The psychedelic 5-MeO-DMT alters brain activity in rats by increasing delta waves and decreasing theta waves in the hippocampus, changes that are not explained by movement. It also reduces slow and mid gamma power and disrupts theta phase modulation. The overall brain state resembles patterns seen during slow-wave sleep and REM sleep, suggesting that the drug's effects involve mixing waking behavior with sleep-like neural oscillations.
The psychedelic 5-MeO-DMT increases delta power and decreases theta power in the hippocampus of freely moving rats, effects not explained by changes in locomotion. It also dose-dependently reduces slow and mid gamma power and theta phase modulation. The overall spectral profile of awake behavior after 5-MeO-DMT resembles electrophysiological states seen during slow-wave sleep and REM sleep. These findings suggest that classical psychedelics may integrate waking behaviors with sleep-like neural activity patterns.
