Neuralink Corp. placed its first implantable brain-computer interface (BCI) into a patient over the weekend, founder Elon Musk announced on social media Monday.

“The first human received an implant from @Neuralink yesterday and is recovering well,” Musk posted on X, formerly Twitter. “Initial results show promising neuron spike detection,” the post read.

Musk’s company, which launched in 2016 and is based in Fremont, California, is planning on first using chips only in people who have lost the use of their limbs, Musk wrote.

“Imagine if Stephen Hawking could communicate faster than a speed typist or auctioneer. That is the goal,” another post stated.

The device will enable users to control their phone or computer just by thinking, according to Musk.

Neuralink has faced criticism in the past over its testing methods.

In 2022, Reuters reported the company was under federal investigation after complaints from staff that its animal testing was being rushed, causing “needless suffering and deaths.”

Despite the probe, the FDA permitted Neuralink to begin testing on humans in May 2023, the BBC reported.

That gave the go-ahead for a long-term study in which a robot can surgically place flexible threads onto a part of the brain that controls “movement intention,” the BBC reported citing Neuralink.
