Effects of electromagnetic induction on vibrational resonance in fast spiking Izhikevich neuronal systems

In this paper, the vibrational resonance (VR) properties of single and bidirectionally coupled fast spiking Izhikevich neuron systems under varying electromagnetic induction (EMI) conditions are systematically investigated using an improved Izhikevich neuron model. It is found that in the absence of EMI, multiple vibrational resonances (MVR) phenomena can be observed in the single neuron model. However, the introduction of EMI significantly weakens the VR effect, with this attenuation being more pronounced in the single neuron model. In the bidirectionally coupled neuron system, MVR phenomena disappear, and the coupling strength exerts a modulatory effect on vibrational resonance. Additionally, the study explored the effects of EMI parameters and coupling strength on Fourier coefficients. These findings suggest that EMI can diminish the signal detection capabilities of fast spiking neurons, with implications for understanding neural dynamics and advancing neuromodulation strategies for the management of neurological disorders.
