Violence Sparks Aggression: Witnessing Aggression Activates the Brain for Aggressive Behavior
In a groundbreaking discovery, researchers from the Society for Neuroscience (SfN) have uncovered a neural mechanism that plays a significant role in aggression priming among males. The findings of this study will be published in the prestigious Journal of Neuroscience.
The research reveals that certain neurons in the medial amygala become highly active when male witnesses observe violent acts committed by their peers. This activation appears to prime these observers for increased aggression in the future, particularly if the attackers are familiar.
Interestingly, this neural response is not triggered when males observe unfamiliar attacks. The study further demonstrates that activating these neurons while males watch violent strangers promotes aggressive behaviour in the observers later, while artificially inhibiting these neurons suppresses later aggression.
The implications of this research are far-reaching. The findings suggest that not only proximity, but also familiarity of attackers may be risk factors for behaving violently later, at least in males. This neural mechanism could potentially inform the development of neural and behavioral treatment interventions for learned violence.
