ScerGAL4GMR87G01 drives expression mainly in antennal mechanosensory and motor center AMMC PN4 projection neuron, but also drives expression in neurons in the lamina, as well as a subset of ALl1 lineage neurons in the antennal lobe, a neuron innervating the wing neuropil, and descending projections into the terminal abdominal nerve from the last abdominal segment.
