Dissociation and Recovery of a Response Learned under the Influence of Chlorpromazine or Saline.

Rats trained in an avoidance response while under the influence of chlorpromazine and then tested after receiving an injection of saline, or trained after receiving injections of saline and tested after an injection of chlorpromazine, showed greater dissociation and less recovery of the avoidance response than animals that received only injections of saline, or only injections of chlorpromazine during both training and testing sessions.
