"Pretty much every single monkey that had had implants put in their head suffered from debilitating health effects," said the PCRM's research advocacy director Jeremy Beckham. "They were, frankly, maiming and killing the animals."
Neuralink chips were implanted by drilling holes into the monkeys' skulls. One primate developed a bloody skin infection and had to be euthanized. Another was discovered missing fingers and toes, "possibly from self-mutilation or some other unspecified trauma," and had to be put down. A third began uncontrollably vomiting shortly after surgery, and days later "appeared to collapse from exhaustion/fatigue." An autopsy revealed the animal suffered from a brain hemorrhage.
The PCRM filed a complaint with the the US Department of Agriculture on Thursday, accusing UC Davis and Neuralink of nine violations of the Animal Welfare Act. "Many, if not all, of the monkeys experienced extreme suffering as a result of inadequate animal care and the highly invasive experimental head implants during the experiments, which were performed in pursuit of developing what Neuralink and Elon Musk have publicly described as a 'brain-machine interface,'" the group wrote in the complaint. [...]
Musk said in December that Neuralink hoped to start human testing this year.
