Answer:
Smaller hippocampus
Explanation:
In general, the hippocampus of individuals with post-traumatic stress disorder (PTSD) is smaller than the hippocampus in individuals without PTSD. The hippocampus is located on each temporal lobe of the brain and is responsible for the regulation of motivation, emotion, learning, and memory. Scientist report that stress reduces the size of the hippocampus and individuals with PTSD have smaller hippocampus and prolonged exposure to stress will damage the hippocampus.
