Additional Information
Statement
Reference

Adult expression is observed in the ab3A neuron of the ab3 functional type of the large sensillum basiconium in the dorsal medial region of antennal segment 3. These neurons project to antennal glomerulus DM2. More sensilla are labeled in female flies than in male flies. The pattern is essentially indistinguishable from that of ScerGAL4Or22a.8010.
