[Model of representation of the phage structure of a 2-tone stimulus in the impulses of the neurons of the cochlear nucleus].

A model of the representation of information about the phase structure of oscillations in bitonal stimuli at the level of the neurons in cochlear neucleus is described. It is shown that for an agreement with the experimental results the degree of excitation of the final neuron of the model has to be proportional to the absolute value of the difference between the excitations coming to it from different groups of auditory nerve fibres. It is supposed that the sensitivity of neurons' response to the phase relations between the oscillations from which the stimulus consists could be due to possible dependence of the degree of receptor excitation either on bending or the hear cells or on the change of the sound pressure level in endolimphe.
