Abstract: Noise, is familiar from communications, where a single parameter such as voltage varies with time. Usually it is a nuisance, but sometimes, because of the peculiar phenomenon known as stochastic resonance, it is a boon, increasing signal strength. Noise is also present in many extended natural phenomena, such as calcium-ion waves in the brain. Are there also extended systems in which the noise can increase some collective, or coherent, dynamical property? Such spatiotemporal stochastic resonance has now been achieved experimentally for the first time.
