The sensitivity of the nerve cells "was much higher than anybody had expected," he recalls, and it led him to speculate that brain waves and other background neural activity might likewise influence nerve cells.
Some scientists predict that the solution to these problems lies not in improving implantable electrodes, but in developing new systems to record brain waves from outside the skull's surface, the same pulses typically observed in an EEG.
