I'm not a TV addict, actualy i must spend an hour per month watching it, but last night, i saw a news report on the first neuro chips.
First, they made a cranial chip that could interpret simple commands, like a tv remote control activated by thoughts.
But then they talked about a chip that could give directional orders on a human being. Technicaly, a guy has a remote control (like for miniature cars) and just pushes the joysticks right and left, and the implanted human goes right and left.
I could not find datas on the internet, but probably there is something on it.
