Elon Musk backed Neuralink hits big milestone, implanted brain chip completes 100 days

Neuralink, the brain implant company owned by Elon Musk, said that it had fixed an issue that saw its first patient's ability to move a computer cursor greatly reduced.

Musk's neurotechnology company in January installed a brain implant in Noland Arbaugh, the company's first human test subject, which the billionaire head of Tesla and X touted as a success.

Arbaugh was left paralyzed from the shoulders down by a diving accident eight years ago.

Shortly after the implant operation, he told of playing chess and the videogame "Civilization," as well as taking Japanese and French lessons by controlling a computer screen cursor with his brain.
