Robotic Arm Controlled By Monkey Thoughts

mallumax writes "The BBC reports that Pittsburgh University scientists have succeeded in creating a robotic arm, controlled by probes inserted into the brain of monkeys. The probes interpret signals from individual nerve cells in the motor cortex. Monkeys were able to grasp and hold food with the robotic arm. Since the number of nerve signals for even small movements is huge the scientists used an averaging algorithm to obtain the movement signals."
