[Mechanism of the effect of neuronal response suppression in the auditory nerve during exposure to bitonal stimuli].

It is supposed that interreceptor currents existing due to microphonic and summating potentials are the exiting factors for the neuron endings of the cochlear nerve. A model is proposed of the formation of the cochlear neuron responses under the stimulation of the hearing system by a tone signal with a changing frequency and by a signal consisting of two tones. It is shown that the proposed model explains the effect of inhibition of the neuron response to a given tone signal when another tone signal of proper intensity arises in a definite frequency region.
