The first invasive brain chip that Neuralink embedded into a human brain has malfunctioned, with neuron-surveilling threads appearing to have become dislodged from the participant's brain, the company revealed in a blog post Wednesday.

It's unclear what caused the threads to become "retracted" from the brain, how many have retracted, or if the displaced threads pose a safety risk. Neuralink, the brain-computer interface startup run by controversial billionaire Elon Musk, did not immediately respond to a request for comment from Ars. The company said in its blog post that the problem began in late February, but it has since been able to compensate for the lost data to some extent by modifying its algorithm.

Well, that'll happen if you don't take your Neuropozyne. Their test subject should have budgeted for that before getting augmented.

No one could have predicted this totally predictable situation.

Well... that's probably the most expected thing to ever be expected. It was never a matter of 'if', it was a matter of when.

Because that's what people are worried about: THE LOST DATA.

Can you imagine the marketing value?

The blog is obviously targeted towards advertisers. The future looks amazing and full of possibilities. Just think about how your 8 hours of sleep alone could be turned into product placement opportunities for nestle.

I can't believe anyone willingly got this after the monkey testing thing. They have to be taking advantage of people not fit to make decisions for themselves.

The patient became quadriplegia in a car accident, I wouldn't call it unfit for decisions but definitely someone desperate to find a sense of normalcy.

I thought the goal was to reconnect the brain to the spinal cord though.

But dude is still stuck in a wheelchair, and so far it's basically been just a fancy experimental mouse cursor? Installed in his brain? And already failing?.....

I don't really keep up with Elon moon shits, but I think the idea is to substitute the brains neurological commands. Research is still on the "read" stage, like knowing what information the brain is requesting. Eventually neurolink will also need to discover how to relay those signals back to the nervous system in a way it understands, engaging muscles and such, effectively rebuilding the bridge that was damaged. Or robot legs or whatever, but the key is first getting the information into a format they can act on. But I'm not smart, this is just how I understood it.

And they already killed how many monkeys testing this stuff? Last I heard was that they tested 15 monkeys or so, and 13 of them ended up dying or having to be euthanized after only a few months.

They already admitted they had problems with their brain electrodes corroding after a few months or so...

I like to keep my noodle intact thank you very much. Even if I was a vegetable, I wouldn't want a chip in my head that's known to have corroding wires.

Just another rapid disassembly, nothing to see here..

Honestly surprised he didn't just run into a wall

This is the best summary I could come up with:


Neuralink, the brain-computer interface startup run by controversial billionaire Elon Musk, did not immediately respond to a request for comment from Ars.

The goal is for the threads to be placed near neurons of interest so that signals detected by the electrodes can be recorded and decoded into intended actions, such as moving a cursor on a computer screen.

On January 28, the company announced that it has surgically implanted its brain-computer interface into its first clinical trial participant, 29-year-old Noland Arbaugh, who developed quadriplegia after a 2016 diving accident.

It remains unclear why the threads moved from their placement, but one hypothesis that sources told the Journal is that there was air trapped inside Arbaugh's skull after the surgery, a condition called pneumocephalus.

However, the company reported that the retraction of the threads lowered his bits-per-second (BPS) rate, which is used to measure how quickly and accurately a patient with an implant can control a computer cursor.

The Journal reported that the company has told the Food and Drug Administration—which regulates clinical trials and granted approval for Neuralink to test its device in humans—that it believes it has fixes for the problem.
