Model of discharge patterns of units in the cochlear nucleus in response to steady state and time-varying sounds

摘要

A model for the coding of sounds in the discharge pattern of single neurons in the auditory periphery is described. The model consists of a non-linear differential equation and a conventional diffusion neuron model. The same model describes 1) the unit interspike interval distribution in response to continuous stimulation, 2) the response to tone bursts, as well as 3) the responses to sinusoidally amplitude-modulated stimuli. The parameters of the model are determined quantitatively for each neuron. The responses of a certain unit can be described by 5 parameters.
