Who says science isn't fun? Visual illusions, such as the dozens you will find in this special issue, make great eye candy. But they also serve a serious purpose for researchers.
How? Illusions push the mysterious and wondrous brain into revealing its secrets.
From the confusing and fragmentary inputs gathered by our senses, our brains create our seemingly fluid conscious perceptions and a sensible narrative of the world around us. Brains do not, however talk to us about how they perform those impressive tasks. Scientists can learn a lot by using imaging equipment and by making other observations. But sometimes they also have to "trick" brains, the better to
probe perception. That's where illusions come in.
