  • Title: [Formation of two systems of conditioned reflexes with random alteration of stimuli].
    Author: Murav'eva NP.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1976; 26(3):503-10. PubMed ID: 941497.
    Abstract:
    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.
