Functional MRI experiments have revealed that the anterior insula in the brain is particularly active when experiencing disgust, when being exposed to offensive tastes, and when viewing facial expressions of disgust.[31] The research has supported that there are independent neural systems in the brain, each handling a specific basic emotion.[4] Specifically, f-MRI studies have provided evidence for the activation of the insula in disgust recognition, as well as visceral changes in disgust reactions such as the feeling of nausea.[4] The importance of disgust recognition and the visceral reaction of "feeling disgusted" is evident when considering the survival of organisms, and the evolutionary benefit of avoiding contamination.[4]	./cache/en-wikipedia-org-3477.html	./txt/en-wikipedia-org-3477.txt
