Real-Time fMRI neurofeedback of amygdala activity
Sobotková, Marika ; Sekora, Jiří (referee) ; Lamoš, Martin (advisor)
The aim of this diploma thesis is real-time fMRI neurofeedback. In this case, the activity of amygdala is monitored and controled by an emotional regulatory visual task. A procedure to process measured data online and to incorporate it into the stimulus protocol has been proposed. A pilot study was carried out. Offline analysis of measured data was performed, including evaluation of the results of the analysis. The data is processed in MATLAB using the functions of the SPM library.

Audiostimulation
Sobotková, Marika ; Walek, Petr (referee) ; Sekora, Jiří (advisor)
The aim of this bachelor thesis is to design a device for audio stimulation, which will be used during examination with functional magnetic resonance. The next aim is to familiarize readers with magnetic resonance and stimulation. Whole device is controlled by microcontroller from open-source platform Arduino, model Due. Hardware is based on a non-soldering contact field. There is also draft of printed circuit board. Software is represented by flowcharts. Algorithm is designed and realized in wiring Arduino's library (which belongs to Arduino). Microcontroller is controlled by graphical user interface made by MATLAB.

Microcontroller Audiostimulation for Brain FMRI Examinations
Sobotková, Marika
During fMRI acquisition of task related data the variability of time lag between the audio stimulus demand and its actual playback causes a huge problem for precise data analysis. The lag is probably arised because of using standard PC for whole stimulation management, where is not possible to achieve absolute control of stimuli timing. The developed device for audio stimulation based on Arduino Due microcontroller solves that problem. The control of the audio stimuli playback is realized by external trigger. All together allows to avoid variable and high lag of audio stimulation.
