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.”

    You don’t even need to be inserting probes to be able to do that…

    OCZ had this ‘toy’ out in 2008.

    one of the reviews…

    Ultra-sensitive, excellent response time. Partial hands free gaming. Cool looking blue LED glow from interface box. This is the future of computer user interface. While designed primarily for FPS games, works exceptionally well with MMOs. Makes Crysis WARHEAD and FarCry 2 a joy to play. As a disabled person, this unit has allowed me to game with all the “normal” folks on the same level.

      ok but the real interesting stuff like reading hand writing from a paralyzed person imagining writing it and etc are all only for actual electrodes in brains.

      This thing seems to be a later iteration of the Atari Mindlink idea from the 1980s, which presented the illusion of controlling the game with just your thoughts/brain waves/whatever but which was actually just reading the neuromuscular voltage from your forehead (meaning you scrunch your forehead muscles around to control it).

      I still have this, but suspect it’s bricked after I’ve pressed the “do not press” button on the side. (i’m a filthy button pusher) If anybody has some firmware dumps or at least documentation, I’d appreciate it.

      Never managed to use the brainwaves, but it was sensitive to the facial muscle movement. Good enough to play pong.
