    Notes: Abstract Preference for ethanol in rats, overcoming the problem of a position habit, was assessed in a one-lever and two-liquid chamber. Performance in lever pressing for ethanol of different concentrations (2.5%, 5.0%, and 15.0%) and for water, as well as the amount of liquid intake, were recorded. Evidence of ethanol preference was observed by both the lever press and consumption measures when the concentration was 2.5%. Water preference was evident at higher concentrations. The present method proved to be a useful method for studying ethanol preference in rats.

    Voluntary ethanol consumption in the absence of hunger and thirst drives (1986)

    Notes: Abstract Voluntary ethanol consumption in Wistar rats was examined in a choice situation between water and ethanol. In each session continuing over 5 days, ethanol at five different concentrations from 2.5 to 45% (v/v) and water were given as reinforcers for FR-30 lever-press responses during 12-h light and 12-h dark periods with food available. The results indicated that rats preferred 2.5–5% ethanol to water, but water to 30 or 45% ethanol. Daily net ethanol consumption per kg body weight increased monotonically as a function of its concentration and reached a mean value of 9.08 g/kg at 45%. Rats drank most of the ethanol and water during the dark period, despite the large amount of ethanol intake occurring at that time.
