So this was not an original idea for us, except to try this on the wrist. And it works equally as well.

For people who are blind, for example, there are a few different approaches to this. One is called the brain port, and that's where, for a blind person, they have a little camera on their glasses, and that gets turned into... little electrical stimulation on the tongue. So you're wearing this little electro-tactile grid on your tongue and it tastes like pop rocks sort of in your mouth.

Blind people get pretty good at this. They can navigate complex obstacle courses or throw a ball into a basket at a distance because they can come to see the world through their tongue, which if that sounds crazy to It's the same thing as seeing it through these two spheres that are embedded in your skull.

It's just capturing photons and information about them, figuring out where the edges are, and then shipping that back to the brain. The brain can figure that out. There's also a colleague of mine that makes an app called Voice. It uses the phone's camera and it turns that into soundscape. So if you're moving the camera around, you're hearing, you know, it sounds like a strange cacophony.

But it doesn't take long, even for you as a sighted person, to get used to this and say, oh, okay, I'm turning the visual world into sound. And it's starting to make sense when I pass over an edge or when I zoom into something, the pitch changes, the volume changes. There's all kinds of changes in the sound quality that tells you, oh yeah, now I'm going to close something. Now I'm getting far.

And here's what the world looks like in sound. Coming up after the break. There's really no shortage of theoretical ideas in neuroscience, but fundamentally, we don't have enough data.

What they're doing is they're putting electrodes into the brain to read from and talk to the neurons there.

That is correct. Everything we've been talking about so far with sensory substitution, that's a way of pushing information in and non-invasive. And what Neuralink is, you have to drill a hole in the head to get to the brain itself, but then you can do reading and writing invasively. That actually has been going on for 60 years now. The language of the brain is electrical stimulation.
