Distribution of interspike intervals of a neuron with inhibitory autapse stimulated with a renewal process

Autor: Shchur, Olha, Vidybida, Alexander

In this paper, we study analytically the impact of an inhibitory autapse on neuronal activity. In order to do this, we formulate conditions on a set of non-adaptive spiking neuron models with delayed feedback inhibition, instead of considering a part

Autor: Vidybida, Alexander, Shchur, Olha

Publikováno v: Vidybida, A., & Shchur, O. (2021). Moment-Generating Function of Output Stream of Leaky Integrate-and-Fire Neuron. Ukrainian Journal of Physics, 66(3), 254

The statistics of the output activity of a neuron during its stimulation by the stream of input impulses that forms the stochastic Poisson process is studied. The leaky integrate-and-fire neuron is considered as a neuron model. A new representation o

First passage time distribution for spiking neuron with delayed excitatory feedback

Autor: Shchur, Olha, Vidybida, Alexander

Publikováno v: Fluctuation and Noise Letters, Vol. 19, No. 01, 2050005 (2020)

A class of spiking neuronal models with threshold 2 is considered. It is defined by a set of conditions typical for basic threshold-type models, such as the leaky integrate-and-fire (LIF) or the binding neuron model and also for some artificial neuro

Relation between firing statistics of spiking neuron with delayed fast inhibitory feedback and without feedback

Autor: Vidybida, Alexander, Shchur, Olha

Publikováno v: Fluctuation and Noise Letters, Vol. 17, No. 01, 1850005 (2018)

We consider a class of spiking neuronal models, defined by a set of conditions typical for basic threshold-type models, such as the leaky integrate-and-fire or the binding neuron model and also for some artificial neurons. A neuron is fed with a Pois
