<unk>  is the asymmetrical representation of<unk>  control and processing in the brain. There is evidence for the<unk>  of other brain functions as well. Emotions are complex and involve a variety of physical and cognitive responses, many of which are not well understood. The general purpose of emotions is to produce a specific response to a stimulus. Feelings are the conscious perception of emotions, and when an emotion occurs frequently or continuously this is called a mood. A variety of scientific studies have found<unk>  of emotions. FMRI and lesion studies have shown asymmetrical activation of brain regions while thinking of emotions, responding to extreme<unk>  stimuli, and viewing<unk>  situations. Processing and production of facial expressions also appear to be asymmetric in nature. Many theories of<unk>  have been proposed and some of those specific to emotions. Please keep in mind that most of the information in this article is theoretical and scientists are still trying to understand emotion and<unk> . Also, some of the evidence is contradictory. Many brain regions are interconnected and the input and output of any given region may come from and go to many different regions.
