神经元HR模型簇放电活动的计算机仿真

Computer simulation of neuron bursting in HR model

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。

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.
