我们数值研究了非高斯色噪声如何影响Hodgkin-Huxley神经元网络的空间相干性。从模拟结果中，我们发现存在着一定的中间噪声强度、色噪声的关联时间以及与高斯色噪声的偏离，使得系统以共振的方式出现具有系统特征空间频率的有序模式.即在一定条件下，非高斯色噪声可以优化所研究神经元网络的空间相干性，这表明空间相干共振的发生。
We numerically study how non-Gaussian colored noise affects the spatial coherence of a Hodgkin—Huxley neuronal network. From the simulation results, we find that there exists some intermediate noise intensities, correlation time of the colored noise, and the deviation from Gaussian colored noise, for which an ordered pattern with a characteristic spatial frequency of the system comes forth in a resonant manner. Namely, under certain conditions, spatial coherence of the studied neuronal network can be optimized by the non-Gaussian colored noise, which indicates the occurrence of spatial coherence resonance.
