Scientists Map Medulla Circuitry in Fruit Flies, Setting Stage for Understanding How Color Vision Is Processed

Thursday, March 27th, 2008
biologists have mapped the medulla circuitry in fruit flies, setting the stage for subsequent research on how color vision is processed. The work, which appeared in the journal Current Biology, will allow future scholarship to explore how color vision is processed in the optic lobe of the fruit fly Drosophila, providing a paradigm for more complex systems in vertebrates.
