  • The effect of random long-range connections(shortcuts)on Ca2 + signal propagation in the coupled cell chain is investigated by using the Euler method. It is found when the first cell is subjected to the external stimuli,the firing activity is triggered and then its neighboring cells excited,then the Ca2 + signal may propagate along the chain helped by the shortcuts,indicating the shortcuts can enhance intercellular Ca2 + signal propagations significantly. In addition,it is also found that there is an optimal level of randomness where the shortcuts can enhance the regularity of Ca2 + oscillations in the whole system. These results suggest that shortcuts among the cells may play a constructive role in helping the cell information propagating.

Abstract: The effect of random long-range connections(shortcuts)on Ca2 + signal propagation in the coupled cell chain is investigated by using the Euler method. It is found when the first cell is subjected to the external stimuli,the firing activity is triggered and then its neighboring cells excited,then the Ca2 + signal may propagate along the chain helped by the shortcuts,indicating the shortcuts can enhance intercellular Ca2 + signal propagations significantly. In addition,it is also found that there is an optimal level of randomness where the shortcuts can enhance the regularity of Ca2 + oscillations in the whole system. These results suggest that shortcuts among the cells may play a constructive role in helping the cell information propagating.
