We examine the effects of stochastic input currents on the firing behaviour of two coupled Type 1 or Type 2 neurons. In Hodgkin-Huxley model neurons with standard parameters, which are Type 2, in the bistable regime, synaptic transmission can initiate oscillatory joint spiking, but white noise can terminate it. In Type 1 cells (models), typified by a quadratic integrate and fire model, synaptic coupling can cause oscillatory behaviour in excitatory cells, but Gaussian white noise can again terminate it. We locally determine an approximate basin of attraction, [see text] of the periodic orbit and explain the firing behaviour in terms of the effects of noise on the probability of escape of trajectories from [see text].

一对耦合神经元中尖峰活动的随机扰动。

我们研究了随机输入电流对两个耦合的 1 型或 2 型神经元的放电行为的影响。在具有标准参数的 Hodgkin-Huxley 模型神经元中，即类型 2，在双稳态机制中，突触传递可以启动振荡关节尖峰，但白噪声可以终止它。在以二次积分和激发模型为代表的 1 类细胞（模型）中，突触耦合会导致兴奋性细胞的振荡行为，但高斯白噪声可以再次终止它。我们在本地确定了一个近似的吸引力盆地，[参见文本] 周期轨道，并根据噪声对 [参见文本] 中轨迹逃逸概率的影响来解释发射行为。
