In Jonathan Weiner's Time, Love, Memory: A Great Biologist and His Quest for the Origins of Behavior, flies are used to experiment on to study the inheritance of genes and what controls behavior.

The most surprising thing was the flies' ability to survive. In one part of the experiment, they cut off a fly's head to observe the effect on its behavior. The result was that it learned faster to avoid certain objects/things that would cause pain than a fly whose head wasn't cut off. The fly whose head was cut off lived for two weeks or so before it died. We certainly can't live for that long if our heads were decapitated!
