摘要 运用数值模拟方法,研究了由两个完全相同的Hindmarsh-Rose神经元通过单向延迟反馈耦合连接组成系统的动力学行为.研究结果表明,当延迟时间和耦合强度在适当的范围内取值时,从动神经元发生放电活动时所产生的动作电位,能够预测主动神经元发生放电活动时所产生的动作电位,即出现了预测同步现象. Dynamic behaviors of two identical Hindmarsh-Rose neurons with unidirectional timedelay feedback coupling were numerically studied. The results showed that the action potentials fired by the slave system could anticipate the action potentials fired by the drive system under appropriate delay time and coupling strength, which indicating the occurrence of anticipating synchronization.
