Power-law statistics and universal scaling in the absence of criticality

J Touboul, A Destexhe - Physical Review E, 2017 - APS
Critical states are sometimes identified experimentally through power-law statistics or
universal scaling functions. We show here that such features naturally emerge from …

Republished: Dynamics of stochastic integrate-and-fire networks

GK Ocker - Physical Review X, 2023 - APS
The neural dynamics generating sensory, motor, and cognitive functions are commonly

Exact analysis of the subthreshold variability for conductance-based neuronal models with synchronous synaptic inputs

LA Becker, B Li, NJ Priebe, E Seidemann… - Physical Review X, 2024 - APS
The spiking activity of neocortical neurons exhibits a striking level of variability, even when
these networks are driven by identical stimuli. The approximately Poisson firing of neurons …

Metastability for systems of interacting neurons

E Löcherbach, P Monmarché - Annales de l'Institut Henri Poincare …, 2022 - projecteuclid.org
We study a stochastic system of interacting neurons and its metastable properties. The
system consists of N neurons, each spiking randomly with rate depending on its membrane …

Stochastic models of neural synaptic plasticity

P Robert, G Vignoud - SIAM Journal on Applied Mathematics, 2021 - SIAM
In neuroscience, learning and memory are usually associated with long-term changes in
neuronal connectivity. In this context, synaptic plasticity refers to the set of mechanisms …
