Terror

Terrorism's Scientific Basis

Fear is a natural aspect of the human mind, and philosophers have often regarded it as one of the most powerful internal motivators of the human spirit. Despite our comprehensive understanding of what terrifies individuals and how fear can play havoc with a person's mental health, we have little understanding of how fear works in the human mind.

Modern science is still unaware of what chemical reactions occur in the brain when fear is activated, or what psychoactive medicine (if any) would be effective in reducing fear. There is still a lot of uncertainty about what biochemical signals the brain creates in response to fear if any are produced at all. The emergence of phobias is well-documented, while little is known about the physiological responses they elicit. To put it another way, we may understand what terrifies us and why, but we don't fully comprehend how it terrifies us. Researchers at the University of Michigan are working to overcome this seeming lack of understanding.

The variables that determine the formation of anxieties and phobias in the mind were the primary focus of the research team. There is some evidence that genetics has a role in the development of fear reactions, according to the study. Some people appear to be genetically inclined to be fearful of specific things, implying that some anxieties may be hereditary psychological qualities. Another sub-topic of this line of research is examining the complicated chemical responses that trauma creates, with a particular focus on the biochemical cocktail that leads to lifelong fear and the need for therapy. Although it is well acknowledged that trauma and extreme conditions can instil anxiety in a person, little is known about how the brain reacts to such events, which can have long-term psychological consequences.

The amygdala, a region of the brain, is linked to how people react to fear, but it is not the main culprit, according to the researchers. Aside from determining what chemical activates fear, the team is also working to determine which parts of the brain are active when the fear reaction is triggered. This, together with an understanding of the physiological processes that are elicited or involved, could lead to some beneficial mental health improvements. One possibility is the development of medications that are more suited to the treatment of phobias and unreasonable fears. The team is also interested in looking at the chemical produced by the brain in order to overcome fear. Analyzing and replicating this can clearly have a wide range of applications, including obvious medical and military applications.
