摘要:
我们提出了对 Rodrigues 等人(PNAS,2016)所提出神经递质释放模型的一种推广。通过采用四次多项式作为临界流形的参数化,我们提高了底层慢-快系统的复杂度。我们关注可能的瞬态与渐近动力学,利用所谓的 entry-exit 函数来描述动力学的慢变部分。我们提供了大量数值模拟,并辅以数值分岔分析。
英文摘要:
We propose a generalization of the neurotransmitter release model proposed in \emph{Rodrigues et al. (PNAS, 2016)}. We increase the complexity of the underlying slow-fast system by considering a degree-four polynomial as parametrization of the critical manifold. We focus on the possible transient and asymptotic dynamics, exploiting the so-called entry-exit function to describe slow parts of the dynamics. We provide extensive numerical simulations, complemented by numerical bifurcation analysis.
