Elon Musk’s computer-brain interface startup Neuralink said this week that the first human brain implant encountered some technical problems in the weeks following its implantation, which resulted in some loss of connectivity.
The California-based business revealed in a blog post on Wednesday that an unknown quantity of incredibly thin threads that assist quadriplegic Nolan Arbaugh in controlling a computer cursor with his brain unexpectedly “retracted” from his brain.
According to the business, engineers increased the implant’s sensitivity to neurological signals and changed how these signals translate into cursor movements to make up for this loss. It claimed that these adjustments eventually led to “a rapid and sustained improvement… that has now superseded Noland’s initial performance.”

The FDA, which authorized Neuralink’s first human clinical trial a year ago this month, has been in communication with the firm and has been informed that it thinks it knows how to resolve the implant’s issues, according to the Journal as well.
Arbaugh, who was paralyzed in 2016, showed off his ability to autonomously activate different computer programs with his brain in a livestream video on Saturday. He had previously held a stylus in his mouth. According to him, the program’s accuracy increases with increased use.
He demonstrated his ability to play video games, access online literature, and use a language study tool. “Before I was having to do this in the most suboptimal way I think in the world, so it’s already changed my life as far as that goes, and it’s only going to get better,” he said.
According to Neuralink, it intends to keep enhancing its text entry and cursor control features. It also hopes to ultimately take control of wheelchairs, robotic arms, and other devices used by quadriplegics.
