Abstract

According to many reports the amygdala plays a role in fear, attention and anxiety1. In addition to these emotional roles, the amygdala which is involved in the conditioning process projects to many anatomical areas to elicit physiological responses such as blood pressure elevation, skin conductance response and respiration as well as behavioral responses such as freezing and facial expression of fear. In an awake state, the amygadala evaluates a variety of environmental stimuli to determine whether the stimulation is harmful or safe; if it is harmful, the amygdala immediately elicits emotions of fear and anxiety simultaneously with physiological changes. In other words, measuring physiological responses could be an index to determine the level of emotion occurred in a situation.
