Paper Abstract

We have investigated information transmission in an array of threshold units with multiplicative noise that have a common input signal. We demonstrate a phenomenon similar to stochastic resonance with additive noise, and show that information transmission can be enhanced by a non-zero multiplicative noise level. Given that sensory neurons in the nervous system have multiplicative as well as additive noise sources, and they act approximately like threshold units, our results suggest that multiplicative noise might be an essential part of neural coding.
