The role of parvalbumin interneurons in seizure initiation, propagation and termination in a mouse model of focal cortical dysplasia of type II
 Populová, Jana ; Řehořová, Monika (advisor) ; Kirdajová, Denisa (referee)
Focal cortical dysplasia is a structural and functional malformation of cortical development caused by mutations in mTOR signalling cascade that can result in pharmacoresistant epilepsy. Parvalbumin interneurons are probably the most important inhibition force in the brain that can help to stop epileptic seizures and it is possible that there are changes in function of these interneurons that are dependent on focal cortical dysplasia. This thesis had the aim to create a murine model of focal cortical dysplasia type II with labeled parvalbumin interneurons. This model was created by injecting plasmid with mutated mTOR gene during in utero electroporation. Cranial window implantation was then performed over created lesion together with calcium indicator injection for measuring neuronal activity under two-photon microscope. Our results confirm the same morphological characteristics as other studies has shown and also occurence of spontaneous seizures. We have shown statistically significant differences in size of pyramidal neurons depending on lesional or non-lesional position. For parvalbumin interneurons there was no such difference. Counting these two types of neurons in lesion and outside of lesion shown a trend towards reduced numbers in lesion, however it was not significant. Data from...

Causes of epilepsy due to disorders of cortical development of the brain
 Populová, Jana ; Řehořová, Monika (advisor) ; Růžička, Jiří (referee)
Malformation of cortical development are an important cause of childhood epilepsy. It is estimated that up to 40% of these cases are medication-resistant. Pathophysiological mechanisms involved in the development of epilepsy are unknown. Identification of new type of genes associated with MCD leads to development of new experimental models recapilute human clinical symptoms. Aim of this study is to summarize information on current progress in this area obtained from MCD experimental models. These informations will help us better understand epileptogenesis. Keywords: malformation of cortical development, epilepsy, focal cortical dysplasia, epileptogenesis
