| Abstract: | Experiments on rats have shown that droperidol, fluorophenazine, haloperidol, triphtazine, aminazin, thioridazin and clozapin are capable to reduce pedal self-stimulation from the ventral tegmen of the midbrain, which is not related to the cataleptogenic action of the neuroleptics or to their effect on the actuating motor mechanisms but is a consequence of the action on the emotional-positive reinforcement system. A significant positive correlation was disclosed between the ability of the neuroleptics given in effective doses to reduce pedal self-stimulation from the ventral tegmen and their cataleptogenic action. |
