The tournament, which will be held in his native Brazil, is less than 16 months away. If all goes according to plan, during the opening ceremony, a young paralyzed person will step onto the field in a robotic exoskeleton operated by electrodes implanted in his or her brain, walk about 20 steps, and kick a soccer ball.
This may sound incredible, but in recent years, research on using signals from the brain to operate machines has taken great strides. Scientists have developed brain-machine interfaces that allow paralyzed humans to move a computer cursor or even use a robotic arm to pick up a piece of chocolate or touch a loved one for the first time in years. Nicolelis has set his sights even higher: He wants to get paralyzed people up and walking around. If he succeeds it could be a tremendous advance. Right now he’s still developing this technology in monkeys. There’s a long way to go.
