Abstract
Systems of coupled oscillators are used as models of collective or cooperative behaviour in many diverse areas of science, from physics to neuroscience and biology. It is well known that these systems can display both disordered, non-synchronous behaviour, where each oscillator behaves essentially independently, and ordered, synchronous behaviour, where either the phases or frequencies of the oscillators can lock together and the ensemble of oscillators behaves in a coherent, ordered manner. The effect of noise in nonlinear dynamical systems has been the subject of much recent interest. It has been shown that, counterintuitively, under certain conditions it is possible for noise to enhance the coherent response of the system.
