“…Another important application is concerned with signal processing. In this direction, VR has been proposed for the transmission, filtering and amplification of signals; such applications have been demonstrated both theoretically and experimentally [78] , [79] , [80] , [81] . In rotational machinery quite generally, bearings play crucial roles e.g.…”

“…For example, an inhibitory autapse with time delay, which corresponds to a slow autapse, can enhance firing frequency, which is a novel phenomenon different from the common viewpoint that inhibitory effects should induce the reduction of firing frequency 59 . An inhibitory autapse can induce the enhancement of signal transmission in neuronal networks 60 , and the enhancement of bursting 61 has been simulated and analyzed in theoretical models. An excitatory or inhibitory autapse can induce a transition between type I and II excitability 15,16 .…”

Neuronal excitability is classified as type I, II, or III, according to the responses of electronic activities, which play different roles. In the present paper, the effect of an excitatory autapse on type III excitability is investigated and compared to type II excitability in the Morris-Lecar model, based on Hopf bifurcation and characteristics of the nullcline. The autaptic current of a fast-decay autapse produces periodic stimulations, and that of a slow-decay autapse highly resembles sustained stimulations. Thus, both fast- and slow-decay autapses can induce a resting state for type II excitability that changes to repetitive firing. However, for type III excitability, a fast-decay autapse can induce a resting state to change to repetitive firing, while a slow-decay autapse can induce a resting state to change to a resting state following a transient spike instead of repetitive spiking, which shows the abnormal phenomenon that a stronger excitatory effect of a slow-decay autapse just induces weaker responses. Our results uncover a novel paradoxical phenomenon of the excitatory effect, and we present potential functions of fast- and slow-decay autapses that are helpful for the alteration and maintenance of type III excitability in the real nervous system related to neuropathic pain or sound localization.

“…Following its introduction by Landa & McClintock [23] and motivated by the aforementioned potential applications, VR has now been demonstrated and analysed in a diversity of model systems theoretically, numerically and experimentally, cutting across many fields such as neuroscience, plasma physics, laser physics, acoustics and engineering. Specifically, the VR phenomenon has been investigated in bistable systems [24,28–35], multistable systems [36,37], ratchet devices [38], excitable systems [39], quintic oscillators [40–44], coupled oscillators [25,45–47], overdamped systems [30], delayed dynamical systems [44,46,48–52], asymmetric Duffing oscillators [53], fractional order oscillators [32,42,54], neural models [39,50,55–61], oscillatory networks [46,55,58–60,62–64], biological nonlinear systems [49,61,64], parametrically excited systems [34,65–69], systems with nonlinear damping [37,70–72], and deformed potential [73], disordered systems [74], quantum systems [75,76], as well as harmonically trapped and roughed potentials [72,77]. More importantly, VR has been demonstrated in experimental realizations, especially in multistable systems, arrays of hard limiters, bistable vertical-cavity surface-emitting lasers [28,29,33,78–81] and Chua circuits [82,83].…”

The vibrational resonance (VR) phenomenon has received a great deal of research attention over the two decades since its introduction. The wide range of theoretical and experimental results obtained has, however, been confined to VR in systems with constant mass. We now extend the VR formalism to encompass systems with position-dependent mass (PDM). We consider a generalized classical counterpart of the quantum mechanical nonlinear oscillator with PDM. By developing a theoretical framework for determining the response amplitude of PDM systems, we examine and analyse their VR phenomenona, obtain conditions for the occurrence of resonances, show that the role played by PDM can be both inductive and contributory, and suggest that PDM effects could usefully be explored to maximize the efficiency of devices being operated in VR modes. Our analysis suggests new directions for the investigation of VR in a general class of PDM systems. This article is part of the theme issue ‘Vibrational and stochastic resonance in driven nonlinear systems (part 1)’.
