Human brain and its modeling
Zelenka, Pavel ; Koudelka, Vlastimil (referee) ; Raida, Zbyněk (advisor)
The project deals with the development of a computer model of human brain. The model is used in the simulation program CST STUDIO SUITE 2015 to show the distribution of electromagnetic waves. The outputs of simulations should help us with a better understanding of electromagnetic field behavior inside the brain. In real life, the model will be used for the verification of methods localizing source currents in the brain.

Brain Signals Visualization
Ševčík, Ivan ; Drahanský, Martin (referee) ; Košík, Michal (advisor)
EEG je neinvazivní metoda pro měření mozkové aktivity, která poskytuje důležitý náhled do činnosti lidského mozku. Tato práce prezentuje aplikaci, která slouží jako vizuálni nástroj pro analýzu EEG dat. Koncept aplikace je založen na jiných existujících řešeních, které byly v rámci práce analyzovány. Aplikace kombinuje prohlížeč signálů ve formě vícenásobného čárového grafu s 2D a 3D vizualizacemi užitečnými pro rozpoznání specifické mozkové aktivity. Součásti aplikace je i sada metod pro zpracování signálu. Závěr práce je věnován shrnutí dosažených výsledků a plánů pro další vývoj aplikace.

Method of Drawing on the right side of the brain from the perspective of art education
DAVIDOVÁ, Eliška
This bachelor thesis presents critical and comparative study devoted to the analytic method called Drawing on the right side of the brain and its comparison to traditional teaching models of drawing. The text is based primarily on an analysis of methodological materials by Betty Edwards (author of the book Learn to draw on the right side of the brain) and confronts them with the latest findings in neuroscience which are dealing with localization of creative acts. This thesis aims to critically point out the differences in the concept of teaching methods of drawing, their professional basis and to update their creative and learning potential for the sphere of art education.

Conscious and subconscious response of customer to marketing communication
Kovářová, Veronika ; Kincl, Tomáš (advisor) ; Novák, Michal (referee)
This Diploma Thesis analyzes the customer´s perception of the conscious and subconscious response. The goal is to find out how visual marketing communication affects consumers in the form of product placement appearing in the film in comparison between conscious and subconscious response. Respectively, whether the customer responds to some subconscious incentives and whether he is aware of this fact. The theoretical part describes the relatively new marketing direction Neuromarketing, its techniques, benefits and limitations. It also includes literary research describing the stimulation of the customer, specifically his subconscious, for the purpose of marketing success. This is complemented by ethical attitudes of experts. The next part describes the eye-tracking analysis, which is complemented by interviews. The results in the form of heat maps are supplemented by the knowledge gained from the personal interview and interpreted on the basis of the theoretical knowledge.

Some comments on frequency selective excitation in newly proposed MRSI sequences
Starčuk jr., Zenon ; Horký, Jaroslav ; Starčuk, Zenon ; Mlynárik, V. ; Gruber, S. ; Moser, E.
In many pathologies it is desirable to compare the metabolism inside a lesion, near the lesion, and in healthy tissue. The diagnostic value of MRS is enhanced by spectroscopic imaging (MRSI), permitting the simultaneous acquisition of spatially resolved spectra. In this way, assessing metabolic information about different brain regions within a single examination is possible. As with all in vivo spectroscopy, low signal-to-noise ratio (SNR) is the fundamental limiting factor in MRSI due to very low concentrations of metabolites of interest. Proton spectroscopic imaging, however, offers additional technical challenges as compared to single-voxel techniques, especially if acquisition of short echo time (TE<30 ms) is required. Critical to the success of proton MRSI studies of the human brain is the elimination of the very intense water and lipid signals arising from outside the volume of interest (VOI). Water suppression in MRSI can be very problematic in MRSI, in which the achievable degree of water suppression is limited by B.sub.0./sub. and B.sub.1./sub. inhomogeneities and water T.sub.1./sub. variations, invariably present throughout the larger VOIs. Suppression of liquid signals (from bone marrow and subcutaneous fat) is often severely complicated due to the fact that their relaxation behavior differs substantially from that of water. One of the basic approaches used to reduce the undesired contamination if the MRSI signals of interest consists in the use of the STEAM or PRESS selective excitation of the VOI. Both STEAM and PRESS techniques suffer from some drawbacks. STEAM reduces the sensitivity of measurement, PRESS has higher RF power requirements.
