Biological systems, particularly the neuronal system and cardiac tissue, can give complex dynamical responses when an external electromagnetic field is applied to the media. It is difficult to describe the effects of electromagnetic radiation on the neuronal system. Some researchers have claimed that additive transmembrane current and voltage can be applied to the neuron model. In fact, this description does not take into account the effects of physical electromagnetic induction, and thus we present a different conception from the original neuron model.

Indeed, the ion concentration in cells can be greatly changed and the media can be depolarized when an electromagnetic field is applied. It is believed that magnetic flux can describe the complex effects of time-varying electromagnetic fields according to the law of electromagnetic induction. As a result, magnetic flux can be used to detect the effect of an electromagnetic field by adding a new variable to a biological system like the neuron model. Furthermore, the induced current resulting from the change in electromagnetic field is mapped to modulate the membrane potential by using memristor coupled with magnetic flux.

The improved neuron model can describe the effect of electromagnetic induction, and the radiation effect can be calculated by adding external magnetic flux to the model. Of particular interest is the occurrence of multiple modes in electrical activities under electromagnetic radiation. Furthermore, we can also apply this to the cardiac tissue model; it is interesting as well to explore the death mechanism of a heart subjected to electromagnetic radiation.

This Research Topic is open to relevant approaches to be carried out in a neuron model setting, implementation of neuronal circuits, dynamical response of a network of neurons under electromagnetic radiation, collapse of neuronal network, pattern selection and control, and noise-induced mode selection.

Relevant submissions are considered as follows:

 1) Neuronal circuits under electromagnetic induction and radiation;
 2) Detection of multiple modes in electrical activities of isolated neurons under electromagnetic radiation and noise;
 3) Synchronization of neurons and neuronal networks under electromagnetic radiation;
 4) Pattern selection and control of neuronal systems exposed to electromagnetic radiation;
 5) Heart and brain disease induced by electromagnetic radiation;
 6) Other relevant approaches to this issue.


Keywords: electromagnetic radiation, noise, neuron, synchronization stability
