First human brain implant malfunctioned, Neuralink says (thehill.com)

The first Neuralink implant in a human malfunctioned after several threads recording neural activity retracted from the brain, the Elon Musk-owned startup revealed Wednesday.

The threads retracted in the weeks following the surgery in late January that placed the Neuralink hardware in 29-year-old Noland Arbaugh’s brain, the company said in a blog post.

This reduced the number of effective electrodes and the ability of Arbaugh, a quadriplegic, to control a computer cursor with his brain.

“In response to this change, we modified the recording algorithm to be more sensitive to neural population signals, improved the techniques to translate these signals into cursor movements, and enhanced the user interface,” Neuralink said in the blog post.

The company said the adjustments resulted in a “rapid and sustained improvement” in bits-per-second, a measure of speed and accuracy of cursor control, surpassing Arbaugh’s initial performance.

While the problem doesn’t appear to pose a risk to Arbaugh’s safety, Neuralink reportedly floated the idea of removing his implant, according to The Wall Street Journal.

The company has also told the Food and Drug Administration that it believes it has a solution for the issue that occurred with Arbaugh’s implant, the Journal reported.

The implant was placed just more than 100 days ago. In the blog post, the company touted Arbaugh’s ability to play online computer games, browse the internet, livestream and use other applications “all by controlling a cursor with his mind.”

Because they kinda suck in a way wheelchairs don’t. Wheelchairs grant an alternative to ambulation. Cochlear implants give a new sense, one that those born without it literally don’t have the brain buildup to deal with. Like, look into those who got it and don’t use it. And often they’re forced on children by parents who will never learn sign language. I’m on board with children getting CIs as a teenager if a mental health professional with expertise in the deaf signs off that they weren’t unduly coerced, but it’s a major medical decision often forced or coerced on infants and young children by hearing parents and a hearing society to serve the interests of the hearing rather than the deaf child.

Fucking hell, hearing aids are uncomfortable. And not just because it’s something inside your ears. Like, it’s not the same as natural hearing (my loss is degenerative, I’ve had both). The sound filtration is worse and it overstimulates the brain. But hearing people get angry when you turn your ears off because you need a break because to many hearing people the point is to make you not deaf/hard of hearing. But the fact is we always are, it’s just that sometimes we’re using an assistive device that is often uncomfortable or outright painful.

Cochlear implants might be better seen as a lesbian having a platonic husband instead of a romantic wife. It’s uncomfortable assimilation and a worse solution in the absence of social pressure, and it gives the pressure ammunition. Absent the social pressures, it’s your choice. And to be upfront, I expect to get them once my hearing reaches the point they’re better than hearing aids. And also if I was a native signer they would have to earn a place in my skull and I’m angry that I’m not a native signer. As I implied, my hearing loss is genetic, and it fits pretty well to what your middle school taught you about a mono-allele dominant trait.

Wheelchairs are often seen as liberating to their users. Hearing aids and cochlear implants are often seen as burdens to their users. Nobody has to punish their child or nag their spouse into using their wheelchair, but for hearing devices, it’s common, it’s expected, it’s something you’re warned about beforehand. Please be understanding of the Deaf, we may not always be the nicest or easiest to understand, but nobody understands deafness better than us.

Actually in the wheelchair community, there can indeed be pressure to use the least assistive wheelchair possible. Chairs aren't 100% seen as liberating and there's a lot of nuance into why people pick certain chairs beyond finances. My aunt repeatedly fell out of her chair because she insisted on one made for a lower back injury than she has. She kept it for status, because she looks more able without the sides.

I guess 'differently abled,' just comes across as ableism to me. Not using visible signs of a disability, like a chair or hearing aids, can be internalized ableism. Some of the worst verbalized ableism I've heard has come from disabled communities. It's a very complicated topic, not least because disability is used to harm disabled people and take away their agency. And for many, there is a lot of grief with using assisitive devices.

That being said, I don't think people should be forced to change or to use devices they dislike. My aunt still uses her chair, it's not like we're going to drag her into another one or whatever. I just wanted to point out the internalized ableism that could be contributing to this attitude and word change.

It wasn't so long ago that the Civil rights Era stopped disabled people from being chained in attics and lobotomized and hid away. It's entirely reasonable to fear that association.
