A specialized brain system may be required to recognize disgust on another person's face, and also to experience it firsthand.In the November issue of Nature Neuroscience, Calder et al. describe a patient shown by magnetic resonance imaging to have lesions in the insula and putamen, brain regions involved in taste and motor control, respectively.The patient could recognize happiness, fear, anger, sadness or surprise in facial expressions or in nonverbal sounds, and reacted normally to scenarios evoking anger or fear.He understood the concept of disgust intellectually and could correctly identify disgusting visual scenes.
