Experimental modeling of mental disorders on animal helps both to reveal mechanisms of the appearance of pathology and to direct the ways of effective methods of its treatment. The goal of the present work was to create a new model of schizophrenia by oral Levodopa+Carbidopa (LC) administration. Introduction of LC to rats was found to induces a significant decrease of emotional reactions, hypersensitivity to sound stimuli, a reduction of exploratory activity, stereotype behavior, and motor hyperactivity in occasional rats. It is concluded that the LC administration to rats may be used as an alternative dopaminergic model of schizophrenia on animals.
