Neural correlates of the DMT experience as assessed via multivariate EEG
bioRxiv July 18, 2019 Christopher Timmermann, Leor Roseman, Michael Schartner et al. 4 citations preprint
Intravenous DMT, a fast-acting psychedelic, markedly alters human brain activity. Compared with a placebo, DMT reduced oscillatory power in alpha and beta brainwaves and increased spontaneous signal diversity. Time-referenced analyses linked changes in subjective experience to changes in brain activity. Emergence of delta and theta frequency oscillations correlated with the peak of the experience, particularly its eyes-closed visual component. These findings advance understanding of the neurobiological underpinnings of immersive states of consciousness.
