Did you ever ask yourself if why are you afraid of something? Do you know where it came from and why? Example of this are when you are in the outside around early in the morning and walking to a dark place. Then you feel that something is following you and your breathing goes up. Your heart is beating very fast because of what you feel and what you think. Then minutes later you look back and you see that it's just a cat walking behind you. There is no danger at all. But why do you react instantly to that situation? What is fear for us?
I have read an article entitled How scientist discovered the "fear center" of the brain by Robert T. Gonzalez from the website www.io9.com. He discussed about how does our brain process fear?
Fear is common to us. We can know if a person is afraid of something by their facial expressions, voice and their actions. But why do we react to something instantly? In our brain, many parts of it plays a role in the process of fear and the most important part of it is the amygdalae which is a pair of almond shaped clusters of neurons located in our medial temporal lobes. It detects whether there's a possible danger in a situation. This plays a necessary part in processing the signals of the brain to perceive and experience fear. A researcher named Lawrence Weiskrantz said that if we remove our amygdalae, it will lead to the disapperance of the fear. When the process of removing amygdalae is occuring, there's a possible that our fibers of passage that connects other region in our brain may damaged. Our amygdalae is responsible to receive the main inputs from our visual, somatosensory cortices and auditory, while the hypothalamus, that produce hormones are the primary output. The process would of how fear works is to join the threat by the sensory stimuli to the fight or flight response, beginning by the releasing of hormones activated by the amygdalae by the hypothalamus.
Gonzalez said to his article that "We can sense it in the voices and actions of our friends and loved ones, and even recognize it in the facial expressions of complete strangers." This is true because If I'm afraid of something that is currently happening, you can feel me if I'm afraid of something and that goes with you too, I can sense if your afraid of something by your voice and facial expression.
The next article I have read entitled Searching the Brain for the Roots of Fear by Joseph Ledoux from the website www.opinionator.blogs.nytimes.com discussed about the roots of our fears.
He said to his article that difference between anxiety and fear is important to us in the task of analyzing and curing of anxiety disorders that affects many people. Fear, for scientist is our negative emotion initiated by the existence of stimulus (response) that has likely to cause hurt and anxiety. Our anxiety is defined by unpredictablility. It is greatly expand by our ability to imagine what will happen next or in the future. With imagination, sometimes it helps us to have a good reaction of what will happen next and a possibility to make the impossible possible. This two things can sometimes helps us to manage our challenges in life.
Joseph Ledoux says that "Animal models are giving us new clues about how to treat problems of fear and anxiety in humans." Sometimes in our life, we are encountering animals that we most afraid of like snakes, dogs, rat and spiders. But this tells us how we can react or deal with this things can also helps us to face our fears besides animals in our life.
Fear is normal to us. Whatever our fears are, we must know how to face it and how to change it. This is just are thoughts. But if you know that fear is happening to you right know, you must stay calm to think and act to the situation.
