Spectral analysis of the EEG signal
Blatný, Michal ; Kozumplík, Jiří (referee) ; Hrozek, Jan (advisor)
Master’s thesis deal about electroencefalography, measurement EEG signals and analysis measuermed signals. Project contains two basis practical parts. Firts part contain two PC’s programs that’s are used to fundamental analysis to frequence-domain and visual display of brain mapping created with Matlab. Second chapter of practical parts includes two PC’s programs created with LabView. First of them is the EEG biofeedback making use for advanced analyses and second program is used to detection segment of stacionarity.

Psychogalvanometric measurement and biofeedback
Paulasová, Lenka ; Čmiel, Vratislav (referee) ; Hrozek, Jan (advisor)
This work deals with bio-feedback and the possibility of measuring changes in skin resistance for biofeedback. The Theoretic part is focused on the principle of biofeedback and its use. Next deals with the resistance of the skin, the changes depending on the emotions and the measurement this change . The practical part is devoted to the creation program for the use of skin resistance to change biofeedback in LabVIEW.

Alpha activity monitor
Kašpar, Blahoslav ; Sekora, Jiří (referee) ; Chmelař, Milan (advisor)
This work deals with problems of EEG biofeedback and possibilities of its use in therapy. The method of EEG biofeedback helps patients to achieve the state of relaxation. It is a noninvasive treatment modality. The paper also discussed the requirements for each component unit. The main point of a design and construction of Alpha activity monitor, a device implementing EEG biofeedback focused on sensing electrical activity of the brain, specifically alpha waves. Alpha activity is specific and their parameters are taken into account when selecting components and construction equipment. Custom feedback is then for the appearance of alpha activity mediated by the headphones in acoustic form. The work also includes design of electrical circuits and electrical diagram of the overall apparatus including a list of used parts. Electrical diagrams are formed in the EAGLE 6.1.0.

Audiovisual stimulator
Bartoš, Michal ; Čech, Petr (referee) ; Hrozek, Jan (advisor)
The main objective of this study is to learn about the audiovisual stimulator and to create hardware resolution of stimulation LED glasses and in environment of the program LabView application, which operate this stimulation LED glasses and in the same time create sound of stimulation. Use environment of the program LabView. Application, which is create in environment of the program LabView, enable operate stimulation LED glasses and arrange sound from three source with two different method, which use modern AVS. Application contains a lot of security, informative and agreement components.

Continuous breath monitoring
Sláma, Štěpán ; Sekora, Jiří (referee) ; Kolářová, Jana (advisor)
The purpose of this work is to get informations about the use of biofeedback, the physiology of breath and also about the investigation methods which is the physiology of breath evaluated by. The practical part is focused on creation of an application design with the use of biofeedback and measurement of pilot data. In this part implementation of the application is also done by training of the correct breath wave using biofeedback.

Alpha monitor
Prudil, Pavel ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
This master‘s thesis presents the problems of EEG bio-feedback and its application for relaxing a person. It deals with the requirements of the sensing electrode and the biological signal amplifiers. The main substance of my thesis is the proposal of Alpha monitor, a device that uses the electrical activity of alpha brain waves for the realization of biological EEG feedback. The device concept takes into consideration the requirements of users’ security and also characteristics of alpha activity, which define the requirements for signal processing circuits and for propositions of the aural transducer. This master‘s thesis analyses given submission, proposes particular circuits, presents the overall electrical diagram and the list of components. The overall electrical diagram and single circuits are drawn within the EAGLE 5.7.0.

ECG Biofeedback
Macková, Pavlína ; Kolářová, Jana (referee) ; Sekora, Jiří (advisor)
The master’s thesis is focused on the possibilities of measuring heart rate of ECG signal and its use in therapeutic game of ECG biofeedback. This thesis describes the way of measuring ECG with acquisition unit Biopac and analyzes signal processing for measurement of heart rate – algorithms of QRS detection, HRV analysis. Realisation of therapeutic is designed for applications in Matlab.

EEG Biofeedback Application
Zapletal, Jakub ; Drahanský, Martin (referee) ; Tinka, Jan (advisor)
Tato práce je shrnutím existujících přístupů pro zpracování EEG signálu za účelem EEG biofeedbacku a dále popisuje návrh a implementaci vlastní aplikace pro EEG biofeedback se zaměřením na trénink pozornosti. Dále obsahuje případovou studii provedenou na neurotypickém studentovi a studentovi s ADHD, která zkoumá vliv implementované aplikace na měřený EEG signál subjektů.
