Psychedelics Increase Brain Plasticity, But at What Cost?

🎙 Episode premieres June 27th at 6AM PT on YouTube @cameronedwardbenton Connect With Dr. Andrew Hill : https://peakbraininstitute.com/about-pbi/ Psychedelics Increase Brain Plasticity, But at What Cost? Join neuroscientist Andrew Hill for a mind-stretching conversation exploring the surprising truth about brain plasticity and psychedelics. We delve into how substances like psilocybin and ketamine impact the brain, fostering neuroplasticity and offering a window for brain healing and rewiring. While psychedelics are showing immense potential for mental health, particularly in areas like depression psychedelics treatment brain, anxiety psychedelics neuroplasticity, and PTSD psychedelics brain repair, Hill emphasizes the crucial consideration of "at what cost?" Increased plasticity without the right environment can lead to hyper-sensitivity, triggering panic attacks, spiraling anxiety, and months of mental instability. Discover the latest in psychedelic neuroscience, including microdosing trends and neurofeedback, and understand why "set and setting" is more vital than ever for safe and effective psychedelic therapy. This isn't anti-psychedelics; it's a call for pro-awareness and a deeper understanding of psychedelic effects on brain function, brain regeneration psychedelics, and the intricate mechanisms of psychedelic brain changes for true cognitive enhancement. 🎙️ Don’t miss out!

Episode Summary

This piece is drawn from a conversation I had on the Cameron Edward Benton podcast. You can watch the original conversation. What follows is my own clinical perspective from that discussion, on what psychedelics actually do to plasticity and why "more plasticity" is rarely the thing you need.

Does more brain plasticity actually help you?

You came in chasing change. You read that psilocybin and ketamine open a window for the brain to rewire, so you started microdosing, and you assumed more plasticity meant more healing.

Most of the time, you need shaping of the plasticity you already have, not more of it.

Plasticity is the brain's capacity to change its connections. Open that capacity wide without a structure to guide it, and the brain takes the changeability and moves it the wrong direction. I see this in people who are suffering, trying many things at once, and pushing plasticity as hard as they can. The system gets more changeable, and change is not the same as improvement.

A concrete case: someone with a strongly ADHD brain takes ketamine. Ketamine is a dissociative that releases slow activity. Theta brainwaves get pushed into high gear, and now that person has severe, stuck anxiety for months. The plasticity was there. The direction was wrong.

This is why I start by looking at the brain before reaching for the chemistry. A QEEG brain map shows you where the foundational issues sit and helps you reason about which interventions might fit your particular brain rather than a generic one.

Why does neurofeedback make drugs hit harder?

I work with a lot of hard-charging biohacker types, the finance and Silicon Valley crowd. Many of them walk in microdosing every day, usually psilocybin these days. Twenty years ago the same crowd was on modafinil. The substance changes; the impulse to push the brain harder stays the same.

Here is a pattern I see in the clinic, and it is a clinical observation rather than a controlled finding. Neurofeedback raises plasticity each session in a measurable way. When people keep microdosing while doing neurofeedback, the microdose quietly turns into a macrodose. The brain got more sensitive to the compound, and a dose that used to be mild is now a full experience.

The timing is fairly consistent. Around three to five weeks into brain training, often within a couple of days, the sensitivity resets. Cannabis hits three times harder than expected. Stimulants like Adderall land about twice as hard. Psychedelics can feel three, four, five times as strong. People come in confused: did I take two Adderall, did I have way too much weed, why can't I get off the couch? The dose did not change. The brain's response to it did.

If you are doing brain training, assume your tolerance for stimulants, cannabis, and psychedelics will drop. Adjust down, or hold off, and talk to whoever is overseeing your training.

What should you optimize before reaching for psychedelics?

I am not the person reaching for every research chemical, peptide, or novel intervention. I look at the brain first, then the foundation.

The foundation is sleep, stress, and attention. Before anything aggressive, I want to know what you are doing with your sleep, how you are handling stress and your fight-or-flight response, and where your attention regulation sits. These three move more than any exotic compound, and they move it reliably.

When you genuinely need more plasticity, meditation earns a more reliable form of it, and neurofeedback raises plasticity in a controlled, measurable way each session. You can read more on the mechanics in biohacking plasticity.

Psychedelics have real use cases. I reserve them for narrow situations, and only with a physician on board. I have a good friend here in LA who does serious clinical work with ketamine. I would not have someone I am working with running a lot of that without a real expert overseeing it, because when you are actively training the brain, the variables shift fast and what you need shifts with them.

Why does set and setting matter so much?

The old psychedelic principle of set and setting is more important than it sounds, because of what plasticity does to the experience. You are opening a high-plasticity window, and whatever environment and behavior surround that window get written in more deeply.

There is a harvest problem here. It is hard to pull the psychological learning out of more ecstatic or shamanic states. Those are ordeal environments. You come back somewhat transformed, and the trouble with a lot of Western shamanism is that people go out, have an enormous experience, and bring nothing back the next day. The experience happens. The integration does not.

How does alpha-theta neurofeedback open the same door?

For people drawn to that territory, the psychonauts looking for the next step or the deeper knowledge, I often use a different category of neurofeedback called alpha-theta, or alpha synchrony training.

The mechanism: alpha-theta training brings you to the hypnagogic state, the threshold between awake and asleep, and holds you there for around twenty minutes. The training nudges the EEG toward the boundary where alpha (the brain's idle rhythm, around 8 to 12 Hz) gives way to theta (the slower 4 to 8 Hz activity you see at sleep onset). Held at that edge, you get surges of nonlinear, insight-driven awareness. If you want the background on alpha specifically, see decoding alpha waves.

The experience is genuinely interesting, and it serves the same goals people chase with psychedelics. You open a door inside yourself, step through into the place where things are sparkly and strange, and then step back, without a heroic dose forcing you to stay there. You come out of a session a little loopy for five minutes, then walk around the rest of the day grounded.

With a macrodose, you are held in the state whether you are ready or not. With alpha-theta, you choose to enter and you can leave. Most of what people want from those drugs can be reached without them.

Can you reach these states without drugs or neurofeedback?

Yes, and a lot of it is about building a container and doing ritual inside it. Ritual expression means creating a sense of the sacred and then acting within it. That is set and setting that you build yourself.

The container can be a Phish concert, Burning Man, a sun dance ceremony, a sweat lodge. Each serves a different purpose, and within any one of them people do different things: some never stop dancing, some sit on a blanket, some take substances. The shared draw is the chance to practice the ecstatic experience, to loosen the linear shape of the mind and move from pure linear thought into the receptive, insight-driven, creative space. I will be honest about the limits of my knowledge here. I can tell you why these spaces attract us. I cannot tell you precisely what the brain is doing during them.

A few practices give you real access without distorting your awareness so much that you cannot learn from the experience: dance, concentration and absorption meditation (the absorption practices, not simple mindfulness), neurofeedback, intense exercise, and playing music at a high level with other people. That last one counts because it is rich nonlinear communication you participate in rather than observe.

Why does ecstatic experience matter at all?

I would not claim it matters for every individual. As a species, it carries deep learning, art, emotion, and healing, the parts of human experience that do not live in linear, transactional thought.

There is an old idea worth knowing, and I flag it as a hypothesis rather than established fact. Julian Jaynes, in The Origin of Consciousness in the Breakdown of the Bicameral Mind, proposed that early spiritual experience came from the non-dominant hemisphere sending language across to the dominant one. Temporal lobe epilepsy produces auditory hallucinations, and the speculation is that ancient people heard "God" as their non-dominant hemisphere speaking through something like an epileptic phenomenon. It is a provocative idea about brain laterality, and it remains an idea.

The practical point is simpler. We spend most of our waking lives in a linear mode: solving problems, watching screens, being sold to, earning, consuming. Think of the posture, all of us curled into a cashew shape at a desk. Kettlebells and yoga matter because they pull the body open and rebuild the posterior chain so you are not stuck folded forward. The ecstatic, nonlinear practices do the same thing for the mind. They irrigate abilities that the linear grind leaves dry, and they give you somewhere to go to release stored stress and old material.

Mircea Eliade described the shaman as someone who travels to extraordinary reality and returns to ordinary reality. The whole point is the return, coming back with insight. If the method to get there is so altering that you are not present enough to learn, you arrive home with a cool memory and no growth. Choose the method that gets you the access while leaving you present enough to harvest it.

If you want to understand your own brain before deciding which of these paths fits, start with a brain map and the foundations. Get your sleep, stress, and attention in order, look at where your plasticity actually sits, and add the more powerful tools only with the right support around you.

I find that people can get in trouble because often we don't really need more plasticity. We need shaping of it to someone who's really suffering and trying lots of things and jacking up plasticity. The brain can take that changeability and can move it the wrong direction. So you get somebody who's like really really ADHD and they have ketamine. The theta brain waves get released into high gear and now they have severe stuck anxiety for months. So there's knowing your brain can also be navigate around that. You can look at your brain and figure out what meds or interventions might work. But I work with a lot of like let's call them bros you know the mix of finance bros Silicon Valley bros you know a lot of hard charging biohacker types and a lot of them come in micro doing constantly and you know every day they're micro doing ketamine specifically or just other no usually it's psilocybin sometimes you know 20 years ago it was medafanyl uh through through dent of Dave's uh talking about medapanyl uh deficits but you know no mostly it's um it's mushrooms these days and you know I mostly say, well, look, if you need more plasticity, I'd almost rather you meditate and get more reliable plasticity, but the neuro feedback brings up plasticity each time you do it in a measurable way. So, you might want to be a little cautious. What I find a lot of the time if people keep doing micro doing while doing neuro feedback is the micro dose turns into a macro dose. the sensitivity. The same thing happens with cannabis or with sim stimulants aderall rolin is that as you do neuro feedback the brain gets way more sensitive to it. Interesting. And maybe 3 to 5 weeks in like within a couple of days suddenly all the plasticity is reset and cannabis hits you three times harder than you expected. Stimulants are twice as impactful. Uh psychedelics three, four, five times as impactful. And people are like, "Oh my gosh, did I take two Adderall? I feel crappy." or did I have way too much weed? I can't get off the couch and like literally increased impacts from the things you're putting in your brain when you start doing brain work. So, it's a little bit, you know, I'm a little bit cautious. I'm not somebody to reach for every research chemical or peptide or random intervention. I'm more likely, okay, look at your brain. Where's the foundational stuff? Sleep, stress, and attention. What are you doing with your sleep hacking? How can we optimize these things? And I would only reach for really aggressive or unusual things like psychedelics under very narrow uh use cases and only with a doctor on board. You know, I would have a I have a good friend here in uh LA. There's a lot of work with ketamine. And so I wouldn't ever recommend somebody I was working with be doing lots of that without having someone like an expert in that on board as well because the variables can change really quickly when you're working on your brain and and what you need can change quickly. So and that makes sense too if if essentially you know the common trope is about like set set and setting for psychedelics and so understanding the environment that you're putting yourself in because you're essentially putting yourself not just for the temporary experience in a powerful state right but you're creating this high sense of plasticity and so if you're creating a high sense of plasticity you want to be setting yourself up for success to be in a positive environment to you again kind of create the maybe behavioral changes of what you want um to I also think it's it's hard to get that harvest. It's hard to pull the psychological learning, the transformation out of, you know, more ecstatic states with uh psychedelics or more shamanic states. Those are ordeal environments. And yes, we come back a little transformed. But the big problem with like western shamanism is that we go forth and trip our balls off and then don't have any growth from it the next day. we're still to our wives and girlfriend, you know, like there's this problem with transformation and um I often for people that are interested in that thing will often get into a different category of neuro feedback called alphatheta which creates this hypnogogic access brings you to the place between awake and asleep holds you there for 20 minutes or so and that creates huge surges of healing nonlinear awareness. This is of course what Dave's program is built around. 40 years is built around alphatheta alpha synchrony. It's a very very interesting experience and that particular category alphatheta alpha synchrony training I find serves the the goals of a lot of people that are these psychonauts seeking the transformation the next step the esoteric knowledge. Alpha Theta tends to give you that that access where you can open the door inside yourself and step through into that place where things are sparkly and interesting and weird and unusual and then step back through having not tripped your balls off. So like you're, you know, you come out of an Alpha Theta session, you stand up and you're a little bit loopy for 5 minutes and then you're walking around the rest of the day chill, having experiences that are relatively grounded. And so you have this wonderful access into that state, but you aren't being forced into that state the way you might with a a heroic or macro dose of a psychedelic. So while I think there are use cases for those drugs, I think that the stuff people want to get out of those drugs can be gotten without them generally. That's one of the questions I wanted to ask about was, you know, are there other ways to access these these spaces? I had another guest on who talks about like even like you music festivals and stuff which I'm a big fan of and have gone on a ton like act as these sort of like liinal spaces where you know we go on this like sort of interpersonal and extrapal like adventure that leads to a sense of transformation and goes into it. So like can you share with whatever you know like what is going on in the brain in these kinds of experiences even without psychedelics and then like what are some of the other ways that we can access this without substances or even without neuro feedback. Yeah that's a that's a great question. I'm not sure I have an answer. I think it's a sociological uh answer to some extent, but I you know really what you're doing there is creating a container and engaging in ritual expression, right? And so ritual expression is essentially creating a sacredness and then acting within it. And I think that that is the set and setting you are creating. It can be a fish concert. It can be burning man. It can be a sun dance ceremony, a sweat lodge. And you know, each will serve different purposes. But when we go into a music festival, we're going with certain perspective around what we're going to get out of it and what we like like to do there. Some folks are never stopping moving and dancing. Some folks are taking drugs. Some folks like to relax and, you know, sit in a blanket. And that is the ritual for that person. So I I'm not sure I know what's happening in the brain, but I would argue that the reason that we tend to be drawn to those environments is because of the opportunity to practice the ecstatic experience where we loosen the the linear shape of the mind. We're allowed to kind of move away from the the pure linear thoughts into the more expressive, the receptive uh the insight driven space, the creative space, the spiritual space. And I think that's why those are so attractive at the very least even if I don't know why what's actually happening during them. Yeah. Why why is that ecstatic experience so important to us as a as humanity? Well, I mean it's sort of I don't know that it is uh for every individual. I think as a species it's really important um because it there's deep learning there and there's deep you know art and and emotion and healing and all the the deep stuff. I mean some of that to get back to some of the idea of brain laterality there's some early ideas in how laterality developed that posits the question that well maybe the reason we had spiritual experiences because the non-dominant hemisphere was sending language in and hearing God was our non-dominant hemisphere. the uh Julian James the origin of the bicamal mind is a good book on that uh the idea that the two hemispheres have this linguistic capacity that temporal lobe epilepsy creates auditory hallucinations and so we were hearing God because our non-dominant hemisphere was talking to us via an epilepsy phenomena essentially. So I think that we spent a lot of time in in a linear environment. We're solving problems. We're watching TV. We're being sold to. We're fighting. We're getting money. We're consuming. It's a very linear. It's a very transactional way to be. And kind of like, you know, think about all of us who sit at desks and we're in this cashew shape all curled up all the time, right? And then we find that kettle bells in yoga become super important because of the opposite because they pull the body out and they teach the the posterior chain to become really powerful so that you're not always curled up in a fetal position as a human. And I think that the ecstatic stuff becomes important for those of us for whom we are curled up in a linear position to butcher the metaphor where we're always in that like non-spiritual non-abstract non-nuance non-emotional non you know non-aware state some education some irrigation of those tissues of those abilities can give people a lot of more rich human experience but also as a place to go to do healing to release trauma to release uh crap. Um Mercedes Elata who described shamanism shamanism talked about the shaman goes to extraordinary reality and then comes back to ordinary reality. But again the problem is harvest coming back with insight especially because a lot of the things we use historically to get to those states are very altering. you know, if you're doing your combo or your IASa or your, you know, heroic dose of LSD or something, yeah, you're going to have an experience, but are you going to be present enough to come like to learn from it, or is it going to be like, wow, I had a cool experience two days ago. Well, I I know I learned something. And if you do something that's not completely distorting but get you some of the same access which can be dance meditation with absorption practices not awareness like simple med mindfulness but like concentration absorption practices neuro feedback intense exercise um I would argue if you're a musician playing music at a high level with other people becomes one of those things as well because it's a rich nonlinear communication. that you're just participating in instead of you know deciding how it goes. Um, and I think these are really important things that we may under emphasize in this modern western linear
