Conditioning of the Activity Effects of Drugs

  • Roy Pickens

A number of studies have reported conditioning of the activity effects of drugs. In these studies, the eliciting or unconditioned stimulus (US) was an injection of a drug which produced a change in activity, and the conditioned stimulus (CS) was a neutral event, such as placing the animal in an activity cage, which was paired with the drug injection. As a result of the CS-US pairing, the presentation of the CS alone was found capable of producing a change in activity similar to that elicited originally by the drug itself.
