Elon Musk said during a live stream on X that the Neuralink device does not damage the brain.

The tiny wires in Neuralink’s brain chip implant used in the first participant in a trial run by Elon Musk’s company have become “more or less stable,” a company executive said Wednesday.

The company said in May that Noland Arbaugh, who was paralyzed from the shoulders down in a diving accident in 2016, has multiple tiny wires inside the brain.

“Once you’ve done brain surgery, it takes a while for the tissues to come in and anchor the threads in place, and once that happens,” said Neuralink executive Dongjin “DJ” Seo. Everything stabilizes,” said Neuralink executive Dongjin “DJ” Seo.

So far, Arbaugh, who is based in Arizona, has been the only patient to receive the implant, but Musk said he expects to participate in the high single digits this year.

Company executives said in a live stream on social media platform X that the company is now taking risk reduction measures such as skull sculpting and reducing blood carbon dioxide levels in patients to normal levels.

“In future implants, our plan is to deliberately shape the surface of the skull to reduce the gap under the implant…which will bring it closer to the brain and relieve some of the stress on the threads. Ga,” said Matthew McDougall, chief of neurosurgery at Neuralink.

Neuralink is testing its implant to give paralyzed patients the ability to use digital devices by thinking alone. The device uses tiny wires, thinner than a human hair, to receive signals from the brain and translate them into tasks like moving a mouse cursor on a computer screen.

Musk said during the live stream that the device does not damage the brain. The US Food and Drug Administration initially raised safety concerns when considering the device years ago, but finally gave the company the green light last year to begin human trials.

So far, the device has allowed Arbau to play video games, browse the Internet and move the cursor on his laptop, according to company blog posts and videos.

Neuralink is also working on a new device that it believes will require half the number of electrodes in the brain to make it more efficient and powerful, executives said.
