Abstract: A two-dimensional neuronal network with unidirectional coupling is constructed, and information transmission entropy is introduced to describe the directed information transmission. Hindmarsh-Rose neuron model is used to study mechanism of spontaneous generation of ordered waves such as spiral waves in the network. Numerical simulation shows that the network can appear spontaneously spiral wave, traveling wave, target wave and plane wave with appropriately selected strength of coupling and distance of unidirectional coupling. It is found that generation of various ordered waves is related to intermittently directed information transmission in the network. Entropy resonance occurs as single or multiple spiral waves appear in the network. Intermittently directed information transmission is also observed in the network with noise, inhibitory coupling and repulsive coupling when spiral wave and multiple spiral waves are spontaneously appeared. Self-sustaining long plane waves are observed for the first time. It is due to persistent strong directed information transmission in the network.

Key words: Hindmarsh-Rose neuron, unidirectional coupling, spiral wave, information transmission entropy
