At the research center in Manchester, New Hampshire, scientists are monitoring levels of anxiety and post-traumatic stress disorder. They’ve found that people with post-traumatic stress disorder experience physical responses when reminded of the memory, including a raised heart rate and sweat. But it’s not just a memory to people like Johnny, they feel like they are actually reliving the event. The body will prepare to deal with the situation, unable to accept that the event is over, and always afraid of it repeating. Johnny has problems sleeping, and when he does, he wakes up crying. At a hospital in Boston, they figure out how fear is processed. After flashing photos of blank faces, with one image of a terrified face, the researchers saw a high response in one part of the brain. The amygdala controls threat and fear. When something possibly harmful happens to us, the amygdala quickly activates and sends output to the body. By tensing muscles, releasing hormones, and increasing blood pressure, the amygdala is doing what it can to help you survive. In a normally functioning brain, the amygdala will send a danger alert to the frontal cortex, which processes with reasoning whether or not the danger is real. However, in a brain with post-traumatic stress disorder, the frontal cortex’s thinking is overridden with emotion. This causes people to fear for their life in from even minor situations. The overly sensitive amygdala sets off a series of emotions, triggering the release of adrenaline in the body.
