| dc.description | Michael H. Dickinson is the Esther M. and Abe M. Zarem Professor of Bioengineering and Aeronautics at the California Institute of Technology. His lab studies the neural and biomechanical basis of behavior in the fruit fly, Drosophila. They strive to build an integrated model of behavior that incorporates an understanding of morphology, neurobiology, muscle physiology, physics, and ecology. Although their research focuses primarily on flight control, they are interested in how animals transform sensory information into a code that controls motor output and behavior. | en_US |

| dc.description.abstract | Over 400 million years ago, a group of tiny six-legged creatures evolved the ability to fly—an event that fundamentally transformed our planet. Equipped with the ability to fly, insects underwent an extraordinary radiation and have dominated every terrestrial ecosystem ever since. In order to employ fly effectively, these ancient insects must have possessed the rudimentary ability to take off, fly stably, disperse, forage, and land — a core set of behavioral modules that constitute a ‘Devonian Toolkit’. The fact that the basic architecture of the nervous system is remarkably uniform across species, further suggests that many behaviors of modern insects are deeply rooted in a common evolutionary history. My lab is attempting to reconstruct the behavior and ecology of ancestral insects through investigations of the common fruit fly, Drosophila melanogaster. Most experiments on fly behaviors have been confined to small laboratory chambers, yet the natural history of these animals involves dispersal that takes place on a much larger spatial scale. New release-and-recapture experiments in the Mojave Desert confirm that flies can navigate over 10 kilometers of open landscape in just a few hours. Such excursions are only possible because flies can actively maintain a constant heading. In this talk, I will discuss a hierarchy of neural mechanisms that enable flies to maintain a stable course in the face of external and internal perturbations. Collectively, this new research provides insight into ancient sensory-motor modules that have helped make insects the most successful group of animals in the history of life. | en_US |
