From the Ted Talk by Donald Hoffman: Do we see reality as it is?

Unscramble the Blue Letters

Now, this is a bit surprising, because to the extent that we think about viiosn at all, we think of it as like a camera. It just takes a picture of objective reality as it is. Now, there is a part of vision that's like a camera: the eye has a lens that focuses an iamge on the back of the eye where there are 130 million photoreceptors, so the eye is like a 130-megapixel caemra. But that doesn't explain the billions of neurons and tlornilis of synapses that are engaged in vision. What are these neurons up to?
