The spatiotemporal patterns of HodgkinHuxley neuronal networks induced by external gauss noise and channel gauss noise were investigated. And the dynamic behaviors of HodgkinHuxley neuronal networks under different noise were compared. It is found that the channel gauss noise is more conducive to the transformation of spatiotemporal patterns and the formation of spiral wave in neuronal network. Finally, the effect of temperatures and coupling coefficients on spatiotemporal dynamics of neural network was further analyzed.
