The effects of nonlocal and fractal connectivity are investigated in a network of Leaky Integrate-and-Fire (LIF) elements. The idea of fractal coupling originates from the hierarchical topology of networks formed by neuronal axons, which transmit the electrical signals in the brain. If a number ...

该储备池有大量的LIF ( Leaky Integrate and Fire )神经元,这些神经元通过动态突触连接与生物现实参数循环地相互连接。读出也是由几个LIF神经元实现的,但是它们之间没有任何互连。液体将低维的输入流转化为高维的内部状态,作为无记忆读出电路的输入,负责产生LSM的最终输出。( Maass et al 2002)。图1描绘了LSM的典...

It is shown that the Leaky integrate-and-fire (LIF) model of a neuron has a poor selectivity to its preferred pattern. Its response is determined by the total current injected by input spike trains. Thus, a few inputs with a high activity (an incomplete pattern) can elicit the same ...
Leaky integrate-and-fire (LIF) networks are often used to model neural network activity. The spike trains they produce, however, cannot be directly compared to the local field potentials (LFPs) that are measured by low-pass filtering the potential recorded from extracellular electrodes. This is ...

We compute the firing rate of a leaky integrate-and-fire (LIF) neuron with stochastic conductance-based inputs in the limit when synaptic decay times are much shorter than the membrane time constant. A comparison of our analytical result... TD Oleskiw,W Bair,E Shea-Brown,... 被引量: 0...
We consider the arguably most prominent model for spiking neurons in the brain: leaky integrate-and-fire (LIF) neurons, where spikes that arrive from other neurons through synaptic connections are multiplied with the corresponding synaptic weight, and are linearly integrated by a leaky membrane ...
