Behavioural processes
-
Aggression is a common agonistic behavior affecting social life and well-being of humans and animals. However, the underlying mechanisms of aggression remain poorly understood. For decades, studies of aggression have mostly focused on laboratory rodents. ⋯ Zebrafish demonstrate high genetic and physiological homology with mammals, fully sequenced genome, ease of husbandry and testing, as well as rich, robust behavioral repertoire. As zebrafish present overt aggressive behaviors, here we focus on their behavioral models and discuss their utility in probing aggression neurobiology and its genetic, pharmacological and environmental modulation. We argue that zebrafish-based models represent an excellent translational tool to understand aggressive behaviors and related pathobiological brain mechanisms.
