“…Although cultural and social learning factors frequently preclude identifying the role of biological factors in the long-term consequences of stress in human studies, we have recently shown in rats that exposure to stress during the peripubertal period leads to abnormal social interactions at adulthood (M arquez et al, 2013); the same pattern of social alterations was found when stress was substituted by administration of the glucocorticoid stress hormone, corticosterone (Veenit et al, 2013). Specifically, peripubertally stressed rats showed reduced motivation to explore a juvenile conspecific versus an object in the threechambered test (M arquez et al, 2013), a task used in non-human primates and rodents (Bauman et al, 2013;Moy et al, 2004) that can be considered akin to social approach-avoidance tasks used in humans (Heuer et al, 2007;Roelofs et al, 2009). Particularly susceptible to the long-term effects of this form of peripubertal stress is the prefrontal cortex (M arquez et al, 2013), the engagement of which has been shown to be critically involved in social behaviors in humans (Dichter et al, 2009;Ho et al, 2012) and in animal models (Avale et al, 2011;Covington et al, 2010;Stack et al, 2010).…”
