Pain and Panic: The Demons behind Biological Fear :: Biology Essays Research Papers

Pain and Panic The Demons behind Biological FearA variety of terms are used to describe fear. The Bible uses dustup like fear, afraid, terror, dread, anxious, tremble, shake, and quake over 850 times to portray this core charitable emotion. Healthcare professionals use terms like fear, anxiety, panic attack, and phobia to illumine the spectrum of our fears. (2) Our emotions are said to be the virtually subjective of all our biological components. It actualisems that we have a difficult time grasping them, and an even much difficult time controlling them. Fear seems to be one of the most challenging of our human emotions when it comes to trying to subdue it ourselves. When we see a offensive bug, or are caught off guard by an extremely gaudy noise, we jump before even thinking about it. It seems like a normal answer, and then after the initial surprise we can construe ourselves that we are still alive, everything is fine. But what about people who have anomalous reactions to fears? People who develop a phobia that is not so thriving to subdue?These questions can be partly answered by looking at what happens in the brain when we are afraid. In an experience of danger the amygdale, a small part of the brain located behind both ears, is alerted. In response to the frightening stimulus, the amygdale sends signals to the circulatory system. Blood pressure goes up, heart pace speeds up, and muscles tense. Doesnt this response sound a lot like what we can see on the Discovery Channel? When a lion attacks, we can at once see the antelope go into defense mode. So basically, our initial reaction to fears is no different than the basic souls of animals, an evolutionary response. (1) But waitanimals do not, or CAN not get afraid of the same things that humans can. And I am fairly certain an antelope cannot be diagnosed with an anxiety disorder. Animals, for instance, do not live in fear that they might fail a test, or lose their job. These fears that humans d evelop that are not simply instinct reactions deal with another part of the brain, the cortex. Humans can use cognitive reasoning to assess whether or not we should feel afraid. Charles Darwin posed the question, Does the reaction to fear precede the thought? (3) The answer is yes. In studies, it has been shown that pathways from the cortex to the amygdale are weaker than those that lead from the amygdale to the cortex.
