Mice know fear. And they know to fear the scent of a predator. But how do their brains quickly figure out with a sniff that a cat is nearby?
It’s a complex process that starts with the scent being picked up by specific receptors in their noses. But until now it wasn’t clear exactly how these scent signals proceeded from nose to noggin for neural processing.
