The first Neuralink implant in a human malfunctioned after several threads recording neural activity retracted from the brain, the Elon Musk-owned startup revealed Wednesday.

The threads retracted in the weeks following the surgery in late January that placed the Neuralink hardware in 29-year-old Noland Arbaugh’s brain, the company said in a blog post.

This reduced the number of effective electrodes and the ability of Arbaugh, a quadriplegic, to control a computer cursor with his brain.

“In response to this change, we modified the recording algorithm to be more sensitive to neural population signals, improved the techniques to translate these signals into cursor movements, and enhanced the user interface,” Neuralink said in the blog post.

The company said the adjustments resulted in a “rapid and sustained improvement” in bits-per-second, a measure of speed and accuracy of cursor control, surpassing Arbaugh’s initial performance.

While the problem doesn’t appear to pose a risk to Arbaugh’s safety, Neuralink reportedly floated the idea of removing his implant, according to The Wall Street Journal.

The company has also told the Food and Drug Administration that it believes it has a solution for the issue that occurred with Arbaugh’s implant, the Journal reported.

The implant was placed just more than 100 days ago. In the blog post, the company touted Arbaugh’s ability to play online computer games, browse the internet, livestream and use other applications “all by controlling a cursor with his mind.”

    Had a class with some ABA techs who gave a presentation about Autism Speaks for their final project - they had no idea that criticism of AS/their entire field existed.

      oh, ABA, you mean the “therapy” that for some reason causes a suicide rate of over 70%?

      tho an “ABA tech” is cheaper than an actual medical professional since they just need a few weeks of training instead of several years

        It’s hard to get away with “your presentation and profession is shit and you didn’t bother looking into any information other than your first google search” as a peer unfortunately. I did manage some gentle questions about AS’s one autistic board member’s exit….

        It is fascinating that “behavioral health” seems to be just torturing/drugging kids until they get “better”/learn to comply. I didn’t get ABA, but very similar treatment.

          it’s not really that fascinating, of course the cheap and easy answer is a derivative of “beat it until it behaves”, a large part of the states still have the paddles in school

            In the states? At least in mine, parents have to give permission for the school to paddle. Most districts don’t want the liability or the paperwork. At least in public ed.

              do I have to go into the levels of fucked your comment still leave the US at? most of the first world has not just stopped school corporal punishment, no it’s just straight up illegal to beat your child as punishment.

              If a parent here gave consent to corporal punishment, with a paddle no less, they would soon see their child in foster care and themselves in front of a judge.
