神经元 HR 模型簇放电活动的计算机仿真

摘要

Ab stract: Four types of bursting pattern were simulated in the HR model. They are fold/SupHopf bursting via fold/fold hysteresis loop, SupHopf/SupHopf bursting via fold/fold hysteresis loop, fold/fold bursting via point-point hysteresis loop, and fold/homoclinic bursting via fold/homoclinc hysteresis loop. The dynamical behavior and mechanisms of them were also studied.%针对神经元 HR 模型，通过数值仿真，发现系统出现4种不同的转迁行为。运用快慢动力学理论，将这些神经元簇放电活动归结为4类不同的模式：fold/fold 滞后环 fold/SupHopf 型、fold/fold 滞后环 SupHopf/SupHopf 型、fold/fold 点-点滞后环型、fold/homoclinic 滞后环的 fold/homoclinic 型，并探讨它们的动力学行为和产生机制。
