Networks of Motoneurons with Mixed-Mode Oscillations
In this paper we study the role of Mixed-Mode Oscillations (MMOs), observed experimentally in motoneurons, in the dynamics of different networks. As control parameters we have the applied current (Iapp) and the coupling strength (Ggap) between pairs of neurons. By fixing the value of one of these parameters, we analyze the dynamics in the network with identical neurons via a synchrony measure (...
متن کاملMixed-mode oscillations in complex-plasma instabilities.
Instabilities in dusty plasmas are frequent phenomena. We show that some instabilities can be described by mixed-mode oscillations often encountered in chemical systems or neuronal dynamics and studied through dynamical system theories. The time evolution of these instabilities is studied through the change in the associated waveform. Frequency and interspike interval are analyzed and compared ...
متن کاملMixed-Mode Oscillations with Multiple Time Scales
Mixed-mode oscillations (MMOs) are trajectories of a dynamical system in which there is an alternation between oscillations of distinct large and small amplitudes. MMOs have been observed and studied for over thirty years in chemical, physical, and biological systems. Few attempts have been made thus far to classify different patterns of MMOs, in contrast to the classification of the related ph...
متن کاملMechanism and Function of Mixed-Mode Oscillations in Vibrissa Motoneurons
Vibrissa motoneurons in the facial nucleus innervate the intrinsic and extrinsic muscles that move the whiskers. Their intrinsic properties affect the way they process fast synaptic input from the vIRT and Bötzinger nuclei together with serotonergic neuromodulation. In response to constant current (I(app)) injection, vibrissa motoneurons may respond with mixed mode oscillations (MMOs), in which...
متن کاملMixed-Mode Oscillations in a Stochastic, Piecewise-Linear System
We analyze a piecewise-linear FitzHugh-Nagumo model. The system exhibits a canard near which both small amplitude and large amplitude periodic orbits exist. The addition of small noise induces mixed-mode oscillations (MMOs) in the vicinity of the canard point. We determine the effect of each model parameter on the stochastically driven MMOs. In particular we show that any parameter variation (s...
