Entering the Amazon for Ayahuasca
47sThe mysterious and forbidden nature of traveling to a remote jungle for an ancient psychedelic drug immediately hooks viewers.
▶ Play ClipThe video follows Michael as he travels to a remote Amazonian retreat to experience ayahuasca, a psychedelic brew containing DMT. He undergoes two ceremonies and pre- and post-brain scans to study the drug's effects on the mind and brain, exploring concepts like ego dissolution and the default mode network.
The world's largest city inaccessible by road; only accessible by air or river. Michael heads up the Amazon to Refugio Altiplano to drink ayahuasca.
Ayahuasca contains DMT, a neurotransmitter in our brains, leading to spiritual experiences like oneness with the universe or ego death.
Psychedelics have been used for thousands of years by indigenous peoples for healing, not just recreation. They were banned in the US in 1970, halting human research.
Recent studies have resumed, showing psychedelics decrease brain activity in certain areas, leading to ego dissolution. This is linked to reduced activity in the default mode network.
Dr. Robin Carhart-Harris from Imperial College advises Michael to not make the experience emotional, but to sit with thoughts and not resist.
Flight to Lima, then 90-minute boat ride up the Amazon. The retreat is remote, providing a natural setting for the experience.
Michael meets José, the shaman, who says the medicine wants to make your life better regardless of cultural background.
DMT is normally broken down by enzymes, but ayahuasca includes a chemical inhibitor that allows effects to last up to four hours.
Mild effects: vivid imagination, slight nausea, but mostly controlled. Michael sees images like bamboo and trees, but they disappear when he focuses.
Stronger hallucinations: bright squares, Aztec-like pyramids, feeling of body covered in blocks. Michael panics but calms himself, experiencing ego dissolution briefly.
Michael describes loss of control over mind and body, feeling small and humble. He wishes he surrendered more fully but got a good taste of ego death.
Robin Carhart-Harris shows that brain activity became more complex after ayahuasca. The default mode network was compromised during the experience, then reset and became more integrated afterward.
Michael's insight score rose from 27 at baseline to 39 after low dose, and further after high dose, indicating increased self-reflection.
Michael's journey demonstrates that ayahuasca can induce profound changes in brain connectivity and self-perception, though the experience requires surrender. The study highlights the potential of psychedelics to enhance understanding of the mind.
"Title accurately reflects the video's content: a personal journey with ayahuasca, including ceremonies and scientific analysis."

04:38
What brain network is associated with ego dissolution?
The default mode network (DMN).
29:58
What did Michael's brain scans show after ayahuasca?

Ego Dissolution Explained
Key concept: describes the loss of self-identity and its link to decreased brain activity.
04:38Default Mode Network Reset
Scientific finding: ayahuasca compromises the DMN during experience, then resets it more integrated.
29:58Insight Score Increase
Quantitative evidence: Michael's insight score rose from 27 to 39 after low dose, showing increased self-reflection.
31:11Personal Experience of Ego Dissolution
First-hand account of panic and surrender during the high-dose ceremony.
25:14[00:26] the world's largest city inaccessible by road. The only way in and out is by air or by river, I'm about to head up the Amazon to a remote jungle retreat
[00:40] called Refugio Altiplano, the Refuge on the Higher Plain. to drink an ancient psychedelic drug, ayahuasca.
[00:57] Ayahuasca contains dimethyltryptamine, DMT, a neurotransmitter in our brains. leads to what many describe as spiritual experiences--
[01:13] a sense of oneness with the universe, even a sense of one's self dying. doesn't really seem relevant to scientific inquiry.
[01:26] However an understanding of the human mind everything the brain is capable of. What does it mean to feel at one with the universe?
[01:42] This isn't about having fun or taking a risk I want to learn what my mind is capable of.
[01:54] [theme music playing]
[02:16] that are structurally similar to neurotransmitters When we ingest them, they bind to receptors in ways we're still trying to understand.
[02:32] they think about people challenging societal norms to a particularly narrow slice of human history and culture.
[02:45] Fossil records, cave drawings, and archaeological digs have been using psychedelic compounds for thousands of years, and by "used," I don't just mean
[02:57] For instance, among the indigenous peoples of the Amazon rainforest, psychedelics were and, and totally mainstream experience.
[03:12] As a member of these groups, believing psychedelics can heal, is not some weird or New Age idea. But when psychedelics became associated
[03:27] the United States banned research on them in 1970. From then on, testing on humans was essentially gone,
[03:40] and a few researchers have started in what some have described as a psychedelic renaissance. comprehensive studies on the beneficial effects
[03:55] By approaching psychedelics scientifically, our understanding of the human mind.
[04:11] When I go to Peru, I will be accompanied British researchers in over 40 years on the human mind.
[04:26] don't increase brain activity, as previously thought. Instead, they decrease activity in certain areas. the greater the reported feelings
[04:38] of what is called ego dissolution or ego death. It's the part that separates you from everything else,
[04:50] and your story in it. and feelings don't cease like when you're unconscious. and all that's left is naked perception.
[05:09] that I find difficult to wrap my head around, an extremely frightening experience, one that makes them feel more connected
[05:23] Now, I knew that I might feel ego dissolution on ayahuasca, I decided to speak to some experts.
[05:35] from Imperial College, London, to meet with me. that anyone has scanned a healthy person's brain
[05:48] with FMRI before and after ayahuasca. -Yeah. -It's quite pioneering work, really. -Yeah. -I've heard you should know why
[06:01] Yeah, I would suggest that you think To make it emotional is a lot more frightening to me. and I don't want to ruin that, right?
[06:17] I don't want to drink ayahuasca and then think, "Oh, my gosh, or I don't show my wife I appreciate her enough, There's something to be said for sitting with those thoughts,
[06:32] And in so doing, they become less of a threat. All of a sudden, they reveal things to you, and their scariness seems to dissipate.
[06:47] by people who are all filming me, you know? Yeah, the most important thing is that intention to go in. You don't resist.
[07:02] while I'm on the trip. to be done in order to measure brain activity, and physiological changes to my brain.
[07:15] with functional magnetic resonance imaging, or FMRI. and how different parts connect and talk to one another. before his experience with ayahuasca
[07:31] I expect to see that one network of the brain will become more strongly connected after the ayahuasca.
[07:46] I still felt some trepidation about my trip, it was time to set off for Peru.
[07:58] involved a flight to Lima, Peru, followed by a 90-minute boat ride up the Amazon River.
[08:12] And every minute I got closer meant that it would be harder to turn back. The Refugio Altiplano retreat is in a very remote area
[08:24] and I thought it would be a great setting So, Kelly, what does the word "ayahuasca" mean? Ayahuasca's been used for possibly over 4,000 years
[08:42] plant medicine for healing in the villages. I met with José, the shaman who would be
[08:55] -Hola, José, Claudia. -Hola, amigo. [speaking Spanish] Welcome to Refugio Altiplano,
[09:10] José, how do you feel about someone like me coming in, who is not part of your culture, taking part in it [speaking Spanish]
[09:25] and for the medicine, it makes no difference. This medicine, all it wants is to make your life better we give them a very small medicinal dose
[09:39] to the medicine, and then tomorrow night, [Michael] It was great to speak with José I am nervous about the emotional part of it,
[09:53] like I've been disconnected from the real world. since its illegal status in many countries
[10:07] is dimethyltryptamine, or DMT, which is a hallucinogen DMT can create psychoactive effects
[10:21] But normally, DMT is broken down rapidly by enzymes in the brain. but ayahuasca is actually a brew made from two plants.
[10:33] and the second contains a chemical inhibitor allowing the effects to last as long as four hours.
[10:46] to compare how I change during this experience. and you're drinking ayahuasca, it has authenticity
[10:58] when you give psychedelics in the laboratory environment. after you drink ayahuasca, we need a control condition,
[11:10] a short list of questions about your journey here, on a scale here. and zero will be strongly disagree.
[11:27] to this retreat center about how past events -I got ideas areas during... -Two.
[11:40] With different psychedelic drugs to ayahuasca we've found some quite consistent changes We've seen that the brain activity
[11:55] Of course, we can't wheel an MRI scanner is pretty much the best possibility that we have to do this.
[12:10] to protect me from bad spirits during the ceremony. I didn't believe in such things, but I was glad to do it because it was a symbol of José's good intentions.
[12:38] [Michael] The initial smaller-dose ceremony with the effects beginning after 30 minutes. [José speaking Spanish]
[12:53] We'll begin with our ceremony tonight, asking God to guide us, to give us knowledge and intelligence. [Claudia] We're going to bless the medicine first.
[13:05] [music playing]
[13:22] Gracias. Maybe also a bit like fennel or something.
[13:38] I'd never tasted anything like it. It was the most nervous I would be all night. DMT from the ayahuasca was flowing
[13:51] [José chanting]
[14:04] or chants, which were meant to guide me [chanting continues]
[14:32] [José chanting] The effects began slowly and were mild.
[14:44] were swinging like a cradle. but it made me feel sick My imagination was more vivid.
[14:57] but almost always under my control.
[15:09] I was comforted by this because it was a sign Thank you, José.
[15:21] was surprised by something that I saw. like bamboo that had been cut so that it was at a slant,
[15:34] -But as soon as I did, it was gone. -Mm-hmm. is to kind of create a sort of chaos in the cortex. The second time I was like, "Oh, yeah, nature,"
[15:52] And I imagined trees, but only in this ring. and they were all right here in my head. I didn't intend for that to happen.
[16:09] if you, in a sober state of mind, just imagine something, Okay, now an image probably popped into your mind, If I asked you a specific question like,
[16:24] and then, like, basically fill in that detail. those details were already in these--
[16:36] They seemed only as real as an imagined image, but they came with more detail, and a few times-- things appeared that I did not feel like I had put there.
[16:54] But as soon as I was aware of that, they disappeared. Yeah, let's do that.
[17:10] my head was clearer, and I wanted to discuss -Hola, Michael. -Hola. You had a perfect introduction ceremony.
[17:23] the only sort of revelations I had than I needed to be beforehand and now I'm not as dominated
[17:37] I'm just kind of in this moment right now. Like, I feel much more open to mystical thinking. He recommends that you complete with more medicine tonight
[17:53] the insight into yourself. [speaking Spanish] Three-quarters. Okay.
[18:05] I experienced this But I'm fascinated by how I want it to have meaning.
[18:17] I feel like I didn't hit that oneness yet. [Robin] Michael's getting the higher dose tonight, and the experience is very likely to differ
[18:29] quite substantially from the dose that he had last night. I know that that's a big part of ayahuasca I'm open to it, for sure, but I do feel still
[18:46] some apprehension for a larger dose tonight. I'm here to pick you up for ceremony.
[19:07] -Buenas noches. -Buenas noches.
[19:26] was expected to last four hours with stronger and more vivid hallucinations. José smoked a cigar made of a tobacco plant
[19:41] that's indigenous to the Amazon called mapacho. and remove negativity from the ceremonial lodge. [exhales slowly]
[19:54] The second ceremony included another shaman, Daniel.
[20:07] [chanting]
[20:22] bright squares, like, stacked like Aztec pyramids, through these, like, repeating kind of, you know,
[20:36] I mean, too many things to really describe, music notes and colors and shapes and squares. this is going faster and faster, and this is too fast,
[20:49] and then I felt my body being covered with these blocks, and I, like, saw my body from above [José chanting]
[21:02] and I said, "Mm, this was very bad. This is not good." so loudly I couldn't ignore them.
[21:16] And I had to come up with ways to console myself and have a complete breakdown and panic attack.
[21:28] and I successfully brought myself back I'm not going to die, and everyone here can help me."
[21:47] They didn't feel like they were under my control. A note from the song would occur, because I wasn't-- I was, like, on a ride
[22:03] [distorted chanting]
[22:18] -I can do the EEG now. -Yeah, sure. about having to do these tests with Robin. and Robin talking to me and asking me questions,
[22:36] the more I realized it was just about me. "I'm here to do a show. We're filming this. Everyone will be happier if I do it.
[22:51] and that gave me the courage to do it. So being less selfish [Robin] Each time I read an item, if you could give me a number
[23:06] according to how you see yourself at this moment, okay? "I see myself right now as extroverted, enthusiastic." Okay.
[23:21] and on his pre-ayahuasca answer, "Extroverted, enthusiastic." [Robin] But now I'm seeing signs of withdrawal
[23:36] "I see myself right now as critical, quarrelsome." two.
[23:49] "I see myself right now as critical, quarrelsome." [Robin] The experience has led to a change It's in a way reflective
[24:03] [plucks notes] and it's only halfway through the ceremony.
[24:19] [Daniel singing in native language] spoken by only 5,000 people in the world.
[24:35] in explaining what it felt like It's a different state of mind, anger to someone who has never felt it
[24:50] [singing continues]
[25:14] [chuckles] I'd say about five minutes into that first song... really panicked.
[25:29] to make sure it wasn't beating as fast as I thought it was. or something near it before I stopped.
[25:41] Michael is describing what to me sounds like quintessential ego dissolution, the start of it, that his control over his mind and his body
[25:58] and he felt some resistance to that. My feeling is that the intensity of his experience
[26:11] transformative type experience. [Michael] I was there in that ego-dissolving state I wish I was able to surrender more fully,
[26:27] but I definitely got a good taste of it. So the dosage last night was much higher.
[26:42] Visions-- the visuals were really vivid, and the feeling of strangeness was really strong. I'd be curious to know what José was doing last night.
[26:57] What plants did he call forth and why? He knew you were going through an intense ceremony. But he said he was very happy because he knew
[27:13] I'm really interested in what the lessons were. I felt so small... and so humble. But-- but, honestly, I liked it. I wasn't afraid of it.
[27:29] I was glad to be reminded that I'm weak. everything I'm concerned about way above what would be
[27:42] But that made my fear and anxiety big enough The question is will I remember to apply that, Before leaving Peru,
[27:56] I'll place this on your head. after my higher dose of ayahuasca. I can't wait to see you back in L.A.
[28:10] [Robin] Being here in the jungle, it's more organic. Because of that, I feel that I've collected data and meaningful about how psychedelics
[28:25] and ayahuasca specifically work on the mind and the brain. I had my second MRI so that Robin could see
[28:40] Although my ego dissolved only for a brief few moments, and I was anxious to see what it looked like in my brain.
[29:00] Robin, welcome to my home. Thank you for coming back. -Yeah. -How did ayahuasca affect my brain? Okay, so we found something quite interesting.
[29:14] We found that your brain activity became more complex, under the ayahuasca than at baseline. in terms of how I experience things?
[29:30] Mm, I think we can understand it in terms of the richness of your imagination, of your ideas. more changeable, more dynamic.
[29:45] All right, you looked not just at my brain -Yeah. -What did you notice there? called the default mode network that seems to relate
[29:58] We've seen in other studies that network is dramatically compromised. that process relates quite strongly
[30:12] to people's ego dissolution, and yet after the experience, or a kind of rebooting of the network, as predicted, was that your brain reset.
[30:26] more integrated, more strongly connected within itself. much more interested -Yeah. -You asked me a lot of questions
[30:42] about my insight into experiences. Well, actually we saw something really nice in those data. the lower dose and then the higher dose with ayahuasca,
[30:58] what we saw was that there was a graded increase Your score at baseline was 27. After the low-dose experience, it was 39.
[31:11] Wow, I definitely felt like the larger -and learned about myself. -Yeah. to do such a, you know, in-the-environment-type study.
[31:27] I really appreciate it, and I hope that I helped. and I've learned a lot.
[31:39] I feel like my experience with ayahuasca Instead of surrendering myself to its effects, and I told myself, "It'll be all right.
[31:52] but I should've just gone in and through. that relinquishing control and selfishness can make it vanish, but perhaps in doing so,
[32:06] without the controls and dampening I'm so used to that I'm more comfortable with. tight legal restrictions surrounding these substances
[32:21] about the mind. of our understanding of these powerful compounds, about the mind and brain.
[32:36] And, as always, thanks for watching. [theme music playing
