Adolescent ethanol re-exposure augments the behavioral effect of prior fetal exposure. Mean composite reflexive sniffing index values (± sem) for all adolescent observer animals that received prenatal ethanol exposure as a function of adolescent treatment. Relative to prenatal experience alone, animals with subsequent ethanol re-exposure in adolescence display altered responses to ethanol odor at this age. ET/ET = prenatal and adolescent ethanol exposure. ET/H2O = prenatal ethanol exposure and adolescent water exposure.
