Monkey brain chips research involving company Elon Musk co-founded drawing fire in California

Critics are raising concerns about medical research conducted at the University of California, Davis on live monkeys involving a company co-founded by Elon Musk called Neuralink, CBS San Francisco reports.

For several years, more than 20 monkeys at the UC Davis Primate Center were used in research to treat brain disorders. Neuralink's product is a computer interface that can be implanted in a brain to control motor function.

Pager, a 9-year-old macaque, had a Neuralink chip placed in each side of his brain. With it, Pager was able to play the video game Pong using only his brain waves.
