Electroencephalogram and adaptive approximations of signals Research on the electrical activity of the brain (electroencephalogram, EEG) has over a 100 years history--with Polish scientists among the pioneers. In spite of rapid development of new brain imaging systems, EEG still retains a privileged position. With greatly improved recording techniques, analysis of these data poses nowadays a major challenge. New signal processing techniques, adaptive approximations, are suitable for analysis of non-stationary signals and provide time-frequency resolution superior to any of the previously known methods. A unified parametrization of transient and stationary phenomena is possible within presented framework.
