Welcome back to the Deep Dive. Today, we are tackling something truly profound. We’re looking

at a huge synthesis of research, over a hundred peer-reviewed studies, all pointing to one thing,

the science of awakening. That’s right. And we’re talking about everything from, you know,

neurology and molecular biology to the outcomes of major clinical trials. We’re really at this

incredible intersection. The convergence point, it feels like, where modern neuroscience is

finally shaking hands with, well, with ancient wisdom. It really is. So our mission for this

Deep Dive is to give you a solid scientific foundation for understanding how your brain

creates your sense of I. And crucially, how that sense of self can be temporarily dismantled,

what researchers call ego dissolution. And why that process is proving to be so incredibly

therapeutic for things like depression, anxiety, and addiction. So if you want the shortcut to

understanding all of this, this is it. We’re going to uncover the neurological seed of your identity

and how it can be used to help you. So let’s get started.

And the literal molecular keys that unlock profound and lasting change in the brain.

Let’s get into it.

Okay. So let’s start with the big one, the self. For so long, that felt like a philosophical idea,

you know, but science has found its address in the brain.

It has. It’s primarily located in what’s called the default mode network, the DMN.

I like to think of it as the brain’s ultimate narrative generator.

The part that’s always telling the story of me.

That’s a perfect way to describe its function.

And it’s important to realize it’s not one single spot. It’s a constellation of brain regions that

are all talking to each other. A network.

Exactly. A network that fires up when you’re not doing anything in particular, when you’re just,

you know, resting, daydreaming, thinking about the past, worrying about the future.

So it’s the neural substrate for my internal monologue.

It’s the neural substrate for the story of I. And within that constellation, there are

two real crown jewels, two structures that do the heavy lifting.

Okay. So who are they?

Who are the main architects of my identity?

First up is the posterior cingulate cortex or the PCC.

This is the main hub.

It’s where your brain does its self-reflection, where it pulls up your autobiographical memories.

So it’s constantly checking in on who I am based on my past.

Right. And what’s just astonishing about the PCC is its metabolic demand, how much energy it uses.

Yeah. The sources really highlighted this.

Tell us about that, because it’s it’s a wild number.

The PCC alone consumes up to 20 percent more metabolic energy.

So more oxygen.

More oxygen, more glucose than most other parts of the brain.

20 percent more in an organ that’s already the most energy intensive thing in our bodies.

Exactly. Think about that cost.

The brain is willing to pay this massive ongoing energy bill just to keep your story running, to maintain that ego structure.

Wow. Like a utility bill just to keep the feeling of me coherent and online 24-7.

And that coherence is cemented by the second key structure, the medial prefrontal cortex, the MPFC.

Okay.

So what’s its job in the network?

If the PCC holds the memories, the MPFC is the storyteller.

It arranges those memories in time, links them to how you felt, and then uses all that data to project into the future.

So it knits together past, present and future into one single coherent story.

That’s its job, to make sure the narrative of you makes sense over time.

This sounds like a system that needs time to develop.

I mean, babies don’t really have this coherent eye, do they?

They don’t. And the research is incredibly specific here.

The DMN isn’t fully wired up and functional until around age five.

Which is almost exactly when kids start developing a stable sense of self, when they start saying, I remember when.

Precisely. Before five, it’s all very fluid, very in the moment.

After five, the network solidifies and the self-monitoring begins.

And from that point on, it just gets stronger and stronger.

And more. Rigid. Right. That’s the downside.

That is the critical downside.

This brings us to its main function.

It’s the narrative generator, the monkey mind.

The voice in my head that just won’t shut up when I’m trying to meditate.

That’s the DMN. It’s constantly processing self-referential information.

And while we need that to function as adults, that efficiency comes at a huge psychological cost.

The cost of rigidity.

The cost of rigidity. The brain creates these, these super highways, these habitual algorithms for responding to life.

They’re efficient, but they really limit the space for new ideas.

And the source has pointed to a pretty shocking study.

It’s a very interesting statistic about this, linking it to creativity.

Yeah. It’s an anecdotal correlation, but it’s powerful.

The estimates suggest that at birth, 98 percent of us test at a creative genius level by adulthood.

That number drops to just 2 percent.

98 down to 2. That’s staggering.

It suggests that as the DMN locks in our stable identity, it simultaneously locks out a huge amount of our creative flexibility.

And when those rigid pathways become negative, like the self-critical loop in depression, the DMN itself is not going to work.

It’s not going to work.

It’s not going to work.

The DMN itself becomes the engine of the illness.

It becomes the maintenance system for the mental illness, which leads to the big question.

How can we safely and temporarily quiet a structure that is so powerful and so entrenched?

OK, so this is where it gets really interesting.

We’ve mapped the fortress of the ego.

Now let’s talk about the molecular keys that can actually open the gates.

This brings us to the serotonin 2A receptor system, or 5-HT2A.

This is the master key.

And its power is all about location, location, location.

Entirely.

These receptors are packed onto what are called layer 5 pyramidal neurons.

OK, pause there.

Why is that specific location so important?

What are layer 5 neurons?

Think of them as the output neurons of the cortex.

They’re the ones that tell the rest of the brain what the cortex has decided.

They are the final common pathway.

So they’re basically the command center.

They are the command center.

And by putting these 5-HT2A receptors right on those neurons, especially in DMN regions like the PCC and NPFC,

you can control them.

You can hijack the entire system.

You can exert a massive top-down influence on consciousness itself.

So you place the receptors where they can override the whole self-narrative network.

That makes so much sense.

And dosage is about how many of those command centers you take over.

It is.

We know that therapeutic doses of psilocybin, for example, occupy between 50% and 72% of these 5-HT2A receptors.

And there’s a direct correlation.

More receptors occupied.

The more intense the subjective experience of ego dissolution,

the stronger the feeling of unity and the loss of that self-story.

But here’s the paradox the research uncovered.

Not every molecule that binds to that receptor is actually psychedelic.

Some just do nothing profound.

Why is that?

This is one of the most fascinating recent discoveries.

It’s a concept called functional selectivity or biased agonism.

Biased agonism.

Yeah.

So think of the receptor not as a simple lock but like a complex safe with multiple internal switches.

A non-psychedelic molecule like leuceride fits the lock but it only flips one switch.

It activates what’s called the G-protein pathway.

Which is responsible for what short-term stuff.

Exactly.

Short-term signaling.

But a true psychedelic is a biased agonist.

It flips the G-protein switch and a second crucial switch.

It also activates the beta-arrestin pathway.

Okay.

So it’s the beta-arrestin pathway that’s the key to the whole experience.

It’s the key to the full functional outcome.

Dual activation is what kicks off the entire cascade that leads to the ego-dissolving state.

The difference between a dud molecule and a life-changing one is literally one tiny chemical pattern that flips that second switch.

The precision of that is just mind-blowing.

But this leads us to an even bigger discovery.

Something that shifts the whole conversation from the trip to the healing.

It does.

Let’s talk about neuroplasticity.

Specifically BDNF and the TRKB receptor.

BDNF.

The brain-derived neurotrophic factor, basically miracle growth for the brain.

That’s the one.

And this is the core aha moment from recent research, some of it just published in 2023.

Scientists discovered that psychedelics like LSD and psilocin bind directly to the TRKB receptor.

Which is the main receptor for BDNF.

Correct.

And here’s the part that should make everyone just stop and listen.

They bind to that receptor with up to 1,000 times higher affinity than traditional antidepressants.

1,000 times.

Yeah.

That’s not a small difference.

It works so slowly and indirectly to boost BDNF.

This is like a direct mainline.

It shows a fundamental dual mechanism of action.

You have the serotonergic path, the 5-HT2A activation that causes the acute ego dissolution, the TRIP.

Right.

And then you have this neurotrophic path, the TRKB activation, that is responsible for the lasting antidepressant effects.

The profound neuroplasticity.

So you’re getting a massive shift in consciousness and triggering an unparalleled growth response

in the physical brain all at the same time.

At the exact same time.

It’s a biological reorganization.

So what does that timeline look like?

After a dose, how quickly does this miracle start working?

This is so key for the whole idea of an integration window.

The timeline is incredibly fast.

Within just one hour, you see an upregulation of what are called immediate early genes.

These are the first responders that kick off the growth programs.

One hour.

Then within four to six hours, you can actually measure plasma BDNF levels rising faster.

And at the 24-hour mark, the physical growth begins.

The brain starts sprouting new dendritic spines.

So actual physical changes to your neurons within a single day.

That’s unheard of in psychopharmacology.

And it’s sustained.

For weeks and months, we see this continued synaptogenesis.

This is why integration work in that initial window, especially that first day, is so critical.

You’re maximizing the brain’s potential to physically rewire itself.

The insight sticks.

Because the structure literally changes to support it.

Yeah.

OK.

So how does glutamate, the brain’s main gas pedal, fit into all this?

Glutamate is the bridge.

The 5-HT2A activation on those layer 5 neurons causes a massive rapid release of glutamate.

And that surge of glutamate is what, in turn, activates the BDNFT-RKB pathway.

It’s a beautiful cascade.

Serotonin to glutamate to BDNF.

The psychedelic is just the first domino.

It’s the switch.

It initiates a healing cascade.

It initiates a healing cascade that continues long after the drug has left your system.

This all provides a perfect explanation for the predictive coding framework, which is the modern way of understanding how our brains build our reality.

It does.

This is the cognitive piece of the puzzle.

Your brain isn’t just a passive recorder of information.

It’s a prediction machine.

And normally, the DMN holds those predictions with very high confidence or precision.

Exactly.

Precision is the brain’s confidence level in its own beliefs.

And in a state like depression, the DMN has a very high precision.

Very rigid belief like, I am worthless.

And it filters all incoming data through that belief, so everything just confirms it.

Right.

It’s a self-perpetuating loop.

What the psychedelic state does is temporarily reduce the precision of those top-down predictions.

The ego’s rigid beliefs suddenly become wobbly, uncertain.

It’s like turning down the volume on that inner critic.

A perfect analogy.

And with that volume turned down, new information, new sensory data, new insights are generated.

And that’s what we’re talking about.

New data, new insights can finally flood in unchecked.

It allows for Bayesian belief updating, as the researchers call it.

It opens the cognitive door.

It creates the flexibility to consider and actually adopt new positive models of yourself and the world.

The neuroplasticity is the hardware upgrade.

The predictive coding chain is the software update.

So we’ve got the map of the self and the key to unlock it.

Now let’s compare the different ways to get there.

The sources lay out three very distinct pathways to this state of ego dissolution.

Yes.

And comparing them is so revealing.

Let’s start with the one we’ve been discussing, the psychedelic pathway.

This is acute chemical disintegration, the sledgehammer approach.

It really is.

On a network level, you see this immediate dramatic drop in DMN connectivity.

The coupling between the PCC and the MPFC just goes offline.

And blood flow to the PCC, that energy hog, can drop by up to 20%.

20%.

So the self narrator is literally being starved of resources.

It’s being put on furlough, yeah.

And at the same time, global connectivity explodes.

The brain becomes entropic.

Meaning regions that normally don’t talk to each other suddenly start having conversations.

Vigorous conversations.

The visual cortex starts talking to the DMN.

This is the neural basis for things like synesthesia and that feeling of oceanic boundlessness.

Where the boundary between you and the world just dissolves.

Exactly.

The effects are acute, you know, four to eight hours.

But the structural changes from that BDNF surge can lead to lasting damage.

Can lead to lasting personality changes.

Like increased openness for months or even years.

Okay, now let’s pivot.

Path number two.

The meditation pathway.

This is the complete opposite, right?

It’s voluntary, gradual, top-down control.

It’s the polar opposite in mechanism.

This is sustained neural retraining.

When you look at the brains of experienced meditators, you see a consistent long-term decrease in DMN activity during their practice.

But the DMN doesn’t just get shut down.

It gets a supervisor.

That’s it.

Instead of dissolving into chaos, with meditation, you see an increased coupling between the DMN and executive control networks.

Especially a region called the anterior cingulate cortex, the ACC.

And the ACC’s job is what?

It’s like the brain’s air detector and attention regulator.

So meditation is basically training your ACC to watch the DMN, to watch the monkey mind, without getting swept away by it.

So you’re not silencing the storyteller.

You’re just learning not to believe every word it says.

You’re developing a witness.

You’re developing meta-awareness.

A witness consciousness.

It’s not 5-HT2A mediated at all.

It’s just pure voluntary attentional control.

And what’s amazing is you can see these DMN changes on a brain scan after just two to three weeks of daily practice.

So two very different paths.

One chemical explosion, one slow, disciplined training.

But the third path, the shamanic journey, this is where the real paradox comes in.

This is, for me, the most fascinating part of the real paradox.

The most fascinating part of the research.

Shamanic trance, often induced by something like rhythmic drumming, produces the same ego dissolution, the same mystical states as psychedelics.

But the brain is doing the opposite thing.

The complete opposite.

Instead of DMN activity going down in a shamanic trance, DMN activity actually increases.

How is that even possible?

How could a quiet DMN and a loud DMN lead to the same feeling of losing yourself?

The key seems to be a concept called brain criticality.

Criticality.

Think of it as the brain operating right at the edge of chaos.

The sweet spot between perfect order and total randomness.

The rhythmic drumming entrains the brain waves, pushing the whole system toward this highly critical, highly complex state.

So it’s not turning the volume down, it’s turning the complexity and adaptability way, way up.

So far up that the old rigid structures like the ego can’t hold together anymore and they dissolve into this more interconnected state.

It’s a different way to break the pattern.

Wow.

So you can get there by shutting the system down or by training it or by pushing it to its absolute maximum computational limit.

It shows there are multiple valid routes to the same destination, which is just incredible.

Okay, let’s ground this in the body.

Because transformation isn’t just in your head.

It needs a physical safety net.

This brings us to a really crucial framework.

Polyvagal theory.

Yes.

Steven Porge’s work.

It’s essential for understanding why ego dissolution can be either profoundly healing or deeply harmful.

It all depends on the state of your nervous system.

So he proposes this three circuit hierarchy of safety.

Right.

And we move down the ladder as threat increases.

At the very top, the newest, most evolved system is the ventral vagal system.

The VVS.

This is our social engagement system.

It is.

It’s what allows us to feel safe, connected, calm.

It controls the muscles in our face, our voice.

When your VVS is online, you feel present and resourceful.

This is the state where healing is possible.

But if the threat is too big, we drop down the ladder to the next system.

We drop down to the sympathetic system.

Fight or flight.

Pure mobilization.

Heart racing.

Muscles tensed.

We’re ready to run or fight.

And if that doesn’t work.

If the threat is inescapable.

We bottom out into the oldest, most primitive system.

The dorsal vagal system.

The DVS.

This is the reptilian freeze response.

Immobilization.

Shut down.

Numbness.

Dissociation.

And the central idea is that.

True deep therapeutic work can only happen when we’re in that top state.

In the ventral vagal system.

It’s the only place it can happen.

And what’s emerging now is research showing that psychedelics actually modulate our vagal tone.

Yeah.

They seem to interact with those same five HD2A receptors to increase what’s called heart rate variability or HRV.

Which is a direct measure of our nervous system’s flexibility and resilience.

It’s a marker of good vagal tone.

So the medicine itself might be helping to nudge the system.

Toward that safe ventral vagal state.

This brings us to the most critical distinction for anyone listening.

The difference between therapeutic ego dissolution and pathological dissociation.

This is everything.

Therapeutic ego dissolution happens when you are in a ventral vagal state.

Your nervous system feels safe so it gives you permission to let go.

The experience is one of unity, connection, and healing.

But if you have that same loss of self while your nervous system is screaming danger.

Then it becomes pathological dissociation.

That happens in the dorsal vagal state.

The feeling isn’t unity.

It’s fragmentation, terror, depersonalization.

It’s not I am safe to let go.

It’s I am being forced to disappear.

And that can be incredibly re-traumatizing.

Deeply.

This is why the state of the body is paramount.

And we know that 90% of the vagus nerve’s fibers are afferent.

They send signals from the body up to the brain.

Your body tells your brain whether it’s safe enough to change.

So let’s talk about the proof.

The hard data.

The clinical trials that show just how powerful this process can be when it’s done right.

Let’s start with that huge Johns Hopkins study on major depression from 2020.

The results from that study were just a landmark.

They really shifted the entire conversation around mental health treatment.

So what did they find?

How much did people’s depression actually change?

The change was massive and immediate.

Using the standard depression scale.

The mean score for the group dropped from 23, which is moderate, to severe depression, down to 8, which is basically remission.

And how quickly did that happen?

One week after the treatment.

And it was sustained.

When you compare that to traditional antidepressants, the magnitude is just, it’s on another planet.

It really is.

The statistical measure they use is called Cohen’s d, an effect size.

A large effect is 0.8.

The effect size here was between 2.5 and 2.6.

So what does that actually mean?

2.5.

It means the effect was so large there was almost no overlap between the treated group and their own baseline scores.

The lead researcher was quoted saying the effect was about four times larger than what clinical trials have shown for traditional antidepressants.

Four times larger.

And the remission rate?

58% of patients were in full remission at four weeks.

It’s just unheard of.

And we see similar things with anxiety, right?

Especially that study on cancer patients.

Yes.

That was a crucial one.

They worked with patients facing a lot of anxiety.

They worked with patients facing a life-threatening diagnosis, dealing with profound existential dread, and they saw these sustained decreases in death anxiety.

83% had a response for anxiety six months later.

And that study gave us the smoking gun.

It wasn’t just taking the drug that healed them?

No.

They found that the intensity of the mystical experience, the degree of ego dissolution, that feeling of oceanic boundlessness on the day of the session, was what predicted the long-term positive outcome.

So the more complete the ego dissolution…

The better the long-term healing.

The experience of profound connection is the antidote to the isolation of depression and anxiety.

This power obviously demands extreme caution.

Which brings us back to that distinction between ego dissolution and dissociation, especially for people with trauma.

It’s the most important safety principle.

Ego dissolution is healing when it’s voluntary and held in a state of vagal safety.

Dissociation is a defense mechanism that happens in a state of dorsal vagal threat.

So the guide and the environment are basically determining whether that door opens to heaven or hell.

That’s a good way to put it.

This is why the sources stress the stabilization principle for anyone with complex trauma.

They must do the preparatory work first.

They need to have the skills to self-regulate before they attempt to dismantle the ego’s defenses.

Otherwise you’re just flooding a system that doesn’t have the capacity to handle it.

And you risk making things much, much worse.

It’s an ethical imperative to assess for readiness.

Okay, so this brings all the science back to practical application.

We know the brain can be rewired.

But the outcome is shaped by non-drug factors.

Set, setting, and integration.

The classic triad.

Set is your internal world.

Your intention, your history, your mindset.

Setting is the external world.

The physical space.

The guide.

The music.

Let’s talk about the music because it’s not just background noise in these studies.

Not at all.

It’s a critical part of the therapeutic container.

It’s highly curated, usually instrumental.

No lyrics.

Why no lyrics?

To avoid imposing a narrative.

You don’t want the music telling you what to think or feel.

It’s there to be an emotional support.

An auditory safety net that helps you surrender to your own process.

And the guide’s role is also very different from traditional therapy.

It’s much more passive.

It’s a non-directive presence.

The mantra is, less is more.

You let the medicine and the person’s own intelligence do the work.

The guide is there to hold steady.

It’s a space to co-regulate their nervous system to be that anchor of ventral vagal safety.

And the real work, the translation of insight into change, that all happens after.

That’s the integration imperative.

It is.

And the sources lay out this beautiful four-level framework for integration, which maps perfectly onto the neuroscience we’ve been discussing.

Let’s walk through it.

It starts with the physical level.

The serpent.

The serpent is the hardware.

It’s your body.

Integrating at this level means recognizing the DMN is real tissue.

BDNF is a real growth factor.

So you do practices, breathwork, good nutrition, movement, to support that physical rewiring.

Then we move up to the emotional level.

The jaguar.

The shadow.

The DMN is where we store our wounds, those rigid emotional patterns.

Ego dissolution brings them to the surface.

Jaguar integration is doing the work to heal those exposed wounds, to process the trauma that’s been uncovered.

Then the story level.

The hummingbird.

The hummingbird is the storyteller.

Our personal mythology run by the MPFC.

Ego dissolution makes that story fluid.

So integration here is the act of consciously rewriting your own myth, adopting a more empowering and resilient narrative about your life.

And finally, the highest level.

The eagle.

Unity.

Ego dissolution is flying with eagle.

It’s that transcendent experience of non-dual awareness, of interconnection.

Eagle integration is about carrying that feeling of unity back into your daily life, letting it inform your actions and relationships.

This whole map really answers the central mystery, doesn’t it?

How does losing yourself actually heal the problems of the self?

It does.

There are four clear mechanisms.

One, it reduces rumination, just giving you a break from the negative loops.

Two, it allows for belief updating, breaking the hold of rigid, negative thoughts.

Three, it provides an experience of connectedness, which is the direct antidote to isolation.

And the fourth is the physical rewiring itself.

Exactly.

Zero plastic rewiring.

The BDNF surge gives you the biological opportunity to build new, healthier circuits.

But, and this is the key, the experience alone is not enough.

Right.

Experience plus integration equals lasting change.

You have to do the work to translate the insight into behavior, especially in that critical one to seven day window when the brain is most plastic.

Otherwise, the DMN just rebuilds itself back to the way it was.

What an incredible journey from the energy consumption of a tiny brain region all the way to rewriting your personal myth.

We started with where is the self?

Yeah.

And we found it in the default mode network, that storyteller that’s constantly running.

And we found the molecular keys, 5-HT2A for the experience and that Cherokee BBB DNF system for the lasting change, which is just a thousand times more powerful than anything we’ve had before.

And we saw the different routes to get there, the chemical force of psychedelics, the discipline of meditation, the rhythmic power of shamanic journeying, all roads leading to a similar place.

But all of it resting on a foundation of safety, of being in that ventral vagal state where the body can finally say, OK, it’s safe to change now.

It’s a stunning convergence of languages, isn’t it?

What ancient traditions called transcending the illusion of the separate self, neuroscience is now calling the downregulation of the DMN.

And what they called healing or awakening, we can now see under a microscope as BDNF driven synaptogenesis.

It’s the same truth, just in a different language.

Exactly.

It’s an amazing validation of these ancient practices.

But as always, we want to leave you, the listener, with one final provocative thought to chew on.

And for me, the deepest question that remains is the one we touched on, that central paradox.

Why do shamanic practices, which increase DMN activity, produce the same ego dissolution as psychedelics and meditation, which decrease it?

It suggests the key isn’t just turning the volume up or down.

It might be more about the quality of the network’s activity.

It’s complexity.

It’s criticality.

It’s connectivity.

Which implies that the future of all this might be in highly personalized protocols.

Finding the unique neural route that works best for your brain to achieve that state of transition.

A fascinating challenge for you to think about as you integrate all of this.

Thank you for joining us on this deep dive.

We’ll see you next time.
