More medical prosthesis news. Roland Piquepaille writes, "You probably remember the story which surfaced in May 2005 about monkeys using robotic arms as their own. Now, according to the ANBA press agency, Miguel Nicolelis, the professor of neurology at Duke University who was behind the experiments with the monkeys, wants to go further. He plans to install chips in humans' brains in order to control prosthetic arms. Of course, there is still some work to do with animals before this kind of surgery can be practiced on humans. But the first surgery in the world to implant a neuro-prosthesis inside a human being is expected to be performed in a Brazilian hospital by 2008."
