Waves in Diffusively Coupled Bursting Cells

چکیده
We analyze the dynamics of a spatially extended system with bistability between a homogeneous stationary state and an unstable fixed point surrounded by an oscillatory state. We show that a wave front extinguishes homogeneous oscillations, replacing them with unsteady oscillations. A traveling wave solution connects the unsteady oscillations to the stationary state. The difference in potentials of the fixed points alone determines the velocity of the wave-front fixed points. We apply our results to a generic model of neuronal bursting. [S0031-9007(99)08785-2]

Bursting Near homoclinic bifurcation in Two Coupled Chua oscillators
We report experimental observation of cycle-cycle bursting near homoclinic bifurcation in a selfoscillating Chua oscillator when it is diffusively coupled to another excitable Chua oscillator. The excitable oscillator induces an asymmetry in the self-oscillating Chua oscillator via coupling. The coupling strength controls the strength of the asymmetry that plays a key role in transition to burs...
متن کاملPeriodic calcium waves in coupled cells induced by internal noise
We show that internal stochasticity, originating from finite cell sizes and related small numbers of reactant ions participating in the dynamics, is able to extract a characteristic spatial frequency of calcium waves in the medium of diffusively coupled cells. Internal noise is thereby the only agent acting on the system. As the spatial periodicity is best pronounced at an intermediate level of...
متن کاملDelayed feedback control of three diffusively coupled Stuart-Landau oscillators: a case study in equivariant Hopf bifurcation.
The modest aim of this case study is the non-invasive and pattern-selective stabilization of discrete rotating waves ('ponies on a merry-go-round') in a triangle of diffusively coupled Stuart-Landau oscillators. We work in a setting of symmetry-breaking equivariant Hopf bifurcation. Stabilization is achieved by delayed feedback control of Pyragas type, adapted to the selected spatio-temporal sy...
متن کاملSynchronization of slow-fast systems
Abstract. We describe different patterns of synchronization of two systems, each possessing oscillations on two very different time scales. Synchronization of slow and fast oscillations are characterized separately, leading to a possibility to observe partially synchronized states where, e.g., the slow motions are synchronous while the fast are desynchronized. As a first example we study two di...
متن کاملTransition to Higher Chaos in Diffusively Coupled Chemical Oscillators *
Highly irregular spatio-temporal behavior in reaction-diffusion systems is often referred to as chemical turbulence [1]. Rössler proposed that one possible road to turbulence is via the chaotic hierarchy, i.e., with stepwise increasing number of positive Lyapunov characteristic exponents (LCEs) in finite-dimensional systems [2]. He showed that two diffusively coupled nonlinear oscillators were ...
