Delineating pain and fear engrams in the prefrontal cortex
Ludínová, Kristýna ; Zitko, Jan (advisor) ; Herink, Josef (referee)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Chemistry and Pharmaceutical Analysis Candidate: Kristýna Ludínova Supervisor: PharmDr. Jan Zitko, Ph.D. External supervisors: Dr. Manfred Oswald, Prof. Dr. Rohini Kuner Title of diploma thesis: Delineating Pain and Fear Engrams in the Prefrontal Cortex Pain is a complex process associated with activation of various brain centres. According to evidence of imaging studies in humans and rodents the medial prefrontal cortex (mPFC) ranks amongst the brain area consistently activated during painful perception. The mPFC circuits underlies functionally-distinct processes, such as pain, emotional response, decision-making, attention amongst others. However, the precise contribution of mPFC in pain related function remains to be unknown. The aim of the study was to delineate how pain and fear are manifested at the cellular level within the regions of PFC. By employing activity dependent neuronal labelling we tested if cellular ensembles activated in pain and fear behaviours within the mPFC are distinct. We investigated a potential use of activity-dependent DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) expression in order to test for the functional role of PFC ensembles in pain and fear behaviour.

Disruption of hippocampal-prefrontal connection in animal models of schizophrenia
Černotová, Daniela ; Svoboda, Jan (advisor) ; Moravcová, Simona (referee)
Schizophrenia is a heterogeneous mental disease that afflicts about 1% of population with no treatment available that would ameliorate all of its symptoms. The key structures affected in schizophrenia are the hippocampus and the prefrontal cortex. This work focuses on the interplay between these structures and on the monosynaptic hippocampal-prefrontal connection, the abnormal neural activity of which is the main cause of cognitive, positive and negative symptoms of schizophrenia. This work summarizes existing findings about both normal and impaired function of the hippocampal-prefrontal connection and provides an overview of animal models frequently used in research. Key words: hippocampus, prefrontal cortex, schizophrenia, interneuron, animal model

The influence of inflammatory cytokines on depressive disorders
Svobodová, Eva ; Bendová, Zdeňka (advisor) ; Krulová, Magdaléna (referee)
1 Abstract Depressive disorders are one of the three most frequent diseases causing disability of everyday life of humans. Its occurrence in the population is rapidly increasing. Etiology of depression is unclear, and the treatment usually only ameliorates its symptoms. In patients, there were identified signs not only of chronic stress, which has been associated with depression for quite a long time, but also signs of chronic inflammation in the body. This has led to focusing on proinflammatory cytokines and their connection to chronic stress and depressive symptomatology. We are also interested in the causal link between pro-inflammatory markers and stress that has not yet been unequivocally clarified. The aim of this study is to combine the knowledge about the influence of chronic stress on the development of depressive disorder gained from animal and human models. Additionally, to combine the knowledge of the effect of specific proinflammatory cytokines on the development of the depressive disorder and the change in brain structures morphology which may underlie the symptoms of this disease.

Executive function disorder in persons after traumatic craniocerebral injury
Sahula, Petr ; Kulišťák, Petr (advisor) ; Krámská, Lenka (referee)
This thesis is working with theoretical aspects of psychological construct called executive functions, integrative models and various cases from clinical practice. Second part is elaborating neuroanatomy of frontal lobes with main interest on functional systems of the prefrontal cortex. Third aspect of this thesis is introduction to the clinical perspectives of traumatic brain injury. The last section works with neurpsychological assessment including subchapter containing informations about most popular neuropsychological methods of executive function diagnostics.The practical part includes design of research from the field of diffuse axonal injury diagnostics. It suggests possible method of detecting this "silent" brain injury. Keywords: executive functions, prefrontal cortex, traumatic brain injury, neuropsychological assessment
