Ayawaska , a traditional drink used by South American shamans in rituals and folk remedies, is known to contain hallucinogenic DMT and 5-MeO-DMT .

A study group such as Christopher Timmerman, who works at the Psychedelic Research Center at Imperial College London , conducted an experiment in which 13 subjects received intravenous injections of saline containing DMT. During the experiment, subjects were asked to wear a hat with an electrode on their head and brain waves were measured. Of the 13 subjects, one moved violently and could not measure brain waves, so it was excluded from the experiment.
When Timmerman et al. Analyzed the subject's brain wave, the electrical activity of the brain of the subject who took DMT changed significantly, and a significant decrease in alpha waves detected mostly in the human brain when awake mainly Was accepted. On the other hand, delta waves that are frequently detected during non-REM sleep and theta waves that are detected from the cortex of the awakening brain have increased.
The following figure is the result of analyzing the brain waves of subjects who received DMT intravenous injection. The horizontal axis represents time and the vertical axis represents the frequency of brain waves. The closer the color is to yellow, the stronger the brain waves at that frequency. Looking at the part surrounded by a red frame for about 5 minutes after the start of the experiment, the brain wave of 8-15Hz representing the alpha wave is weak, while the delta wave of 0.1-3Hz and theta wave of 4-7Hz You can see that it is getting stronger. In addition, the red broken line in the figure represents the “subjective experience intensity” reported by the subject, and the time when the subject is experiencing a severe experience coincides with the time when the brain waves are changing drastically. You can see it.
“The same hallucinogenic agent, LSD and sirocibin , only weakens the whole brain wave, so the changes in brain activity caused by DMT seem to be different from other hallucinogens.”
Mr. Timmerman continued, “A sudden rhythm appeared at the timing when the change in the subject's brain activity was the most intense, suggesting that a certain order was born in the chaotic state. From these changes in brain activity and subject reports, subjects using DMT seem to experience a daydream that is clearer than their actual dreams while awake. ' Commented.
The illustration below is a sketch of the hallucinations seen by the test subject.
“The study using DMT has the potential to provide important insights into the relationship between brain activity and consciousness,” said Robin Carhart Harris, director of the Psychedelic Research Center, co-author of the paper. Is a small step in the first step, ”he said.
