Expression of tauUAS.A.Tag:FLAG under the control of Scer\GAL4GMR13F02 or Scer\GAL4c739, in combination with a Gal80[ts] transgene to restrict expression to the adult stage, significantly reduces aversive olfactory 24 h memory following spaced training, compared to controls; in the case of Scer\GAL4GMR13F02, there is no effect on 3 min memory or 24 h memory following massed training, compared to controls; in the case of Scer\GAL4GMR13F02, but not Scer\GAL4c739, habituation to electric shocks is significantly increased after 2 shocks, compared to controls, but there is no effect with either driver after 15 shocks.
