Stochastic Resonance: Past progress and open questions

Kurt Wiesenfeld,

In systems displaying stochastic resonance (SR), the addition of random noise results in more regular output behavior. The phenomenon is readily seen and well understood in a wide variety of physical examples. More recently, efforts have intensified to explore the role of SR in biological settings. I'll describe some of these efforts, and how they have opened up new questions for the fundamental theory.
