Stochastic resonance is a remarkable phenomenon that can enhance signal processing by the addition of random noise. However, the effect of magnetic fields on stochastic resonance under channel noises has been inadequately studied. In this paper, the stochastic resonance in Hodgkin-Huxley neuronal network under Gaussian channel noises and non-Gaussian channel noise were studied, and the effects of electromagnetic field stimulation on stochastic resonance were considered. The results indicate that stochastic resonance in neuronal networks can be induced by Gaussian channel noise and non-Gaussian Levy channel noise, and stochastic resonance may occur more easily under Levy channel noise. The resonance amplitude was significantly improved by selecting appropriate parameters of the magnetic field, while, a too strong magnetic field can be detrimental to the resonance amplitude. Magnetic fields may induce the enhancement of the resonance amplitude by increasing the firing frequency and spiking regularity.
随机共振是一种显著的现象,它可以通过添加随机噪声来增强信号处理。然而,磁场在信道噪声下对随机共振的影响尚未得到充分研究。本文研究了高斯信道噪声和非高斯信道噪声下霍奇金-赫胥黎神经网络中的随机共振,并考虑了电磁场刺激对随机共振的影响。结果表明,高斯信道噪声和非高斯列维信道噪声均可诱导神经网络中的随机共振,且在列维信道噪声下随机共振可能更容易发生。通过选择合适的磁场参数,共振幅度得到显著提高,而太强的磁场可能会对共振幅度产生不利影响。磁场可能通过增加放电频率和放电规律性来诱导共振幅度的增强。
