'Touch without touch, just by the power of thought!!!

How would you feel if an object without touching it to grab it with your hand, but only with the power of the mind? If you feel its texture, as if touched by a virtual hand, using the "electric" power of your mind?
  
No, there is a scene from science fiction, but the result of experimental research carried out with the help of technology from an international team of scientists.
  
For now, researchers were able to train two macaques monkeys to "catch" with a virtual hand various objects and "feel" the texture just with the 'electric' power of their minds.
  
Lead researcher Miguel Nikolelis, head of the
center Nefromichanikis Duke University in the U.S., is known for his studies in "reading" the brain of monkeys, as it is he who has previously failed to teach them to control the movements of a virtual hand the computer or operating prostheses (the video).Move the virtual hand with the power of thought!
  
This time went a step further. So apart from movement, and succeeded in the sense of touch, without touching, only through the power of thought! As stated in their study, published in the journal «Nature», the researchers introduced two macaques brain electrodes in areas related to the execution of voluntary movements and the processing of sensory stimuli, respectively.
  
Then, the two monkeys were trained to use only their brain to move a virtual hand on the computer screen and "touch" with what various objects. The electrodes were mounted in the motor cortex recorded by electrical signals, intended motion of monkeys and broadcast the information in the computer software.
  
Each time the virtual hand touches the objects on display electrical signals transmitted from the program in the somatosensory cortex of animals, giving information on how they would feel in their hands this object if caught really.
