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.”

Not the person you were responding too but I'd love to learn more about these toys/tech. Are there some key words that would help me search? I'm having some trouble sifting through the search results.

Neural Impulse Actuator or brain-computer interface.

They’re usually marketed as “mind control” toys and are operated with a headset that sends a signal to hidden fans that control whatever object it is you’re supposed to be manipulating. Mattel came out with one called Mindflex that’s pretty complicated looking and has a matching price tag, there are some cheaper Star Wars branded ones too. Not sure what brand I tried as it was over a decade ago, but it was a two player game where you tried to move the ball towards the other player along a track.

I think the most famous one was the star wars jedi force trainer? Some people say it's fake but.. it's like a headset you put on that they claim reads your brain waves and it controls a little fan that switches on and off to make a ball in a tube float
