Traumatic stress can cause aggression by strengthening two brain pathways involved in emotion, according to research recently published in Journal of Neuroscience. Targeting those pathways via deep brain stimulation may stymie aggression associated with post-traumatic stress disorder.
The consequences of traumatic stress linger long after the stress ends. People suffering from post-traumatic stress disorder often display heightened aggression, caused by unknown changes in the amygdala. An almond-shaped structure nestled deep inside the brain, the amygdala plays an essential role in emotion, social behaviors, and aggression.
