Synchronization of Burstings Neurons in Clustered Networks with Small-world Property
نویسندگان
چکیده
Neuron activity presents two timescales, a fast one related to action potential spiking, and a slow timescale in which bursting takes place. Some pathological conditions are related with the synchronization of the bursting activity in a weak sense, meaning the adjustment of the bursting phase due to coupling. We investigated coupled Rulkov maps network with randomly distributed parameters, and exhibiting the small-world property. The clustered network exhibits collective oscillations in the form of synchronized bursting rhythms, without affecting the fast timescale dynamics. We analyzed global synchronization varying the probabilities of intracluster and intercluster connections. Numerical experiments appeared to have the same outcomes as analytical predictions. Besides, analysis of the distribution of the time of global synchronization showed a intermittent behaviour that is observed in epileptic activity.

Global synchronization of bursting neurons in clustered networks
We investigate the collective dynamics of bursting neurons on clustered network. The clustered network is composed of subnetworks each presenting a small-world property, and in a given subnetwork each neuron has a probability po to be connected to the other subnetworks. We give bounds for the critical coupling strength to obtain global burst synchronization in terms of the network structure, i....

We investigate the collective dynamics of bursting neurons on clustered networks. The clustered network model is composed of subnetworks, each of them presenting the so-called small-world property. This model can also be regarded as a network of networks. In each subnetwork a neuron is connected to other ones with regular as well as random connections, the latter with a given intracluster proba...

In this paper, a generalization of the Kuramoto model is introduced by explicit consideration of deterministically time-varying periodic external force. In this model, the oscillator's natural frequencies and amplitude of collective oscillations are influenced by external forces with constant or random strengths. Then, the synchronization behavior of forced Kuramoto model is studied in some com...
متن کاملChaotic phase synchronization in small-world networks of bursting neurons.
We investigate the chaotic phase synchronization in a system of coupled bursting neurons in small-world networks. A transition to mutual phase synchronization takes place on the bursting time scale of coupled oscillators, while on the spiking time scale, they behave asynchronously. It is shown that phase synchronization is largely facilitated by a large fraction of shortcuts, but saturates when...
