  • Title: [Relation between responses of auditory cortex neurons in the cat and the signal significance of acoustic stimuli in the instrumental alimentary reflex].
    Author: Tal'nov AN.
    Journal: Neirofiziologiia; 1985; 17(2):212-21. PubMed ID: 4000304.
    Abstract:
    Responses of 93 neurons to single sound clicks and to a series of 10 clicks with frequency 1000 c as well as reactions of 66 neurons after working out of conditioned reflex were studied in chronic cats. The clicks became a positive conditioned stimulus and the series of clicks were used as a negative differential stimulus in the reflex. It was shown that the working out and realization of the differentiation did not lead to amplification of inhibition in the auditory cortex neurons. Responses of neurons to positive as well as to negative conditioned stimuli underwent the same changes after learning that can be considered as evidence of the similar role of auditory neurons in the instrumental reflex realization and its differential inhibition. The existence of neuronal groups responding by excitation and inhibition only to stimulus with definite signal meaning is supposed to be important for the process of differentiation.
