Abstract

In view of same time delay τ in active and passive transmission processes with colored noises of intracellular Ca2+, by means of second-order algorithm for stochastic simulation colored noises, the normalized autocorrelation function (NAF) and the characteristic correlation time (CCT) of cytosolic and calcium store’s Ca2+ concentration are studied. For the case of long τ: both NAFs of cytosolic and calcium store’s Ca2+ concentration exhibit periodically synchronous sawtooth wave, which linearly weakens as correlation time of colored noises or autocorrelation time increases. As τ increases, time delay induces oscillatory coherence in intracellular calcium oscillation system.
