Abstract

The stochastic properties of the neural encoding mechanism of sound intensity were described. The homogeneous Poisson process was modified and extended to give a more realistic stochastic model that expressed the properties of auditory neurons quantitatively. A command program was written to control the different parameter values to study the effects of the different components on the mean-variance ratio. It was found that the ratio was a monotonic increasing function of dead time under a fixed firing rate, while it increased with increasing values of firing rate.
