We consider system of globally coupled FitzHugh-Nagumo (FHN) models; each element is subjected to a subthreshold periodic signal and independent Gaussian white noise. With the variation of the system size, the spike train of the mean field of the system fires according to the period of the subthreshold external signal or to the interior time scale of the FHN model. The influence of the coupling strength is also investigated. It only influences the response of the mean field to external signal. If two external signals are injected to the system simultaneously, the least-common-multiple periods or other common multiples may be selected by different system sizes.
我们考虑全局耦合的FitzHugh-Nagumo（FHN）模型系统；每个元件都受到阈下周期信号和独立高斯白噪声的作用。随着系统规模的变化，系统平均场的脉冲序列根据阈下外部信号的周期或FHN模型的内部时间尺度触发。我们还研究了耦合强度的影响。它仅影响平均场对外部信号的响应。如果同时向系统注入两个外部信号，不同的系统规模可能会选择最小公倍数周期或其他公倍数周期。
