title: Stochastic resonance in the brusselator model
abstract: Using the Brusselator model, we show that in a simple dynamical system small noise can be converted into stochastic spikewise oscillations of huge amplitude (bursting noises) in the vicinity of a Hopf bifurcation. Small periodic signals with amplitude several times less than the noise intensity transform these stochastic oscillations into quasiperiodic large-amplitude spikewise oscillations or small-amplitude quasiharmonic oscillations, depending on the signal form.
