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.”

    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.

        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.

                I am familiar with the regionality of language. I don’t understand your point, you’re simultaneously saying that you can’t have universal understanding, but we have gestures we instantly understand instantly so there’s no need to codify them, but they look different.

                I think you’re wildly overestimating the scope of my proposal.

                  You are simply moving goalposts. My point is that I disagree with your idea of making sign language universal or formally making even a rudimentary universal sign language. I think that would be impossible if you understand language itself. I gave you resources so you could educate yourself about why.

                  Yes, the sign for eating would look different in China vs Ethiopia vs the US. So what sign are you going to have it be to imitate eating in your formal language? Do you see how this can perpetuate colonization?

                    My goalposts are in precisely the place they started: a collection of basic international gestures to facilitate the most basic communication. Where are you jumping to colonization? Where did I say that my cultural group gets to decide what the signs are? You’re, again, wildly overestimating the scope of my proposal and jumping to ridiculous, unsubstantiated conclusions.

                    You get a group of signers from around the world to develop an international pidgin (like they already do informally at international gatherings) and come to consensus based on commonality. When the majority agree on a sign, use it. Where there’s little agreement, choose a new sign. No finger spelling, no complex abstract concepts, just a formalization of gestures most people could probably figure out anyway. I fail to see how that perpetuates colonization unless that’s what you’re setting out to do with your methodology.

          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

                  Yeah, you can build it up, but it’s unpleasant and slow and idk if it can get all the way.

                  Basically (from what I remember/understand) your body loves “use it or lose it” on anything resource intensive, and nothing uses resources like brain. So if you aren’t getting sound you let other stuff butt in on that area and you never build up auditory processing. Add in the fact that CIs don’t work the same as biological cochleas (seriously there’s videos with sound replicating various CIs) and you basically have to relearn how to hear.

                  Another connection is actually autistic people with issues with verbal communication often don’t have those issues with sign language. It’s processed differently but not in a way that makes it super hard to learn, it’s honestly easier to pick up than most languages.
