Abstract
A model system for intracellular calcium oscillations was investigated when
the control parameter was perturbed by noise near a Hopf bifurcation point
. Noise-induced oscillations were observed. Furthermore, the output signal-
to-noise ratio (SNR) of the system went through a maximum with the incremen
t of noise intensity indicating the occurrence of internal stochastic reson
ance (SR), which showed the constructive role of noise at the cellular leve
