Automated monitoring of behaviour as a new paradigm in the research of depressive disorder
Revayová, Anna ; Valeš, Karel (advisor) ; Kubik-Zahorodna, Agnieszka (referee)
The rapid antidepressant effect of ketamine changed the direction of the research of potential antidepressants and its effect was also evaluated in this thesis. However, the main focus of this thesis is a new methodological approach to the research of depressive disorder. The main interest lies with the evaluation of automated monitoring of behaviour in this research. The first aim of this thesis was to evaluate the antidepressant effect of ketamine in the forced swimming test using software enabling automated monitoring of behaviour. The second aim was to meassure the change in phosphorylated Mammalian target of rapamycin (mTOR), using Enzyme-Linked ImmunoSorbent Assay (ELISA). The last, but the most important aim of this thesis was to implement the utilization of Phenotyper boxes in the automated behavioural evaluation of the olfactory bulbectomy model of depressive disorder and also evaluate the effect of ketamine in this model. Ketamine did not show an antidepressant effect in forced swimming test, however this observation could be influenced by chosen dose and mouse strain. Sensitivity of the test to chosen experimental protocol shows insufficient validity of this test. Observed change in level of phosphorylated mTOR corresponded with the behavioural results. Data collected from Phenotyper...

Forced swimming test and mechanisms of depression
Janďourková, Pavla ; Nekovářová, Tereza (advisor) ; Vodička, Martin (referee)
Depression is a severe psychical disorder belonging to affective disorders. Nowadays, it belongs to the most common psychical disorders and prevalence is between 5 % to 16 %. An animal research is essential to study mechanisms of depression. One of the models of the depression uses a forced swimming test in the animal research. Even though this test does not claim to model depression in all complexity, it has very predictive validity and mostly it is used to assess effects of antidepressant (on the basis of observation of changes in the behaviour of the experimental animals). The aim of this thesis is to review the neural mechanisms of depression and to compare them with mechanism which can be applied in the forced swimming test and affected by the antidepressants. Key words: forced swimming test, depression, neurotransmitters, antidepressants, hypothalamic-pituitary-adrenal axis
