Analysis of the galvanic skin response
Caha, Martin ; Chmelař, Milan (referee) ; Ronzhina, Marina (advisor)
This work deals with the analysis of skin conductance for the study of the psychophysiological state of man, with a focus on the change in the level of arousal. It is important to study microsleep events during driving, where there are the changes in alertness and consequently the changes in skin conductivity. The experimental protocol is proposed. Skin conductance analysis is realized in Matlab. This program allows drowing reaction time and measured conductivities and calculating their parameters. These data are used for determination of vigilance level.

Analysis of electroencephalograms
Gajdoš, Martin ; Rozman, Jiří (referee) ; Kolářová, Jana (advisor)
Electroencephalography is sensitive diagnostic method for measuring electric potentials generated by brain. In this project are described the properties of the EEG signal and methods of EEG measuring, processing and evaluating. Also the noise sources and methods for noise removing are described. The project deals in the second part with detection of drowsiness and microsleep from driver’s EEG. At first theoretically, then is shown the practical measurement of EEG on volunteers. During the measurement was intention to induce drowsiness and microsleep. Finally is described the processing of measured EEG signals and the results are visualized.
