Rats were trained to discriminate 0.04 mg/kg fentanyl from saline in a 2-lever procedure, and to discriminate 10 mg/kg pentobarbital from saline in a maze procedure. Stimulus generalization experiments in rats trained in this double discrimination indicate that the internal cues produced by these training drugs can be conditioned to the external stimulus conditions associated with the different discrimination procedures.
大鼠通过双杠杆程序接受训练，以区分0.04毫克/千克的芬太尼和生理盐水，并通过迷宫程序区分10毫克/千克的戊巴比妥和生理盐水。对接受这种双重辨别训练的大鼠进行的刺激泛化实验表明，这些训练药物产生的内部线索可以与不同辨别程序相关的外部刺激条件建立条件反射。
