White noise-induced spiral waves and multiple spatial coherence resonances in a neuronal network with type I excitability

► A network composed of neurons with type I excitability and large initial values. ► White noise can induce wave patterns and multiple resonances in the network. ► A possible physical mechanism to understand the multiple resonances is provided. ► Dynamics of type I excitability and initial values are key to the above mechanism. ► A relationship of the simulation to the experimental spiral waves is discussed.
