Brain implant allows paralysed woman to control a robot with her thoughts
The BrainGate implant can decode a patient's brain signals and instruct a robotic arm to reach and grasp objectsA woman who lost the use of her limbs after a devastating stroke nearly 15 years ago has taken a sip of coffee by guiding a robotic arm with her thoughts.The 58-year-old used a brain implant to control the robot and bring a flask of the coffee to her lips, the first time she had picked up anything since she was paralysed and left unable to speak by a catastrophic brain stem stroke.Doctors hailed the feat as the first demonstration of an implant that directly controls a reaching and gripping robotic arm by sensing and decoding the patient's brain signals.The work is part of a US clinical trial of an experimental implant called BrainGate that doctors see as a first step towards dev...
