Poisson spike-train
WebApr 12, 2024 · The network contains two populations of spiking neurons: 300 excitatory (E) cells and 100 inhibitory (I) cells. All neurons are driven by independent, identically distributed Poisson spike trains. The strength of the Poisson input maintains a physiologically realistic firing rate for each neuron. WebSep 15, 2024 · A Poisson process-based spike train is input into the perturbation neuron, which causes the neuron to generate noisy spike trains. Implemented within the program, the calculation can be simplified, and the probability that the spike is issued within the time step ∆t can be considered as \(r\Delta t\) , where \(r\) is the firing rate and …
