The neuroscience of imagination

Imagine, for a second, a duck teaching a French class. A ping-pong match in orbit around a black hole. A dolphin balancing a pineapple. You probably haven't actually seen any of these things. But you could imagine them instantly. How does your brain produce an image of something you've never seen? Andrey Vyshedskiy details the neuroscience of imagination.
