Biofeedback and its practical use
Dvořák, Jiří ; Hrozek, Jan (referee) ; Čmiel, Vratislav (advisor)
The aim of this work is describe common methods of biological feedback therapy that is used to treat some psychosomatic diseases. Subsequently, the description is focused on minimal brain dysfunction treatment by the help of EEG biofeedback. Properties and technical requirements for this therapy are concretized. The last part of this thesis is dedicated to the design and realization of practical software tool for EEG biofeedback therapy which is made in LabView 7.1. The M535 acquisition unit and NI USB-6221 measuring device are used for hardware solution.

Alpha monitor
Svobodová, Eva ; Kolářová, Jana (referee) ; Chmelař, Milan (advisor)
The master´s thesis presents the problems of EEG biofeedback and its application to relax people. The first part discusses the properties of EEG signal , the requirements of the standard EEG and also distribusion signal into different frequency bands. The main essence of the work is the design and realization of Alfa Monitor – a device for relaxation , that for implamanting EEG biofeedback uses acoustic form and sensing of electrical activity of brain in the region of alpha waves. The second half of the work is t focused on circuit design, using integrated circuits with component values of relevant calculations . Further, it analyzes the practical implementation of alfa monitor. The last chapter is devoted to the testing the functionality of this device.

The neuropsychological correlates of emotions
TESAŘ, Michael
The presented thesis deals with localization of emotions and its processing according to visual emotional stimuli from IAPS. It uses EEG analysis and non-parametric statistics Kruskal-Wallis ANOVA, Wilcoxon's t-test. Results confirm hemispherical asymmetry theories and it was found a new localization of the neutral emotion in the left frontal alpha EEG asymmetry, which is not clearly described by other authors. Processing of emotions shows that complex affective reaction of positive and negative emotions is not significantly resolved; reversely the biggest resolving is the first processing time exposition automatic affective reaction. Acquisitions of the thesis are providing crucial theoretical knowledge for further EEG and emotion research, describing localization of the neutral emotions in the frontal cortex and processing of emotions in affective reaction to visual stimulation.
