Neural correlates of the psychedelic state as determined by fMRI studies with DMT

Record summary

Timmermann and colleagues used fMRI and related measures to study acute intravenous DMT, a short-acting psychedelic associated with intense changes in perception, selfhood and scene-like experience. The study matters because its rapid time course permits close comparison between drug concentration, reported intensity and evolving brain-network changes. It does not verify claims about independent entities or alternate dimensions sometimes attached to DMT narratives.
