Description
Summary:Depression is one of the most prevalent psychiatric disorders with significant lifetime prevalence. The study of human depression is hindered by the relatively significant heterogeneity of this disorder. As a result of these heterogeneities, studies using a sound and representative animal model of depression are extremely valuable and, in general, provide important information regarding the neurochemical/biological changes occurring during depression and the subsequent treatment of its symptoms. In this review we concentrate on two solid rat models of depression: olfactory bulbectomized (OBX) rats and Flinders Sensitive Line (FSL) of rats. These two models were selected because they possess all three characteristics of a good animal model; face, predictive and constructive validities. We also emphasize the brain serotonergic system and we discuss the open field and forced swim test to assess behaviour. [PUBLICATION ABSTRACT]
