May 25 (Reuters) – Elon Musk’s brain-implant company Neuralink on Thursday said the U.S. Food and Drug Administration (FDA) had given the green light to its first-in-human clinical trial, a critical milestone after earlier struggles to gain approval.

The FDA nod “represents an important first step that will one day allow our technology to help many people,” Neuralink said in a tweet. It did not elaborate on the aims of the study, saying only that it was not recruiting yet and more details would be available soon.

Neuralink and the FDA did not immediately respond to Reuters requests for comment.

Musk envisions brain implants could cure a range of conditions including obesity, autism, depression and schizophrenia as well as enabling web browsing and telepathy. He made headlines late last year when he said he was so confident in the devices’ safety that he would be willing to implant them in his children.

On at least four occasions since 2019, Musk predicted Neuralink would begin human trials. But the company only sought FDA approval in early 2022 and the agency rejected the application, seven current and former employees told Reuters in March.
