How to Change Your Mind: What the New Science of Psychedelics Teaches Us About Consciousness, Dying, Addiction, Depression, and Transcendence

by Michael Pollan

The PCC is believed to be the locus of the experiential or narrative self; it appears to generate the narratives that link what happens to us to our abiding sense of who we are. Brewer believes that this particular operation, when it goes awry, is at the root of several forms of mental suffering, including addiction. As Brewer explains it, activity in the PCC is correlated not so much with our thoughts and feelings as with “how we relate to our thoughts and feelings.” It is where we get “caught up in the push and pull of our experience.” (This has particular relevance for the addict: “It’s one thing to have cravings,” as Brewer points out, “but quite another to get caught up in your cravings.”) When we take something that happens to us personally? That’s the PCC doing its (egotistical) thing. To hear Brewer describe it is to suspect neuroscience might have at last found the address for the “But enough about you” center of the brain.
