A receptor for sNPF is required for appetitive olfactory 2 h memory. A, Pan-neuronal knockdown of the sNPF receptor (UAS-sNPFR-RNAi driven by elav-GAL4) leads to significantly impaired appetitive 2 h memory (**p < 0.01), whereas specific knockdown in the MB with neither OK107-GAL4 nor MB247-GAL4 significantly affects the memory (p > 0.05, n = 10–27). Bars and error bars indicate mean and SEM, respectively. B, Memory impairment after pan-neuronal knockdown of sNPFR is not significantly enhanced by expression of the GAL4 repressor GAL80 in the MB (p > 0.05, n = 10–12). Bars and error bars indicate mean and SEM, respectively.
