离子通道的电压门控特性靠设定一个threshold来实现,除此之外,LIF模型还考虑了动作电位之后的不应期: 在发放了一个动作电位之后: 神经元会位置在一个reset电位几毫秒。 LIF模型的公式 LIF模型的数学阐述如下: 主要是通过这个公式来描述膜电位的被动特性以及外部输入电流的影响。 C_m\frac{dV}{dt} = -G_L(V - ...
LIF模型,顾名思义,包含了以下三大特征: Leaky:存在欧姆漏电流。 Integrate:一个能积累电流的部件,电容。 Fire:当输入电流足够大的时候,膜电压会产生突变(spiking) 它的线性微分方程表达式如下: CdVmdt=I−gleak(Vm−Eleak) 由方程易得LIF模型有这样的性质 存在明确的临界电压Vthresh,当电压大于等于这个值的时...
