Microinjection of noradrenaline in to the head of the caudate nucleus failed to influence the latent time of the conditioned reaction of avoidance and the muscle tone, but limited the motor activity and considerably increased the value and the latent time of the food-procuring reflex. Serotonin failed to influence the latent time of the conditioned defence reflex and did not alter the motor activity of rats; however, it shortened the latent period of the conditioned motor-food reflex and markedly stimulated the food-procuring reaction. Dopamine inhibited the conditioned food and defence reflex, but markedly stimulated the spontaneous motor activity of rats. The data obtained pointed to differences in the neurochemical mechanisms realizing the conditioned reflex reactions of different biological modality at the level of the caudate nucleus of rats.
向尾状核头部微量注射去甲肾上腺素未能影响回避条件反应的潜伏期和肌张力，但限制了运动活动，并显著增加了获取食物反射的强度和潜伏期。5-羟色胺未能影响条件防御反射的潜伏期，也未改变大鼠的运动活动；然而，它缩短了条件运动-食物反射的潜伏期，并显著刺激了获取食物反应。多巴胺抑制了条件食物反射和防御反射，但显著刺激了大鼠的自发运动活动。所得数据表明，在大鼠尾状核水平上，实现不同生物学模式条件反射反应的神经化学机制存在差异。
