Unformatted sample text from the term paper:
Fear is one of the most primal of human emotions. Fear can manifest in a variety of ways and that manifestations
involves not one but many areas of the brain and the neurological system as a whole. The amygdala, that almond-shaped region of the brain in the medial temporal lobe
of humans and other higher vertebrates, plays an incredibly important role in mediating fear. The amygdale is where memories of fear and other human emotions are stored. It
is also plays a role in abnormal manifestations of fear such as panic attacks and anxiety disorders, disorders that some individuals suffer on a daily basis. The amygdale has, in
fact, even been associated with a genetic predisposition for anxiety and panic attacks. Our bodys reaction to fear, whether a normal or an abnormal reaction, is determined by both psychological
and physiological changes in the body, changes that are associated with a diversity of components of the neurological system. Like the rest
of the neurological system, the amygdala processes stimuli such as images, sounds and even smells. Certain of these stimuli are passed to its specialized nuclei, the cortical nucleus, the
centromedial nucleus, and the basolateral complex. These, in turn, process the stimuli and pass them on to hypothalamus and other regions of the brain and body. The result
is our outward manifestations of fear, the increased heart and beathing rates and perhaps even the inability to move that even normal individuals experience in relation to fear. When
those responses are unduly accentuated by what to most individuals would be a normal event with no or only a slight reaction of fear, we enter the realm of anxiety
