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.”

      Agreed. I was flippant after reading the headline, since I don’t like Musk, but once I read the story I was like "oh yeah this tech does have big potential for the differently abled. "

      A quadriplegic being able to control a cursor on a screen with the implant for 100 days seems like a legit first attempt.

      Could be great for the accessibility movement in the long run. But I could be naive or too optimistic.

        There are some politically correct terms that are not well liked by the people they describe:

        • Differently abled
        • Houseless
        • Latinx

        Why, when we already have non-surgical solutions that allow the same thing but don’t come with the risk of killing you?

          I agree with not liking ‘differently-abled’ as a term. To me it reads along the same lines as ‘disabled people are built different’. Pretty awkward.

          Not that I have a horse in this race. Or a neuralink, as the case may be.

            Yeah I feel like it’s an attempt to resolve the Deaf stance that deafness isn’t a disability. The general stance of the Deaf community is closer to that of the queer community than that of say the paraplegic community. It sees deafness as a disability constructed by a society unwilling to communicate visually and to teach signed languages to all people able to use them.

            Mind you we’re the contentious portion of the disabled world. The Deaf are as bad as lesbians I tell ya.

            But on point, “differently abled” feels like it washes away the struggle. I am disabled. I’m disabled by a society that taught my great grandparents, my grandparents, and my parents not to teach their hard of hearing children sign language because otherwise we won’t use English. I’m disabled by a society that doesn’t include visual signals in emergency sounds even when it’s easy to do. I’m disabled by a society where people, including cops, will speak to the back of my head and not even consider that I didn’t respond because I didn’t hear. And I’m disabled by the assumption my life has to be worse for having less sound as though I’m not extremely literate and completely capable of using a signed language. I’m not “differently abled” I’m completely able in most ways everyone else is, and people who can’t learn to communicate visually are just as disabled as people who can’t learn to communicate audibly.

              I know this is a point of some contention among the deaf community, but how do you feel about the development of a “standard” international sign? Personally, and I’m speaking as a fully hearing person, I think a basic international sign should be developed and taught to everyone. Not only to facilitate communication with the hard of hearing, but also in loud environments and with those who don’t share a spoken language.

              It’s my understanding that a large portion of the deaf community is hostile to the idea of a universal sign from a cultural perspective, since each regional sign has cultural content. However I think it’s a potential solution for numerous issues, with more pros than cons.

                You misunderstand language itself, not just sign language, if you think a universal language is possible or even a good thing

                  It would certainly be limited and rudimentary; I wouldn’t suggest a solution exists capable of any broad nuance. But gesture is a unique variety of communication, in that it can convey “innate” meaning in ways verbal language simply cannot, except in the case of onomatopoeia. Pointing is nearly universal, smiling is nearly universal, beckoning is nearly universal. Gesture is a spatial form of communication, centered around our primary means of material interaction with the world.

                  Grammar and syntax aside, I’d argue that it would be possible to assemble a vocabulary of universal concepts (eat, drink, sleep, travel, me, you, communicate, cooperate, come here, go away, etc). Certainly not a language for extended detailed conversation, but a codification and extension of gestures which are already nearly universal by virtue of their innate implications alone. Enough to communicate that you’re hungry, but not enough to send for takeout.

                  A universal language, at the level of any other sophisticated language, is obviously impossible. A formal codification of simple gestures to communicate at the most basic human concepts is much more doable.

                    I can tell you only speak one language, or maybe another Latin based language in addition to English. If you’d learned something like Mandarin, you’d understand how complex, regional, and historical language is. It’s based on layers and shifts constantly. Sometimes, that’s specifically because people don’t want to be understood by everyone.

                    I really recommend reading academic books about this topic if you are curious. My favorite is Neurolinguistics and Linguistic Aphasiology, by David Caplan. You may also enjoy Chomsky’s works because he talks about commonalities in language or universal language.

                    There’s no need to formally codify those hand gestures, because we innately already understand and make them. Making eating motions (which may look different depending on regional utensils) is pretty universal right? But it looks different in different places.

                The deaf argument is that there’s no need for assistance of assistive tools. An all deaf town would experience no undue hardships unlike an all blind town.

                I’m personally on the fence about it, but trust me when I write that we’ve seen whatever your gut instinct on this is before. Your gut take is just a hearing person speaking against Deaf theory written by Deaf people and the people far more involved in it are probably not going to see it because the Deaf don’t deal with the hearing as much as other disabled groups do, for obvious reasons.

                  How do people who have gained hearing feel about it? It seems like hearing would be important for a number of things besides communication, but maybe modern life doesn’t require much?

                    There’s a variety of opinions. Born deaf often don’t like it. The later deafened you are the more you tend to want hearing back.

                    It’s not even about the communication per se, it’s also about the physical act of hearing which can be uncomfortable

          Why

          Why not? Nothing wrong with research and development as long as everyone participating in the test is an informed, consenting adult IMO. The advancements could make current accessibility tech even better. For one reason or another, a quadriplegic person decided they were willing to take the risk, so maybe they consider current accessibility tech for quadriplegics to be insufficient and wanted to try for something better?

          I get that there are better choices now, but let’s not pretend like a straw you blow into is the technological stopping point for limb-free computer control (sorry if that’s not actually the best option, it’s just the one I’m familiar with). There are plenty of things to trash talk Neuralink about without pretending this technology (or it’s future form) is meritless.

            I feel like I’m going nuts, is eye controlled adaptive tech really that obscure? We’re not talking about maybe letting people walk again or giving them otherwise unattainable control over a computer, we’re talking about a different mouse input. The risks should be proportional to the gains.

              Can you take a moment and imagine some possibilities of taking input directly from someone’s mind and applying it without needing to use your body? I know moving a mouse doesn’t seem impressive, but it demonstrates success at a technological concept that still seems impossible. I can’t speak for the ethics because I don’t know how voluntary the subjects are for the research, but this is very exciting for me, because it will inevitably become more sophisticated.

                    I don’t accept that disabled people must be sacrificed at the altar of Progress, and I think the entire process for how they recruit patients and explain the capabilities and risks of the implant deserves extreme scrutiny. There’s a reason doctors have to get hours of education in ethics to be considered competent, it’s a lot more complicated than “just do whatever if it can technically work for a bit.”

            Is it worth risking dying to be able to move a mouse slightly faster than you can move your eyes and blink? If your answer to that is yes that’s your body, but I think it’s important to contextualize that the options here aren’t brain implant or nothing.

        When a company stops supporting devices like this, the devices and their documentation and code should be required to enter the public domain. It should not be allowed for assistive devices to become e-waste stuck in a patient’s body.
