Are 'optical illusions' illusions?
I am fascinated with the idea of ghostly like structures or in other words, electrical objects. I think we are inclined to think that brain works linearly or only in 2D. But as you have observed, brain has its 3D built literally with neurons. So when we change our perspective from 2D to 3D, we can observe the direct relation of outside stimulus represented inside 3D brain. I think, that idea can change the way we understand the works of the brain; brain will not be that much mysterious anymore.
When Markram mentioned about moon illusion in TED Talks, I remembered something: The neurological basis of Muller-Lyer illusion tells us that the neurons stimulated by extrovert arrows are longer than the neurons stimulated by introvert arrows. That means the number of neurons fired for extrovert arrows is more than the introvert arrows. So where is the illusion? In this case there is no other algorithm interfering to perceive equal lines as different, it is physically different for the brain. And it must be physically different for the retina if there is no other interfering algorithm from eye to neuron. There is no "trick of perception". That must be exactly the same for moon illusion as I think. Just look at the brain, for a reason, may be rational or irrational, although we learn about the mystery of the illusion, it stays. Indeed there is no mystery of it, it is physically in the brain as we see it.
