Additional Information
Statement
Reference

ScerGAL4Ras64B.PW drives widespread expression in the third instar larval and adult brain. There is extensive colocalisation with Alk protein, namely in the mushroom body calyx, antennal lobe and subesophageal ganglion. ScerGAL4Ras64B.PW also labels the lobe system of the mushroom bodies.
