Exposure to intermittent episodes of social defeat stress can increase drug seeking and leads to intense drug taking in rats.This study investigated the consequences of repeated, intermittent social defeat stress on patterns ...

Aggressive interactions between conspecific animals have been used as a social stressor with ethological characteristics to study how social interactions can modulate animal's behavior. Here, a new protocol based on ...

Prolonged and heightened responses to stress are known factors that influence the development of mood disorders and cardiovascular diseases. Moreover, the coping strategies related to the experience of adverse events, i.e., ...

Chemical inhibition and nitrergic stimulation of the left and right medial prefrontal cortex (L and RmPFC), respectively, provoke anxiety in mice. Moreover, LmPFC inhibition immediately followed by a single social defeat ...

The aims of this thesis were to investigate behavioral and electrophysiological patterns associated to resilience and susceptibility to social stress in mice. For this, we used a chronic social defeat stress protocol ...
