Article
This study explores the interaction between two distinct sites, termed the source and the sink, to analyze the possibility of spiral wave formation. To this aim, a grid of memristive FitzHugh–Nagumo elements is designed to simulate biological excitable media, such as the myocardium. The source, characterized by high excitation levels with a gradual...
Article
Disorders in the heart's conduction system can lead to the formation of rotating spiral waves, and terminating the re-entrant seeds is crucial to restore cardiac function. Myocyte action potential (AP) morphology is spatially dependent within the myocardium, forming an intrinsic gradient. This study investigates the impact of gradients in AP morpho...
Article
We study the spatiotemporal dynamics of spiral waves in a lattice of chemically coupled memristive FitzHugh–Nagumo neurons. We also introduce local and global functional inhomogeneities by means of variations in nodal action potentials that are distributed in different ways. We find that, in the presence of globally distributed random inhomogeneity...

We study the emergence of meandering spiral waves in a multilayer structure where two spirals, originating independently, evolve in space–time. The FitzHugh-Nagumo model, enhanced with electromagnetic induction effects, defines the nodal dynamics. The layers are chemically coupled, and the drift of spirals is influenced by interlayer flux coupling....

We study the formation and suppression of spiral wave patterns in a lattice of memristive FitzHugh–Nagumo neurons that are connected through chemical coupling. While earlier works focused predominantly on diffusive coupling, we focus on various parameters that determine the properties of chemical synapses, in particular their firing threshold, the...

The attempts to evaluate the synchronizability of chaotic systems have shown that additive periodic forcing, as a relevant source of stimuli, significantly impacts multiple forms of synchrony. This paper investigates the complete synchronizability of coupled periodically forced chaotic systems using the master stability function method. Three class...

The dynamical interplay of coupled non-identical chaotic oscillators gives rise to diverse scenarios. The incoherent dynamics of these oscillators lead to the structural impairment of attractors in phase space. This paper investigates the couplings of Lorenz–Rössler, Lorenz–HR, and Rössler–HR to identify the dominant attractor. By dominant attracto...
