ScerGAL4^{CG42368-NP1183} is strongly expressed in projection neurons that arborize in larval antennal lobe glomeruli 24a and 45a, but weakly in glomeruli 1a. In the larval mushroom body calyx, ScerGAL4^{CG42368-NP1183} is strongly expresses in a pair of glomeruli identified as A3 and L11, in one or more interneurons that ramify throughout the posterior antennal lobe, and extensive labelling is also seen in cell bodies and processes innervating the neuropils that lie ventral and lateral to the calyx.
