Nonlinear dynamics underlying sensory processing dysfunction in schizophrenia

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance One of the fundamental challenges of neuroscience is to understand the seamless orchestration of many interconnected brain regions, which is needed to produce the integrated experience of cognition.

Characteristics of in-out intermittency in delay-coupled FitzHugh-Nagumo oscillators

, 2018
We analyze a pair of delay-coupled FitzHugh-Nagumo oscillators exhibiting in-out intermittency as a part of the generating mechanism of extreme events.

Complexity without chaos: Plasticity within random recurrent networks generates robust timing and motor control [PDF]

, 2012
It is widely accepted that the complex dynamics characteristic of recurrent neural circuits contributes in a fundamental manner to brain function. Progress has been slow in understanding and exploiting the computational power of recurrent dynamics for ...

Effects of additive noise on the stability of glacial cycles

, 2016
It is well acknowledged that the sequence of glacial-interglacial cycles is paced by the astronomical forcing. However, how much is the sequence robust against natural fluctuations associated, for example, with the chaotic motions of atmosphere and ...

Data assimilation in slow-fast systems using homogenized climate models [PDF]

, 2011
A deterministic multiscale toy model is studied in which a chaotic fast subsystem triggers rare transitions between slow regimes, akin to weather or climate regimes.

Graphical Structure of Attraction Basins of Hidden Chaotic Attractors: The Rabinovich-Fabrikant System [PDF]

International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2018
The attraction basin of hidden attractors does not intersect with small neighborhoods of any equilibrium point. To the best of our knowledge this property has not been explored using realtime interactive three-dimensions graphics.

Chaos in a double driven dissipative nonlinear oscillator [PDF]

, 2001
We propose an anharmonic oscillator driven by two periodic forces of different frequencies as a new time-dependent model for investigating quantum dissipative chaos.

Chaotic Griffiths Phase with Anomalous Lyapunov Spectra in Coupled Map Networks

, 2016
Dynamics of coupled chaotic oscillators on a network are studied using coupled maps. Within a broad range of parameter values representing the coupling strength or the degree of elements, the system repeats formation and split of coherent clusters.

Effect of Random Parameter Switching on Commensurate Fractional Order Chaotic Systems

, 2016
The paper explores the effect of random parameter switching in a fractional order (FO) unified chaotic system which captures the dynamics of three popular sub-classes of chaotic systems i.e. Lorenz, Lu and Chen's family of attractors.

How single neuron properties shape chaotic dynamics and signal transmission in random neural networks

, 2019
While most models of randomly connected networks assume nodes with simple dynamics, nodes in realistic highly connected networks, such as neurons in the brain, exhibit intrinsic dynamics over multiple timescales.
