Staff observed that though she was uncomfortable, picking and pulling at her implant until it bled, she would often lie at the foot of her cage and spend time holding hands with her roommate.

That is just incredibly sad. Those poor animals suffering for that megalomaniacs ego.

Musk first acknowledged the deaths of the macaques on September 10 in a reply to a user on his social networking app X (formerly Twitter). He denied that any of the deaths were “a result of a Neuralink implant” and said the researchers had taken care to select subjects who were already “close to death.” Relatedly, in a presentation last fall Musk claimed that Neuralink’s animal testing was never “exploratory,” but was instead conducted to confirm fully formed scientific hypotheses. “We are extremely careful,” he said.

Public records reviewed by WIRED, and interviews conducted with a former Neuralink employee and a current researcher at the University of California, Davis primate center, paint a wholly different picture of Neuralink’s animal research. The documents include veterinary records, first made public last year, that contain gruesome portrayals of suffering reportedly endured by as many as a dozen of Neuralink’s primate subjects, all of whom needed to be euthanized. These records could serve as the basis for any potential SEC probe into Musk’s comments about Neuralink, which has faced multiple federal investigations as the company moves toward its goal of releasing the first commercially available brain-computer interface for humans.

The letters to the SEC come from the Physicians Committee for Responsible Medicine, a nonprofit striving to abolish live animal testing. The group claims that Musk’s comments about the primate deaths were misleading, that he knew them “to be false,” and that investors deserve to hear the truth about the safety, “and thus the marketability,” of Neuralink’s speculative product.

“They are claiming they are going to put a safe device on the market, and that’s why you should invest,” Ryan Merkley, who leads the Physicians Committee’s research into animal-testing alternatives, tells WIRED. “And we see his lie as a way to whitewash what happened in these exploratory studies.”

For example, in an experimental surgery that took place in December 2019, performed to determine the “survivability” of an implant, an internal part of the device “broke off” while being implanted. Overnight, researchers observed the monkey, identified only as “Animal 20” by UC Davis, scratching at the surgical site, which emitted a bloody discharge, and yanking on a connector that eventually dislodged part of the device. A surgery to repair the issue was carried out the following day, yet fungal and bacterial infections took root. Vet records note that neither infection was likely to be cleared, in part because the implant was covering the infected area. The monkey was euthanized on January 6, 2020.

Additional veterinary reports show the condition of a female monkey called “Animal 15” during the months leading up to her death in March 2019. Days after her implant surgery, she began to press her head against the floor for no apparent reason; a symptom of pain or infection, the records say. Staff observed that though she was uncomfortable, picking and pulling at her implant until it bled, she would often lie at the foot of her cage and spend time holding hands with her roommate.

Animal 15 began to lose coordination, and staff observed that she would shake uncontrollably when she saw lab workers. Her condition deteriorated for months until the staff finally euthanized her. A necropsy report indicates that she had bleeding in her brain and that the Neuralink implants left parts of her cerebral cortex “focally tattered.”

Yet another monkey, Animal 22, was euthanized in March 2020 after his cranial implant became loose. A necropsy report revealed that two of the screws securing the implant to the skull loosened to the extent that they “could easily be lifted out.” The necropsy for Animal 22 clearly states that “the failure of this implant can be considered purely mechanical and not exacerbated by infection.” If true, this would appear to directly contradict Musk’s statement that no monkeys died as a result of Neuralink’s chips.

what really confuses me is how the FDA approves this without a few more years of animal testing and protocol refinement.

These are conscious beings. Imagine being trapped in a lab where the next time you wake up you might not have full motor function?

At this point, who trusts musk enough to let him have control of their brain?

This is nightmare fuel. Why is this allowed ?

He is so fucked over this, animal experimentation is incredibly tightly regulated. primates even more so.

This is how we create Mojo Jojo on accident

Unregulated God complex, and sickening leaves of wealth surely that can't become harmful in any way.

Unfortunately as far as I know it is pretty standard for monkeys used to test brain interfaces to eventually get infected because of it and have to be put down.

I'm not sure whether the same problems are as common in humans; humans are much less likely to e.g. yank on the implant, especially if the reason they have an implant is to work around some kind of paralysis. And humans are allowed drugs that animals are not.

This is messed up. It's like something out of a sci-fi horror film. Have to hope no one is stupid enough to put a computer chip in their brains.

The difference in comments here is between those who show compassion for the suffering of animals - and, by extension, humans - versus those who do not and view this as merely political theater in their unlimited support of Elon.

“Science cannot move forward without heaps.”

It's like the start of a terrifying science fiction movie where things are about to go horribly, horribly wrong.
