In the past year, similar stories have included a quadriplegic man in Pennsylvania who made a robotic arm give a high-five and stroke his girlfriend's hand, and a partially paralyzed man who remotely controlled a small robot that scooted around in a Swiss lab.
It's startling stuff. But will the experimental brain-controlled technology ever help paralyzed people in everyday life?
Experts in the technology and in rehabilitation medicine say they are optimistic that it will, once technology improves and the cost comes down.
The latest report, which was published online Wednesday in the journal Nature, comes from scientists at Brown University, the Providence VA Medical Center in Rhode Island, Harvard Medical School and elsewhere.
