Stochastic Resonance and Stochastic Encoding: Cooperative Effects of Noise and Intrinsic Dynamics in a Model Neuron with Subthreshold Oscillations

摘要：

It is well established that noise, despite its mostly detrimental effects, can play a constructive role for information transfer. The best known example is stochastic resonance (SR) phenomena. SR means that there is an optimal level of noise for the detection of weak signals. In this study, a Hodgkin-Huxley type model neuron with subthreshold oscillations has been used to demonstrate that the noise effects essentially depend on the neurons activity state. These data shall emphasize more general aspects of stochastic encoding (SE) which, beyond tuning of noise, can be achieved with appropriate adjustment of physiological control parameters.
