With the help of brain-computer interfaces, patients have been able to perform basic mind-controlled tasks in the lab. Current designs for monitoring the electrical firings of single neurons consist of arrays of electrodes implanted in the brain, wired to a pedestal that sticks out of the skull. During use, the pedestal is connected to a computer that decodes recorded brain signals to move a cursor on the screen, or even a robotic arm.
