- Abstract
In this paper, to investigate the effects of electromagnetic radiation (ER) on synchronous dynamic behavior among different regions of the neural system, an indirect coupled network is constructed with several HR neuron sub-networks, in which N sub-networks are coupled with a central sub-network through a cell, respectively. The parameters of chemical synaptic coupling and ER variables were considered as regulatory parameters. It is found that, on the one hand, without the ER, appropriate chemical synaptic coupling could induce abundant discharge modes among indirect coupled network, such as chaos, chimera state and burst synchronous state. On the other hand, when the internal electromagnetic fields are considered, the weak electromagnetic fields from the charge movement in the cell membrane channel of neurons can effectively regulate the collective behavior among sub-networks: Positive feedback could enhance the synchronous behavior, while negative feedback may suppress it. Furthermore, the effect of ER from the outside of the system was also discussed. It is found that the intensity and frequency of external ER could effectively regulate the dynamic behavior of the neural network. Our results may have some theoretical significance for further understanding the intrinsic mechanisms of neurological diseases such as epilepsy and schizophrenia.
