Makarov Slizneva, ValeriyNekorkin, Vladimir I.Velarde, Manuel G.2023-06-202023-06-202001-04-090031-900710.1103/PhysRevLett.86.3431https://hdl.handle.net/20.500.14352/57693We show that firing activity (spiking) can be regularized by noise in a FitzHugh-Nagumo (FHN) neuron model when operating slightly beyond the supercritical Hopf bifurcation (in the "canard" region). We also provide the conditions for imperfect phase Locking between interspike intervals and low amplitude quasiharmonic oscillations. For the imperfect phase locking no need exists of an external signal as it follows from the FHN intrinsic dynamics.engjournal articlehttp://prl.aps.org/abstract/PRL/v86/i15/p3431_1http://prl.aps.org/open access612.8Aperiodic stochastic resonanceCoherence resonanceExcitable systemsInferior oliveNeuronsModulationMechanismNeurociencias (Biológicas)2490 Neurociencias
