Analysis of the EEG signal: the methods and challenges

 Abstract:   Electroencephalogram (EEG) is an electric signal recorded from
            the scalp. This signal has been used for the last half of century
            to diagnose neurological diseases (e.g. epilepsy) and to
            investigate brain functioning in psychological experiments.
            Although the technique is old, recently it attracts lot of
            interest because the advances in signal processing allows to
            extract from the signal more and more information.

            This talk will review the currently used methods of analyzing
            EEG signal, which will include: analyzing the averaged wave
            forms, time-frequency analysis, analysis of coherence between
            brain regions, independent component analysis, and source
            localization. In the end, the open problems will be presented
            and possible solutions discussed.
