Rationality and emotion do not live in separate parts of the brain
A note for Lesson no. 1, "You Have One Brain (Not Three)," in Lisa Feldman Barrett.
Some context from page 16 is:
And rationality and emotion are not at war... they do not even live in separate parts of the brain.
This topic is a focus of my previous book, How Emotions are Made: The Secret Life of the Brain. A given instance of emotion, whether it's happiness, fear, or schadenfreude, is constructed by the whole brain via prediction, not by any so-called dedicated brain circuit. The same is true for thoughts, perceptions of the five senses, and any other mental function. No parts of the brain are dedicated to emotions, thoughts, or other cognitions.
