We analyze spiking responses of excitable neuron model with a winding threshold manifold on a pulse stimulation. The model is stimulated with external pulse stimuli and can generate nonlinear integrateand-fire and resonant responses typical for excitable neuronal cells (all-or-none). In addition we show that for certain parameter range there is a(More)
The soliton dynamics is studied using the Frenkel Kontorova (FK) model with nonconvex interparticle interactions immersed in a parameterized on-site substrate potential. The case of a deformable substrate potential allows theoretical adaptation of the model to various physical situations. Non-convex interactions in lattice systems lead to a number of(More)
