Paralyzed woman moves robotic arm using thought alone: Using the BrainGate neural interface system, a woman paralyzed by a brainstem stroke serves herself coffee for the first time in 15 years.
By implanting a 96-electrode sensor the size of a baby aspirin onto the surface of their brains, researchers have enabled two quadriplegic participants to use their thoughts alone to perform tasks with two types of robotic arms.
The BrainGate implant -- and the resulting Jedi mind tricks -- may be sort of anxiety-producing to some. But the smile on the face of the woman who hadn't been able to serve herself coffee in 15 years put a fine point on the progress the technology is affording.
