Or in regular, but in three dimensions, where the thing that changes is the light, not the pixels' position.
When you turn on the light, actually you see this.
It doesn't need light.
But on this side, it has sugary Gummy Bears, to diffuse the light more slightly.
You can imagine that then maybe you can use a pure protein to guide light, and so we've made optical fibers.
Well, there are many molecules that exist in nature which are able to convert light into electricity.
If we install these molecules in neurons somehow, then these neurons would become electrically drivable with light, and their neighbors, which don't have this molecule, would not.
There's one other magic trick you need to make this happen: the ability to get light into the brain.
There's a certain alga that swims in the wild, and it needs to navigate towards light in order to photosynthesize optimally.
And it senses light with a little eyespot, which works not unlike how our eye works.
In its membrane, or its boundary, it contains little proteins that indeed can convert light into electricity.
When blue light hits it, it opens a little hole and allows charged particles to enter the eyespot; that allows this eyespot to have an electrical signal, just like a solar cell charging a battery.
And the next thing you know, you have a neuron which can be activated with light.
And then when you shine light on the entire network, just that cell type will be activated.
And when the light turns off, these cells go back to normal; there don't seem to be adverse events.
To do that, we came up with a very simple paradigm in collaboration with the Fiorillo group, where, if the animal goes to one side of this little box, it gets a pulse of light.
And we'll make different cells in the brain sensitive to light.
The animal goes to the right-hand side and pokes his nose there and gets a flash of blue light every time he does it.
A flash of light occurs.
And the same tone is going to play, and the light is going to flash again.
We found molecules called halorhodopsins or archaerhodopsins, that respond to green and yellow light.
And they do the opposite of the molecule I told you about before, with the blue light activator, channelrhodopsin.
This animation tries to explain this concept where we made these cells sensitive to being turned off with light, and we beam light in, and just for the time it takes to shut down a seizure, we're hoping to be able to turn it off.
So far, we haven't seen overt reactions of any severity to these molecules or to the illumination of the brain with light.
On the other hand, light can still get into the eye.
Light is converted to electricity on them.
But the implications of being able to control seizures or epilepsy with light instead of drugs and being able to target those specifically is a first step.
With blue light, we can drive information, and it's in the form of a one.
So the challenge was, how are we going to bring light and expose these things?
And by night, artificial light in each one emanates and comes out to the outside.
