The effect of 3 week chronic haloperidol treatment has been investigated in rats by retention of active avoidance (pole jumping). In the period of dopaminergic supersensitivity, i.e. after withdrawal of haloperidol, pretreated rats showed a better retention of the learned reaction than controls. The results demonstrate that the neuroleptic-induced supersensitivity enhanced not only the spontaneous and stimulated locomotor activity, but also improved the retention of an active avoidance reaction.
通过主动回避(跳杆)保持实验,研究了大鼠为期3周的慢性氟哌啶醇治疗效果。在多巴胺能超敏反应期,即氟哌啶醇撤药后,预处理大鼠比对照组对习得反应有更好的保持。结果表明,抗精神病药物引起的超敏反应不仅增强了自发和刺激的运动活性,还改善了主动回避反应的保持。
