The Amazing Brain Of Drosophila

Team member of Functional Brain Imaging and Behavior at the Institute of Neurobiology Alfred Fessard, Jean-René Martin, is interested in Drosophila as neurobiology model, with a multidisciplinary approach, genetic behavior. He has recently presented rather surprising results of his work.

How brain activity was translated into specific behaviors? What are the neurons responsible for these behaviors? Drosophila is an excellent model organism to respond to such questions. In this experimental conference, Jean-René Martin presented a video regarding the amazing brain of flies.

In this video, he analyzes how Drosophila moves in space and time, he shows via this video that the fly avoids the center of an arena (centrophobie) and organizes its route in a very sophisticated manner (e.g. with a fractal-like temporality). The underlying brain structures are also presented and their homologies to mammalian brain structures, such as place cells. Drosophila is an excellent model organism to respond to such questions.

Other types of behavior in flies such as as sleep and addiction to ethanol, nicotine or cocaine can also be studied in Drosophila. In short, Alfred Fessard Jean-Rene Martin wants to make us discover how a fly chooses its way, organizes its time, or how it sleeps! No doubt, his videos are getting popular in scientific community especially with Ben Shaoul.
