"Paralyzed, Moving a Robot With Their Minds"
"'Two people who are virtually paralyzed from the neck down have learned to manipulate a robotic arm with just their thoughts, using it to reach out and grab objects. One of them, a woman, was able to retrieve a bottle containing coffee and drink it from a straw — the first time she had served herself since her stroke 15 years earlier, scientists reported on Wednesday.
She had a smile on her face that I and the research team will never forget,” said Dr. Leigh R. Hochberg of the Department of Veterans Affairs, an author of a study reporting the achievement.
The report, released online by the journal Nature, is the first published demonstration that humans with severe brain injuries can effectively control a prosthetic arm, using tiny brain implants that transmit neural signals to a computer.
Scientists have predicted for years that this brain-computer connection would one day allow people with injuries to the brain and spinal cord to live more independent lives. Previously, researchers had shown that humans could learn to move a computer cursor with their thoughts, and that monkeys could manipulate a robotic arm..."
