Neurobiological Basis of Reactive Aggression: A Review

Reactive aggression is a response to salient threats that may have evolved as a strategy for survival. The likelihood of its outburst is mediated by several factors including the activity of serotonin and other neurotransmitters that regulate reactive aggression through the corticolimbic circuit. Specifically, this circuit is modulated by monoamine oxidase A (MAOA) such that low levels of activity incline an animal to impulsive behavior. Evidence also indicates that aggressive behavior is determined through interactions between genes and the environment. Further studies are expected for appropriate treatment
