Towards Simplicity: Noise and Cooperation in the Perfect Integrator

Abstract

Neuroscientists have known for decades that sensory information is encoded in the intervals between the action potentials or spikes characterizing neural firing event-,-. Statistical analyses of experimentally obtained spike trains have shown the existence of a significant random component in the inter- spike intervals. There has been speculation, of late, that the noise may actually facilitate the transmission of sensory information; certainly there exists evidence that noise in networks of neurons can dynamically alter the properties of the membrane potential and the time constants 37,66. This paper describes the recent rekindling of interest in the Stochastic Resonance phenomenon leading to speculation that such nonlinear cooperative effects may occur naturally in living systems.
