Nonlinear and Symbolic Dynamics in Biosignal Analysis

GBAF consists of Physicists, but we have strong collaboration with Medical Doctors, Biologists, and Engineers. 

Brief expertise description:

·         Developing new methods (algorithms) for online and real-time biosignal processing and analysis, based on nonlinear and symbolic dynamics, and implementing such new methods  in data recording / data acquisition systems, in collaboration with Engineers;

·         Application of these algorithms to EEG, for alertness monitoring, sleep staging, assessment of depth of anaesthesia, influence of drugs, epileptic seizure foreseeing, and to biofeedback; the methods are also applicable to analysis of other biosignals;

·         Real-time signal processing for sleep monitoring, e.g. developing of automatic sleep stager, based on these algorithms, in collaboration with Medical Doctors.

·         Specialist training and dissemination of knowledge to general public

Before any signal generated e.g. by human body or brain may be appropriately used, i.e. for monitoring of the brain state or for control purposes, that signal has to be appropriately processed and visualized. In most cases there is a necessity to apply special data-processing algorithms. Research needs to draw upon multiple disciplines to create novel algorithms and computational methods for biosignal registration and modeling, for extraction, fusion and visualization of multi-modal information, for representing and managing signal complexity. It is necessary to develop methods that are computationally effective, i.e. that enable to extract and apply useful information to specific tasks in a timely fashion; of particular interest is development of real-time methods. These advances may have relevance in all fields requiring human-machine cooperation. GBAF develops such new methods of signal processing based on nonlinear and symbolic dynamics; these methods are simple and may be used for analysis of non-stationary, noisy signals, for which there exist no analytical models.

In the Ochota Campus in Warsaw there are also located other research Institutes of the Polish Academy of Sciences, Central Clinics of the Warsaw Academy of Medicine, and good facilities to organize training and conferences for competitive prices. These facilities were used e.g. for summer schools EUROATTRACTOR (European Interdisciplinary Schools on Nonlinear Dynamics for System and Signal Analysis) in the Fifth Framework Programme.

The Institute has also Department of Neurosurgery with a clinic of its own.
