Schizophrenia is a serious neuropsychiatric disease with a lifetime prevalence of 1% and it disrupts almost all mental functions. It manifests with many symptoms, which can be roughly classified into three main classes - positive, negative and cognitive dysfunctions. The psychosis, which can be often seen in schizophrenia, is a very serious problem that along with all other symptoms influences the patients' clinical status as well as quality of their life. As no direct causes or causal treatments for schizophrenia are known, scientist often focus on animal models of schizophrenia as tools for investigating mechanisms that can take a part in real disease and for seeking novel antipsychotics. This thesis aims at investigating two-week subchronic treatment with dizocilpine (MK-801), a non-competitive antagonist of NMDA receptors, in Wistar and Long-Evans rats aged 30 (PND 30) and 60 days (PND 60) at the onset of the treatment. Subsequently, long-term neurobehavioral consequences of this experimental psychosis were studied by testing rats at three behavioral tasks: the Elevated-plus maze (EPM), the Morris water maze (MWM) and active place avoidance on a rotating arena (Carousel). The Western blot method was used to determine post-mortem changes in expression of the NR1, NR2A and NR2B subunits of the...
