Motivational effects of self-administered ethanol have rarely been studied in preweanling rats due primarily to the lack of age-appropriate operant tasks. The present experiments assessed the hedonic effects of intraoral ethanol in infant rats self-administered by activating a touch sensor. On postnatal day (PD) 13 pups were pre-exposed to the drug's pharmacological and/or sensory effects. Operant sessions were conducted during PDs 14-16 (Experiments 1 and 2). Paired animals were placed in… CONTINUE READING
