Source analysis and comparation of Feldenkrais inspired movement and visual stimulation using sLORETA
Novotná, Tereza ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Title of thesis: Source analysis and comparation of Feldenkrais inspired movement and visual stimulation using sLORETA Objectives: The thesis aim is to evaluate intracerebral source activity during a simple arm movement inspired by Feldenkrais method and to compare it with a visual stimulation of the same movement presented in a clip and with an imagination of the same movement. The movement inspired by Feldenkrais method was simplified to a repeated flexion of the dominant arm. Source analysis was evaluated from EEG and processed using sLORETA program, Methods: To obtain the data, experimental group was put together containing 12 participants aged 22-60, (mean = 27.2), both genders included. Participants were subjected to one-off measurement by the EEG instrument. Feldenkrais inspired movement of a flexion of a dominant upper right arm was investigated. The experiment constisted of six parts: 1. native EEG record with eyes closed and open, 2. active flexion of the dominant upper arm with eyes closed, 3. active flexion of the dominant upper arm with eyes opened, 4. watching video presenting repeated upper arm flexion, 5. dominant upper arm flexion imagination with eyes closed. Every part lasted for two minutes. Between individuals parts was inserted a pause. Obtained EEG data were processed with...

Changes in central reactibility during thermal stimulation monitored by electromagnetic tomography (sLORETA)
Richtrová, Eva ; Pánek, David (advisor) ; Nováková, Tereza (referee)
Title: Changes in central reactivity during thermal stimulation monitored by electromagnetic tomography (sLORETA) Objectives: The objective of this thesis is to determine whether there are any changes in central reactivity during local thermal stimulation by heat and cold and to compare the effect of analgesic electrical stimulation by TENS (Transcutaneous Electrical Nerve Stimulation) applied after single thermal stimuli. The brain activity was scanned from the scalp EEG and the results were evaluated by using sLORETA program. Methods: Twelve young, healthy people over the age of 21 participated in this study. The requirement for the participation in this experiment was good health condition without any neurological or other diagnoses. The electrical activity of the brain was being recorded throughout the whole experiment using a 32-channel EEG cap. The measurement had multiple parts. During the whole experiment, the participants were lying on the therapeutic table and all stimuli were applied locally to the right hand. Firstly, the EEG was recorded while participants were resting with closed eyes for five minutes. Then we realized a measurement of a two-minute long application of electrical stimulation of TENS in above-threshold sensitive intensity, which was individual for each participant. The...

Brain activity assessment using sLORETA during modulated and physical activity.
Košťálová, Johana ; Pánek, David (advisor) ; Malá, Jitka (referee)
Title: Brain activity assessment using sLORETA during modulated and physical activity. Objectives: The aim of this thesis was to compare changes in the electrical activity of cortical and deep brain structures using sLORETA program between the resting state, active movement and passive observation of identical motion performed by the author of this thesis and the same one shown in the video. Methods: In this research participated 12 university students (8 women, 4 men). Age of subjects was between 23 and 25 years. The whole experiment consisted of five parts: 1. electroencephalography in supinated lying position with opened eyes, 2. watching a video, where the selected movement was performed by a woman, 3. watching a video, where this movement was performed by a man, 4. watching the author performing the same movement, 5. performing this movement by subjects themselves. Each of this parts lasted two minutes. The tested movement was 1. diagonal (flexion and extension pattern) of PNF method for right upper extremity. During the whole experiment was registered electric activity of the brain using a scalp EEG. Obtained EEG signal was afterwards exported to sLORETA program, which enabled us to see the collected data in 3D Talairach system and also to make a statistical assessment using a Student's...
