And the same time, he is sending a mental message to the second rat that didn't see any light, and the second rat, in 70 percent of the times is going to press the left lever and get a reward without ever experiencing the light in the retina.
Light perception happens in a paper-thin layer of cells, called the retina, that covers the back of your eyeball.
In the retina, there are two different types of light-detecting cells: rods and cones.
Well, the rod cells in your retina take over in low-light conditions.
All of these objects flow outwards and they leave trails, or blur lines, on your retina.
But the only way your brain can do that, is that it has to, instead of generating a perception of the way the world was when light hit your retina, it has to do something fancier.
Here are the cues of motion, the kinds of cues that you get on your retina when things are moving.
It's not ideal for the human eye to have a blind spot where the optic nerve exits the retina, but that's how it developed, starting from a simple photoreceptor cell.
When we see, it's because the energy of light stimulates a receptor in our eye called the retina.
Our retina are only sensitive to light with a very small range in energy, and so we call that range of light visible light.
Inside our retina are special receptors called rods and cones.
If light shines on us that has an energy our retina can't measure, we won't be able to see it.
Light that is too short wavelength or high energy gets absorbed by the eye's surface before it can even get to the retina, and light that is too long wavelength doesn't have enough energy to stimulate our retina at all.
Floaters are tiny objects that cast shadows on the retina, the light-sensitive tissue at the back of your eye.
They become more visible the closer they are to the retina, just as holding your hand closer to a table with an overhead light will result in a more sharply defined shadow.
Here, you are not seeing shadows but little moving windows letting light through to your retina.
The windows are actually caused by white blood cells moving through the capillaries along your retina's surface.
Crystalline proteins forming at the surface created a structure that proved useful in focusing light at a single point on the retina.
For example, the human retina is inverted, with light-detecting cells facing away from the eye opening.
This results in a blind spot, where the optic nerve must pierce the retina to reach the photosensitive layer in the back.
The similar looking eyes of cephalopods, which evolved independently, have a front-facing retina, allowing them to see without a blind spot.
She knows how different wavelengths of light stimulate three types of cone cells in the retina, and she knows how electrical signals travel down the optic nerve into the brain.
She thanked me for the donation, and she explained that she is studying retinoblastoma, which is a deadly cancer of the retina that affects children under the age of five, and she said that yes, we were invited to visit her lab.
Arupa also explained that she is using Thomas's retina and his RNA to try to inactivate the gene that causes tumor formation, and she even showed us some results that were based on RES 360.
With a handheld strobe, they can explore the sculpture, and discover thousands of cell-sized robots hard at work, leaping in and out of the optic nerve, being deployed to the retina to repair it.
And I'm going to show you a system that we designed to model the retina, which is a piece of brain that lines the inside of your eyeball.
Instead of doing this in software, or doing those kinds of algorithms, we went and talked to neurobiologists who have actually reverse engineered that piece of brain that's called the retina.
The retina chip that we designed sits behind this lens here.
What you notice here is that these snapshots taken from the output of the retina chip are very sparse, right?
And this is what the retina is doing, and it's doing it just with the circuitry, and how this network of neurons that are interacting in there, which we've captured on the chip.
