Regulating Neuronal Excitation or Inhibition Via Magnetic Field Coupling

Abstract

The ion exchange in neurons can trigger time-varying magnetic fields that interact with each other. In this work, the regulation of neuronal excitation and inhibition by coupling magnetic field is investigated. Firstly, models of magnetic field coupling under different conditions are proposed. The effect of the magnetic field is described by magnetic flux. And then, the excitation or inhibition magnetic field coupling is studied under different external excitation currents. The firing mode of neurons can be changed by adjusting the coupling intensity.  In brief, we found that the magnetic field coupling can regulate the excitation and inhibition of neurons, and the excitation magnetic field coupling can promote the firing of neurons. When the inhibition magnetic field coupling is large enough, the neuronal firing mode is static. Magnetic field coupling can be considered as a way to modulate the neuronal excitation. In the end, the magnetic coupling and synaptic coupling equations are compared and the effects of modulation of magnetic field coupling on neuronal excitation and inhibition are investigated. Studying the magnetic field coupling of neurons is important for understanding how neurons transmit information.
