Inhibition (using shi1.UAS at 33[o]C) of Scer\GAL4GMR92F10 cells in adults during testing significantly reduces 1 h and 3 h aversive memory, compared to controls; reduction in 3 h aversive memory is no longer seen when inhibition is restricted to a smaller subset of Scer\GAL4GMR92F10 cells using Scer\GAL80Mef2.mb247; inhibition of Scer\GAL4GMR92F10 cells has no effect on naive preferences for odors, shock or sugar, compared to controls.
