Neural circuits for processing chromatic information are not known. Here, we identified the first-order interneurons downstream of the chromatic channels. Serial EM revealed that small-field projection neurons Tm5 and Tm9 receive direct synaptic input from R7 and R8, respectively, and indirect input from R1–R6, qualifying them to function as color-opponent neurons. Wide-field Dm8 amacrine neurons receive input from 13–16 UV-sensing R7s and provide output to projection neurons. Using a combinatorial expression system to manipulate activity in different neuron subtypes, we determined that Dm8 neurons are necessary and sufficient for flies to exhibit phototaxis toward ultraviolet instead of green light. We propose that Dm8 sacrifices spatial resolution for sensitivity by relaying signals from multiple R7s to projection neurons, which then provide output to higher visual centers.</dcterms:abstract> <dc:creator>Yang, Meiluen</dc:creator> <dc:contributor>Rister, Jens</dc:contributor> <dc:contributor>Ting, Chun-Yuan</dc:contributor> <dc:creator>Lu, Zhiyuan</dc:creator> <dc:creator>Wang, Jing W.</dc:creator> <dc:creator>Meinertzhagen, Ian A.</dc:creator> </rdf:Description> </rdf:RDF>
