  • Title: [Inhibitory conditioned reflex of the tonic type].
    Author: Borukaev RK.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1983; 33(2):277-84. PubMed ID: 6858387.
    Abstract:
    Physiological parameters of dogs conditioned reactions were studied, elaborated in response to experimental situations stimuli: in one case the animals experienced painful electrocutaneous stimulation (defensive situation), in the other one--they did not (neutral situation). One of these reflexes, that appearing in the defensive situation, may be considered as positive, the other one (in neutral situation)--as inhibitory. In conditions of transswitching, positive tonic conditioned reflex (TCR) determines positive signal significance of phasic (trigger) stimulus and inhibitory TCR--the negative significance (of the same stimulus). By conditions of elaboration, the inhibitory TCR resembles two types of internal inhibition--differential and delayed inhibition. At the same time the inhibitory TCR differs in such an important property as long duration. It determines its special functional inhibition. It is assumed that in integral behaviour TCR (positive and inhibitory) is a conditioned mechanism of regulation of levels of wakefulness and emotional states.
