The synchronization of populations interacting spiking neurons is a topic interest for understanding the operation brain and developing oscillatory-based biomimetic computation. analysis by models such as Hodgkin–Huxley (HH) FitzHugh–Nagumo (FHN) based on electrical electrochemical concepts. application small-signal AC impedance equivalent circuit methods promising tool fabrication artificial s...

We discuss features of the inflaton potential that can lead to a strong enhancement power spectrum curvature perturbations. show steep decrease induces an by several orders magnitude, which may production primordial black holes. The same feature also create distinctive oscillatory pattern in gravitational waves generated through scalar perturbations at second order. study additive effect such f...

The decay of metastable patterns in the form of magnetic liquid ridges is studied in the frame of a linear stability analysis where the ridges are the most unstable linear pattern of the Rosensweig instability. The analysis of the corresponding dispersion relation reveals that different sets of solutions exist. Two of them are associated with an oscillatory and a pure exponential decay, respect...

It is hypothesised that Parkinson’s disease is explained as a change in the pattern of synchronisation of discharges between neurons within the subthalamo-pallidal-thalamo-cortical circuit. By simulating a single GPi neuron receiving non-synchronous and oscillatory inputs the conditions required for the generation of normal and Parkinsonian patterns are determined.

The generation of oscillatory activity may be crucial to brain function. The coordination of individual neurons into rhythmic and coherently active populations is thought to result from interactions between excitatory and inhibitory cells mediated by local feedback connections. By using extracellular recording wires and silicon microprobes to measure electrically evoked damped oscillatory respo...
