The integrate and fire model is a single compartment model which is useful for understanding how an ensemble of neurons, neighboring neurons which group together and fire together, interact and sum large number of synaptic inputs. When a threshold value of the membrane potential of a neuron is ...
4) neuron model 神经元模型 1. In this paper,the responses of FitzHugh-Nagumo(FN) neuron model,which is stimulated by additive Gaussian white noise and weak sinusoidal signal,is investigated via numerical simulations. 8时模型的输出信噪比最大,表明该神经元模型有频率敏感性,即更易于检测到该范围内...

The integrate-and-fire neuron model describes the state of a neuron in terms of its membrane potential, which is determined by the synaptic inputs and the
内容提示: Integrate-and-Fire Neurons and Networks∗Wulfram GerstnerEPFL, Laboratory of Computational Neuroscience, CH-1015 Lausanne EPFLIntroductionMost biological neurons communicate by short electrical pulses, called ac-tion potentials or spikes. In contrast to the standard neuron model used in...
We identify the non-linear I-V characteristics and the gate of the SCR as the key features which enable a simple implementation of an electronic neuron with the leaky-integrate-and-fire (LIF) model functionality8. The Ultra-Compact Leaky-Integrate-and-Fire Neuron Model The circuit of our ...
We compute the VC dimension of a leaky integrate-and-fire neuron model. The VC dimension quantifies the ability of a function class to partition an input pattern space, and can be considered a measure of computational capacity. In this case, the function class is the class of integrate-and...
