And by the way, when you look at human infants, they have tons of dream sleep at the beginning when their brains are very plastic. And as they age, the amount of dream sleep goes down.

At the moment, there are 19 papers that have cited this and discussed this. And I think it's right. I mean, look, everything can be wrong. Everything is provisional. But it's the single theory that is quantitative. It's the single theory about dreams that says not only here is a idea for why we dream, but we can compare across species and the predictions match exactly. No one would have...

suspected that you'd see a relationship between, you know, how long it takes you to walk or reach adolescence and how much dream sleep you have. But it turns out that is spot on.

Given that all the data running around in the brain is just data and the brain doesn't know where it came from, all it knows is, oh, here are electrical spikes, and it tries to figure out what to do with it. I got really interested in this idea of sensory substitution, which is, can you push information into the brain via an unusual channel?

Originally, we built a vest that was covered with vibratory motors. and we captured sound for people who are deaf. So the vest captures sound, breaks it up from high to low frequency, and you're feeling the sound on your torso. By the way, this is exactly what the inner ear does. It breaks up sound from high to low frequency and ships that off to the brain.

So we're just transferring the inner ear to the skin of the torso, and it worked. People who are deaf could come to hear the world that way. So I spun this out of my lab as a company, Neosensory, and we shrunk the vest down to a wristband, and we're on wrists of deaf people all over the world. The other alternative for somebody who's deaf is a cochlear implant, an invasive surgery.

This is much cheaper and does as good a job.

It's actually just vibratory motors. So it's just like the buzzer in your cell phone, but we have a string of these buzzers all along your wrist. And we're actually taking advantage of an illusion, which is if I have two motors next to each other and I stimulate them both, you will feel one virtual point right in between. Hmm.
