Dynamics of a large system of spiking neurons with synaptic delay

F Devalle, E Montbrió, D Pazó - Physical Review E, 2018 - APS
We analyze a large system of heterogeneous quadratic integrate-and-fire (QIF) neurons with
time delayed, all-to-all synaptic coupling. The model is exactly reduced to a system of firing …

Local and global Hopf bifurcation analysis on simplified bidirectional associative memory neural networks with multiple delays

C Xu - Mathematics and Computers in Simulation, 2018 - Elsevier
In this paper, a class of simplified bidirectional associative memory (BAM) neural networks
with multiple delays are considered. By analyzing the associated characteristic …

[HTML][HTML] Standing and travelling waves in a spherical brain model: the Nunez model revisited

S Visser, R Nicks, O Faugeras, S Coombes - Physica D: Nonlinear …, 2017 - Elsevier
The Nunez model for the generation of electroencephalogram (EEG) signals is naturally
described as a neural field model on a sphere with space-dependent delays. For simplicity …

Relaxation oscillations and the mechanism in a periodically excited vector field with pitchfork–Hopf bifurcation

Y Xia, Z Zhang, Q Bi - Nonlinear Dynamics, 2020 - Springer
The traditional geometric singular perturbation theory and the slow–fast analysis method
cannot be directly used to explore the mechanism of the relaxation oscillations in the forced …

Synchrony-induced modes of oscillation of a neural field model

JM Esnaola-Acebes, A Roxin, D Avitabile, E Montbrió - Physical Review E, 2017 - APS
We investigate the modes of oscillation of heterogeneous ring networks of quadratic
integrate-and-fire (QIF) neurons with nonlocal, space-dependent coupling. Perturbations of …

Bifurcation analysis for simplified five-neuron bidirectional associative memory neural networks with four delays

C Xu, M Liao, P Li, Y Guo - Neural processing letters, 2019 - Springer
The paper deals with the stability and bifurcation analysis of a class of simplified five-neuron
bidirectional associative memory neural networks with four delays. By discussing the …

Conditions for wave trains in spiking neural networks

J Senk, K Korvasová, J Schuecker, E Hagen… - Physical review …, 2020 - APS
Spatiotemporal patterns such as traveling waves are frequently observed in recordings of
neural activity. The mechanisms underlying the generation of such patterns are largely …

Neural field models with transmission delays and diffusion

L Spek, YA Kuznetsov, SA van Gils - The Journal of Mathematical …, 2020 - Springer
A neural field models the large scale behaviour of large groups of neurons. We extend
previous results for these models by including a diffusion term into the neural field, which …

Switching to nonhyperbolic cycles from codimension two bifurcations of equilibria of delay differential equations

MM Bosschaert, SG Janssens, YA Kuznetsov - SIAM Journal on Applied …, 2020 - SIAM
In this paper, we perform the parameter-dependent center manifold reduction near the
generalized Hopf (Bautin), fold-Hopf, Hopf-Hopf, and transcritical-Hopf bifurcations in delay …

Stability of the twisted states in a ring of oscillators interacting with distance-dependent delays

YH An, MS Ho, RS Kim, CU Choe - Physica D: Nonlinear Phenomena, 2024 - Elsevier
We consider a ring of phase oscillators interacting with distance-dependent time delays in
general forms. It is found that the distance-dependent interaction delay is an essential …
