This episode I describe the neural mechanisms that activate and control aggressive states and behaviors and the role of hormones–estrogen and testosterone–in mediating violent and/or competitive aggression. I will also discuss tools that can be used in order to control the factors that are known to trigger aggression. These include sunlight, estrogen sensitivity and competition within social settings. I will discuss the effects of caffeine and alcohol on impulsive behavior and how nutrition and supplementation can be used for mood regulation and aggression.
