Evidence for a role of oxytocin receptors in the long-term establishment of dominance hierarchies

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana, Marjan Timmer

Exposure to stress can affect the establishment of dominance hierarchies. In our model, a social hierarchy established by two male rats during a first encounter is not maintained 1 week later. If one of the two rats is stressed, the stressed rat becomes su ...
