A novel chaotic spiking neuron and its paralleled spike encoding function

摘要

Inspired by sound encoding mechanisms of the spiral ganglion cell in the mammalian inner ear, in this paper we present a novel chaotic spiking neuron and analyze its encoding function. A set of N neurons accepts a common analog input and outputs a set of N chaotic spike-trains. We give some theorems which guarantee that the set of neurons can encode various inputs (which can be constant, periodic, non-periodic or random) into a summation of their spike-trains in such a way that a spike density of the summed spike-train mimics a waveform of the input. We also confirm the encoding function of an electrical circuit model of the neuron by a SPICE simulation.
