Between alerting us to danger and allowing us to spot prey, vision keeps many animals, including humans, alive. But exactly how does this important sense work, and why is it easier for us to spot movement of small objects in our field of vision, than to notice other things? The complexity of the neural network that supports vision has long baffled scientists.

Now, with a new technology and support from the National Science Foundation, Claire Wyart in Ehud Isacoff's lab at the ...
