Noise and Periodic Modulations in Neural Excitable Media
arXiv:cond-mat/9801261 · doi:10.1103/PhysRevE.59.5920
Abstract
We have analyzed the interplay between noise and periodic modulations in a mean field model of a neural excitable medium. To this purpose, we have considered two types of modulations; namely, variations of the resistance and oscillations of the threshold. In both cases, stochastic resonance is present, irrespective of if the system is monostable or bistable.
