Accordingly, an animal model has been developed using exogenous CORT administration in rodents to mimic the pathophysiological changes associated with stressful events that can invoke depression-like behavior [6] and [9]. CORT-induced depression model has advantage over the stress models (such as restraint stress exposure) that it avoid the possibility of potential habituation effects and variation in HPA axis response to stress stimuli [10] and [11]. Previous reports have shown that repeated CORT administration develops depression-like behavior in mice during forced swim test (FST) [10].
