Neuralink has shared a video of its brain-computer interface in action inside a human patient. The patient, a 29-year-old man named Nolan Arbaugh who is paralyzed from the neck down, is able to control a cursor on a screen using Neuralink's device. He is able to play games online for about eight hours before the implant needs to recharge. Arbaugh reports that his experience with the implant has so far been positive, despite some initial issues. The video is available in the article.
