The brain is a building with a strict chain of command. At the ‘bottom’ are frontline workers – the regions that handle raw sensory input. At the ‘top’ are the parts responsible for abstract thought, memory, and our internal sense of self. Usually, these two groups don’t talk to each other directly.

For decades, people using psychedelics have described a feeling where the line between ‘me’ and the world vanishes. While it is clear these drugs cause intense shifts in vision and thought, scientists have struggled to pin down exactly what the brain is doing.
