Abstract
We have investigated information transmission in an array of threshold units. Each unit receives a common input signal but independent multiplicative noise. We demonstrate a phenomenon similar to stochastic resonance and suprathreshold stochastic resonance 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 benefitial in increasing information transmission in neural populations.
