Mean (± SE) percent freezing during the 5 minute test of fear conditioning in Experiment 1. Dosing conditions include Group UD (undisturbed), Group SI (sham-intubated), and Group EtOH (5.25 g/kg/day). Rats from each group were preexposed to Context A (Pre, filled bars) or Context B (No Pre, clear bars). All rats were given an immediate shock 24h later in Context A, followed 24h after that with a test of freezing in Context A. Preexposure to Context A facilitated freezing during the test in Groups UD and SI. Neonatal ethanol treatment (PD4-9) disrupted this context preexposure facilitation effect. Group EtOH showed low levels of freezing in Context A regardless of preexposure condition (Pre vs. No Pre).
