NEW YORK (AP) -- Researchers report that a paralyzed Massachusetts woman used her brain waves to direct a robotic arm to pick up a bottle of coffee and bring it to her lips for a few sips.

The woman was one of two quadriplegics testing the new technology in a study reported by scientists from Brown University, Harvard and elsewhere. Implanted in her brain was a chip about the size of a baby aspirin. It sent signals from her brain to a computer, which sent commands to the robotic arm.

The researchers said they hope that someday in the future this kind of technology will enable paralyzed people to use their own arms again. Other similar experiments have been reported. This latest effort is published online Wednesday in the journal Nature.
