Elon Musk said a third person has received an implant from his brain-computer interface company Neuralink, one of many groups working to connect the nervous system to machines. “We’ve got ... three humans with Neuralinks and all are working well,” he said during a wide-ranging interview at a Las Vegas event streamed on his social media platform X.

Neuralink’s three implants are part of its ongoing Prime study, which is evaluating the safety of Neuralink’s brain device in individuals with quadriplegia. In September 2024, the company announced the approval of a second study known as Convoy, which will explore extending its brain device capabilities to control an assistive robotic arm.
