神经元的交流,传输与活动,都离不开一个个非常短暂的脉冲-Spike。有各种各样的模型,可以描述神经元的电位变化,发放,比如HH模型等等。但是如果只考虑比较粗糙的一些性质,比如膜电位的简单变化和spike的频率之…
leaky integrate-and-fireneuron modelsrefractory periodWe study the dynamics of identical leaky integrate-and-fire neurons with symmetric non-local coupling. Upon varying control parameters (coupling strength, coupling range, refractory period) we investigate the system's behaviour and highlight the ...
Leaky Integrate-and-Fire 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 Vthr...
However, the commonly used Leaky Integrate-and-Fire (LIF) model overlooks neuron heterogeneity and independently processes spatial and temporal information, limiting the expressive power of SNNs. In this paper, we propose the Dual Adaptive Leaky Integrate-and-Fire (DA-LIF) model, which introduces ...
progressing to more generalized leaky integrate-and-fire models. In the standard LIF model (GLIF1here), current injected into the cell causes the voltage to rise in a linear fashion. When the voltage reaches a fixed threshold (referred to as Θ∞here) the model spikes and the threshold is ...
We introduce an ultra-compact electronic circuit that realizes the leaky-integrate-and-fire model of artificial neurons. Our circuit has only three active devices, two transistors and a silicon controlled rectifier (SCR). We demonstrate the implementatio

Analysis of sinusoidal noisy leaky integrate-and-fire models and comparison with experimental data are important to understand the neural code and neural synchronization and rhythms. In this paper, we propose two methods to estimate input parameters usin
白话脉冲神经网络（3）：理解LIF（Leaky Integrate and Fire）神经元模型 神经元模型的世界多种多样，从复杂的生物模型到简单的数学抽象。LIF神经元，介于生物物理与人工神经元之间，以其平衡的生物合理性与计算效率吸引着研究者。它像人工神经元一样，通过加权输入，但不是直接激活，而是通过时间积分与泄漏...
