A classically conditioned cocaine cue acquires greater control over motivated behavior in rats prone to attribute incentive salience to a food cue

摘要

RationaleCues associated with rewards bias attention towards them, and can motivate drug-seeking and drug-taking behavior. There is, however, considerable individual variation in the extent to which cues associated with rewards acquire motivational properties. For example, only in some rats does a localizable food cue become attractive, eliciting approach towards it, and “wanted”, in the sense that it serves as an effective conditioned reinforcer.
