Psychedelics Increase Brain Plasticity, But at What Cost?

šŸŽ™ 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. šŸŽ™ļø Don’t miss out!

The Hidden Risks of Psychedelic Brain Training: Why More Plasticity Isn't Always Better

For a deep dive into safer, measurable plasticity enhancement, see: SMR Neurofeedback: The Calm-Alert Brainwave That Trains Sleep, Focus, and Self-Control

The biohacker crowd has fallen in love with microdosing. Silicon Valley bros, finance bros, optimization enthusiasts—they're all chasing the promise of enhanced plasticity through psilocybin, ketamine, and other psychedelics. But here's what 25 years of brain training has taught me: More plasticity isn't always better. Direction matters.

The brain is remarkably adaptable, but that adaptability can work against you if you don't understand the underlying mechanisms. When someone tells me they're microdosing daily while doing intensive brain work, I get concerned. Here's why.

The Plasticity Trap: Why Your Brain Might Change in the Wrong Direction

Plasticity without direction is like giving a drunk person a sports car. Sure, they'll move faster—but probably not where they want to go.

I see this regularly in my practice. Someone with severe ADHD tries ketamine to "enhance focus." Instead of calming their overactive theta waves, ketamine amplifies them. The result? Months of stuck anxiety that's worse than their original ADHD symptoms.

The mechanism here involves thalamocortical disinhibition. Ketamine blocks NMDA receptors, which disrupts the brain's natural braking system. In someone whose theta networks are already dysregulated, this creates a runaway plasticity state that reinforces maladaptive patterns rather than correcting them.

The Sensitivity Cascade: When Microdoses Become Macrodoses

Here's something most people don't realize: brain training dramatically increases drug sensitivity. When clients combine neurofeedback with regular microdosing, I warn them about what I call the "sensitivity cascade."

Around week 3-5 of intensive neurofeedback, something shifts. The same cannabis dose that used to provide mild relaxation suddenly pins them to the couch. Their regular Adderall feels like they took twice as much. Their "micro" dose of psilocybin launches them into full-blown psychedelic territory.

The mechanism: Neurofeedback increases receptor sensitivity and network connectivity. Your brain becomes more responsive to everything—not just the training protocols. This isn't speculation; we can measure these changes in real-time through EEG coherence patterns and network connectivity metrics.

The Western Shamanism Problem: Transformation Without Integration

The fundamental issue with psychedelic optimization isn't the substances themselves—it's the context. Traditional shamanic cultures understood something we've forgotten: the ceremony matters less than what happens afterward.

In Western shamanism, people "trip their balls off" seeking transformation, then return to their regular patterns the next day. They're still impatient with their partners, still reactive under stress, still stuck in the same behavioral loops. The plasticity window opened, but without proper scaffolding, old patterns reassert themselves.

This is why I prefer alpha-theta neurofeedback for people seeking transformative states. Alpha-theta training creates that hypnagogic space between wake and sleep, generating profound non-linear awareness and healing opportunities. But unlike psychedelics, you're not forced into overwhelming states. You access the sparkly, weird, transformative space—then step back out, grounded and functional.

The neurophysiology here involves thalamocortical synchrony. Alpha-theta training strengthens communication between deeper brain structures and cortical networks, creating sustainable access to non-ordinary consciousness without the destabilization of psychedelic states.

Safer Plasticity Enhancement: What Actually Works

Before reaching for exotic substances, optimize the fundamentals that create reliable, directed plasticity:

1. Sleep Architecture Optimization Poor sleep destroys plasticity gains faster than any drug can create them. Focus on sleep spindle generation (12-14 Hz activity during stage 2 sleep) and slow-wave amplitude. These predict next-day learning capacity better than any supplement.

2. Stress-Response Training Chronic stress elevates cortisol, which actively blocks plasticity mechanisms. Train heart rate variability and practice deliberate stress exposure with recovery. This creates stress inoculation rather than stress accumulation.

3. Attention Network Strengthening The frontoparietal attention network is your brain's steering wheel. Strengthen it through focused attention meditation, neurofeedback, or challenging cognitive tasks. Without strong attention networks, increased plasticity just creates more chaos.

4. Targeted Neurofeedback Protocols SMR (12-15 Hz) training builds calm alertness and impulse control. Alpha-theta creates access to transformative states. These protocols create measurable, lasting changes without the unpredictability of psychedelics.

The Ritual Expression Alternative

Music festivals, ceremonies, intensive workshops—these create containers for transformation through ritual expression rather than chemical intervention. The mechanism involves creating sacredness, then acting within it.

At a Phish concert or Burning Man, you're engaging the same circuits psychedelics target: loosening linear thought patterns, accessing creative/spiritual states, practicing ecstatic experience. But you're doing it through movement, music, social connection, and environmental immersion.

Why this matters neurologically: These experiences activate the default mode network and salience network in ways that promote integration rather than dissociation. You get the transformative benefits without the neurochemical disruption.

When Psychedelics Make Sense (And When They Don't)

I'm not categorically against psychedelics. There are legitimate use cases: treatment-resistant depression, PTSD, end-of-life anxiety. But they should be:

  • Medically supervised by experts who understand both the substances and your individual brain patterns
  • Infrequent rather than regular (once every few months, not daily microdosing)
  • Targeted toward specific therapeutic goals, not general optimization
  • Integrated with proper preparation and follow-up work

Daily microdosing for performance enhancement? That's usually misguided. Your brain needs predictable neurochemistry to build stable new patterns. Constant low-level disruption prevents the consolidation that creates lasting change.

The Bottom Line: Know Your Brain First

Before adding any plasticity enhancer—psychedelic or otherwise—understand your starting point. What networks are overactive? What regions are underactivated? What's your stress response pattern? Your sleep architecture?

QEEG brain mapping reveals these patterns objectively. You might discover that your "focus problem" is actually anxious overthinking (excess fast-wave activity) rather than attention deficit (excess slow-wave activity). Ketamine would make the first worse and the second better.

The future of brain optimization isn't about finding the right substance—it's about understanding your individual patterns well enough to choose interventions that move you in the right direction. Sometimes that's neurofeedback. Sometimes it's meditation. Sometimes it's just better sleep.

But it's rarely daily microdosing without professional guidance and comprehensive brain assessment.

The brain's plasticity is its greatest strength and its greatest vulnerability. Treat it accordingly.

Full Transcript
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
