The insula is connected to the olfactory bulbs and is involved in the reaction to smells, such as the disgusting aroma of spoiled meat and unpleasant odors stemming from other people. The olfactory bulbs are part of the only sensory system in which stimuli from the external world are piped directly to the brain (including the amygdala) without first passing through the thalamus. As a result, smells such as those indicating spoiled meat and the presence of predators or other people have a particularly powerful influence on behavior. The insula has also been associated with moral disgust, and there is evidence that the brain responds to moral and physical disgust in similar ways (see Research Box 2.1) (Tybur, Lieberman, Kurzban, & DeScioli, 2013).
