#438 – Elon Musk: Neuralink and the Future of Humanity

Vision's a little deeper. And so this gets to your question about how deep can you get. To do vision, we can't just do the surface of the brain. We have to be able to go in, not as deep as we'd have to go for DBS, but maybe a centimeter deeper than we're used to for hand insertions. And so that's work in progress. That's a new set of challenges to overcome.

Yeah, I mean, the goal there comes from experience. I mean, we stand on the shoulders of people that... made Utah rays and used Utah rays for decades before we ever even came along.

Neuralink arose partly, this approach to technology arose out of a need recognized after Utah rays would fail routinely because the rigid electrodes, those spikes that are literally hammered using an air hammer into the brain those spikes generate a bad immune response that encapsulates the electrode spikes in scar tissue, essentially.

And so one of the projects that was being worked on in the Anderson lab at Caltech when I got there was to see if you could use chemo therapy to prevent the formation of scars. Things are pretty bad when you're jamming a bed of nails into the brain and then treating that with chemotherapy to try to prevent scar tissue, it's like, maybe we've gotten off track here, guys.

Maybe there's a fundamental redesign necessary. And so Neuralink's approach of using highly flexible, tiny electrodes avoids a lot of the bleeding, avoids a lot of the immune response that ends up happening when rigid electrodes are pounded into the brain.

And so what we see is our electrode longevity and functionality and the health of the brain tissue immediately surrounding the electrode is excellent. I mean, it goes on for years now in our animal models.
