    Animal conflict: from neurons to behaviour

    		Date: 21st August PM
    Aggressive behavior is a major human social problem and, at the same time a basic behavioral mechanism that contributes to survival and reproductive success. Despite its major biological and social relevance, important aspects of this behavior and its neurobiological background are still poorly understood. Invited speakers will focus on the development and neural background of normal and abnormal forms of aggressive behavior, and on its relationship with stress, flight, and anxiety. They will outline the way in which single or repeated stressors tip the fight/flight balance, will discuss the relationship between stress hormone production and abnormal aggressiveness, will assess the age-related neurobiology of the stress-aggression relationship, and finally, will show how aggression suffered (exposure to a predator) affects anxiety on the long run.
