• “PTSD” means post traumatic stress disorder.
• PTSD is the feeling of stress and anxiety after a traumatic experience. 
• Hippocampus is the region of the brain associated with emotion, memory and the autonomic nervous system.
• Study identified PTSD prone persons to size of their hippocampal region.
• Study suggests that smaller size hippocampus is vulnerable as a heritable trait, and is correlated to an increased liability to PTSD.
• This observation is potentially significant to the assignment of military duties, and treatment of a person.
• Scientists use magnetic resonance imaging (MRI) to evaluate patients receiving baseline treatments- Prolonged Exposure (PE) for PTSD.
• The results show that patients responding to PE exposure has smaller hippocampal volume than non responders. 
• This observation is potentially significant to the assignment of military duties, and treatment of a person.
• However, the research is inconclusive to the causation between effects of smaller hippocampal volume and treatment.
