摘要
We investigate responses of a model for intracellular Ca2+ oscillations to external pulsatile forcing in the presence of additive Gaussian noise. Our results show that noise makes the system less susceptible to external forcing and thus enhances robustness of Ca2+ oscillations. The results can be well explained by the local divergence of limit cycles in the phase space. (C) 2003 Elsevier B.V. All rights reserved.
