US Regulators Rejected Neuralink's Bid To Test Brain Chips In Humans, Citing Safety Risks (reuters.com) 68

According to Reuters, Elon Musk's medical device company, Neuralink, was denied permission last year to begin human trials of a revolutionary brain implant to treat intractable conditions such as paralysis and blindness. The U.S. Food and Drug Administration (FDA) outlined dozens of issues the company must address before human testing can begin, according to seven current and former employees. From the report: The agency's major safety concerns involved the device's lithium battery; the potential for the implant's tiny wires to migrate to other areas of the brain; and questions over whether and how the device can be removed without damaging brain tissue, the employees said. A year after the rejection, Neuralink is still working through the agency's concerns. Three staffers said they were skeptical the company could quickly resolve the issues -- despite Musk's latest prediction at a Nov. 30 presentation that the company would secure FDA human-trial approval this spring.

Neuralink has not disclosed details of its trial application, the FDA's rejection or the extent of the agency's concerns. As a private company, it is not required to disclose such regulatory interactions to investors. During the hours-long November presentation, Musk said the company had submitted "most of our paperwork" to the agency, without specifying any formal application, and Neuralink officials acknowledged the FDA had asked safety questions in what they characterized as an ongoing conversation. Such FDA rejections do not mean a company will ultimately fail to gain the agency's human-testing approval. But the agency's pushback signals substantial concerns, according to more than a dozen experts in FDA device-approval processes.

The rejection also raises the stakes and the difficulty of the company's subsequent requests for trial approval, the experts said. The FDA says it has approved about two-thirds of all human-trial applications for devices on the first attempt over the past three years. That total rose to 85% of all requests after a second review. But firms often give up after three attempts to resolve FDA concerns rather than invest more time and money in expensive research, several of the experts said. Companies that do secure human-testing approval typically conduct at least two rounds of trials before applying for FDA approval to commercially market a device.

    It's that he had the temerity to ask after what we already know happened to those monkeys. It's at least a good sign that there is some functioning regulation left for our medical industry
  • Oh, so 2/3 of the applications are approved on the first try? Are these for brain implants? Do they involve novel surgical techniques? Probably not.
    Most firms give up after 3 tries? Are they firms with a single product and a specific goal of bringing that product to market. Do they have essentially unlimited funding from the wealthiest person in the world? No? So that's not really relevant either, is it? This is just more FUD from the usual suspects.

  • I understand that there are some legitimate medical conditions for which a chip implanted in the brain might have some therapeutic benefits (epilepsy and similar mental illnesses). However, it also opens up the possibility for ethical dilemmas, should this technology be used for things like behavior modification.

    Suppose it could help you lose weight or quit smoking? That's not so bad.

      This technology is closer to the level of "sepsis" and "chew your own lips off" than "thought control", and anyone who performs the surgery is closer to "malpractice" than anything else.
    • Cure your kid of ADHD? We’re getting into a gray area now. Turn gay people straight/trans people cisgender? Now we're firmly in ethical dilemma land.

      They would never be used for anything so morally grey as that. I mean, where even would the profit be in that? No, they just want to pipe commercials directly into your brain so you can’t ignore them. Forever.

      • I think the profit from that would be turning people into perfect worker bees. Imagine if you was an employer could implant a chip into somebody's head that made them perfectly loyal to your company and willing to accept substandard living conditions and long work hours in exchange for low pay all without ever discussing unions or turning to a violent revolution.

        That said this company is nowhere near ready to do anything. Besides mangling a few poor monkeys they haven't accomplished anything whatsoever

          Why would they need to imagine it when they already have plenty of people like you who are living proof that none of those things are mutually exclusive?

          That was basically the plot of Star Trek Voyager's Workforce [imdb.com] episode, except accomplished in the story by means of "brainwashing". More recently, the Halo TV series on Paramount+ depicted the SPARTAN soldiers as having implanted devices to suppress emotions and increase loyalty.

          I would like to think that dystopian elements of sci-fi serve as a warning, but I guess there are those who see it as a goal.

        Back in the 90s when some scientists mistakenly thought they had discovered the "gay gene", there were various scams offering to genetically modify your child to be straight. Apparently there is a market for it.

        • Ok, you want a child, great! Have you decided on which you would like? Remember, neither Apple nor Android is inherently better.
    • There are several workin gbrain implants in medical use, such as brain stem implants for the deaf. Do we call cochlear implants brain implants, tied to the auditory nerve as they are? I've not heard of those _reading_ anything from their electrodes: are there any medical experts on this channel?

    • Mostly playing devil's advocate here but what if it's someone who wants their ADHD cured or for a gay person who wants to be straight or for a trans person who would rather treat their mind to eliminate the dysphoria instead of undergoing hormone replacement and affirming surgeries? Is that morally gray? Are they not allowed the agency to decide for themselves what treatments would best fit their own plans in life?

      • by Anonymous Coward

        I believe it is morally gray because you have no way to tell if there is any coercion involved. Its not like there is a history of making people who are different conform or be ostracized and/or killed.

        Teenagers as a general term tend to want to conform to those around them or those they want to be in with. For instance, there is a high school near here where the students are saying they aren't "straight" because straight is boring or everybody has ADHD and wants special help. This could be good, this

      • The ethical dilemma has actually become something of a common trope in sci-fi. An entire X-Men movie was based on a similar premise. Do you sacrifice some of your individuality to better fit in with the collective? What if the "treatment" isn't voluntary? Is society ultimately the better for it?

        If someone wants to have a chip implanted in their head on a consentual basis, they certainly should have the right. The grander societal implications of that though, are something I'll leave for sci-fi authors

        The only reason for a gay person to want to be straight is because some outside force is making being gay a problem for them. Family, society, even the law in some countries. The only morally right thing to do is fix the homophobia.

        The example of a trans person is more compelling because transitioning does often involve medical intervention. Depending on the individual, they might want various hormone therapies, and/or surgery. Treating the dysphoria might be a useful alternative, especially if there are me

        • The only reason for a gay person to want to be straight is because some outside force is making being gay a problem for them. Family, society, even the law in some countries. The only morally right thing to do is fix the homophobia.

          As well, what I have seen in life is that something, somewhere, somehow, with one exception, the gay people that I know are smart and often very talented. Obviously not all, but the early AIDs epidemic took out a lot of awesome folk.

          The example of a trans person is more compelling because transitioning does often involve medical intervention. Depending on the individual, they might want various hormone therapies, and/or surgery. Treating the dysphoria might be a useful alternative, especially if there are medical complications that prevent them using the other options. It would have to be a free choice though, and where family/society/law and medical bills are involved, it never is.

          This is true. Before using the more invasive procedures, the potential "complete" trans person should spend a lot of time dressing and acting like the other gender/sex. I watched a documentary focussing on two men who fully transitioned, and then changed their mind and transiti

      • Mostly playing devil's advocate here but what if it's someone who wants their ADHD cured

        I'll probably be skewered, but ADHD is not a disease. The so called symptoms of ADHD mainly came about because teachers wanted young males to be complaint, and back in the mid 90's, they just put 'em on Ritalin, and all is good. Teacher makes the diagnosis, Doctor Rubber stamps it, and little Johnny is put in his chemical straitjacket.

        I would have been diagnosed because I'm not good at sitting still, even though I have laser focus. I fidget, I get bored easily. I'm annoying as all hell. These kids are ju

        • Hello,
          Lifetime member of Club ADHD here, on Ritalin in the 80's. Max dosage allowable for almost 2 years, then cold turkey and don't bother to explain to the kids what is going to happen. Let them figure it out all on their own years later. Ah the good old days, huh?
          More to my point. It's actually a thing, not made up! Well, at least I can say that in my case. I work as a trainer in a technical field, so my work requires a lot of attention AND attention to detail. After my experience with Ritalin, I patent

          • Will it be this way for everyone? Highly unlikely. But if your point is "it didn't work for Billy, so nobody can use it", I'm afraid you may not understand how medicine and biology work.

            Almost every male in my sons classes were on Ritalin. Now I'm not an expert, but if everyone of a particular sex is ADHD, perhaps there could be an issue in the diagnosis?

            What's truly the most harming? Listening to a bunch of ignorant ass people tell you that you're just doing it for attention...for most of your life.

            It certainly wasn't me saying anything like that. Did you think I was? I consider the overuse of Ritalin and other drugs more a victimization of young people.

            Actual ADHD is a real problem. There was an intern working with me for a while, Our group all loved the guy. Personable outgoing plus enthusiastic. But he really couldn't focus on

        I think we're putting the cart way before the horse on this one. I don't think any of these medical devices are able to alter human behavior or change human thoughts. Generally speaking brain implants fall into two categories: (1) a brain-computer interface to control a computer with your brain, i.e. to enable a paralyzed person to control a wheel chair, a computer, or or some other device, (2) have some kind of therapeutic value in cases of epilepsy, deafness, or blindness. They provide targeted neural st

      The Borg reference is valid. Once you open a channel of communication between a brain and a computing device, there is no limit to the ways in which corporations will use it. We've seen that with Twitter, Facebook, and Google who control certain types of communication. With a direct connection to the brain, the control is far more intimate. Here we talk of temporary use to deal with mental aberrations, but when it becomes practical to add permanent cellular connections, it becomes a much bigger problem.

      No we are not at all. The ethics on this are absolutely clear!

      If you are forcing persons to get a chip in their head so you can modify their behavior - BAD

      If after you have determined and accurately portrayed the risks and likely complications someone chooses to have your chip implanted and to have you modify their behavior in a specific way to correct an illness and that is ALL you do - GOOD

    Demonstrating that the implant can do what it's meant to do is one thing; but then you have to rigorously map the risks and find appropriate mitigations. That takes a very long time, no matter how brilliant the design is.

  • If Neuralink doesn't treat animals well enough to be able to ensure their survival, if they find it acceptable to use separate standards of care from one life to another, human subjects don't seem likely to fare much better than the worst outcomes animals have or had. I guess the Darren Cross type math would be something like, what is the cost of using the same standard of care, does having that guarantee a fast tracked human subject approval and if so, does it limit potential innovation and how much do we
