Generation of slow rhythms and sequential activity in ensembles of neuron-like oscillators

Recent experimental and theoretical studies indicate that slow brain rhythms are generated by simple inhibitory neural networks. Sequential switching of tonic spiking activity is a widespread phenomenon underlying such rhythms. In this paper, we analyze a minimal, reciprocally connected circuit of three spiking units in the cases of different excitability classes of models. It is shown that in both types arising of stable heteroclic contour produces sequentail activation and slow rhythm generation in neural microcircuit.

Nonlinear dynamics at the v congress of biophysicists of russia

A brief review of reports at the V Congress of Biophysicists of Russia (Rostov-on-Don, 4–10 October 2015) is presented in which the results are based on the methods of nonlinear dynamics. Stochastic methods are widely represented obtaining new results in neurodynamics and theory of molecular motors. Molecular dynamics simulations include now not only dynamics of separate molecules, but complex molecular systems like ion channels incorporated in lipid membrane.
