Name: Electrical cerebral activity changes during targeted emotional stimulation, evaluated by sLORETA Goals: The main goal of this thesis is the comparison of electrical brain activity changes during targeted emotional stimulation. Method: The research was conducted by measuring electrical cerebral activity using Natus Neurology 32-channel Nicolet™EEG Wireless Amplifier 32/64 device. The activity measurements were taken by an EEG Electro-cap with a total of 19 flat registration electrodes (Fp1, Fp2, F7, F3, Fz, F8, T5, T3, C3, Cz, C4, T4, T6, P3, Pz, 36 P4, O1, O2), placed in accord with the internationally used 10-20 system. The impendance resistance did not exceed 10 kΩ, with a sampling frequency of 512 Hz and a bandpass of 0,5-70 Hz. Resulting data was then processed using NeuroGuide programme. A 30s long, zero-artifact EEG section was then chosen to be exported to sLORETA programme. Probands were divided randomly into three research groups - positive, neutral and negative. Each proband was asked to pass the VVIQ imagination vividity questionnaire. In the next phase, each participant was asked to undergo a three week long imagination training programme, consisting of watching VR videos and targeted imaginations of walking, three times a week. While in the VR simulation, music and sound effect...

Visual experince as example and pattern in relation to the expansion and influence into human life
Nohejl, Jiří ; Czumalo, Vladimír (advisor) ; Vojtěchovský, Miroslav (referee)
The main theme of this dissertation is to define an image as a visual experience. The human interaction is described by the author himself as a perception of the image, which serves as an information unit that could be presented as a possibility, example and pattern for the individual. There is an emphasis on the process of perception itself and on the way of interaction of an individual emphasizing the context of social learning and imitation in this text. The analysis of the principles of this interaction leading into introduction of the partial interactive models covering these processes is formed by the essential plane. The structure of the thesis is divided into ten main chapters in which the author tries to introduce a category of perception, a definition of the image and imitation as a tool of cultural transmission, presentation of the units of this transmission, the process of the interaction itself and analogous example of the fundamental role that a person in this interaction holds. There are also three analogies of these roles, which refer to the anthropological universal interaction describing the man as a gatherer and hunter. Their main purpose is to illustrate the form of a human experience better. Finally, there are reflections on the topic above. The possibilities and results, which...
