Disgust

Short answer: Imaging studies link the anterior insula to disgust. In one study, how strongly people felt disgust tracked anterior insula activity regardless of its form.

The insula isn't disgust-specific, though: it represents the body's internal (interoceptive) state in many emotions. A 2022 meta-analysis found that 'core' disgust (contamination) and 'social' disgust (moral) engage different networks but share anterior insula and fusiform activity. Occipital, amygdala and prefrontal regions are involved too.

Video transcript: Disgust: The Emotion Built to Keep Contamination Out

DID YOU KNOW? Disgust is driven by a neural system that detects potential sources of contamination, poisoning, or biological harm. The anterior insular cortex is especially important, integrating sensory information from taste, smell, and the internal state of the body, while the basal ganglia and amygdala contribute to avoidance and threat processing.

The write-up

The emotion built to keep contamination out. The anterior insula matters, but it isn't a disgust-only region.

  1. Exhibit A

    Feeling disgust

    In Harrison et al. (2010), how strongly people felt disgust correlated with anterior insula activity, whatever form the disgust took. This fits earlier findings for disgusting smells and for seeing disgusted faces.

  2. Exhibit B

    Seeing versus feeling

    Lesion and electrode studies suggest that recognizing disgust in others depends on a more ventral part of the insula. In Harrison's data, that ventral region responded when people observed disgust but not when they felt it.

  3. Exhibit C

    Core versus social

    A 2022 meta-analysis found that core disgust, about contamination, engaged threat-detection networks, while social disgust engaged social-cognition networks. Both shared anterior insula and fusiform activity.

  4. Exhibit D

    A wider network

    Across studies, disgust generally engaged occipital, insular, amygdala and prefrontal regions, not just the insula.

  5. Exhibit E

    The body's state

    The insula is thought to represent the body's internal, interoceptive state. Different kinds of disgust produce different bodily responses, which is part of why the insula responds in many emotions, not only disgust.
