Abstract: An intracellular calcium oscillation (ICO) system with non-Gaussian noises in transmission processes of intracellular Ca2+ is studied by means of a second-order stochastic Runge–Kutta type algorithm. The normalized autocorrelation function (NAF) and the characteristic correlation time (CCT) of cytosolic and calcium store’s Ca2+ concentration are simulated. The results exhibit that both NAFs of cytosolic and calcium store’s Ca2+ concentration show almost periodic oscillation when the non-Gaussian noises are weak or the correlation time of non-Gaussian noises is long, but the oscillations of both NAFs decrease when the non-Gaussian noises are strong or the correlation time is short. Moreover, both CCTs of cytosolic and calcium store’s Ca2+ concentration demonstrate that noises enhance stability, reverse resonance, and coherence resonance occur in the ICO system.
