Processing of EEG signals in frequency domain
 Nováková, Jarmila ; Potočňák, Tomáš (referee) ; Kozumplík, Jiří (advisor)
Sleep EEG is occupied by this project. It is aimed at processing signal which precede test of stationarity. It also deals with the issue of stationarity of sleep EEG with indicating of three types of segmentations. Principles of three types of segmentation are explained and their realization is compiled in the environment of Matlab by the way which enables to choose different input parameters. The change of stationarity is examined in various stages of sleep with the help of the results thus created functions. Another aspect of this study is the investigation of changes in the development of absolute and relative power over time according to transition between stage of wakefulness and stage of sleep. It is searched for the occurrence of these changes also in the development of the coherence spectra.
