Inside the retina, tucked away at the back of the eye, lies an incredibly dense tangle of interconnected neurons. If researchers can map the many connections between these cells, they will be closer to understanding how vision works. To achieve this, they need something more intelligent than even the most powerful supercomputer—citizen scientists.

By playing Eyewire, a game of coloring brain images, citizen scientists can help map the connections of a neural network. No specialized knowledge of neuroscience is required; citizen scientists need only be curious, intelligent and observant. Their input will help scientists understand how the retina functions. It will also be used by engineers to improve the underlying computational technology, eventually making it powerful enough to detect "miswirings" of the brain that are hypothesized to underlie disorders like autism and schizophrenia.
