| 摘 要： | 在二维映射神经元模型中,同时施加高、低两种不同频率的刺激信号,以高频信号为调制信号,研究其对系统动力学特性的影响.仿真结果表明,通过调节高频信号的幅值为某一合适值,可以使得神经元膜电位对弱低频信号的线性响应达到最优,产生振动共振现象, 从而证实了高频刺激信号能够帮助神经元探测和传导弱低频信号.另外,还研究了模型和信号参数对系统共振特性的影响.

| Abstract: | The dynamics of a two-dimensional neural map subjected to two harmonic signals with different frequencies was investigated by numerical simulation. The linear response of neuron membrane potential to the low-frequency signal can achieve optimal by modulating the amplitude of high-frequency signal to an appropriate value,where the phenomenon of vibrational resonance occurs. It is shown that the high-frequency signal can help the weak low-frequency signal detection and information propagation. Furthermore,the influences of parameters of the map and input signals on the resonance dynamics were also studied. |
