Hyperpolarization-activated cyclic nucleotide-gated cation current ( ) plays important roles in the achievement of many physiological/pathological functions nervous system by modulating electrophysiological activities, such as rebound (spike) to hyperpolarization stimulations, subthreshold membrane resonance sinusoidal currents, and spike-timing precision stochastic factors. In present paper, with increasing (conductance ), appear become stronger, variability interspike intervals (ISIs)...
The inter-burst intervals (IBIs) of the stochastic bursting caused by effect coherence resonance (CR) in Hindmarsh-Rose model exhibited multiple mode and were approximately integer multiples a basic IBI. A similar pattern was found experiment on an experimental neural pacemaker perfused with solution whose extracellular calcium concentration ([Ca2+]o) lower than normal level which firing period 1 spiking. results verified existence implied its CR mechanism. In addition, distinction between...
Time-delay-induced synchronous behaviors and synchronization transitions have been widely investigated for coupled neurons, they play important roles physiological functions. In the present study, time-delay-induced synchronized subthreshold oscillations were simulated, bifurcations underlying identified a pair of FitzHugh–Nagumo neurons. Multiple between in-phase anti-phase synchronizations induced by time delay simulated inhibitory excitatory couplings. Subcritical or supercritical Hopf...
Abstract Neuronal excitability is classified as type I, II, or III, according to the responses of electronic activities, which play different roles. In present paper, effect an excitatory autapse on III investigated and compared II in Morris-Lecar model, based Hopf bifurcation characteristics nullcline. The autaptic current a fast-decay produces periodic stimulations, that slow-decay highly resembles sustained stimulations. Thus, both fast- autapses can induce resting state for changes...
A series of new firing patterns lying between two kinds periodic bursting and randomly alternating on the bursts, were discovered in experiment neural pacemaker induced by noise Chay model near each bifurcation point a period adding scenario without chaos, exhibiting multi-mode characteristics that was signature autonomous stochastic resonance neuronal firing. Two endogenous made induce identified. One there existed critical phase trajectories patterns. The other periods small.
Coherence resonance (CR) describes a counterintuitive phenomenon in which the optimal oscillatory responses nonlinear systems are shaped by suitable noise amplitude. This has been observed neural systems. In this research, generation of double coherence resonances (DCRs) due to white is investigated three-dimensional reduced Hodgkin-Huxley neuron model with multiple-timescale feature. We show that additive can induce DCRs from resting state near subcritical Hopf bifurcation. The appearance...
Time variant signals received by a neuron were encoded into and output in the changing firing patterns. Recent investigations revealed that patterns changed according to certain bifurcation principles. Thus, scenarios among various fundamental study of neural coding. In this one previous theoretically proposed scenarios, period adding without chaos, was experimentally confirmed exist real neuronal activities. The realistic process possessed integer multiple not found theoretical reports....
<abstract><p>Mixed-mode oscillations (MMOs) consisting of spikes alternating with a series subthreshold have been observed in various neurons related to some physiological functions. In the present paper, inhibitory-autapse-induced MMOs are simulated by using Hodgkin-Huxley neuron model, and underlying dynamical mechanism is identified be dynamics unstable behaviors near subcritical Hopf bifurcation. For monostable spiking, delayed inhibitory current pulse activated spike can...
