Electroencephalography
Jarošová, Veronika ; Ronzhina, Marina (referee) ; Chmelař, Milan (advisor)
This semestral paper has its aim to describe the electroencephalography. The beginning of paper is devoted to the history of electroencephalography, then there is both spontaneous and evoked brain activity described. Further, the paper deal with the electroencephalography. At the conclusion of teoretical part is described the methodology and processing of electroencephalography signal. The practical part of the work is focused on the creation of three various exercises on the epilepsy theme, reflexes and memory. Then the exercises were verified practically at fourteen volunteers. Further, in the work there is mentioned the instruction for particular measures, valuation results and its discussion.

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.

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.

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.

The use of computer programms in rehabilitation after head and brain injury
Plechatá, Adéla ; Kulišťák, Petr (advisor) ; Stehlík, Luděk (referee)
The theoretical part of the theses deals with options of the use of computer technologies in rehabilitation after head and brain injury. The introductory part outlines the topic of neuropsychological rehabilitation, its rudiments and major models. The following part contains a summary of benefits and disadvantages of computer-assisted rehabilitation and a short familiarization with studies considering efficiency of this approach in rehabilitation. Furthermore, this part contains a list of the most often used professional rehabilitation programms and their area of application. The third section follows up the topic of virtual reality and its advantages over simpler softwares. Moreover, there is also a summary of findings considering its efficiency. The last theoretical chapter describes principles and applications of EEG biofeedback therapy. Studies dealing with the efficiency of neurofeedback in rehabilitation after a traumatic brain injury are shortly mentioned at the end of this chapter. The practical part contains a propposed research project which deals with the effectiveness of neurofeedback in rehabilitation of deficits in attention, memory and executive functions of individuals after a traumatic brain injury. This is an experimental randomized controled study.

Neurofeedback and effectiveness of its therapeutic application
VOSPĚLOVÁ, Tereza
This theoretical bachelor thesis introduces neurofeedback, development of its research and its associated areas. It also deals with assessment of effectiveness of therapeutic use in the area of ADHD, epilepsy, specific learning difficulties, Autism Spectrum Disorders, anxiety disorders, OCD, depressive disorders, sleeping disorders, post-traumatic stress disorder and improving the performance. The assessment altogether involves 27 studies and 2 meta-analysis from several databases such as PubMed, Google Scholar, EBSCO, Sciencedirect, PsycNet and ResearchGate. Randomized controlled trials consisting of primal empiric data (except for 2 meta-analysis), which were published in English, Czech or Slovak language or their publishing is about to be done, were incorporated. According to the available results, it wasn't possible to affirm the highest level of the effectiveness, and the treatment using the neurofeedback is characterised as probably efficacious. The work summarizes many methodological imperfections found in examined sources and stresses the importance of their elimination for the future research, so it might be possible to find and prove specific influencing factors.

Utilization of EEG biofeetback in work with childern who suffers attention deficit disorder
Dvořáková, Anna ; Komárková, Tereza (advisor) ; Švandová, Martina (referee)
Subject of the thesis was focused on the utilization of EEG biofeedback for children with an Attention deficit disorder. The objective was to draw attention to one of the possible therapy methods for Attention deficit disorder and describe the EEG biofeedback in relation with it. The theoretical part addresses the attention disorders, their diagnostics, methods of treatment and the EEG biofeedback. The practical part describes use of the EEG biofeedback in work with children with the Attention deficit disorder through a qualitative research by means of in-depth semi-structured interviews. The interviews were handled from the viewpoint of a parent with a child having the attention disorder and from the view of a professional from a specialized institution. The results of the research on the examined cases show that this method of therapy may be effective not only in relation with the attention disorders, but it could also be used for other diagnosis.
