Noise-Induced Synchronization and Desynchronization of Neural Oscillators

We study an influence of white Gaussian noise on synchrony of neural oscillators. In neurophysiology, the property of a single neuron to provide identical outputs for repeated noisy input (in terms of our problem, an array of such identical neurons driven by common noise to behave synchronously) is referred as “reliability” [1]. The first quantifier of the synchrony we use is the Lyapunov expon...

Global Synchronization and Selective Desynchronization of FitzHugh{Nagumo Oscillators

In this paper we adopt a correlation approach to neuronal modeling of visual perception, using oscillations. We propose a hierarchy of processing modules corresponding to di erent levels of representation. The rst layer consists of an array of FitzHugh-Nagumo oscillators, which receive a grey{level image as external input. The dynamic behaviour of the coupled oscillators is rigorously investiga...

Synchronization and desynchronization of self-sustained oscillators by common noise.

We consider the effect of external noise on the dynamics of limit cycle oscillators. The Lyapunov exponent becomes negative under influence of small white noise, what means synchronization of two or more identical systems subject to common noise. We analytically study the effect of small non-identities in the oscillators and in the noise, and derive statistical characteristics of deviations fro...

Adaptive Synchronization of Neural and Physical Oscillators

Shuji Yoshizawa University of Tokyo Bunkyo-ku, Tokyo 113, Japan Animal locomotion patterns are controlled by recurrent neural networks called central pattern generators (CPGs). Although a CPG can oscillate autonomously, its rhythm and phase must be well coordinated with the state of the physical system using sensory inputs. In this paper we propose a learning algorithm for synchronizing neural ...

Hub induced remote synchronization and desynchronization in complex networks of Kuramoto oscillators

Abstract The concept of “remote synchronization” (RS) was introduced in [Phys. Rev. E 85, 026208 (2012)], where synchronization in a star network of Stuart-Landau oscillators was investigated. In the RS regime therein described, the central hub served as a transmitter of information between peripheral nodes, while maintaining independent dynamics that were asynchronous with the rest of the netw...
