Spatiotemporal characteristics in systems of diffusively coupled excitable slow–fast FitzHugh–Rinzel dynamical neurons

A Mondal, A Mondal, S Kumar Sharma… - … Journal of Nonlinear …, 2021 - pubs.aip.org
In this paper, we study an excitable, biophysical system that supports wave propagation of
nerve impulses. We consider a slow–fast, FitzHugh–Rinzel neuron model where only the …

Isolated Spiral Solutions of the Ginzburg–Landau Equation

A Guzmán-Velázquez, A Ledesma-Durán… - … Journal of Bifurcation …, 2024 - World Scientific
Using finite element simulation, we study the main features of rotating wave solutions of the
cubic complex Ginzburg–Landau equation. To focus on the characteristics of the waves …

Pattern formation in a two-dimensional array of oscillators with phase-shifted coupling

PJ Kim, TW Ko, H Jeong, HT Moon - … Review E—Statistical, Nonlinear, and Soft …, 2004 - APS
We investigate the dynamics of a two-dimensional array of oscillators with phase-shifted
coupling. Each oscillator is allowed to interact with its neighbors within a finite radius. The …

Amplitude equations for reaction-diffusion systems with cross diffusion

EP Zemskov, VK Vanag, IR Epstein - … Review E—Statistical, Nonlinear, and Soft …, 2011 - APS
Using Taylor series expansion, multiscaling, and further expansion in powers of a small
parameter, we develop general amplitude equations for two-variable reaction-diffusion …

Emergence of spiral and antispiral patterns and its CGLE analysis in leech-heart interneuron model with electromagnetic induction

RK Upadhyay, D Pradhan, SK Sharma… - Applied Mathematical …, 2024 - Elsevier
Neurons can exhibit various rhythmic activities such as bursting, spiking, and quiescent
states when exposed to external input current stimulus. In this paper, a model of medicinal …

Dynamical structures in binary media of potassium-driven neurons

DE Postnov, F Müller, RB Schuppner… - Physical Review E …, 2009 - APS
According to the conventional approach neural ensembles are modeled with fixed ionic
concentrations in the extracellular environment. However, in some cases the extracellular …

Spiral waves in population density distributions of invasive pests in warm-temperate deciduous forest ecosystems

J Gao, C Gu, C Shen, H Yang - Europhysics Letters, 2022 - iopscience.iop.org
Globally, forests are increasingly being affected by invasive alien pests, some of which have
caused wholesale destruction of trees. Recent research suggests that, in the United States …
