时滞耦合可兴奋神经系统的动力学

Dynamics of delay-coupled excitable neural systems

M. A. Dahlem, G. Hiller, A. Panchuk, E. Schoell

摘要:

我们研究了两个时滞耦合神经系统的非线性动力学,每个系统由FitzHugh-Nagumo型的可激发动力学建模,并证明了在足够大的延迟时间和耦合强度下,稳定不动点和极限环振荡之间的双稳态。作为这些延迟引起的振荡的机制,我们确定了极限环的鞍结分岔。

英文摘要:

We study the nonlinear dynamics of two delay-coupled neural systems each modelled by excitable dynamics of FitzHugh-Nagumo type and demonstrate that bistability between the stable fixed point and limit cycle oscillations occurs for sufficiently large delay times and coupling strength. As the mechanism for these delay-induced oscillations we identify a saddle-node bifurcation of limit cycles.
