The prefrontal cortex and amygdala are both involved in the regulation of aggression. The prefrontal cortex is important for executive function, impulse control, and decision-making, while the amygdala is responsible for emotion regulation, fear learning, and memory. Together, these two areas can help to regulate aggressive behavior, keeping it in check when it is not appropriate, and helping the individual control impulses and make decisions that are aligned with their internal values and goals.
