abstract

  • The net reinforcing/aversive properties of cholecystokinin (CCK) were measured using a conditioned place-preference paradigm. Both sated and food-deprived rats showed a dose dependent aversion to an environment previously paired with CCK that was correlated with the effects of CCK on feeding. In contrast, all rats showed a conditioned preference for an environment previously paired with food. These results demonstrate the aversive properties of CCK and suggest that the decrease in feeding that follows peripheral administration of CCK results from a CCK-induced malaise.
