The subcortical brain is the area of the brain that focuses on survival (TedxTalks). Long-term exposure to trauma inflicted on a person can negatively affect the subcortical brain.

Scientists observe war veterans for signs of post-traumatic stress disorder in attempt to explain this process. According to doctor John Rigg, a physiatrist who studies brain injury medicine, when a person has experienced trauma, they are prone to releasing stress hormones more regularly and reacting aggressively to potentially dangerous situations. On a battle field, this is helpful but, in society, the ‘fight or flight’ reaction may be

Various behavioral studies focusing on the memory functions of the hippocampus have demonstrated that moderate stress enhances memory performance but severe stress causes adaptive plasticity and impairs memory.
