title: Operant responding for ethanol in rats with a long-term history of free-choice ethanol drinking.
abstract: Wistar rats were allowed to drink ethanol in a two-bottle (water vs 2-8% v/v ethanol) and then in a three-bottle choice paradigm (water vs 8% ethanol vs 16% ethanol, v/v). After 7 months of free access to alcohol, the subjects were trained to respond for 8% ethanol in an operant procedure. No relationship was found between prior alcohol drinking and lever pressing for ethanol.
