Odor reception in antenna and antennal lobe of Drosophila

In early years of neurogenetics of Drosophila, most of us were inclined to believe that behavior of the fruit fly is largely stereotyped and hard-wired. This, at least, was a common prejudice when genetic analysis of olfaction began. We now know that Drosophila like other insects is capable of several types of learning or experience-dependent modification of behavior.
