Elon Musk's Neuralink brain chip tests kills 15 monkeys out of 23

The San Francisco company Neuralink, owned by Elon Musk, has been working on a chip that can be implanted in the human brain and linked to a computer. This chip will monitor and potentially stimulate brain activity.

For this, the bio tech company has been carrying several tests on monkeys. However, Musk's Neuralink has been accused of subjecting its monkeys to illegal mistreatment and extreme suffering during chip implants tests.

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.
