The research team of British scientists from University College London has been able to prove experimentally that the crossing fingers helps dull the pain.
Scientists have known for interesting experiment sheds light on the mechanism of sensitivity body: if at the same time applied to the index, middle and ring fingers of the subjects hot, cold and hot items, respectively, then the middle finger will feel unbearable burning, although he was actually attached to the cold object. This experience is known in physiology as “illusion grill».
Scientists attached to the fingers experiment participants special equipment to create the sensation of cold and heat. The effect was like a trick “grill illusion.” The subjects felt pain not related to physical damage to the skin.
The researchers found when participants experience crossed the middle finger with the index or ring, feeling the pain disappeared.
Soreness is returned if the researchers cooled the ring and index fingers of the subjects. Moreover, the impression arises even when the index finger with a cold plate crossed with the middle finger so that it is between the middle and ring. On the other hand – if the middle finger with a cold plate with cross index or ring, the pain will arise.
Patrick Haggard, managing this project, came to the conclusion that part of the pain sensation can be controlled by a conventional moving body parts ratio to another. British scientists intend to investigate this phenomenon in more detail and to develop methods of pain relief not only in phantom, but with very real chronic pain.
