This was an exceptionally good interview with psychology professor Lisa Feldman Barrett. The main point of her book How Emotions are Made is that that emotions are learned, not hardwired, and that they are part of the general mechanism of the brain as a whole, which is in essence to predict, not react. "Everyone has the same networks but the wiring is dependent on experience," says Feldman Barrett. "Anger, sadness are not universal. The way people make sense of sensations differ by culture."
