We investigated whether the LIF model with receptor dynamics (2.1)– (2.5) can reproduce the average response of ORNs to a pheromone pulse stimulus ( figure 1 c – f ).
WebIntegrate-and-Fire Neuron 图1：神经元的放电模型 动作电位非常重要，但是其持续时间很短，在神经活动的总时长中占比很少。 神经元在大部分的时间，都是在对输入信号进行运算处理。 动作电位的波形都是十分相似的，无法提供足够的有效信息。 那么我们这里提供了一个简单的放电模型（图1）：膜电位对输入的信号进行线性叠加，如果膜电位超过了阈值 … WebNov 15, 2008 · This firing pattern is the only firing pattern that a standard leaky or non-leaky integrate-and-fire model can generate subject to constant current injection. In the framework of the AdEx, it corresponds to the absence of spike-triggered adaptation and adaptation sensitivity to subthreshold voltage (a, b = 0). Most neurons, however, show …
