A single appetitive training session forms memory that requires new protein synthesis. Flies were either fed 35 mm CXM in 3% ethanol solution (open squares) or 3% ethanol alone (filled diamonds) during a 16 h starvation period before training. All flies were then trained, and different populations were tested once for odor memory 1, 3, 6, 12, or 24 h later. Error bars are SEM. Asterisks denote a significant difference (p < 0.05) at that time point from the performance of the other group. All n ≥ 8.
