Elon Musk's brain chip company, Neuralink, completed the first implant in a human.
The patient is recovering well and initial results "show promising neuron spike detection," Mr. Musk said in a Jan. 29 post on X, formerly known as Twitter.
In additional posts the same day, Mr. Musk introduced Telepathy, the first Neuralink product. It will let users control their phone or computer by thinking. The first users will be people who lost use of their limbs, the posts said.
The first human Neuralink patient has been a long time coming. Recruitment for human trials began in September, and the company was seeking patiennts with quadriplegia due to cervical spinal cord injury or amyotrophic lateral sclerosis.
The company recieved FDA approval for human trials in May, but advocates have warned against the device.
Another competitor in the space, Synchron, has been studying its own brain implant in humans. So far those trials found the device was effective for long-term use in four patients with severe paralysis.
