Large-scale neural dynamics: simple and complex

S Coombes - NeuroImage, 2010 - Elsevier
We review the use of neural field models for modelling the brain at the large scales
necessary for interpreting EEG, fMRI, MEG and optical imaging data. Albeit a framework that …

Consciousness is supported by near-critical slow cortical electrodynamics

D Toker, I Pappas, JD Lendner… - Proceedings of the …, 2022 - National Acad Sciences
Mounting evidence suggests that during conscious states, the electrodynamics of the cortex
are poised near a critical point or phase transition and that this near-critical behavior …

Theta-nested gamma oscillations in next generation neural mass models

M Segneri, H Bi, S Olmi, A Torcini - Frontiers in computational …, 2020 - frontiersin.org
Theta-nested gamma oscillations have been reported in many areas of the brain and are
believed to represent a fundamental mechanism to transfer information across spatial and …

Constructing chaotic systems with conditional symmetry

C Li, JC Sprott, H Xing - Nonlinear Dynamics, 2017 - Springer
Asymmetric dynamical systems sometimes admit a symmetric pair of coexisting attractors for
reasons that are not readily apparent. This phenomenon is called conditional symmetry and …

Constructing infinitely many attractors in a programmable chaotic circuit

C Li, WJC Thio, JC Sprott, HHC Iu, Y Xu - IEEE Access, 2018 - ieeexplore.ieee.org
In this paper, we modify the Sprott M chaotic system to provide infinitely many co-existing
attractors by replacing the offset boosting parameter with a periodic function giving what we …

A biophysical model of dynamic balancing of excitation and inhibition in fast oscillatory large-scale networks

RG Abeysuriya, J Hadida… - PLoS computational …, 2018 - journals.plos.org
Over long timescales, neuronal dynamics can be robust to quite large perturbations, such as
changes in white matter connectivity and grey matter structure through processes including …

Infinite lattice of hyperchaotic strange attractors

C Li, JC Sprott, T Kapitaniak, T Lu - Chaos, Solitons & Fractals, 2018 - Elsevier
By introducing trigonometric functions in a 4-D hyperchaotic snap system, infinite 1-D, 2-D,
and 3-D lattices of hyperchaotic strange attractors were produced. Furthermore a general …

Modeling brain resonance phenomena using a neural mass model

A Spiegler, TR Knösche, K Schwab… - PLoS computational …, 2011 - journals.plos.org
Stimulation with rhythmic light flicker (photic driving) plays an important role in the diagnosis
of schizophrenia, mood disorder, migraine, and epilepsy. In particular, the adjustment of …

Neurodynamics

S Coombes, KCA Wedgwood - Texts in applied mathematics, 2023 - Springer
This is a book about 'Neurodynamics'. What we mean is that this is a book about how ideas
from dynamical systems theory have been developed and employed in recent years to give …

Firing rate models for gamma oscillations

S Keeley, Á Byrne, A Fenton… - Journal of …, 2019 - journals.physiology.org
