    There are two reasons he believes the neocortex could be replaced, albeit only slowly. The first is evidence from rare cases of benign brain tumors, like a man described in the medical literature who developed a growth the size of an orange. Yet because it grew very slowly, the man’s brain was able to adjust, shifting memories elsewhere, and his behavior and speech never seemed to change—even when the tumor was removed.

    That’s proof, Hébert thinks, that replacing the neocortex little by little could be achieved “without losing the information encoded in it” such as a person’s self-identity.

    The second source of hope, he says, is experiments showing that fetal-stage cells can survive, and even function, when transplanted into the brains of adults. For instance, medical tests underway are showing that young neurons can integrate into the brains of people who have epilepsy and stop their seizures.

    “It was these two things together—the plastic nature of brains and the ability to add new tissue—that, to me, were like, ‘Ah, now there has got to be a way,’” says Hébert.

    Very interesting. I’ve also seen research suggesting that the application of stem cells to damaged neural tissue within the spinal cord could repair it, so the idea that you could use a similar approach to actual brain health isn’t such a big leap. But still, wow. I wonder how long it would take for the immature cells to develop into “adult mode” that’s fully integrated into the patients cortex. In order to replace the entire brain, you’d have to do it in like, 8 parts, with years of recovery time in between each surgery. Also there would exist the potential for the new cells to develop into like, a second, smaller brain, if the connections sour or if the new material isn’t stimulated the “right” way.

    The brain renewal concept could have applications such as treating stroke victims

    If this can restore functions to stroke victims again, it’s absolutely amazing.
    If this is vastly successful which remains to be seen, there might be a path format to the longevity part of the idea.

      Well this really exists for those billionaires and rulers. This isn’t for the common person.

      They’re so mad that they’ve removed themselves so far from us and we still share a common experience in death. That’s unfair for them to have to be associated with peasants in such a debasing way. So now they’ll remind us that death is for the poor or at least not living centuries will be for poor.

        I have never understood people who make this argument. In all of history, can you point to a single time when technology wasn’t eventually commercialised and made available to the masses at affordable prices? The billionaires don’t want to keep it to themselves, they want you buying more stuff from them.

        If they’re functional, and we get serious about space or birth control, then no it’s not a problem. But that is another path we can take to really juice the dystopia.

          It will take a very long time indeed before we can reach another habitable planet enough to alleviate an exponentially growing population, and forced birth control will be unpopular, not to mention probably employed as eugenics by those in power against those who aren’t.

                  You’d have zero control over your existence. Someone else would own that station and you’d exist entirely at their whim. They would decide if you get food, air, water, shelter. No real access to nature. I’d rather die.

    Good lord, just let people DIE. Imagine what a rotten place this would be if people with outdated mindsets continued to control the world decades or even centuries after their expiration dates. People were already angry about 80 year old presidential candidates… what happens when they’re 120, or 150?

    No. Absolutely not. Whenever anyone says, “wouldn’t it be great to live forever” remember that means people like trump and Musk are with us forever. Unless people take things into their own hands, but that’s another issue.

      means people like trump and Musk are with us forever.

      But that would also mean their polar opposites would also be with us forever, the objectively best of us

      Maybe the procedure would fix whatever’s wrong with their brains. Like, maybe Trump would slowly regain the ability to form complete sentences. I’m imagining a Flowers for Algernon situation where he wakes up one day, reads his own Wikipedia page, and is briefly ashamed before the non-neural parts of his body crap out.
