Animal Models of Neurodevelopmental and Psychiatric diseases

Head of the department

RNDr. Tomáš Petrásek, Ph.D.

The research group of Animal Models of Neurodevelopmental and Psychiatric Disease is a recently established team of researchers, with the main focus on neurodevelopmental and psychiatric disease in animal models. It applies advances neurophysiological and behavioural tools and methods to investigate transgenic and drug-induced conditions mimicking neurological and psychiatric disorders, with the aim of elucidating their molecular and cellular mechanisms. The main focus of the group is on autism, schizophrenia and related mental disorders. A wide range of behavioural tests is applied to interrogate cognitive functions, emotionality, and social interactions in animal studies, along with in-depth analysis of underlying neurochemical and histopathological changes in the brain. An in-depth characterisation of the animal models is performed to define their validity and potential limitations. The ultimate goal is to elucidate the neurobiological mechanisms and define the behavioural correlates of neurodevelopmental diseases in experimental models in order to find new preventive schemes and therapeutic approaches.
