Your Body Is the Scoreboard

From Heart to Brain: The Neuroscience Behind Connection and Calm

Welcome back to Taste of Truth Tuesdays, where we maintain our curiosity, embrace skepticism, and never stop asking what’s really going on beneath the surface. Last week, I prepared you for this episode, so if you missed out, please check it out! It’s short and sweet.

Now, for today’s episode….

Let me ask you something:

Why does your body feel like it’s on high alert… even when nothing “bad” is happening?
Why do you either trust too quickly or not at all and end up anxious, burned out, and ashamed?
Why is it so damn hard to regulate your emotions, especially when you’re great at controlling everything else?

If those questions hit a little too close to home… this episode is for you.

Last season, we dove deep into complex trauma through Pete Walker’s From Surviving to Thriving, unpacking how childhood neglect, emotional abuse, and developmental trauma shape adult patterns.

And today? We’re going even deeper — through the lens of neuroscience.

Because what if these aren’t personality quirks or moral failings? What if your brain and body are actually doing their best to protect you, using adaptations wired by Complex PTSD?

My guest today is Cody Isabel | Neuroscience, a neuroscience researcher and writer whose work has become a game-changer in trauma conversations. He holds a degree in Cognitive Behavioral Neuroscience, has training in Internal Family Systems psychotherapy, and specializes in the emerging field of Psychoneuroimmunology — the study of how your thoughts, brain, and immune system interact.

His Substack article, “PTSD & Complex PTSD Are NOT the Same Thing,” has been one of the clearest, most validating reads on this topic I’ve found.

So, if you’ve ever felt stuck, shut down, reactive, misunderstood, or like your nervous system has a mind of its own…. stay with me.

Because today we’re not just talking trauma.
We’re talking nervous system intelligence.
We’re talking identity repair.
We’re talking real, embodied healing.

And before we get into that, I want to bring a few threads together from past episodes—because they’re all woven into this conversation.

We’ve talked about fawning, the lesser-known trauma response that shows up as chronic people-pleasing, self-abandonment, and conflict avoidance—especially common in those who’ve survived high-control environments. In this episode with Theresa, we also explore the stress cycle. According to Selye’s General Adaptation Syndrome, your body moves through three stages when facing ongoing stress: Alarm, Resistance, and eventually, Exhaustion. And fawning, while behavioral, can easily become your nervous system’s go-to tactic—especially during prolonged stress or in the presence of power dynamics that feel threatening.

We have talked about the Emotional Hijack and how trauma impacts the brain in this episode.

We’ve also referenced the vagus nerve, but not specifically Polyvagal Theory—but today, we’re going deeper. Instead of seeing your stress responses as “malfunctions,” it reframes them as adaptive survival strategies. Your nervous system isn’t betraying you—it’s trying to protect you. It’s just working off old wiring.

Think of it like this:

Your nervous system is constantly scanning for cues of safety or threat—this is called neuroception. And based on what it detects, your body shifts into different states—each with a biological purpose.

The Polyvagal Chart breaks this down into three major states:

1. 🟢 Ventral Vagal – Social Engagement (Safety)

This is your “rest-and-connect” zone. You feel grounded, calm, curious, and open. You can be present with yourself and with others. Your body prioritizes digestion, immune function, and bonding hormones like oxytocin. You’re regulated.

This is the state we’re meant to live in most of the time—but trauma, chronic stress, or inconsistent caregiving can knock us out of it.

2. 🟡 Sympathetic – Fight or Flight (Danger)

When your system detects danger, it flips into high alert. Blood rushes to your limbs, your heart races, your digestion shuts down. You either fight (rage, irritation) or flee (anxiety, panic). This is survival mode. It’s not rational—it’s reactive.

And if that still doesn’t resolve the threat?

3. 🔴 Dorsal Vagal – Freeze (Life Threat)

This is the deepest shutdown. Your system says: “This is too much. I can’t.” You go numb. You collapse. You may dissociate, feel hopeless, or emotionally flatline. It’s not weakness—it’s your nervous system pulling the emergency brake to conserve energy and protect you.

Here’s what’s crucial to understand: these responses aren’t choices. They’re biological defaults. And many of us are stuck in loops of fight, flight, or freeze because our systems never got a chance to complete the stress cycle and return to safety.

So instead of shaming yourself for overreacting or shutting down, what if you asked:

“What is my nervous system trying to do for me right now?”
“What does it need to feel safe again?”

That shift—from judgment to curiosity—is the beginning of healing.

And we’ll connect this to another major thread—attachment systems, which we haven’t unpacked in depth yet, but absolutely need to.

Your attachment system is the biological and psychological mechanism that drives you to seek safety, closeness, and emotional connection—especially when you’re under stress. It develops in early childhood through repeated interactions with your caregivers, shaping how you regulate your emotions, perceive threats, and relate to others. If those caregivers were emotionally attuned, predictable, and responsive, you likely formed a secure attachment. But if they were inconsistent, neglectful, controlling, or chaotic… your attachment system learned to adapt in ways that may have kept you safe then—but cost you connection now.

In The Happiness Hypothesis, Jonathan Haidt points to a disturbing moment in psychological history that disrupted the natural development of secure attachment: the rise of behaviorism in the early 20th century.

John B. Watson, a founding figure of behaviorism, famously applied the same rigid, mechanistic principles he used on rats to raising human children. In his 1928 bestseller The Psychological Care of Infant and Child, he urged parents not to kiss their children, not to comfort them when they cried, and to withhold affection—believing emotional bonding would produce weak, dependent adults.

By the mid-20th century, attachment theory began to challenge these behaviorist claims. John Bowlby, in the 1950s, argued that infants form emotional bonds with caregivers as an innate survival mechanism—not merely as conditioned responses to rewards, as behaviorism suggested. His work, drawing from ethology, psychoanalysis, and control systems theory, moved beyond behaviorism’s narrow stimulus-response framework. Mary Ainsworth’s empirical research in the 1960s and ’70s, through her Strange Situation study, confirmed that attachment styles stem from caregiver sensitivity and infant security needs, rather than simple conditioning.

Yet, ironically, during the 1970s and ’80s, Christian parenting teachings—particularly those popularized by figures like Dobson—adopted and amplified the very behaviorist ideas that attachment research was already disproving. These teachings emphasized strict discipline and emotional control, often citing Scripture to justify practices rooted in outdated psychological theories rather than theology.

Let that sink in.

For decades, dominant parenting advice discouraged emotional responsiveness, treating affection not as a necessity but as a liability.

This wasn’t just bad advice—it was the psychological equivalent of nutritional starvation. Instead of missing vitamins, children missed attunement, safety, and connection. As attachment research has since shown, those early emotional experiences shape nervous system development, stress regulation, and whether someone grows up trusting or fearing closeness.

So, when we talk about stress responses like fawning… or chronic over-functioning… or emotional dysregulation… we’re often seeing the adult expression of a nervous system that never learned what safety feels like in the presence of other people.

And that’s why today’s conversation matters. Because healing isn’t just about rewiring thought patterns. It’s about rebuilding your felt sense of safety—in your body, in your relationships, and in your life.

And if you are anything like me and have found yourself wondering… why your nervous system reacts the way it does… or why regulating your emotions feels impossible even when you “know better” … this episode will connect the dots in ways that are both validating and eye-opening.

We’re talking trauma, identity, neuroplasticity, stress, survival, and what it really means to come home to yourself.

The topics we explore:

  • The critical differences between PTSD and Complex PTSD — and how each impacts the brain and body
  • Why CPTSD isn’t just a fear response, but a full-body survival adaptation that reshapes your identity
  • What it means to heal “from the bottom up,” and why insight alone isn’t enough
  • How books and language can validate our experience — without replacing the need for somatic work
  • The push-pull of relational safety: why CPTSD makes connection feel risky, even when we crave it
  • How trauma affects the Default Mode Network, and why healing often feels like rediscovering who you are

Whether you’re navigating relational triggers, spiritual disorientation, or the long road of recovery, this conversation offers clarity, compassion, and a grounded path forward.

Transcending Trauma Healing Complex PTSD with Internal Family Systems Therapy

The Deluded Brain: Why Control Feels Safe, Certainty Feels Holy, & Complexity Feels Threatening

Welcome to Taste Test Thursday! You know how online debates often turn into full-blown keyboard wars? People lash out with rage when their beliefs whether political, religious, or social are challenged. But why? What’s behind these intense, emotional responses?

What if it’s not just about bad ideas, but something deeper a brain imbalance? What if our need for certainty and addiction to outrage comes from the way our brains are wired to process the world?

Today we’re diving into the neuroscience behind these defensive reactions. We’ll see how the brain’s wiring for survival influences everything from ideological rigidity to emotional hijacking. We’re setting the stage for something important that we’ll explore this upcoming Tuesday how Complex PTSD and PTSD are NOT the same thing. This is an episode you won’t want to miss, especially if you’ve ever felt stuck in a cycle of intense emotional reactions that you just can’t control.

Let’s review something we’ve discussed before: Amygdala Hijacking. If you remember, the amygdala is a part of our brain that processes emotions like fear and anger. Now, when the amygdala gets triggered especially in stressful or traumatic situations it can completely bypass the more rational prefrontal cortex. This results in what we call an “emotional hijack,” where the brain goes straight into fight-or-flight mode often in situations that don’t actually require that level of reaction.

This kind of response helps explain why some people find comfort in fundamentalism.

“At its most basic, the allure of fundamentalism, whether religious or ideological, liberal or conservative, is that it provides an appealing order to things that are actually disorderly.”
Peter Mountford The Dismal Science

That line hits at something crucial we have explored many times before: the human brain craves order, especially in the face of chaos. The illusion of control is one of our brain’s favorite coping mechanisms and when we find a system (religious, political, or otherwise) that delivers black-and-white certainty? You get a dopamine hit.

Rigid ideologies offer a tidy framework that feels safe and predictable especially in times of confusion, disillusionment, or personal crisis. That’s not just philosophy. That’s neurology.


When Chaos Was the Norm, Control Becomes a Coping Mechanism

For many of us, rigid beliefs aren’t just intellectual frameworks. They’re emotional survival strategies.

The need for control, the drive for perfection, the desire to be “good enough” to earn love these weren’t just quirks of personality. They were adaptations to childhoods where emotional needs weren’t met. And like many people who grew up in households marked by emotional neglect, those patterns shaped everything: our relationships, our careers, our bodies, and the ideologies we clung to.

Psychologists like Alice Miller and Elan Golomb have long noted how children raised in emotionally unavailable or narcissistic homes often create a false self a version of themselves designed to gain approval and avoid rejection.
It’s a blueprint that gets carried into adulthood, often unconsciously.

That’s why fundamentalist spaces feel so magnetic to people with childhood trauma. They offer:

  • Clear rules instead of emotional chaos
  • “Unconditional” love that’s actually highly conditional
  • A surrogate parent in the form of a deity or ideology that tells you who to be

Religious trauma often echoes family trauma—because it’s a new version of the same wound.


When Identity Is Built on Compliance

When a belief system rewards obedience over curiosity, it recreates the dynamics of an authoritarian household. You’re loved when you perform correctly. You belong when you don’t question. You’re “good” when you conform.

So what happens when you start to deconstruct?

The moment someone questions the “truth,” it’s perceived as a betrayal—not just of doctrine, but of identity and tribe. And that’s when we see:

  • Verbal attacks – Heretic. Traitor. Bigot.
  • Social ostracism – Canceled. Shunned. Ghosted.
  • Online harassment – Dogpiling and moral outrage.
  • Even physical aggression – History is full of examples, from witch hunts to ideological purges.

But this isn’t just about “bad actors.” It’s about brains shaped by fear.

When your childhood taught you that being wrong = being unloved, then someone challenging your beliefs doesn’t just feel uncomfortable it feels unsafe.
Disagreement triggers:

  • Cognitive dissonance – That gut-wrenching anxiety when facts don’t fit your worldview
  • Fear of consequences – Hellfire or public shaming
  • Loss of self – Because the belief was the identity
  • Loss of community – The people who “loved” you might now condemn you

The Brain’s Role in Certainty Addiction

Neuroscience adds another layer here—one that makes ideological rigidity more understandable, even if it’s not excusable.

Dr. Iain McGilchrist, in The Master and His Emissary, outlines how the brain’s left and right hemispheres don’t just process information differently—they perceive reality differently.

❌ Not: “Left brain = logic, Right brain = creativity.”
✅ But: “Left brain = control, categorization, and certainty. Right brain = context, relationship, and meaning.”

In a balanced brain, the right hemisphere leads—it sees the big picture, embraces nuance, and stays grounded in lived reality. The left hemisphere refines, classifies, and helps us act.

But modern culture has flipped the script. We’ve let the left hemisphere hijack our perception, reducing the complex to the manageable, the mysterious to the measurable. In this flipped hierarchy:

  • Ambiguity feels threatening
  • Context gets stripped away
  • Relationship is sacrificed for abstraction
  • And certainty becomes a kind of drug

That’s why ideological possession feels so safe. The left brain loves a clear system, even if it’s oppressive. It would rather be certain and wrong than uncertain and real.

So, when someone questions your belief, it’s not just inconvenient. It shatters the left brain’s illusion of control. And when that illusion is all, you’ve known since childhood, the reaction isn’t just intellectual-it’s existential. a threat.


When Belief Becomes Identity

Jonathan Haidt, in The Righteous Mind, explains that we don’t arrive at beliefs through pure logic. We have moral intuitions quick, gut-level judgments and then our reasoning brain (usually the left hemisphere) steps in, not to find the truth, but to defend the tribe.

The moment someone questions our “truth,” we don’t hear it as a conversation—we hear it as an attack.

What happens next?

Verbal Attacks:
When someone questions a core belief, the response often isn’t curiosity—it’s insults, belittling, or outright contempt. In faith spaces, that might look like calling someone a heretic. In political spaces, it’s labels like traitor, bigot, or grifter.

Social Ostracism:
Both religious and political groups punish deviation. Doubters are canceled, excommunicated, or ghosted. Deconstruct your faith? You might lose your church community. Question political orthodoxy? You might lose friends—or your job.

Online Harassment:
The algorithm rewards outrage. Post a thoughtful question about a sacred ideology and you’ll get dogpiled. Our moral tastebuds, as Haidt would say, are being hijacked by dopamine-fueled tribalism.

Physical Aggression:
At the extremes, ideological certainty becomes dangerous. From holy wars to revolutions, the ugliest parts of history stem from one belief: we’re right, and they’re evil.


Why We React This Way: The Psychology of Threat

When beliefs are fused with identity, disagreement feels like annihilation. Especially when the community around us reinforces that fusion. Here’s the pattern:

  • Fear of Deviation: Questioning is framed as betrayal either spiritual or social.
  • Cognitive Dissonance: New ideas create discomfort, and doubling down feels safer than rethinking.
  • Fear of Consequences: From hellfire to being canceled, the cost of questioning is high.
  • Identity Threat: When belief equals self-worth, letting go feels like losing yourself.
  • Social Pressure: Communities often reward conformity and punish dissent.

This is where McGilchrist and Haidt align beautifully: one shows how the brain gets hijacked by the need for control, the other shows how morality binds us to our tribe and blinds us to complexity.


Make-Believe, Morality, and the Group

In our episode with Neil Van Leeuwen, author of Religion as Make-Believe, we unpacked another crucial insight: factual beliefs are flexible, but identity-based beliefs aren’t. They don’t require evidence. In fact, falsehoods often serve the group better because they signal loyalty, not logic.

This is why both sides of a political aisle can believe obviously contradictory things because the truth is secondary to belonging. And once we belong, we don’t think critically–we defend instinctively.


The Antidote: Intellectual Humility

The only way out is through a kind of self-aware disruption.

  • Open Dialogue: Spaces where disagreement isn’t punished—but explored.
  • Supportive Community: Groups that allow for doubt, evolution, and honest questioning.
  • Personal Reflection: A willingness to examine the stories we tell ourselves—and why we need them.
  • Interdisciplinary Curiosity: Instead of staying in one thought silo, we pull from neuroscience, sociology, philosophy, and lived experience.

Fundamentalism, at its core, is the elevation of certainty over curiosity. But healing, freedom, and truth? They live on the other side of that certainty.


So, what’s one belief you once clung to tightly only to realize it wasn’t the whole truth?

Let’s talk about it in the comments.

And remember:

Maintain your curiosity, embrace skepticism, and keep tuning in. 🎙️🔒
We’re not here to worship reason or reject it.
We’re here to see more clearly.

Untangling the Threads of Chronic Pain, Trauma, and Healing

How Emotional Trauma Contributes to Chronic Pain

If you had asked me a year ago why my body hurt so much—why my hips ached, my calves tightened with every step, or why even walking on the treadmill felt like a chore—I would have said it was from overtraining or poor posture. What I couldn’t articulate then was that my pain wasn’t just physical. It was a complex dance involving my nervous system, my fascia, and my body’s attempt to protect itself after years of unresolved trauma.

Our nervous system plays a fundamental role in chronic pain. When we experience physical or emotional trauma, our body reacts by creating a heightened state of alertness. Over time, these experiences are encoded in the nervous system as neurotags—clusters of physical, emotional, and cognitive memories that influence how we react to stress and pain. Chronic pain, I’ve learned, is often an echo of this activation. It’s not just about tight muscles or structural imbalances—it’s a survival mechanism trying to make sense of and respond to past trauma.

This is the story of how I’ve started to untangle it all, and how chronic pain, emotional wounds, and trauma are all intricately tied together in ways I never imagined.

The Connection Between Chronic Pain and Trauma

For years, I treated my body like a machine. During my bodybuilding days, I pushed through discomfort, ignored signs of overtraining, and celebrated soreness as a badge of honor. But what I didn’t understand then was how my nervous system was quietly keeping score.

Chronic pain, I’ve learned, isn’t just about tight muscles or structural imbalances—it’s a survival strategy. When we experience trauma, whether from overtraining, stress, or emotional wounds, our nervous system can get stuck in a heightened state of alertness. It’s like a smoke alarm that keeps going off, long after the fire has been extinguished.

Fascia, the connective tissue that surrounds every muscle and organ in our body, plays a fascinating role in this process. Fascia isn’t just structural—it’s sensory. It’s packed with nerve endings that communicate directly with the brain. When the body perceives danger (even subconsciously), the fascia can tighten, creating patterns of tension that mirror emotional or physical trauma. In my case, that tension showed up in my psoas muscles, my calves, and my lower back—all areas associated with safety and movement.

The more I explored these connections, the more I began to see that pain wasn’t random—it was a message from my body. And it was asking me to listen.


The Power of Neurotags: How Pain and Trauma Intersect

One of the most eye-opening concepts I’ve come across in my journey is the idea of neurotags—a term used to describe the brain’s way of organizing and processing sensory, emotional, and cognitive information. Neurotags are like maps of experiences that are built over time, creating an interconnected network of physical sensations, emotions, and thoughts that work together to form a response to stimuli.

Here’s the kicker: Chronic pain is often stored in these neurotags. When trauma occurs—whether physical, emotional, or psychological—it gets encoded in the nervous system as a pattern. These patterns are not just about the physical experience of pain, but also the emotions and thoughts tied to that experience.

When trauma is stored in the nervous system, it doesn’t just affect how we feel physically; it affects our entire emotional and cognitive landscape. For example, someone who has experienced physical trauma may also experience emotional flashbacks or cognitive distortions that are linked to that experience. These flashbacks are like sudden replays of past trauma, but they don’t just exist in the mind—they can show up physically in the body.


Neurotags, Emotional Flashbacks, and Chronic Pain

Think about it this way: When we experience a traumatic event, our nervous system reacts by encoding that event into a neurotag. This neurotag includes not only the physical sensations (like tightness, pain, or discomfort), but also the emotions (fear, anger, sadness) and cognitive patterns (thoughts like “I am unsafe” or “I am weak”).

Emotional flashbacks happen when the brain reactivates these neurotags, causing the body to respond as if the trauma is happening again. This is why someone with chronic pain may experience intense emotions that seem disproportionate to the physical sensations they’re feeling. The pain can trigger a flashback—a sudden, overwhelming re-experience of trauma that isn’t just mental but is felt deeply in the body.

In my case, the tension I experienced in my hips and lower back was a reflection of both the physical trauma of overtraining and the emotional trauma I had internalized from years of pushing myself too hard and ignoring my body’s signals. When my nervous system encountered stress, it activated these neurotags, making the tension and pain feel more intense and more pervasive. The more I resisted this pain or ignored the emotional connection to it, the worse it became.


How I’m Healing: Creating New Neurotags and Engaging the Vagus Nerve

Understanding neurotags has been revolutionary in how I approach my healing process. The key to healing, I’ve learned, is not simply “fixing” the physical pain but reprogramming the neurotags. This involves creating new patterns that support healing, safety, and relaxation.

One powerful way I’m rewiring my nervous system is by engaging the vagus nerve, the longest cranial nerve that plays a critical role in regulating the parasympathetic nervous system. The vagus nerve is like the body’s “brakes,” helping to turn off the fight-or-flight response and return the body to a state of calm. When activated, it encourages relaxation, emotional regulation, and recovery—exactly what my body needs as I untangle the tension stored in my fascia and nervous system.

Here’s how I’m starting to rewire my system:

Reconnecting with Joyful Movement:
I’ve reintroduced activities that make me feel alive, like walking in the garden or playing with my pets. These moments remind me that movement isn’t just about strength—it’s about freedom. By incorporating joyful, non-stressful activities, I’m helping to reinforce new neurotags that associate movement with pleasure and ease.

Reclaiming Safety Through Movement:
Instead of high-intensity workouts, I’ve shifted to gentle, functional exercises that strengthen my core and glutes while supporting my nervous system. Slow, mindful movements like glute bridges, bird dogs, and pelvic tilts have become my new best friends. These exercises not only build strength but signal to my nervous system that it’s safe to move.

Releasing Fascia with Love:
I’ve embraced somatic practices like gentle rocking, diaphragmatic breathing, and fascia-focused stretches to help release tension. These practices aren’t just physical—they’re a way of telling my body, “You’re safe now.” They help reprogram the neurotags associated with stress and trauma by sending a message of relaxation and calm.

Vagus Nerve Activation:
To support my nervous system’s recovery, I’ve incorporated practices that stimulate the vagus nerve, such as slow, deep belly breathing and humming. Breathing deeply into my diaphragm (focusing on long exhales) has been especially helpful in calming my body and signaling to my nervous system that it’s okay to relax. By consciously engaging my vagus nerve, I’m helping shift from the fight-or-flight response into a restorative state.

Rewriting Emotional Patterns:
Rewiring my nervous system also means rewriting my emotional patterns. This involves acknowledging the emotional flashbacks that arise when pain triggers old neurotags and consciously choosing to respond with compassion and self-care. Instead of reacting with fear or frustration, I’m learning to pause, breathe, and remind myself that I’m safe now.

What Chronic Pain Has Taught Me

Chronic pain has been a tough teacher, but it’s taught me lessons I wouldn’t trade for anything:

  • Your body is always on your side. Pain is a signal, not a punishment.
  • Healing isn’t linear. Some days, progress looks like resting instead of pushing.
  • Movement is medicine, but only when done with intention and love.

I share this journey because I know I’m not alone. So many of us carry the weight of trauma—both emotional and physical—in our bodies. And while the road to healing isn’t easy, it’s worth it.

If you’re navigating chronic pain, I want you to know this: Your body isn’t broken, and you don’t have to fight it. With the right tools, patience, and self-compassion, you can create safety, release tension, and rediscover the joy of movement.

I’m still on this journey, and I’d love to hear about yours. What has chronic pain taught you? How are you learning to trust your body again? Let’s keep this conversation going—because healing happens when we feel safe enough to share.
