摘要
采用数值仿真的方法,研究了电突触耦合对Hindmarsh-Rose(HR)神经元网络抗脉冲干扰特性的影响.结果表明:规则的耦合形式和神经元数目对网络的抗脉冲干扰特性影响较小;神经元间电突触耦合强度的分布对网络的抗脉冲干扰特性影响较大.在全局耦合结构下,当突触耦合强的度分布满足一定条件时,网络中的神经元仍能同步放电且保持稳定的放电频率,呈现出较好的抵御脉冲干扰能力.
The effect of electrical synapse on characteristic of anti-interference of identical HindmarshRose network was investigated with the method of numerical simulation.The simulation results show that the regular coupling and neuron mumber have small impact on characteristic of anti-interference. In contrast,the distribution of coupling intensity dominates the characteristic of anti-interference. The all-to-all network shows better capability to resist pulsed interference when the distribution is consonant with certain conditions.The neurons in network can still be synchronized and keep a stable firing rate as the pulsed interference occurred.
