Aggression & Cooperation Salvador Ayala and Joseph Nield

Aggression A range of behaviors that can result in both physical and psychological harm to oneself, other or objects in the environment.

Genetic and Neural influences on Agression A very complex social behavior that evolved in the context of defending or obtaining resources. The neural systems implicated by aggression are mostly the amygdala and the orbitofrontal cortex. Our genes may make our receptors of testosterone more or less sensitive causing more or less aggressive behaviors.

Biochemistry and Aggression Neurotransmitters involved are serotonin, testosterone, and cortisol. High levels of testosterone cause more aggression. Low levels of serotonin also are a cause of more aggressive behavior.
