Sometimes people in a completely empty room report that they feel someone’s strange, invisible presence. Some tend to believe that these are manifestations of the other world, perhaps ghosts. In a new study, scientists decided to find out that specifically affects human perception, forcing us Feel inexplicable fear. For his experiments they used a robot capable of creating in the human brain the illusion of the presence of a ghost, causing a few dozen healthy people the most terrible feeling. Feeling that the presence of someone nearby in an empty room most often occurs in people in a state of physical exhaustion or with mental and neurological disorders. However after conducting one of these experiments 30 percent healthy participants spontaneously informed that they not only feel someone presence, but also feel that someone is touching them. At the participants experiment were blindfolded and wearing headphones. They were between two components of the robot, one of which reads the movements human hands, and the other (located behind the back of the participant) them completely repeated, touching his back. That is, man with his back he felt the reproduced movements of his own hand. All was pretty predictable until the researchers decided program the robot for a short delay between actions participants and the reproduction of these actions. The Phantom Experience Delay between own actions and sensory the signals caused the participants not only confusion, but also feeling of fear. The brain of people was faced with an impossible situation, in which sensory and motor signals do not match. For some participants fear was so strong that they asked stop the experiment. Scientists believe that the results of this experiences demonstrate a balance between the brain mechanisms of people. These mechanisms generate their own human experience, and any distortions can provoke the most strange sensations and reactions. A ghost in the brain. Experimental sensations. healthy people were reminded of the sensations of patients with mental disorders of either healthy people, but in extreme conditions. This confirms that a sensation like presence a ghost caused, quite possibly, by a modified perception of the brain own body. To explore the brain structure of this illusion, researchers examined 12 patients with clear signs brain damage. They all told that they periodically see inexplicable weird shadows, possibly ghosts. Researchers directly link the illusory perception of the brain (hallucinations) with its defeat in three areas: temporal, insular and frontoparietal bark. They are confident that the results of this experience will help us more. understand the nature of hallucinatory signs of such a severe diseases like schizophrenia.
