Fano factor: a potentially useful information

K Rajdl, P Lansky, L Kostal - Frontiers in computational neuroscience, 2020 - frontiersin.org
The Fano factor, defined as the variance-to-mean ratio of spike counts in a time window, is
often used to measure the variability of neuronal spike trains. However, despite its …

Stimulus presentation can enhance spiking irregularity across subcortical and cortical regions

S Fayaz, MA Fakharian… - PLoS Computational …, 2022 - journals.plos.org
Stimulus presentation is believed to quench neural response variability as measured by
fano-factor (FF). However, the relative contributions of within-trial spike irregularity and trial …

Statistics of inverse interspike intervals: The instantaneous firing rate revisited

L Kostal, P Lansky, M Stiber - Chaos: An Interdisciplinary Journal of …, 2018 - pubs.aip.org
The electric discharge activity of neurons is composed of stereotyped events called action
potentials or spikes. The exact timing of spikes under identical external conditions may vary …

[HTML][HTML] Entropy factor for randomness quantification in neuronal data

K Rajdl, P Lansky, L Kostal - Neural Networks, 2017 - Elsevier
A novel measure of neural spike train randomness, an entropy factor, is proposed. It is
based on the Shannon entropy of the number of spikes in a time window and can be seen …

Signal-to-noise ratio gain of an adaptive neuron model with Gamma renewal synaptic input

Y Kang, Y Fu, Y Chen - Acta Mechanica Sinica, 2022 - Springer
We take an adaptive leaky integrate-and-fire neuron model to explore the effect of non-
Poisson neurotransmitter on stochastic resonance and its signal-to-noise ratio (SNR) gain …

Strongly super-Poisson statistics replaced by a wide-pulse Poisson process: the billiard random generator

OA Chichigina, D Valenti - Chaos, Solitons & Fractals, 2021 - Elsevier
In this paper we present a study on random processes consisting of delta pulses
characterized by strongly super-Poisson statistics and calculate its spectral density. We …

Integrated random pulse process with positive and negative periodicity

AV Kargovsky, OA Chichigina - Physical Review E, 2022 - APS
A study of nonstationary processes that are integrals of stationary random sequences of
delta pulses is presented. An integrated renewal process can be represented as the sum of …

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

O Shchur, A Vidybida - Fluctuation and Noise Letters, 2023 - World Scientific
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 …

NeuroVI-based new datasets and space attention network for the recognition and falling detection of delivery packages

X Liu, ZX Yang, Z Xu, X Yan - Frontiers in Neurorobotics, 2022 - frontiersin.org
With the popularity of online-shopping, more and more delivery packages have led to
stacking at sorting centers. Robotic detection can improve sorting efficiency. Standard …

A Convex Formulation of Point Process Heartbeat Dynamics using a Gamma Generalized Linear Model

A Perley, S Subramanian… - 2023 IEEE 19th …, 2023 - ieeexplore.ieee.org
Heartbeat dynamics have been long studied in understanding the cardiovascular and
autonomic nervous systems. Traditional methods use windowed time averaging in order to …
