Brain-machine interfaces for cyborgs

DVICE: Brain-machine interface today, cyborgs tomorrow: "While prosthetic limbs are common, real cyborgs remain in the realm of science fiction. That's because the trickiest part — creating a reliable brain-machine interface (BMI) — is a tough job, since we don't fully understand how the brain works. One man on the case, however, is Miguel Nicolelis, who's developed a chip that lets human brains communicate directly with robotic limbs, whether they're in the same room or on the other side of the world."
