Longer days and warmer nights. 

But the more I study the brain, the more I believe something deeper is happening.

Summer feels different because, for a few months each year, we accidentally reconnect with some of the conditions our brains evolved within:

We spend more time outside.
We move more.
We explore more.
We experience more awe.
We connect with other people.
We pay attention.

And when that happens, millions of us describe the experience in almost exactly the same way:

"I feel more alive."

In this episode of Next Door Neuro, I explore how summer may feel so meaningful because it gives our brains more of what they've been missing.

I discuss:

• How experiences of awe can change the way we think
• Why novelty and exploration are so powerful for the brain
• The connection between attention and memory
• How to carry a little bit of summer with you long after the season ends

Because the things that make us feel fully alive don't belong to summer.
They belong to us.

But neuroscience suggests we may be overlooking one of the most important ingredients for a healthy brain:
Other people.

In this episode of Next Door Neuro, I explore why social connection isn’t simply a nice addition to life, it’s one of the conditions the human brain evolved within.

You’ll learn:

• Why simply being with someone you trust can make your brain feel safer
• How conversations help us think more clearly and solve problems
• What the 85-year Harvard Study of Adult Development teaches us about health, resilience, and happiness
• Why summer naturally creates opportunities to reconnect, and why we should take advantage of them

Your brain doesn’t just need movement.
It doesn’t just need nature.
It needs people.

We’ve become incredibly good at filling every spare moment.

Productivity.

But our brains actually need periods of quiet, every day. 

In this episode of Next Door Neuro, I explore why simply sitting outside (without an agenda, to dos, or your phone) may be one of the most restorative things you can do for your attention, creativity, and mental clarity.

Drawing on research from environmental psychology and neuroscience, we’ll explore how nature helps restore directed attention, why the brain’s Default Mode Network is essential for reflection, and how moments of boredom and mind wandering can actually fuel creativity and better problem-solving.

This episode is part of my ongoing summer series exploring a simple idea:

The healthiest habits aren’t always the hardest. Sometimes they’re the ones the season, the weather, and your environment make easiest.

⸻

Studies & Concepts Mentioned

* Attention Restoration Theory (Stephen & Rachel Kaplan)
* Berman, Jonides & Kaplan (2008): The Cognitive Benefits of Interacting With Nature
* Default Mode Network (Raichle et al., 2001)
* Mind wandering, boredom, and creativity research

If you enjoy practical neuroscience that helps us thrive in everyday life, I’d love to have you join the conversation.

But it does so much more than that.

Morning light helps set your brain’s internal clock, shaping everything from your mood and energy to your sleep, metabolism, and hormone rhythms later that day.

And what I love about this habit is that it isn’t complicated:

No cold plunge.
No elaborate morning routine.
No expensive gadget.

Just stepping outside and letting your brain know the day has begun.

In this episode of Next Door Neuro, I explore:
- Why morning light may be one of the most underrated habits for brain health
- How your brain’s “master clock” coordinates sleep, mood, energy, and metabolism
- Why getting sunlight in the morning actually helps you sleep better that night
- The surprising connection between morning light, mood, and healthy cortisol rhythms
- Why summer is the perfect time to build this simple habit

Because health isn’t always about adding more or perfecting a routine.
It’s about restoring the conditions our brains evolved within.

Last week, we talked about the opportunities that longer days provide. This week, I wanted to dive deeper into one of the simplest (and most human) forms of movement: walking.

Walking isn’t just exercise.

It’s how we evolved.

And modern neuroscience is revealing just how profoundly something as simple as walking can influence our metabolism, creativity, stress, mood, and even long-term brain health.

In this episode, I explore:

• Why humans were born to walk
• Why a 10-20 minute walk after meals can improve blood sugar regulation
• How walking changes creativity and problem-solving
• Why walking in nature helps break stressful thought loops
• The connection between walking and long-term brain health
• Why summer might be the perfect time to build this habit

Because this summer, your goal shouldn’t be to “become a walker.”

It should be to remember that you already are one.

As we approach the summer solstice and the longest days of the year, I’ve found myself wrestling with a simple question:

What am I supposed to do with all this extra daylight?

Modern life makes it possible to live almost exactly the same way in June that we do in January. But our brains evolved in a world of changing seasons, and health isn’t just about maintaining the same routines year-round... it’s also about learning to work with the conditions around us.

In this episode, I explore:
☀️ How longer days influence our brains and circadian rhythms
🚶 Why small changes like morning light and evening walks can have outsized benefits
🧠 The tension between consistency and responsiveness
🌿 Why health may be less about optimization and more about restoring conditions our brains evolved to expect

The goal isn’t to overhaul your life because it’s summer.
It’s simply to leverage what summer is already giving you.

But the more I reflected on those conversations, the more I realized they were all pointing toward the same idea:

The quality of our lives is shaped less by our intentions than by our defaults.

Why do we instinctively reach for our phones? Why do we fall into habits we know aren’t serving us? And why do so many of us feel drawn to the novelty of nature, adventure, and deeper human connection?

In this season recap episode of Next Door Neuro, I explore the common thread running through this year’s conversations: the importance of intentionality in a world increasingly designed to run us on autopilot.

Drawing on insights from guests including outdoor educator Sarah Nielsen, Erica Mallery - coach and mentor for those looking to improve their relationship with alcohol, leadership coach Marcy Stoudt, adventurer Richard Campbell, and podcaster Dawn Wecker, I unpack what it means to pay attention, build better defaults, and create a life that reflects who we actually want to be.

Because the most important question we should be asking isn’t “How can I optimize my life?”

It’s simply:

“Is this the way I want to live?”

If you enjoy conversations about neuroscience, behavior change, mental health, human connection, and what it means to thrive in the modern world, I’d love to have you along for the journey.

In this episode of Next Door Neuro - Lab Notes, I explore a fascinating creativity study from researchers at UC Santa Barbara that challenged a common assumption:

When we're stuck, most of us instinctively try to work harder.
We stay at our desks longer.
Think more.
Push harder.

But what if that's exactly the wrong approach?

In this study, participants worked on a creative problem-solving task and were then assigned to different groups.
1. Some kept working.
2. Some rested.
3. Some completed a mentally demanding task.
4. And one group completed a simple, low-demand task that allowed their minds to wander.

Then all the groups went back to the creative problems they had been working on to start. The result?

The mind-wandering group improved their creativity scores by roughly 40%.

Not because they were consciously thinking harder about the problem.

But because stepping away appeared to give the brain room to continue processing information in the background.

In this episode, I explore:
• The surprising findings from the study  
• Why mind wandering may support creativity and insight  
• What happens when we continuously fill every empty moment with stimulation  
• How modern life may be reducing opportunities for our brains to do some of their best thinking  
• A simple strategy for approaching difficult problems more effectively

Importantly:

This isn't an argument against podcasts, music, technology, entertainment, or any other kind of stimulation.

It's a reminder that the brain may benefit from occasional periods of quiet.

Because sometimes the most productive thing you can do isn't to keep pushing.

It's to create enough space for your mind to wander.

In this episode of Next Door Neuro - Lab Notes, I explore an idea that has been sticking with me since my conversation with productivity coach Emily Guerra:

Many of us are treating ourselves like machines. And increasingly, modern life is training us to do exactly that.

More hours.
More output.
More optimization.
More efficiency.
More productivity.

But humans aren't factories, and brains don't work like industrial machines. Our attention fluctuates, our motivation shifts, our energy changes, our creativity ebbs and flows... and recovery following a period of output matters.

In this episode, I explore:
• Why modern culture increasingly equates productivity with value  
• How hustle culture shapes our expectations of ourselves  
• Why humans evolved in rhythms of effort and recovery  
• How productivity slowly becomes identity  
• Why many of us expect things from ourselves we'd never expect from another person  
• And why thriving may require reconnecting with our biological rhythms

Importantly, this isn't about lowering your standards... It's about recognizing that sustainable performance requires recovery.

Because we are biological organisms, not industrial machines.

04:20 – We are biological organisms

Why do so many of us feel guilty resting?

And why do moments that should feel restorative feel like we’re falling behind?

In this episode of Next Door Neuro - Lab Notes, I explore something I’m still actively working on myself: I don’t rest well.

Despite spending years studying neuroscience, stress, recovery, burnout, sleep, and performance… there is still a part of me that feels like slowing down means losing opportunities.

And I know I’m not alone. Many of us grew up watching people we admired constantly work. We celebrate busyness, exhaustion, grinding... we say:

“Hustle harder.”
“I’ll sleep when I’m dead.”

But increasingly, I wonder: what if many of us have been trained to associate rest with falling behind?

In this episode, I explore:
• Why guilt around rest is often social conditioning
• How hustle culture shapes our beliefs about productivity and worth
• Why humans evolved in natural cycles of effort and recovery
• How recovery supports learning, creativity, emotional regulation, and sustainable performance
• Why slowing down can feel uncomfortable, and why noticing that matters

Importantly: this isn’t about doing less, it’s about learning how to recover better.

Because recovery isn’t falling behind! Recovery supports thriving.

04:13 – Recovery supports performance
05:27 – Recovery isn’t falling behind
06:36 – Notice the guilt

In this episode of Next Door Neuro – Lab Notes, I explore a realization I’ve been having lately:

I’m slowly losing the ability to direct my own attention.
And I don’t think I’m alone...

Humans evolved in environments filled with quiet.
Downtime.
Stillness.
Boredom.

Those moments created space for thinking, reflection, creativity, and deciding what actually deserved our attention.

But modern life increasingly floods those same systems.
Notifications.
Email.
Social media.
News.

None of these things are inherently bad.

But increasingly, I wonder:
Are we choosing what we pay attention to?
Or is our attention increasingly being chosen for us?

Importantly, this isn’t about eliminating technology.

It’s about learning to notice the pull.
Because attention is trainable.
The brain adapts.

And reclaiming our ability to intentionally direct attention may be one of the most important skills we develop in modern life.

Timestamps:

00:55 – Humans evolved with quiet
01:56 – Our brains seek novelty
02:48 – We now live in abundance
04:43 – Attention shapes our experience
05:40 – Notice the pull
05:55 – Choose what deserves your attention

…but that many of the ways we’ve been taught to work are fundamentally misaligned with how the brain actually functions?

For a long time, productivity has meant:
- Doing more.
- Working longer.
- Checking more boxes.
- Pushing harder.

And honestly, for much of college and graduate school, I wore overworking like a badge of honor.

Minimal sleep.
16-hour days.
Constant stimulation.
Always feeling like I should be doing more.

But looking back at that time, I wasn't truly thriving.

I struggled to rest.
To think deeply.
To feel present.
To integrate what I was learning.
And eventually, I realized that productivity and fulfillment are not the same thing.

In this conversation, I sit down with productivity coach and founder of The Productivity Flow, Emily Guerra.

And what I appreciate about Emily’s approach is that she doesn’t just talk about getting more done, she talks about redefining productivity entirely.

We explore:
• Why modern productivity culture increasingly treats humans like machines
• How hustle culture has shaped our relationship with work
• Why rest, stillness, movement, and recovery are essential for focus and creativity
• How smartphones and constant stimulation impact dopamine, motivation, and attention
• Why many of us increasingly outsource emotional regulation to technology
• How small environmental changes can dramatically shift behavior
• And how to build a more intentional and sustainable relationship with work, technology, and ourselves

This conversation isn’t just about productivity.

It’s about attention, energy, presence, meaning, and how we live well inside environments that constantly pull at our brains.

In this episode of Next Door Neuro - Lab Notes, I explore one of the most important principles in neuroscience and addiction:

The brain creates the opposite of what you repeatedly use to change your emotional or physiological state.

Using caffeine as a personal example, I unpack why the brain “pushes back,” how repeated relief and stimulation can slowly shift our baseline, and why this idea may help explain everything from addiction… to compulsive phone checking… to why boredom suddenly feels so uncomfortable.

But importantly, this episode isn’t about fear or eliminating pleasure.

It’s about understanding how the brain adapts, and using that knowledge to work with your brain rather than constantly fighting against it.

In this episode, I explore:

• why the brain adapts and pushes back
• how repeated behaviors slowly shape what feels normal
• why modern environments make emotional regulation harder
• practical tools for interrupting automatic patterns
• rebuilding earned reward
• training stillness again
• and how small repeated actions can create meaningful change over time

If your brain fuels your life… what fuels your brain?

 07:34 – Rebuild earned reward
 08:58 – Train stillness again
 09:46 – Small repeated changes matter

In this episode of Next Door Neuro – Lab Notes, I explore one of the most important ideas from my recent conversation with neuroscientist and bestselling author Judy Grisel:

Addiction isn’t getting worse because humans suddenly became weak.

It's likely getting worse because the environment changed dramatically… while the brain stayed largely the same.

And importantly, this conversation isn’t just about drugs anymore.

It’s about modern life more broadly:

• Smartphones
• Social media
• Ultra-processed food
• Gambling
• Pornography
• Endless stimulation
• And constant access to quick relief, reward, and distraction.

In this episode, I explore:

• Why modern life may be becoming increasingly addictive
• “Supernormal stimuli” and evolutionary mismatch
• Why constant access changes behavior
• Why boredom feels increasingly uncomfortable
• Earlier exposure and adolescent brain development
• And the rise of behavioral addictions.

If your brain fuels your life… what fuels your brain?

In this episode of Next Door Neuro – Lab Notes, I unpack one of the most powerful ideas from my recent conversation with neuroscientist and bestselling author Judy Grisel:

The most important thing we can teach our kids about drugs may not actually be about drugs at all.

It’s about understanding how the brain responds to fast-acting, artificial relief.

Because increasingly, our modern world is built around instantly changing how we feel:
- social media
- pornography
- gambling
- ultra-processed food
- endless stimulation
- and increasingly potent substances

And while legislation and parental oversight matter, I believe we may be underestimating the power of education - especially helping people understand how the brain adapts to repeated artificial relief over time.

In this Lab Notes episode, I explore a framework I’ve found personally helpful:

“There’s no free lunch for your brain.”

The brain isn’t trying to make us happy all the time. It’s trying to keep us balanced. And because of that, the brain adapts to repeated highs, relief, stimulation, and escape - often creating more of the very state we were trying to avoid.

If your brain fuels your life… what fuels your brain?

Why Addiction Is Getting Worse | Judy Grisel

Judy Grisel is a neuroscientist, professor, bestselling author of Never Enough, and a former addict who now studies addiction and the brain. In our full conversation, we explore addiction, dopamine, modern life, and why the brain adapts the way it does.

In this episode of Next Door Neuro, I sit down with Judy Grisel - a behavioral neuroscientist, professor at Bucknell University, and nationally bestselling author who has spent decades studying addiction… while also living through it herself.

At 12 years old, Judy describes alcohol as: “the solution to a problem I didn’t know I had.”

What followed was a decade-long spiral through substance abuse, homelessness, expulsion from multiple schools, and profound despair - before eventually finding sobriety and becoming a neuroscientist focused on understanding addiction, reward, and the brain.

What makes Judy especially compelling isn’t just her scientific expertise. It’s the combination of deep neuroscience with lived experience.

In this conversation, we explore why addictive behaviors often begin as solutions… how the brain adapts in ways that trap us in destructive cycles… and why addiction may actually be getting worse despite decades of scientific progress.

We discuss dopamine and the brain’s reward system, why modern environments are amplifying addiction risk, how phones, pornography, gambling, and social media hijack the same neural pathways as drugs, and why adolescents may be especially vulnerable in today’s world.

We also dive into evolutionary mismatch, the limits of willpower, the importance of environment, and what recovery taught Judy about meaning, awe, challenge, and real-world fulfillment.

This conversation isn’t just about addiction.

It’s about how the brain learns, adapts, copes, and searches for relief in the modern world.

It’s that starting feels risky. And your brain is wired to treat that risk (especially rejection) as a threat.

In this Lab Notes episode of Next Door Neuro, I break down why something as simple as asking for a free coffee can feel so uncomfortable, and what that reveals about how your brain processes rejection.

More importantly, I walk through how to retrain that response so you can stop avoiding risk… and start taking action instead.

In this episode:

• Why your brain treats rejection like a threat (and where that comes from)
• How avoidance reinforces fear and keeps you stuck
• Why confidence and clarity don’t come before action - they come from it
• How exposure rewires your brain’s threat response over time
• Why most people never start (and what’s actually driving that hesitation)

Try this:

• Say it out loud: “I’m new to this - if I’m missing something, tell me”
• Create small “rejection reps” (ask for something slightly uncomfortable)
• Measure your reps - not your outcomes

In this episode of Next Door Neuro, I sit down with Mark Heckmann - multi-business founder and entrepreneurial coach - to explore what actually gets in the way when we try to start.

Mark has built companies across industries ranging from robotics and agriculture to AI and consulting. But what makes him especially interesting isn’t just what he’s built... it’s how he thinks.

He started with almost no resources… bartering websites for things like pizza… and built momentum by taking action before feeling ready.

Now, he helps others do the same.

In this conversation, we break down:

• Why most people never take the first step,
• How your brain interprets risk and rejection
• What actually changes when you stop waiting for certainty and start taking action.

We also get into one of the most powerful mindset shifts for me personally: reframing rejection not as failure, but as data. Because you’re not even in the game until you’ve heard 100 “nos.”

If your brain fuels your life… what fuels your brain?

In this episode:
• Why starting feels so difficult (even when the idea is clear)
• How your brain interprets risk, rejection, and uncertainty
• Why waiting for certainty keeps you stuck
• How to reframe rejection as useful data
• The role of repetition in building confidence
• Why autonomy changes how you think about work
• How to start something without massive resources
• The difference between planning and actually doing
• Why most people quit before they’ve even really started

But if your attention is on your phone, your brain is still operating like you’re indoors… and you’re missing a lot of what nature is actually doing for you.

In this Lab Notes episode of Next Door Neuro, I break down how your phone may be undermining the benefits of being outside - and why presence, not just location, is what actually matters. I explore why nature helps reduce stress, restore attention, and quiet rumination - and how those benefits can be lost if your attention is somewhere else. I also share two simple ways to start getting more out of the time you’re already spending outside.

In this episode:

• Why being outside doesn’t automatically reduce stress
 • How your phone keeps your nervous system “on”
 • What “soft fascination” is, and how it restores attention
 • How nature helps quiet anxiety and rumination
 • Two simple ways to get more out of time you’re already spending outside

Try this:

• Stand still longer than feels normal
• Pause before reaching for your phone

Being Outside Isn’t Enough - conversation with Sarah Nielsen

https://www.youtube.com/watch?v=OpXhaC7JQK0&t=10s

If your brain fuels your life… what fuels your brain?

In this episode of Next Door Neuro, I sit down with Sarah Nielsen, M.Ed, NBC-HWC, a health and outdoor educator and board-certified wellness coach, to explore why simply being outside isn’t always enough, and what it actually takes for nature to meaningfully impact your brain, body, and well-being.

We talk about how modern life has shifted us indoors, how screens now follow us everywhere, and why so many of us are technically “outside,” but still mentally somewhere else.  

Sarah shares how our phones are changing the way we experience nature - turning special moments into something we capture instead of something we actually feel - and what we’re missing as a result.  

We also explore the science behind why nature helps us feel better, from stress reduction and attention restoration to the sensory and emotional experiences that screens simply can’t replicate.

One of the biggest takeaways from this conversation:

You don’t necessarily need more time in nature.
 You need more presence when you’re there.

Sarah also introduces something critical: the idea of “sips of nature” - small, consistent moments of outdoor exposure that can meaningfully improve your stress, focus, and overall well-being.  

Key Topics:

• Why 93% of Americans spend most of their time indoors
• Why being outside isn’t enough if your attention is elsewhere
• How phones are changing our experience of nature
• What we miss when we’re not fully present outdoors
• Stress Reduction Theory & Attention Restoration Theory
• Why nature improves focus, mood, and brain function
• “Sips of nature” vs. all-or-nothing outdoor thinking
• Intrinsic vs. extrinsic motivation (and social media’s role)
• Why nearby nature and your “wild home” matter most
• Simple ways to bring nature into daily life

Get a great answer.

Maybe go a little deeper…

And in the moment, it feels incredibly productive.

Clear. Insightful. Like you’ve really learned something.

And then a few hours later… it’s gone.

Why does this happen?

In this Lab Notes episode, I break down the brain science behind why learning with AI often doesn’t stick, even when it feels like it should.

There are a few key mechanisms at play, including cognitive offloading (outsourcing the work of thinking), the difference between recognizing and generating information, and the lack of “desirable difficulty” that our brains actually need to learn. We also explore the fluency illusion - why something can feel clear in the moment without being deeply understood - and how instant answers may be disrupting dopamine-driven learning.

AI isn’t the problem. But the way we’re using it may be eroding how we learn. Over time, that creates a gap between what feels like progress… and what we can actually use in our day-to-day lives.

In this episode, I also share two simple ways to learn with AI instead of just consuming it:

• Think First, AI Second

• The No-Look Test

The goal isn’t to use AI less, it’s to use it in a way that actually builds your brain.

13:00 – The No-Look Test

14:30 – The real goal: learning that sticks

In this episode of Next Door Neuro, I sit down with Lori Robbins, Head of AI Strategy at Denison University and founder of Herizon AI, to explore how AI is reshaping not just how we work, but how we learn, reflect, and relate to other people.

We start with Lori’s experiment stepping away from AI for a week, and what it revealed about how quickly these tools have become embedded in our daily lives. From the frustration of going back to traditional search, to the deeper connection that comes from turning back to human experience, the conversation highlights both what AI gives us and what it might be taking away.

We explore why AI can feel like a “thought partner,” where that experience breaks down, and how instant answers may be altering the way we process, understand, and retain information. Lori also shares how these systems actually work, why they tend to agree with us, and what it means to use AI in a way that supports - rather than replaces - our own thinking.

We also discuss the growing role of AI in education, mental health, and companionship, and what it means for a generation growing up alongside this technology.

If your brain fuels your life… what fuels your brain?

In this episode:

• Lori’s AI-free experiment and what it revealed
• Why AI feels conversational, and why that matters
• The difference between AI-generated insight and human experience
• How instant answers can create the illusion of understanding
• The “Yes-Bot effect” and why AI often agrees with you
• AI, critical thinking, and the next generation
• The opportunities and risks of AI in mental health and connection
• Data privacy and what we share with AI tools

Within minutes, we’ve had dozens of tiny dopamine hits…

And somehow, the rest of the morning feels flat.

Why?

In this Lab Notes episode, I break down the neuroscience of dopamine - and why not all dopamine is created equal.

There’s a critical difference between earned dopamine and unearned dopamine, and understanding this difference can completely change how you think about motivation, energy, and focus in your daily life.

We live in a world filled with instant rewards (social media, ultra-processed food, constant notifications) and over time, these “easy” dopamine hits can actually reduce your baseline motivation and make meaningful work feel harder.

But there’s a better way!

In this episode, I cover:

• What dopamine actually does (it’s not just “pleasure”)
• Why “unearned rewards” can drain motivation over time
• How modern life is pushing us toward low-quality dopamine
• Why effort, challenge, and discomfort lead to better outcomes
• How to rebuild motivation through “earned rewards”

3 practical ways to rebalance your dopamine:

1. Create space between effort and reward
2. Add one daily “earned reward” anchor
3. Reduce one source of constant, easy dopamine

The goal isn’t less dopamine.

It’s better dopamine.

In this episode of Next Door Neuro, I sit down with Richard Campbell, founder of 10Adventures, to explore why so many people are drawn to adventure, nature, and challenge - and why these experiences may be far more important for our mental health, perspective, and sense of meaning than we realize.

We discuss why outdoor adventure isn’t about dramatic, life-changing epiphanies, but instead about small shifts in how we think, feel, and live. Richard shares what he’s learned from helping thousands of people step outside their normal routines, and we explore how challenge, movement, nature, and disconnection from modern life can help us feel more like ourselves again.

We also dive into evolutionary mismatch, the hidden psychological cost of modern convenience, why walking helps solve problems, how adventure can strengthen relationships, and what it means to build a life around what actually matters.

If your brain fuels your life… what fuels your brain?

In this episode, we cover:

• Why people crave adventure during major life transitions
• The simplicity people rediscover when they step away from daily life
• Why meaningful change tends to happen gradually, not all at once
• How modern environments may be pulling us away from what our brains are wired for
• Why walking, hiking, and time outdoors support stress reduction and clearer thinking
• The connection between challenge, discomfort, and feeling more alive
• How shared outdoor experiences can strengthen relationships
• Richard’s decision to leave a successful career at 40 to pursue a more meaningful path
• Why clarity often comes from stepping away rather than pushing harder

What if you could change your relationship with that voice, and see it for what it really is?

In this Lab Notes episode, I reflect on my conversation with Dawn Wecker (from the Dawnversations Podcast) and break down the neuroscience behind negative self-talk, rumination, and the identity loops that shape how we see ourselves.

You’ll learn:

• Why your brain is wired to focus on negative thoughts
• How this drives rumination
• Why modern life makes all of this worse
• How repeated thoughts become our identity over time

And most importantly, I’ll walk you through four simple techniques you can use immediately to create distance from that inner voice and take back control.

This isn’t about “just thinking positive.” It’s about understanding your brain, and learning how to work with it instead of against it.

If your brain fuels your life… what fuels your brain?

Key Moments:

00:00 – Meeting the voice in your head (“Carol”)

02:20 – Why self-criticism gets so loud

03:00 – The Default Mode Network and rumination

The next time that voice shows up, don’t fight it.

Just say: “I’m having the thought that…”

That one shift can put the voice in its place.

so why does it feel like something’s missing?

We talk more than ever.

We’re surrounded by people.

We have endless ways to communicate.

And yet, so many of us don’t feel truly heard or connected.

In this episode of Next Door Neuro, I sit down with Dawn Wecker to explore why real connection feels harder than it should, and what’s actually getting in the way.

Together, we unpack a simple but powerful idea:

The problem isn’t that we don’t want to connect.

It’s often that we’re not fully present when it matters.

In this conversation, we discuss:

• Why most people are listening while waiting to talk
• What it actually means to feel heard and validated
• How being stuck in your own head blocks real connection
• The role of your inner voice (“Carol”) in shaping interactions
• Why shared stories help us realize we’re not alone
• How even small moments of connection can create a ripple effect
• What it looks like to bring more presence into everyday conversations

At the core of this conversation the idea that:

Connection doesn’t come from being interesting.

It comes from being interested.

But what if those behaviors aren’t the problem. . .

and are actually the solution?

In this Lab Notes episode, I reflect on my conversation with Erica Mallery and unpack a powerful mindset shift:

• These habits exist because they reduce discomfort

• And your brain is wired to repeat what works

From a neuroscience perspective: discomfort activates the amygdala (our "fight or flight" brain region), and under stress, the prefrontal cortex (which helps regulate the amygdala) becomes less effective; together, this leads us to default to familiar, reliable relief.

That’s where habit loops form.

And that’s why trying to “replace” a problem behavior often fails. 
We're trying to replace a behavior that's actually working for us in the short term.

Instead, real change comes from building your ability to sit with the discomfort that remains once you remove the coping mechanism. 

In this episode, I walk through:
• The neuroscience of habit loops and negative reinforcement
• Why modern life makes discomfort easy to escape
• How “extinction learning” reshapes your brain’s response
• A simple, practical way to start (30–60 seconds at a time)

Try this today:

• The next time you feel discomfort, pause.

• Stay for 30 seconds.

• Notice what happens.

You’re not doing nothing.

You’re training your brain.

It’s about how you cope with stress, regulate your emotions, and navigate discomfort.

In this episode of Next Door Neuro, I’m joined by Erica Mallery, founder of ShameOver, to explore a more nuanced and compassionate approach to alcohol and behavior change.

Rather than framing alcohol as the problem, Erica offers a different perspective:

For many people, alcohol is a solution,

A reliable way to manage stress, emotional overload, and mental fatigue.

Here, we discuss:

• Why alcohol isn’t a moral or willpower issue
• How shame and judgment keep people stuck
• The role of identity in changing behavior
• Why all-or-nothing approaches often fail
• How to build awareness, self-trust, and sustainable change

At the heart of this conversation is a powerful reframe...

The challenge isn’t just what you’re doing,

It’s what that behavior is doing for you.

What if stress isn’t the problem?

Instead, what if the way we think about stress is what actually shapes how it impacts our health, performance, and overall well-being?

Most of us are taught to see stress as something to avoid. . . something harmful that wears us down over time. But research suggests a more nuanced (and empowering) reality.

In this episode, I walk through:

• A large-scale study showing how stress mindset is linked to long-term health outcomes
• Research from Stanford psychologist Alia Crum demonstrating how quickly stress beliefs can shift
• How your body responds differently to stress depending on your mindset
• Why two people can experience the same situation but have very different biological and psychological outcomes

I also explore what’s happening under the surface - from cortisol to DHEA - and how your mental framing of stress can influence resilience, growth, and performance.  

Most importantly, I talk about how to apply this.

I’ll walk you through a simple, practical way to start shifting your stress mindset in everyday life, something you can use in moments of pressure, overwhelm, or uncertainty.

A simple practice to try

When you notice stress building, take a moment and remind yourself:

• This stress is giving me the tools I need to succeed
• I’m growing because of this challenge
• I stress because I care

Start small. Practice in low-stakes moments. Build the skill so it’s there when it matters most.

This Lab Notes episode is designed to pair with my conversation with Marcy Stoudt, where we explore how emotional regulation and mindset shape leadership and performance.

It influences how you respond to stress, how you communicate, and the emotional tone you bring into every room.

In this episode of Next Door Neuro, I’m joined by Marcy Stoudt, founder of REVEL, a leadership advisory firm focused on helping organizations grow without losing their identity.

We explore a more human approach to leadership, one grounded in self-awareness, emotional regulation, and intentional presence.

In this conversation, we discuss:
 • What authentic leadership really means in practice
 • Why leadership starts with regulating yourself, not controlling others
 • How “victim loops” shape behavior and limit growth
 • Why adapting your leadership style can strengthen (not weaken) authenticity
 • How small mindset shifts can unlock better performance and connection

At the core of this conversation is a simple idea:

Leadership isn’t about controlling the room. . . it’s about regulating yourself inside it.

It shapes how you focus at work, how you respond to stress, how patient you are with the people you love, and how effectively you make decisions. And yet, despite how central the brain is to everything we do, most of us rarely think intentionally about how to support it.

Modern life quietly works against brain health. We spend more time indoors under artificial light, more time on screens designed to capture our attention, and more time under chronic stress. At the same time, many people struggle to get consistent sleep, access nourishing food, move their bodies regularly, or spend time in nature.

Over time, these forces slowly deplete the brain’s capacity, making it harder to show up as the person we want to be.

Considering this, Next Door Neuro explores a simple question:

If our brains fuel our lives, what can we do to fuel our brains?

Hosted by neuroscientist and wellness coach Jamey Maniscalco, the podcast features conversations with scientists, health & wellness practitioners, and thoughtful leaders exploring how the brain works and how we can realistically support it in the modern world.

Each episode translates neuroscience into simple ideas and practical habits that help restore clarity, resilience, and emotional steadiness in everyday life.
