脉冲耦合神经元网络张开状态的稳定性

Stability of the splay state in networks of pulse-coupled neurons

Simona Olmi, Antonio Politi, Alessandro Torcini

摘要:

我们分析研究了神经元的$N$脉冲耦合类相位模型网络中{ \it splay态}的稳定性。通过发展微扰技术,我们发现,在大的$N$的限制,Floquet谱尺度为$1/N^2$一般的不连续速度场。此外,所谓的短波长分量的稳定性由不连续处的跳跃的符号决定。总之,频谱的形式取决于脉冲的形状,但与速度场无关。

英文摘要:

We analytically investigate the stability of {\it splay states} in networks of $N$ pulse-coupled phase-like models of neurons. By developing a perturbative technique, we find that, in the limit of large $N$, the Floquet spectrum scales as $1/N^2$ for generic discontinuous velocity fields. Moreover, the stability of the so-called short-wavelength component is determined by the sign of the jump at the discontinuity. Altogether, the form of the spectrum depends on the pulse shape but is independent of the velocity field.
