Amplitude chimeras and bump states with and without frequency entanglement: a toy model
Astero Provata
When chaotic oscillators are coupled in complex networks a number of interesting synchronization phenomena emerge. Notable examples are the frequency and amplitude chimeras, chimer…
Structural anomalies in brain networks induce dynamical pacemaker effects
I. Koulierakis, D. A. Verganelakis, I. Omelchenko +3
Dynamical effects on healthy brains and brains affected by tumor are investigated via numerical simulations. The brains are modeled as multilayer networks consisting of neuronal os…
Chimera states in ring-star network of Chua circuits
S. S. Muni, A. Provata
We investigate the emergence of amplitude and frequency chimera states in ring-star networks consisting of identical Chua circuits connected via nonlocal diffusive, bidirectional c…
Chimera patterns in two-dimensional networks of coupled neurons
Alexander Schmidt, Theodoros Kasimatis, Johanne Hizanidis +2
We discuss synchronization patterns in networks of FitzHugh-Nagumo and Leaky Integrate-and-Fire oscillators coupled in a two-dimensional toroidal geometry. Common feature between t…
Multi-chimera states in the Leaky Integrate-and-Fire model
N. D. Tsigkri-DeSmedt, J. Hizanidis, P. Hoevel +1
We study the dynamics of identical leaky integrate-and-fire neurons with symmetric non-local coupling. Upon varying control parameters (coupling strength, coupling range, refractor…
Robustness of chimera states for coupled FitzHugh-Nagumo oscillators
Iryna Omelchenko, Astero Provata, Johanne Hizanidis +2
Chimera states are complex spatio-temporal patterns that consist of coexisting domains of spatially coherent and incoherent dynamics. This counterintuitive phenomenon was first obs…
