| | Although moths have antennae that are a million times more sensitive to odor than is the human nose, researchers believe that the basic principles of this model olfactory system apply to all animals, including humans. | | | To examine how a plume of odor triggers complex patterns of activity in the brain and how this correlates with the moth's behavior, the researchers devised a method to monitor the olfactory response of a male moth in flight, as he maneuvered through a natural plume of female sex pheromone. | | | The electrical signals that start in the moth's antenna then make their way to the brain, where information is processed. |
