Hard wired neural circuits in mice that govern aggression are strengthened following victories in aggressive encounters. Synapses in the hypothalamus show signs of LTP following aggression training.
Researchers have identified a novel neural circuit that detects male pheromone cues pertaining to inter-male aggression.
People report experiencing greater feelings of anger on days following disrupted sleep.
Soft drink consumption during early adolescence predicted more aggressive behavior later in teen years. Aggressive behavior at 13 also predicted increased soft drink consumption at age 16. Soft drink consumption at 13 predicted fewer depressive symptoms, but depressive symptoms did not predict soda consumption. Findings suggest reducing soda consumption during adolescence could help curb aggressive behaviors.
When the expression of the ER-alpha gene was blocked in white-throated sparrows, the level of aggression they exhibited decreased.
Compared to typically developing children, those with disruptive behavioral disorders, characterized by antisocial behaviors and aggression, had less gray matter in the amygdala and hippocampus.
Mouse study reveals "on-off switch" nerve cells for male mating and aggression in the amygdala. MPN signaling cells in the amygdala that communicate with the hypothalamus are associated with reproductive behavior, and VMHvL signaling cells play a critical role in aggression.
Using optogenetics, researchers were able to manipulate oxytocin producing cells in a highly precise manner. They discovered oxytocin can amplify aggression as well as social friendliness.
Strengthened amygdala pathways increase aggression in those who have experienced trauma. The findings could lead to new treatments for PTSD.
A six-year-long study reveals 90% of gamers do not play in a way that is harmful or causes long-term negative outcomes. 10% of gamers develop an addiction to video gaming. Those with video gaming addiction display higher levels of depression, aggression, anxiety, and cell phone addiction than their peers who play games but are not addicted.A six-year-long study reveals 90% of gamers do not play in a way that is harmful or causes long-term negative outcomes. 10% of gamers develop an addiction to video gaming.

Study shows how sex-determining genes can mediate courtship and aggressive behaviors in fruit flies. The findings demonstrate the complexity of the relationship between behavior and sex.
Male fruit flies fed a ketone supplemented diet expressed reduced levels of aggression following concussion than those who were not exposed to the dietary intervention.
