Seven Days of Silence Quieted the Brain's Inner Narrator, Study Finds

A seven-day residential silent retreat sharply reduced connectivity in the brain's default mode network—the self-talk hub—and boosted mystical experiences to levels usually associated with psilocybin, all without any drugs. The finding comes from an observational study and cannot prove causation or medical treatment claims, but suggests that simply removing external inputs and extending quiet can rewire self-talk networks.
