The membrane potential starts to integrate incoming currents again until it reaches the lower threshold V ( t h l o w ) V_{(th-low)} of -0.2 V. As the membrane potential gradually increases, the Schmitt trigger circuit detects the crossing of V ( t h l o w ) V_{(th-low)} of...
Voltage traces of the LIF neuron (Fig.7.4) don't have this feature. However, we can modify the LIF neuron to introduce an inflection point, as followsdoi:10.1007/978-3-319-51171-9_8Christoph BrgersSpringer International PublishingBo¨rgers, C. (2017). Quadratic integrate-and-fire (qif) ...
We calculate the firing rate of the quadratic integrate-and-fire neuron in response to a colored noise input current. Such an input current is a good approximation to the noise due to the random bombardment of spikes, with the correlation time of the noise corresponding to the decay time of...
The neural model used in simulations was developed to allow for an analytic solution to a neuron's fire time, while maintaining a non-instant post-synaptic potential rise time. The synaptic weights and delays were tuned using an evolution-strategy. Simulation experiments demonstrate that already ...
tage of this to test a range of synaptic time constants, and so broaden the validity of our conclusions. Although we focus on the quadratic integrate and fire neuron, our approach can be extended, at least in principle, to any single neu- ron model. However, in most cases–especially thos...
Originality/value The novel aspect of this paper is the application of the numerical methods to study the modified version of leaky integrate-and-fire neuron based on a QIF neuron. The model of the current study is inspired from the base model given in Stein (1965) and modified version in ...
Also, these neurons in the processor can be configured as novel models, integer quadratic integrate-and-fire neuron models, which contain an unsigned 8-bit membrane potential value. The processor can implement intelligent decision making for avoidance in real-time. Moreover, the proposed approach ...
Utilizing the equivalence of the quadratic integrate-and-fire and the theta-neuron formulations, we first derive the dynamical equations in terms of the ... B Pietras,R Cestnik,A Pikovsky - 《Physical Review E》 被引量: 0发表: 2023年 Designing spiking neural networks for robust and reconfigur...
We consider a large network of globally coupled quadratic integrate-and-fire neurons, which are canonical representatives for class I neurons near the spiking threshold. The model includes two heterogeneous parameters. One of them characterizes the state of isolated neurons and subdivides them into ...
We study the dynamics of a quadratic integrate-and-firemodel of a singlecompartment neuron with a slow recovery variable, as input current and parameters describing timescales, recovery variable, and postspike reset change. Analysis of a codimension 2 bifurcation reveals that the domain of attraction...
