We investigate numerically the collective dynamical behavior of pulse-coupled nonleaky integrate-and-fire neurons that are arranged on a two-dimensional small-world network. To ensure ongoing activity, we impose a probability for spontaneous firing for each neuron. We study network dynamics evolving from different sets of initial conditions in dependence on coupling strength and rewiring probability. Besides a homogeneous equilibrium state for low coupling strength, we observe different local…

Irregular macroscopic dynamics due to chimera states in small-world networks of pulse-coupled oscillators

We study the collective dynamics of excitatory integrate-and-fire-like oscillators interacting via δ-pulses on a small-world network. The oscillators are endowed with refractory periods and time

Linking Network Structure and Transient and Equilibrium Integrate-and-Fire Dynamics

This work investigates a relationship with respect to the integrate-and-fire dynamics emanating from a source node and an extended network model that allows control of the small-world feature as well as the length of the long-range connections and confirms that the dynamical features before the avalanches can be accurately predicted from structural features.

Transitions between dynamical behaviors of oscillator networks induced by diversity of nodes and edges.

It is shown that the probability for a network to exhibit a certain dynamical behavior (network susceptibility) is affected differently by dynamical and structural heterogeneity and depends on the respective homogeneous dynamics.

Phase multistability in a dynamical small world network.

The effect of phase multistability is explored in a small world network of periodic oscillators with diffusive couplings and the dynamics of random couplings is modeled by "birth" and "death" stochastic processes by means of the cellular automate approach.

Diverse self-sustained oscillatory patterns and their mechanisms in excitable small-world networks.

Diverse self-sustained oscillatory patterns and their mechanisms in small-world networks of excitable nodes are studied and the mechanism of emergence and annihilation of synchronizing oscillations is explained using the shortest path length analysis.

Chaotic phase synchronization in small-world networks of bursting neurons.

It is demonstrated that there exists an optimal small-world topology, resulting in the largest peak value of frequency locking interval in the parameter plane, where bursting synchronization is maintained, even with the external driving.

Spreading dynamics on spatially constrained complex brain networks

It is shown that the cortical geometry influences profoundly the speed of propagation of activation through the network and indicates that such studies which omit physiological network structure risk simplifying the dynamics in a potentially significant way.

Mechanisms of Seizure Propagation in 2-Dimensional Centre-Surround Recurrent Networks

An analysis of the speed of propagation in a computational model of seizure-like activity in a 2-dimensional recurrent network of integrate-and-fire neurons containing both excitatory and inhibitory populations and having a difference of Gaussians connectivity structure, an approximation to that observed in cerebral cortex is presented.



Global and local synchrony of coupled neurons in small-world networks

It is shown that the dispersion of the number of connections for neurons influences dynamical behavior even if other major topological statistics are kept fixed and the rewiring probability parameter representing the randomness of networks bridges two spatially opposite frameworks: precise local synchrony and rough global synchrony.

Multiple attractors, long chaotic transients, and failure in small-world networks of excitable neurons.

It is found that persistent activity emerges at low density of shortcuts, and that the system undergoes a transition to failure as their density reaches a critical value, with multiple stable periodic attractors below this transition.

Self-sustained activity in a small-world network of excitable neurons.

The dynamics of excitable integrate-and-fire neurons in a small-world network is studied, finding thatceedingly long transients emerge at higher densities p; their activity patterns are disordered, in contrast to the mostly periodic persistent patterns observed at low p.

Cluster synchronization and spatio-temporal dynamics in networks of oscillatory and excitable Luo-Rudy cells.

This work focuses on the transition from incoherent behavior to global synchronization via cluster synchronization regimes as coupling strength is increased, and describes spatio-temporal patterns arising during this transition, including pacemakers, spiral waves, and complicated irregular activity.

Desynchronization waves in small-world networks.

A general type of the Kardar-Parisi-Zhang equation is derived for phase evolution in a prototype oscillator network and demonstrates well the ordered desynchronized wave patterns found in the network with and without shortcuts.

Frustration, drift, and antiphase coupling in a neural array.

It is found that an array of 20x20 coupled neurons undergoes a series of alternating low and high synchronization states, as measured by phase-locking and frequency entrainment, as the coupling constant is tuned.

Dynamics of neural populations: Stability and synchrony

The result that synchronous behavior can exist only for a narrow range of time delays, which range is an order of magnitude smaller than periods of oscillation is shown.

Traveling waves and pulses in a one-dimensional network of excitable integrate-and-fire neurons

A self-consistency condition for the existence of traveling waves is derived, which generates a dispersion relation between velocity and wavelength, and an integro-difference equation of infinite order is used to analyze the stability of solitary pulses in the long-wavelength limit.

The Number of Synaptic Inputs and the Synchrony of Large, Sparse Neuronal Networks

An approximate theory for sparse networks of identical neurons is developed that predicts with remarkable accuracy the value of Mc and the patterns of synchrony above Mc, provided the synaptic coupling is not too large and the strong coupling regime of inhibitory sparse networks is studied.

Emergence of self-sustained patterns in small-world excitable media.

Two distinct dynamical transitions in the activity of excitable media where waves propagate both between neighboring regions and through LRCs are observed, resulting in a spatially homogeneous, temporally periodic state.
