Zusammenfassung:
Insects are very smell-dependent which makes them prime candidates for studying how the sense of smell works and how it influences behavior. In this video, BILL S. HANSSON describes how the research team studied the olfactory system of flies. Following the whole process from molecule detection and the reaction of the nerves to the outcome of behavior the researchers found a line in the fly's brain that identifies bad odors and leads the fly to avoid these smells as they indicate something is toxic. Because the olfactory systems of all species work in a similar way, the findings can be used to draw conclusions to the human sense of smell.
