An animal-rights group, Physicians Committee for Responsible Medicine, has submitted an official complaint with the US Department of Agriculture on Thursday where they have claimed that monkeys experiences "extreme suffering as a result to inadequate animal care and the highly invasive experimental head implants during the experiments," Business Insider reported.

PCRM also claimed that out of 23 monkeys owned by Neuralink, only seven survived the tests and were transferred to a Neuralink facility in 2020, while 15 died. However, Neuralink said only eight were euthanised
