From the Ted Talk "Ed Boyden: A light switch for neurons"

Unscramble the Blue Letters

So when I started in ocnreuecsnie 11 resya ago, I had trained as an electrical engineer and a physicist, and the first thing I thought about was, if these neurons are electrical devices, all we need to do is to find some way of driving those electrical changes at a idtcenas. If we could turn on the electricity in one lecl, but not its neighbors, that would give us the tool we need to activate and shut down these different cells, figure out what they do and how they contribute to the networks in which they're embedded. And also it would allow us to have the ultra-precise control we need in order to fix the circuit computations that have gone awry. Now how are we going to do that? Well there are many molecules that exist in nature, which are able to convert light into electricity. You can think of them as little nopertsi that are like solar cells. If we can install these molecules in neurons somehow, then these neurons would become lretealilycc drivable with light. And their neighbors, which don't have the molecule, would not. There's one other magic trick you need to make this all happen, and that's the ability to get htgli into the brain. And to do that — the brain doesn't elef ipan — you can put — taking advantage of all the effort that's gone into the etenintr and communications and so on — tcalpio fibers connected to lasers that you can use to activate, in animal models for example, in pre-clinical studies, these neurons and to see what they do.

So when I started in neuroscience 11 years ago, I had trained as an electrical engineer and a physicist, and the first thing I thought about was, if these neurons are electrical devices, all we need to do is to find some way of driving those electrical changes at a distance. If we could turn on the electricity in one cell, but not its neighbors, that would give us the tool we need to activate and shut down these different cells, figure out what they do and how they contribute to the networks in which they're embedded. And also it would allow us to have the ultra-precise control we need in order to fix the circuit computations that have gone awry. Now how are we going to do that? Well there are many molecules that exist in nature, which are able to convert light into electricity. You can think of them as little proteins that are like solar cells. If we can install these molecules in neurons somehow, then these neurons would become electrically drivable with light. And their neighbors, which don't have the molecule, would not. There's one other magic trick you need to make this all happen, and that's the ability to get light into the brain. And to do that — the brain doesn't feel pain — you can put — taking advantage of all the effort that's gone into the Internet and communications and so on — optical fibers connected to lasers that you can use to activate, in animal models for example, in pre-clinical studies, these neurons and to see what they do.
