ScerGAL4NP3481 drives expression in around 10 uniglomerular antennal lobe projection neurons. Their cell bodies are positioned in the anterior-dorsal part of the antennal lobe and projections are detected to seven different glomeruli including VM7d. Labeling is also detected in one multiglomerular projection neuron. Its cell body is positioned ventrally and it innervates 14 different glomeruli including VC3l, VM6, VC5, VP1, VP4, VP2 and VP3.
