Tiny twitches of their whiskers allow rats to “see” in the dark, helping them to find their way home or back to a particularly savory garbage pile.

Now, after years of trying, U.S. researchers said on Wednesday they have caught the whole thing on film, allowing them finally to understand what the rat whiskers are telling the brain.

“There is a huge amount of work but nobody really has understood what it is they are actually seeing with their whiskers,” said Christopher Moore, a neuroscientist at Massachusetts Institute of Technology in Boston, whose study appears in the journal Neuron.
