SAN FRANCISCO: Elon Musk on July 10 said his Neuralink startup is “moving on” to a second test patient as its tech for linking brains and computers improves. Musk and members of the Neuralink team fielded questions during an update streamed on X, formerly Twitter, discussing where it is on the path to making its brain implants commonplace. "We're only just moving now to our second Neuralink patient," Musk said.

"But we hope to have, if things go well, high single digits this year." Musk's neurotechnology company in January installed a brain implant in Noland Arbaugh, which the billionaire head of Tesla and X touted as a success. Arbaugh was left paralysed from the shoulders down by a diving accident eight years ago.



Since the implant operation, he has told of playing chess and the video game Civilization , as well as taking Japanese and French lessons by controlling a computer screen cursor with his brain. Musk and members of the Neuralink team detailed fixing an issue that saw Arbaugh's ability to move a computer cursor with his mind greatly reduced. Neuralink’s technology works through a device about the size of five stacked coins that is placed inside the human brain by a robotic surgeon.

Threads connecting the implant to Arbaugh's brain had “retracted”, becoming less effective at picking up signals. Threads will be implanted deeper in the brain and at varying depths, with ramped-up precision to maximise effectiveness, according to the Neuralink team. Musk promis.
