Back in the operating room, Michler prepares for the first incision--a small round hole through which the robotic arm will enter the left side of Oaks' chest. First goes the camera, then the miniature forceps and finally a tool called a cautery, which will be used to isolate the artery that the surgeons plan to attach to the heart to restore proper blood flow. As Michler steps back, the robot springs to life. Looking like the legs of an oversize metallic spider, the long black arms start to gyrate--both outside and deep inside the patient's body...

...helping fighter pilots fly jets with their minds. But the place where brains and computers are truly coming together is in the lab of Miguel Nicolelis, associate professor of neurobiology at the Duke University Medical Center in North Carolina. He has trained two owl monkeys to control a robotic arm via brain signals - giving glimpses of how the virtual and physical worlds may merge...
Working with colleagues at Duke, M.I.T.'s Laboratory for Human and Machine Haptics (also known as the Touch Lab) and the State University of New York Health Science Center, Nicolelis implanted electrodes into the sections of the monkeys' brains in which the planning and execution of arm movements takes place. When the brain instructs the body to make a motion, it fires off electric signals well before any action actually takes place; in other words, the body lags slightly behind the brain's intention to act. In effect, the brain warms up for an impending movement by directing specific clusters...
...they warmed up for various tasks, like reaching for food, and isolated the signals that preceded the movements. Then they routed the monkeys' brain signals through a computer. As a monkey started to grasp for food, the computer picked up the neural traffic and forwarded it to a robotic arm called the Phantom. When the monkey extended its arm, the Phantom, using the neural signals from the monkey, precisely mimicked the action. Nicolelis even transmitted the brain signals over the Internet to the Touch Lab in Cambridge, Massachusetts, so the monkey's neural commands operated another Phantom 965 km away...
