Anhedonia in the shadow of chronic social defeat stress, or When the experimental context matters [PDF]

, 2008
One of the core symptoms of major depression in human is anhedonia. For that reason, one of the main requirements towards experimental depression models is that they be able to demonstrate anhedonia in animals, that have been exposed to stressful events,
