Measuring electrical brain activity during stimulation of trigger zones from concept of Vojta principle
Martínek, Milan ; Pánek, David (advisor) ; Pavlů, Dagmar (referee)
Title: Measuring electrical brain activity during stimulation of trigger zones from concept of Vojta principle Objectives: The aim of this study is to clarify whether there is a change in the electrical brain activity evaluated by the sLORETA program during the stimulation of trigger zones according to the Vojta concept. The source activity during stimulation of trigger zones was scanned from the scalp EEG and compared with the sLORETA program with the source activity measured at rest, before and after the stimulation of the trigger zones. Methods: The research was conducted on 11 healthy adult subjects. The entire research group is consisted of women aged in range 19-32. The data was obtained from the scalp EEG before, during and after stimulation of trigger zones according to Vojta concept. For each proband the measurement of resting EEG with both open and closed eyes (2 x 10 minutes) was first performed, then the measurements were taken during the stimulation of trigger zones with open and closed eyes (2 x 15 minutes). Finally, a resting EEG was measured, alternating open and closed eyes after five minutes (4 x 5 minutes). There was a pause of at least 15 minutes between each stimulation of trigger zones. The order of open and closed eyes during resting EEG and during stimulation of trigger...

Default Mode Network: Ontogeny
Jarmar, Jiří Kryštof ; Nekovářová, Tereza (advisor) ; Moravcová, Simona (referee)
Default mode network is a functional network system in a brain, comprising of other sub- components. It is activated during tasks focused on the inner monologue, mentalization, episodical memory or self-reflection. The DMN activity is generally described as default mode functioning of the brain in absence of external stimuli, on the other hand its activity is inhibited during the presence of it. This thesis focuses on the main factors and changes that occur during ontogeny of DMN from birth to adulthood, mainly in structural and functional connectivity and anticorrelation relationships with other brain networks. After a general characterization of DMN, the first part focuses on general characterization of functional brain networks and statistical methodology of measuring their relationships and maturity. It follows by the description of important events in brain development and identification of main anatomical regions of DMN. The most important part is the last one, which provides observations of comparative studies of DMN between children and adults. Here we describe main changes and trends in ontogeny of DMN. Key words: Default mode network, functional network, fMRI, ontogeny
