Abstract Neurobiology and neuroinformatics are two corresponding disciplines. One topic of interdisciplinary research is visual pattern discrimination. Selecting visually guided prey-catching behaviour of the common toad, this film shows: 1. by which features prey objects can be discriminated from nonprey, 2. how feature related information is processed in different brain regions in a parallel interactive manner, 3. that the feature assignment principle can be illustrated by means of a simple model of a neuronal circuit, in cartoon motion pictures, 4. how this model can be tested, 5. that object discrimination may be modified by associative learning, learning involved brain structures are approached, which leads to an extension of the model, 7. that some characteristics of object discrimination can be simulated with the aid of an artificial neuronal net, and 8. that such a net can tell a robot, for example, to sort objects moving on a conveyor belt.
