Wow, very impressive progress!
"the study, which appears in the journal Nature, scientists at the University of Washington in Seattle implanted ultra thin electrodes into the brains of macaques which had been trained to play a game that involved rotating their wrists to the left and right. While the monkeys played, the electrodes picked up electrical signals in their brains that made them tense different muscles.

The scientists then injected the monkeys with a chemical that temporarily paralysed their arms. This time, signals from nerves in their brains were fed into a computer, cleaned up and magnified, and sent down a wire to muscles in the monkeys' wrists.

When the monkeys tried to play the game again, they were unable to at first, but soon learned to control their wrist movements using the brain implant. when he found something worked, he quickly repeated it and adopted the strategy"

very nice!
