Document Summary
In psychology, an emotion is defined as being a behavior with the following three components: (1) a subjective thought and/ or experience with (2) accompanying patterns of neural activity and physical arousal and (3) an observable behavioural expression. The emotions we experience include a biological response. Each stage uses a distinct set of brain regions. The firing of one brain region to an emotional response will influence the patterns of firing associated with subsequent stages of that response. Later stages can also provide feedback to earlier stages, which allows you to modify your emotional response as you learn more about the situation. The brain can activate an emotional response within 150ms of identifying a potential threat. The purpose of this initial brain activity is to tag or highlight that stimulus so that it receives extra processing by brain structures at later stages of perception.
