Exposure to psychostimulant drugs of abuse such as amphetamine can result in long-lasting “sensitization” of reward-directed behavior, such that subjects display enhancements in behavior directed by and toward rewards and reward-predictive cues (i.e. – “incentive sensitization”). The purpose of these experiments was to determine the degree to which such sensitization resulting from chronic amphetamine exposure influences both appetitive and consummatory food-motivated behavior. Adult male Long-Evans rats received daily i.p. injections of d-amphetamine (2.0 mg/kg) or saline vehicle for five consecutive days. This amphetamine exposure regimen produced lasting sensitization to the acute locomotor stimulant effect of the drug. One month after drug exposure rats were tested for instrumental responding (lever pressing) for food reward under various response schedules. Two months after drug exposure, rats were tested for food consumption in a discriminative Pavlovian context-potentiated eating task, involving pairings of one context with food and another context with no food. Amphetamine-exposed rats showed significantly greater instrumental responding for food reward than saline controls, particularly under conditions of high response ratios. In the potentiated eating task, testing under conditions of food satiation revealed that amphetamine-exposed rats ate significantly more than saline controls in the food-paired context. These experiments demonstrate that amphetamine exposure can cause enduring increases in both appetitive and consummatory aspects of natural reward-directed behavior. Such long-lasting incentive sensitization could account in part for the propensity for relapse in drug addiction, as well as for reported enhancements in non-drug reward-related behavior.
