NeuralinkNeuralink animal testing resulted in deaths of over 1,500 animals amid rushed protocols and USDA investigation

Between 2018 and 2022, approximately 1,500 animals including monkeys, pigs, and sheep died during Neuralink's brain implant research. Internal staff reported Elon Musk pressured teams to accelerate timelines, leading to botched surgeries - 25 pigs died from wrong-size implants. Monkeys suffered chronic infections, paralysis, and brain swelling. The USDA opened a probe in December 2022, and the DOT investigated improper handling of hazardous pathogens. The internal animal care committee was chaired by a Neuralink executive with financial stake in the company.
