Abstract

By means of the classical alimentary secretory method, a study was made of the characteristics of formation and preservation of complex systems of conditioned reflexes in dogs with a preliminarily lesioned cortex of the auditory analyser. It has been shown that a rhythmic-mozaic stereotype of conditioned reflexes to acoustic signals can be elaborated in the operated dogs, although conditioned activity is on a very low functional level. However, integration of two complex stereotypes into one single system is not achieved. The formation of a new stereotype in the operated dogs, in contrast to the intact animals, is not accompanied by an enhanced functional state (tone) of the brain, which points to an insufficiency of the self-regulating mechanisms of the cerebral cortex. It is suggested that special activating mechanisms which participate in controlling the functional state of the auditory system, are present in the cortical structures of the auditory analyser.

摘要

通过经典的消化分泌方法,对听觉分析器皮层预先受损的犬类条件反射复杂系统的形成和保存特征进行了研究。结果表明,尽管条件活动处于非常低的功能水平,但在手术犬中仍可形成对声音信号的节律性镶嵌式条件反射刻板模式。然而,无法将两个复杂的刻板模式整合为一个单一系统。与未受损动物相比,手术犬中新刻板模式的形成并未伴随着大脑功能状态(兴奋性)的增强,这表明大脑皮层的自我调节机制存在不足。研究表明,听觉分析器的皮层结构中存在参与控制听觉系统功能状态的特殊激活机制。
