Emotions And The Brain Essay

Everyone has emotions. Some people may have a lack of emotions but because of the hundreds of different emotions, everyone has at least a couple of emotions. Why do these emotions occur? How are they processed through the brain and then shown by our facial expressions or the way we hold our bodies? Our brains are made to watch for threats and rewards (Emotions and the Brain). When either one is detected the feeling region of the brain alerts the body through the release of chemical messages. Emotions are the product of these chemical messages. The emotion that someone may feel depends on the kind of chemical that is released. These chemicals aren’t the only thing that can produce an emotion. Your thoughts also contribute to the emotions a person may feel. There can also be problems with the way emotions are measured. Some examples of this are self-reports, behavioral observations, and physiological measures.
If someone tried to rob you would release stress hormones such as adrenaline or cortisol. These chemicals produce a flight or fight response. On the other side, if someone gave you a birthday present your brain may release dopamine, oxytocin, or serotonin (Emotions and the Brain). Your emotions, however, don’t solely rely on these chemical messages. Your thoughts can also come into play when expressing an emotion. In some situations the chemical message reaction time is so fast your feelings may take over your brain before you have time to think. An example of this would be a surprise party. When you walk into the party and you are surprised a big smile may come onto your face. This smile comes without thought and is the product of chemical messages being released from your brain. An example of changing the way you feel by the way you think would be if a person was about to perform a song and they started to think that everyone would hate the performance then that person would feel shy, upset, or nervous.
Emotions are part of everyday life and seem very simple. When something bad happens a person will feel upset and when something good happens a person will be happy. Even small events, like eating, can change the way you feel. For example when people skip meals they begin to feel tired, agitated, and anxious to eat more food. Part of this is because the chemicals inside of the human body. All of the organelles, cells, and organs in the human body need something specific to survive. Whether it is oxygen, water, or proteins, they need something. When a person skips a meal the organs in the human body begin to crave more food (Kalat, 401). This can also produce an emotion. If your stomach hurts then you will feel upset. Emotions don’t always come from an outside source. They aren’t always a reaction to something else. They can simply be a reaction to yourself or your own body.
Research depends very much on good measurement and measuring emotions is difficult. There are three main...
