Figure 1.
Mean (+/- SEM) change in freezing (%CS freezing - %pre-CS freezing) observed during the test session on postnatal day (PD) 34 from Experiment 1. Animals were trained with delay or trace conditioning procedures on PD 30. On PD 31-33, half of the subjects were given a single daily dose of 2.5 g/kg i.g. ethanol and the other half was given water (0.0 g/kg). Post-training ethanol disrupted trace conditioned responding, but had no effect on delay.
