During the reproduction of a conditioned passive avoidance response by albino rats and also during the action of a conditioning stimulus in animals trained by invariable reinforcement of the conditioning stimulus, a significant decrease was found in the noradrenalin content in nuclei of the limbic system and anterior hypothalamus compared with the control. In untrained animals, and also in trained animals subjected to repeated testing in the course of 4 days, the decrease in the noradrenalin content was less marked. Reproduction of the conditioned active avoidence response in a shuttle box did not induce changes in the noradrenalin content.
在白化大鼠条件性被动回避反应的重现过程中，以及在通过条件刺激的恒定强化训练的动物中条件刺激作用期间，发现与对照组相比，边缘系统和下丘脑前部核中的去甲肾上腺素含量显著降低。在未训练的动物中，以及在4天内接受重复测试的训练动物中，去甲肾上腺素含量的降低不太明显。在穿梭箱中条件性主动回避反应的重现并未引起去甲肾上腺素含量的变化。
