Abstract: | By the intracellular calcium ionic minimal model proposed by Berridge, we investigated the collective response of two-dimensional
(N×N) coupled cell systems to the external stimulation using numerical simulation methods. With a coupled intensity fixed and
an appropriate coupled cell number chosen, the kinetic system size resonance was discovered. At the same time, it was found
that the system size responding to the external stimulation for different coupled intensities transferred too, especially
when the coupled intensity increased, the range of the corresponding system size extended. These phenomena illustrate that
the coupled cell number and the coupled intensity can play constructive roles in noisy coupled systems, by which the biology
system would probably improve its capability to respond to the external stimulation. |
