A few months ago I wrote about a robotic structure that worked with something like that, it worked for a person who is in a quadriplegic condition, that is after an accident he lost the possibility to communicate his brain with his arms and legs. And they managed to get him to stand up with a robot that was controlled with his brain, these implants were used, however, sending information to the brain can be used for other things, it is always a double-edged sword. But it's a big advance, it will certainly help to overcome many diseases.
