Stochastic resonance and the benefits of noise: from ice ages to crayfish and SQUIDs

Nature. 1995 Jan 5;373(6509):33-6. doi: 10.1038/373033a0.


Noise in dynamical systems is usually considered a nuisance. But in certain nonlinear systems, including electronic circuits and biological sensory apparatus, the presence of noise can in fact enhance the detection of weak signals. This phenomenon, called stochastic resonance, may find useful application in physical, technological and biomedical contexts.
