Additional Information
Statement
Reference

ScerGAL4RhoGAP18B-1 drives expression in the adult mushroom body, parts of the pars intercerebralis, central complex and gnathal ganglion as well as in a subset of antennal lobe projection neurons that arborize on glomeruli DA1 and DM3. The expression pattern is essentially identical to ScerGAL4NP1514 (whir[3]), but at a lower level of expression.
