Stochastic resonance refers to the enhancement of a signal by the addition of a small amount of noise and its degradation by a larger amount of noise. It occurs in a variety of physical systems including neuronal systems. However, its demonstration in neuronal systems has so far been limited to single-dimensional systems such as a single mechanoreceptor. We report here the existence of stochastic resonance in the visually evoked potential, a very high-dimensional neuronal system.
