The chip from American billionaire Elon Musk’s Neuralink company has been implanted in the brain of a third patient, US media reports. Musk said the company plans to implant about 20 to 30 such chips this year.

“We now have three people who have had the Neuralink chip implanted, and they are all functioning well,” Musk said at an event in Las Vegas broadcast on the social network X.

Neuralink is one of a growing number of companies developing brain implants to help treat diseases like paralysis and amyotrophic lateral sclerosis. These are experimental procedures in which electrodes are inserted into brain tissue.

A year ago, Neuralink announced that it had implanted the first such device in a patient, Noland Arbo.
