Selected methods of biomedical signal analysis based on EEG records for cases of epileptic seizures

In the field of neurology ElectroEncephaloGraphic (EEG) measurements constitute one of the tools for today's clinical misdiagnosis. The interval years knowledge of specialists in the interpretation of individual disorders neurological dysfunction is based on collected records in both paper and electronic form. Even though the collected numerous databases records EEG interpretation and the fault finding procedure is a very big problem. Development of modern diagnostic technology allows you to reduce hardware limitations, which generate many artifacts (errors) which prevent correct diagnosis. One with a dynamically developing tools is the analysis and interpretation of EEG signals by applying spectral analysis techniques. These techniques allow visualization of signal power spectrum depending on frequency components. The article describes an experiment on samples actual registered spotting seizures EEG measurements collected in close cooperation of medical staff of the Ward of Neurology and Strokes of the Provincial Hospital of Zielona Góra.
