Regulating memristive neuronal dynamical properties via excitatory or inhibitory magnetic field coupling

The ion exchange in neurons can trigger time-varying magnetic fields. According to the superposition field principle, each neuron is exposed to the integrated magnetic field generated by the other neurons. This paper considers the effect of magnetic field coupling between two neurons on neuron dynamics. The magnetic flux of the memristor describes the impact of the magnetic field. According to the different coupling types of neurons, the excitatory coupling between excitatory neurons. The inhibitory magnetic coupling between excitatory and inhibitory neurons is also considered. And then, the excitatory and inhibitory magnetic field coupling is studied under different external excitation currents. The excitatory magnetic field coupling can promote the firing of neurons. When the intensity of inhibitory magnetic field coupling is large enough, the neuronal firing mode is static. The firing mode of neurons can be changed by adjusting the coupling intensity. Therefore, magnetic field coupling can provide new insights into the mechanism of information interaction between neurons. Finally, the excitability and inhibition of magnetic field coupling are improved by comparing magnetic field coupling with synaptic coupling. These results indicate that magnetic field coupling has the same function as a synapse to some extent and has the characteristics of radiation propagation.
