 In the laboratory, the researchers exposed mice to a repeated session of unpredictable stressor (i.e.predator odor while restrained), and physical trauma in the form of inescapable foot-shock, and this was also combined with a mTBI.In this study, PTSD animals demonstrated recall of traumatic memories, anxiety, and an impaired social behavior, while animals subject to both mTBI and PTSD had a pattern of disinhibitory-like behavior.
