Nothing makes sense in the neurosciences except in the light of behavior .
This fundamental insight constitutes the ultimate criterion for brain performance. Thus, the common functional organization of brains must be described in behavioral terms and can only be tested by behavioral experiments. The challenge for the behavioral scientist is to describe, in these terms, the relevant brain processes which lie behind the level of overt behavior. Drosophila offers us a wide variety of behaviors which can serve as indicators of the events inside the brain of a wildtype individual as well as of the functional alterations in brains of genetically manipulated individuals. Among other experimental designs we use Buridan's Paradigm , the Locomotion Recorder , the Heat Box and the Flight Simulator for our main topics.
