of-body experience are associated with tactile sensations, and “souls” or “consciousness” – with the visual. When these two streams of sensations there is an illusion of exiting the body. Researchers believe that in addition to theoretical research can have applied value. In particular, the feeling of virtual body, as your own, can be used in the development computer games of a new generation: in such a game a man virtual body can be fully integrated into the gaming space.
