Brain Chip Helps Paralyzed Patient Move Robotic Arm With Thoughts

Two microchip sensors designed as a brain-machine interface implanted in the brain of a patient paralyzed from the neck down enabled the patient to use thoughts to control a robotic arm. After 13 weeks of training on using the brain-machine interface, the patient was able to use the arm to pick up and move various objects. The level of coordination with the robotic arm was equivalent to the function of a healthy person with a normal arm. The researchers investigating the technology concluded that with continued development of neuroprosthetic limbs, individuals with long-term paralysis could recover the . . .
