[Formation of combined stereotypes of systems of secretory conditioned reflexes]. / Osobennosti formirovaniia kombinirovannykh stereotipov sistem sekretornykh uslovnykh refleksov

A rhythmic stereotype, followed by a rhythmic-mozaic one of positive and inhibitory conditioned secretory reflexes were successively elaborated in dogs with stabile stereotype of three heteromodal randomely organized systems. Thus a combined stereotype was formed of five randomely and stereotypically organized systems of conditioned reflexes, achieved at intervals of 24 hours or longer in a regular sequence. It has been shown that in the course of formation of the combined stereotype the general functional state (tone) of the cerebral cortex is enhanced. The preliminarily formed specialized systemic nervous process with a similar structure is of major importance for the rate of formation of the complex rhythmic-mozaic stereotype.

[Formation of two systems of conditioned reflexes with random alteration of stimuli]. / Obrazovanie dvukh sistem uslovnykh refleksov pri sluchainom cheredovanii razdrazhitelei

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.
