Elektromagnetic field mapping in tissue
Port, Martin ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
This thesis is an introduction to the modeling of electromagnetic fields in the tissue and is focused on the knowledge of electromagnetic field theory. Maxwell's equations and their solutions are described the spread of plane waves in the environment. It also discusses the exposure limit values of specific absorbed power and hygienic limits based on the standards in force in the Czech Republic on health protection against nonionizing radiation in accordance with Government Regulation No. 106/2010 Coll. It also deals with the software interface in COMSOL Multiphysics 4.2 for solving physical modeling and simulation. There is mention of the RF module, which is used for modeling. Work mentions in detail about the menu of the program and the most important part - the Model Builder.

Stimulant drugs and their physiological effects
Nováková, Pavlína ; Novotný, Jiří (advisor) ; Hejnová, Lucie (referee)
The category of stimulant drugs is a heterogenous group of substances which benefit-to-harm ratio varies widely. This work attempts to use a systemic approach in order to characterize the underlying basis of the physiological effects of their selected representatives in brain. A brief pharmacological description of caffeine, nicotine, cocaine, amphetamine and methamphetamine is followed by an identification of main molecular targets of these drugs in the context of respective neurotransmitter systems. Major attention is given to both acute and chronic molecular mechnisms of action of the selected stimulant drugs up to the level of selected relevant neural circuits. In the next section stimulant drugs are presented as Trojan horses that attack the motivational system of the brain. Initially, a theoretical analysis of reward together with a neuroanatomical dissection of reward-related circuitry serves as a basis for the formulation of contemporary theories of drug addiction. Finally, an effort is made to synthesize common molecular events with specific aspects of reward in order to draw a picture of the neurobiological view of addiction.
