The intensity of catalepsy produced by haloperidol (0.5 mg/kg), chlorpromazine (10 mg/kg) and morphine (20 mg/kg) given ip was tested in male Wistar rats of age between 3 weeks and 6 months. The cataleptic response was most expressed in the youngest animals, and decreased with age. The results indicate that young rats show higher reactivity of central dopaminergic receptors to the investigated drugs.
对3周龄至6个月大的雄性Wistar大鼠进行腹腔注射氟哌啶醇（0.5毫克/千克）、氯丙嗪（10毫克/千克）和吗啡（20毫克/千克）后产生的僵住症强度进行了测试。僵住症反应在最年幼的动物中表现最为明显，并随年龄增长而降低。结果表明，幼鼠对所研究药物的中枢多巴胺能受体反应性更高。
