Dynamics of individual neurons

Deterministic description of oscillatory activities in neurons is given within the framework of theory of dynamical systems and bifurcations. Mathematically, the corresponding, conductance based model belongs to a class of dynamical systems with several distinct time scales.  Dr. Shilnikov’s research group focuses its research on the origin of complex behavioral dynamics and preceding bifurcation sequences in neuronal models. We develop the geometric tools of slow-fast systems and the advanced, analytical and computational technique of the global bifurcation theory to model and understand in-depth the nonlinear dynamics of single neurons. 

Polyrhythms and Multistability in CPG networks

Bursting is a manifestation of the slow-fast dynamics observed in neuroscience including central pattern generators controlling animal locomotion.  The emergence of synchronous rhythms in neural networks is closely related to temporal characteristics of the coupled neurons due to both their intrinsic properties and types of synaptic coupling, inhibitory and excitatory. When cells are near the transition edge between bursting and tonic spiking, the dynamics of the network become highly sensitive to small perturbations due to changes in the architecture of the network and of strength of synaptic coupling. Research of Dr. Shilnikov’s group focuses on synergetic mechanisms of dynamical designation of pacemakers on a network endowing it with flexible synchronization properties leading to the multistability of coexistent bursting rhythms.
