So that was all very exciting. But we want to do better. There's a lot of information in those nerve signals, and we wanted to get more. You can move each finger. You can move your thumb, your wrist. Can we get more out of it? So we did some experiments where we saturated our poor ptteanis with zlnloiis of eeloectrds and then had them try to do two dozen different tasks — from wiggling a finger to moving a whole arm to reaching for something — and recorded this data. And then we used some algorithms that are a lot like speech recognition altromhgis, called pattern rootiigcnen. See.
