Description

Animals owe much of their fitness to their behavior. They often have a large behavioral repertoire that they have to manage. For this, they need their brain. Using Drosophila as the study case, this chapter depicts animals as autonomous agents and the brain as a behavioral organizer. Behavior is active. It is generated for its consequences. It serves to change or restore the animal’s condition, with no guarantee for improvement. There are two kinds of activity—reactivity and initiating activity. If in a special situation, the animal’s repertoire contains a behavior with sufficiently positive inferred outcome and this is activated, it is called a reaction. Most situations, however, provide no special cues for which reactions would be available. Animals do not have to wait. They can activate behaviors ‘by themselves,’ in search of one with positive outcome.
