Elon Musk's Neuralink used monkeys to test its brain chip that can connect to a device. Musk said on X, formerly Twitter, that "no monkeys died as a result of Neuralink's chips." "First our early implants, to minimize risk to health monkeys, we chose terminal moneys (close to death already)," Musk wrote on September 10, misspelling monkeys. Other health effects included paralysis, seizures, loss of coordination and balance, and depression, PCRM wrote in the SEC letter. The average age of the dozen monkeys that died during Neuralink's research was 7.25 years, the group said.
