Summary
The profound shifts in perception during psychedelic states stem from a surprising change in brain communication. Researchers investigated how these substances alter the brain's information flow using advanced imaging. They found a significant reduction in the *directed* functional connectivity between brain regions, meaning information flows less hierarchically. This less constrained network fosters a more flexible and integrated brain state, potentially unlocking novel insights and therapeutic benefits.
