Research into new prostheses, neural networks connected to the person and managed by brain signals, never cease to amaze. It is possible that very soon the mechanical arms and legs with neurointerface, make life easier for many people who have lost limbs.

Also exercises with such devices are an effective way to rehabilitate patients paralyzed by illness or injury. After sending mental signals special manipulators, they again learn to control their own bodies.

Thanks to scientists at the University of Pittsburgh (University of Pittsburgh) paralyzed woman was able to help with mental commands to control a robotic arm. We have repeatedly written about similar work, but worth seeing the video to see how much progress has achieved a team led by Jennifer Kollindzher (Jennifer Collinger).

With the help of their patient who could not move more than a decade, was able to easily and accurately capture various objects and move them from place to place.

Scientists began their work about two years ago. At the same time became a permanent participant of tests 55-year-old Yang Scheuermann (Jan Scheuermann), lost mobility of the whole body from the neck down due to illness.
During the operation in the field of motor okra brain women were implanted with two small electrodes. After the analysis of the electrical activity of the brain, the computer chose 96 contact points with which learned to recognize what gesture mind wants to do the subject.

Then use the virtual simulator control system was calibrated and configured to Ian could start working with this manipulator.
The first controlled via the prosthesis could only do simple movements, for example, raise your hand up. Now the device can open and close your fingers, scoop or stack them neatly to take things with two fingers. The device implanted in the brain, allows you to control the hand that has ten degrees of freedom.

"It was a fantastic and thrilling action, and I'm glad that I got - says Scheuermann. - Research has enriched my life, gave me new friends and allowed to make their own contribution to the development of science."

In the future, the authors plan to work consider the possibility of sensory feedback due to a man could feel the touch of the manipulator to the subjects. Perhaps, for this they should refer to the experience of the creators of the highly sensitive artificial skin, which we recently wrote.
