Outline of Final Research Achievements

Many animals can discriminate color based on the activities of several photoreceptor classes that have a distinct spectral sensitivity. However, neural mechanisms underlying color vision are not yet fully understood. Drosophila melanogaster offers a good model system for deciphering the neural basis of color vision due to the similarity of the early visual circuits with humans, the numerical simplicity of the circuits and the availability of rich genetic tools. In this study, as a first step toward understanding the neural mechanisms of color vision, we aimed to establish electrophysiological recordings from CNS neurons of the fly brain involved in color vision. In addition to the electrophysiological approach, we established a behavioral experiment to evaluate the color discrimination ability of the fly.
