Effect of Mvl knockdown in specific neuronal populations. (A) Feeding choice assay. GAL4 drivers: Poxn, all gustatory receptor neurons; TH, dopaminergic neurons; Tdc2, octopaminergic neurons; Cha, cholinergic neurons; dimm, neuropeptidergic neurons; Npf, Neuropeptide F neurons; Akh, Adipokinetic hormone neurons; Tim, circadian neurons. (B) General feeding-drive control experiment. Genotypes as in A. See Tables S4 and S5 for statistics.
