Summary
Brain imaging reveals psychedelic states share neural patterns with creativity and vivid dreaming. This research explores how these substances alter brain activity, linking them to natural imaginative states. Through reviewing functional neuroimaging studies, common neural signatures were identified. Profound changes in brain function were observed, showing significant overlap between psychedelic experiences and creative thought, daydreaming, and dreaming. This offers exciting insights into the q-bio.nc of consciousness and human imagination.
Abstract
Humans have employed an incredible variety of plant-derived substances over the millennia in order to alter consciousness and perception. Among the innumerable narcotics, analgesics, 'ordeal' drugs, and other psychoactive substances discovered and used in ritualistic contexts by cultures around the world, one class in particular stands out not only for its radical psychological effects, but also for the highly charged political and legal atmosphere that has surrounded it since its widespread adoption about 50 years ago: so-called psychedelic substances. We review functional neuroimaging investigations of the neural correlates of the psychedelic experience, and highlight relationships with the psychological and neural bases of creativity, daydreaming, and dreaming.
