Two heteromodal systems of secretory positive and inhibitory reflexes were elaborated in non-learned dogs to conditioned stimuli presented according to a four-digit table of random figures; then a third system was elaborated. All the systems were presented with one-day intervals in strict alteration (in a stereotype). It has been shown that the formation of a stereotype out of systems of secretory conditioned reflexes, organized at random, is characterized by an enhanced general functional state (tone) of the brain. A comparison of the results of the present work with previous investigations of simultaneous formation of two heteromodal rhythmical stereotypes leads to the conclusion that the structure of the systems in which the conditioned reflexes are formed is the major factor, not the structure of the reflexes.
在未经过训练的狗身上，针对按照四位随机数字表呈现的条件刺激，构建了两个分泌性阳性和抑制性反射的异模态系统；然后构建了第三个系统。所有系统以一天的间隔严格交替（以固定模式）呈现。结果表明，由随机组织的分泌性条件反射系统形成的固定模式，其特征是大脑的一般功能状态（兴奋性）增强。将本研究结果与先前关于同时形成两种异模态节律性固定模式的研究结果进行比较，得出的结论是，形成条件反射的系统结构是主要因素，而非反射的结构。
