In the real world, odors don't happen one puff at a time. Animals move through, and subsequently distort, plumes of odor molecules that constantly drift, changing direction as the wind disperses them. Now, by exploring how animals smell odors under naturalistic conditions, scientists reveal that the brain encodes these swirling, and complex patterns of molecules using surprisingly little neural machinery. The findings suggest a new theory of how animals smell.
