In the center of attention of our Division lies the analysis of biological signals and modeling of the electrical brain activity. We develop models and advanced methods of time series analysis, especially these connected with the nervous system (electroencephalograms, electrocorticograms, event related potentials, local field potentials and otoacoustic emissions in humans and animals) for research and clinical applications. The research involves cooperation with many laboratories, in particular Harvard Medical School, Johns Hopkins School of Medicine, Universities of Amsterdam and Ferrara and others.

The results of our investigations allow for determination of sources of brain activity and topographical dynamic patterns of signals propagation, which made possible e.g. finding physical correlates of motor control and elucidation of processes of information transfer in brain.

Methods based upon adaptive time-frequency parameterization of signals (matching pursuit), developed in our Department, provide a unique tool for micro- and macro-scale analysis of the signal, and allow for a unification of the traditional, clinical analysis of EEG with advanced signal processing, which has impact on both clinical and research applications.

Modeling of the oscillatory electrical activity of the neural assemblies during normal and pathological states of brain, in particular, in case of epilepsy is aimed to revel basic mechanisms of seizure generation and to develop rational methods for seizure prediction and control.
