[Participation of the auditory cortex and emotionogenic subcortical systems in the formation and reproduction of conditioned reactions].

Analysis of the activity of several brain structures in conditioned neurographic response taken as an analog of conditioned motor reaction was performed on a model of short-delay defensive reflex with unavoidable reinforcement (immobilized cats). It has been shown that the conditioned electrographic signs may appear in the central nervous system both in the presence and in the absence of conditioned motor reaction. The probability of their occurance increases in the cortex, Zona incerta and in the preoptic area during achievement of conditioned effector reaction. The probability of their appearance in other formations does not change considerably neither in the absence nor in the occurance of conditioned motor reaction. Combinations of brain structures are singled out in which the appearance of conditioned electrographic signs is accompanied by conditioned effector reaction. The optimal variant for its occurance is simultaneous appearance of the conditioned electrographic signs in Zona incerta, in the cortex and in the preoptic area.
