Ученые научат слепых видеть путём стимуляции их мозга (видео) Scientists from the University of Washington announced the successful conduct of an experiment in which participants could navigate through virtual mazes, not looking directly at the monitor, but using direct brain stimulation. Specialists intend to continue to develop the technique, bringing it to the end of touch prosthetics technology, which will help visually impaired people navigate the real world and interact with a new, gaining momentum – virtual. Five players who participated in the research of the system interacted with the game through a process known as transcranial magnetic stimulation (TMS), where magnetic coils are located in the back of the skull and safely / painlessly stimulate certain parts of the head brain. This method has already demonstrated its potential in the treatment of migraine, learning, improving memory, and also in establishing communication between one brain and another. In this case, the brains of the participants were stimulated by directing them through 21 simple labyrinths in the game. Each step of the path offered a binary choice: to go straight or go down the stairs. When an obstacle appeared in front of the player, the device stimulated the brain and created the visual artifact “phosphene” – a visual sensation that a person experiences without exposure to light on the eye. This was a signal that you need to go down the stairs. If luminous dots did not appear, the subject continued to move forward. Using this method, players managed to take 92% of the correct steps. The control group, which was offered a TMS placebo, managed not to make mistakes in only 15 percent of cases of movement through the maze. \- says co-author of the study, Andrea Stocco: “But in the end, we can replace the equipment with something that works with real applications.” Researchers say that in the future their system will be connected to an array of cameras and various dates people who will allow the visually impaired to \Lead author Darby Losey – “In this case, neuroengineering has focused on decoding information from the brain. We are interested in how information can be encoded directly into the brain. This opens up great prospects for science. \
