TL;DR
This paper investigates how high-frequency signals influence the FitzHugh-Nagumo neuron model, revealing suppression of firing activity and the emergence of vibrational resonance at certain noise levels.
Contribution
It provides new insights into the effects of high-frequency signals on neuronal excitability and demonstrates vibrational resonance phenomena in the model.
Findings
Firing rate decreases with increasing high-frequency amplitude-to-frequency ratio.
Excitable behavior is suppressed above a certain ratio threshold.
Vibrational resonance appears at high noise strengths.
Abstract
The effect of a high-frequency signal on the FitzHugh-Nagumo excitable model is analyzed. We show that the firing rate is diminished as the ratio of the high-frequency amplitude to its frequency is increased. Moreover, it is demonstrated that the excitable character of the system, and consequently the firing activity, is suppressed for ratios above a given threshold value. In addition, we show that the vibrational resonance phenomenon turns up for sufficiently large noise strength values.
