Welcome Back to season 15 of the Neuroscience Meets Social and Emotional Learning Podcast. I'm Andrea Samadhi, and on this podcast, we bridge the science behind social and emotional learning, emotional intelligence, and practical neuroscience so we can create measurable improvements in well being, achievement, productivity and results. And this season, season 15, we're exploring what I call the brain's operating system for human performance. Instead of looking at neuroscience, health, learning, motivation, and emotional intelligence as separate topics, like we did for the past 14 seasons, we're exploring how these systems come online in sequence. Each phase builds on the one before it. In phase one, we covered regulation and safety, and we asked the question, is the nervous system safe enough to learn? Then in phase two, where we are right now, we're covering neurochemistry and motivation, and we ask the question, what drives our behavior, our focus, and our sustained effort? Then we'll go on to phase three, movement, learning and cognition. Phase four, perception, emotion and social intelligence. And end with phase five, integration, insight, and meaning. And by the end of this year, my hope is that we can step back and ask, where am I out of alignment? Is it with my regulation or my thinking? Is it my focus or my belief? Is it how I'm learning or connecting with others? Or do I need some more work on integration, insight, and meaning? Because once we can see our gap, we can begin to close it. So the goal is not more effort. It's about better alignment. And when these systems are aligned, effort feels easier, learning becomes faster, and results become more consistent. Because peak performance isn't about doing more. It's about aligning the systems that drive our results. And just a recap of where we've been. On episode 392, we introduced the motivation loop and explored how the brain decides what's worth doing. Then we went on to episode 393, where we looked at how our beliefs trigger our neurochemistry that drives our actions, gives us feedback, and then repeats. Then episode 394, we looked at how our thought patterns impact our neurochemistry and Our Results with Dr. Carolyn Leaf. Then we moved on last week to episode 395, reviewing Dr. John Medina's work on theory of mind. And we explored something equally important, that the brain pays attention to what it believes matters. And Dr. Medina showed us that attention and reward are deeply connected. When the brain predicts something will be valuable, relevant or meaningful, attention increases. And when attention and reward align, that's when our learning improves. When our memory strengthens, our motivation increases and our behaviors become repeatable. But that leaves us with an important question. What creates the sense of reward in the first place? What makes the brain continue pursuing something? What makes us stay motivated? And what makes us lose interest? And why can effort sometimes feel rewarding and other times feel exhausting? So to answer these questions, we're turning to Dr. Anna Lemke, the author of the book Dopamine Nation, who we first Met September of 2021 on episode 162. Her work helps to explain the neurochemical engine underneath the motivation loop that we've been covering. While Dr. Medina helped us to understand how attention and Reward Influence Learning, Dr. Lembke helps us to understand why the brain seeks reward, how dopamine drives our motivation, why pleasure and pain operate on the same neural system. And what happens when. When the balance gets disrupted. Because the real goal isn't simply just about feeling good. The goal is to understand how the brain learns to associate effort with reward. And when that happens, something powerful occurs. Effort itself becomes rewarding. And that's where sustainable motivation begins. So let's see what Dr. Anna Lemke has to say about the neuroscience of pleasure and pain. And in this clip, Dr. Lembke explains one of the most important concepts in modern neuroscience. Pleasure and pain are processed in the same brain system and work like opposite sides of a balance.

Why it's non trivial is to understand the neuroscience of pleasure and pain. And the way that I explain this to my patients and to my medical students is, as I say, imagine that in your brain there's a balance, kind of like a teeter totter in a kid's playground. And in its resting state on the unlike a teeter totter in a kid's playground, that balance is level with the ground. That balance represents how our brain processes pleasure and pain, and they work like opposite sides of a balance. When we do something pleasurable or reinforcing, let's say in my case, I eat a piece of chocolate, my balance tilts slightly to the side of pleasure. I get a little release of dopamine, our pleasure neurotransmitter in the brain, and I feel good. But one of the overriding rules governing this balance is that it wants to stay level. It doesn't want to remain very long to the side of pleasure or the side of pain. So the brain will immediately respond to that or adapt to it by down regulating our own dopamine production.

Some key takeaways and how to put them into action. From clip 1 takeaway 1 the brain is always seeking balance. Dr. Lemke explains that Pleasure and pain are not separate systems. They operate like opposite sides of a seesaw. When we repeatedly tip the brain towards pleasure and you can see an image in the show notes with some examples like eating chocolate or shopping or using social media, the brain compensates by tipping towards pain to restore the balance. So a brain rule, every pleasure has a neurobiological cost. So how do we put this into action? Ask yourself, where am I? Getting large rewards for very little effort. Examples might include using social media, eating sugar, constant news consumption, streaming or online shopping. The goal isn't to eliminate pleasure. The goal is just with our awareness, because what we measure, we can begin to manage takeaway. 2. Over consumption changes the brain. What feels exciting today becomes normal tomorrow. The brain adapts to repeated dopamine spikes through a process called neuroadaptation. And over time, rewards feel weaker, cravings increase, motivation decreases, and more stimulation is needed to create the same feeling. So how do we put this into action? Choose one highly stimulating habit and and observe it for a week. Notice how often you engage in it, what triggers it, and how do you feel afterwards. Simply collecting data can reveal patterns that you didn't even know existed. Takeaway 3. Not all dopamine is created equally. There's borrowed versus earned dopamine, and we've covered this topic previously. Dr. Lemke's pleasure versus pain balance helps to explain an important distinction. We've got borrowed dopamine that comes before effort, like scrolling on social media or an energy drink before a workout, or sugar when you're stressed. These rewards feel good immediately, but because they require little effort, they often weaken motivation over time. The brain begins expecting reward before the work. Then there's earned dopamine. Dopamine that comes after the effort. Examples include finishing a difficult workout or completing a challenging project, or climbing to the summit of a hike, or finishing a podcast episode. For me, learning a new skill or solving a difficult problem, these rewards feel different. The brain learns that effort leads to reward, and over time, effort becomes rewarding. And this strengthens the motivation loop. So how to put this into action? Ask yourself, where am I borrowing dopamine? And where am I earning it? And for the next week, look for opportunities to delay rewards until after effort. So instead of checking your phone before starting work, complete one task first. Or instead of rewarding yourself before your workout, reward yourself after the workout. Or instead of seeking immediate comfort, lean into small challenge. And each time you do this, you're teaching your brain reward follows effort, and that's how motivation becomes sustainable. Takeaway 4. Temporary abstinence reveals the truth. One of Dr. Lemke's most powerful strategies is taking a break from a highly rewarding behavior. When we step away from constant stimulation, the brain's reward system has an opportunity to recalibrate. Only then can we see whether a behavior is serving us or controlling us. So to put this into action, try a short experiment. Choose one behavior that may be overstimulating your reward system and reduce it or eliminate it temporarily. And notice your energy, your focus, motivation, mood, and your cravings. This goal isn't punishment. It's just information takeaway. 5. Lasting change requires systems, not willpower. Many people believe success comes from discipline alone. And Dr. Lemke argues that creating the right environment is often more powerful. Instead of relying on willpower every day, create barriers that make unwanted behaviors harder to access. So to put this into action, ask yourself, how can I create more friction between myself and temptation? Examples easy ones include turning off notifications on your phone, keep unhealthy foods out of sight, and schedule device free time in your day. Small environmental changes produce large behavioral results. Moving on to clip two, how chronic overstimulation creates a dopamine deficit state. This is when the motivation loop breaks. In this clip, Dr. Anna Lemke explains why many people struggling with depression or anxiety or insomnia, low motivation or emotional distress may actually be experiencing the consequences of chronic overstimulation. Her first recommendation is surprisingly simple. She says, remove your drug of choice for a period of time. And the drug isn't necessarily alcohol or drugs. It can be anything, like social media, gaming, shopping, sugar, whatever it is, or any behavior that repeatedly floods the brain's reward pathways. And Dr. Lemke explains that people often feel worse before they feel better because the brain has adapted to the high levels of dopamine stimulation. When the stimulation is removed, the brain temporarily experiences a withdrawal like symptoms as it works to restore balance. And over time, the brain's pleasure pain system recalibrates, allowing people to experience pleasure from ordinary, everyday rewards again. And her larger message is that we live in a society with unprecedented access to pleasure, and many of us have unintentionally shifted our pleasure pain balance toward pain. And the solution is not necessarily more pleasure. It's restoring that balance.

We're walking around unhappy. I see so many patients coming in reporting depression, anxiety, insomnia, wanting me to help them. One of the first interventions that I make is to have them eliminate their drug of choice, whatever it is, for one month. And I warn that they're going to feel worse before they feel better, because it'll be the pleasure pain balance tilted here. But if they can just abstain for long enough, those neuroadaptation gremlins will hop off, the balance and homeostasis will be restored, and they'll again be able to take pleasure in life's more modest rewards. So ultimately, the thesis of Dopamine Nation is that both as individuals and as a larger society, we have inundated ourselves with so much dopamine that we reset our pleasure pain pathways to the side of pain, making it harder for us to experience pleasure and more likely that we will experience pain.

Some key takeaways from clip number two Take away one Feeling worse can be a sign of healing One of the biggest misconceptions around behavior change is that improvement should feel good immediately, and the brain doesn't work that way. When a highly stimulating behavior is removed, cravings increase, discomfort rises, and mood may temporarily decline. And this is often the brain recalibrating rather than it feeling. So to put this into action when reducing an overstimulating habit, don't judge success by how you feel in the first few days. Instead, ask yourself, could this discomfort be evidence that my brain is adjusting? And sometimes the discomfort isn't a sign that you're moving backward, it's a sign that you're recovering and moving forward. Takeaway 2 the brain adapts to excess dopamine the brain is remarkably efficient. When exposed to constant stimulation, it reduces its sensitivity to reward. What once felt exciting becomes normal. What once felt normal may eventually feel boring. And this is why people often need more stimulation to achieve the same feeling. To put this into action, identify what it is that's your drug of choice and ask yourself, what do I consistently turn to when I'm stressed? When I'm bored, anxious, or uncomfortable? We've got lots of examples, and awareness creates your choice. Takeaway 3 Modern life makes overstimulation easy. This is one of the central themes of her book Dopamine Nation. For most of human history, pleasure was scarce. But today entertainment is unlimited. Food is always available, social media never stops. Information is endless. The challenge is not about finding pleasure. The challenge is regulating our access to it. So to put this into action, look for places where you can create friction between yourself and whatever it is you're tempted. With lots of examples we've talked about already. Turning off notifications on your phone, keeping unhealthy foods out of sight, limit your screen time and create boundaries around technology use. Small barriers can create some significant behavioral Change and Takeaway 4. Sustainable motivation lives near our baseline and the goal isn't to feel intensely excited all the time. The goal is to restore the ability to enjoy ordinary rewards like learning, exercise, relationships, progress, achievement. These are the rewards that sustain long term motivation. To put this into action, reconnect with activities that once felt naturally rewarding to you. Ask yourself about the activities you enjoy, like reading, walking, meaningful conversations, learning something new or creative work. And as the reward system recalibrates, many people discover these activities become enjoyable again if the pleasure for them had disappeared and takeaway. 5. Doing hard things strengthens the brain and One of the most exciting findings in neuroscience that we've talked about before on this podcast involves the anterior mid cingulate cortex, or the amcc. Sometimes we call it the doing the hard things circuit. And this region appears to strengthen. When we voluntarily engage in difficult activities, things like exercise or learning challenging skills, delaying gratification, difficult conversations or endurance challenges. The brain learns, I can handle discomfort. So to put this into action, ask yourself each morning, what is one hard thing I can do today? On purpose? Because we've learned that doing hard things is valuable. Every time you choose effort over comfort, you're strengthening the circuits that support resilience, persistence and long term motivation. So to review and conclude this week's episode 396, clip number one taught us that pleasure and pain share the same neural circuitry. Clip two teaches us what happens when our balance is disrupted. And the lesson isn't that pleasure is bad. The lesson is that when pleasure becomes too easy and too abundant, the brain stops valuing effort. And when we reduce overstimulation, embrace manageable discomfort, and begin earning our dopamine instead of borrowing it, something remarkable happens. Our motivation returns, our effort feels worthwhile, and the motivation loop begins working the way it was designed to work. And as we close out today's episode, let's return to our phase two roadmap. If you're looking at the graphic, you'll notice Dr. Lemke sits right in the center. And that's intentional because everything we've covered so far in phase two flows through this central motivation system. We began with Bob Proctor with the power of belief. Belief creates expectation. Expectation shapes what we think is possible. Then we went to Dr. Carolyn Leaf, who showed us how our thoughts influence our neurochemistry. The thoughts we repeatedly think shape the chemical signals that influence our behavior and our performance. Then last week, Dr. John Medina helped us to understand attention and reward. The brain pays attention to what it believes matters, and what gets rewarded gets repeated. And today, Dr. Anna Lemke helped us to explain the missing piece. She showed us that dopamine is not just simply about pleasure, it's about motivation. It's about anticipation and it's about pursuit. And ultimately, it's about what the brain decides is worth the effort. When dopamine becomes disconnected from effort through constant simulation and easy rewards, the motivation loop begins to break. But when reward becomes connected to effort, to challenge, to growth and progress, the loop strengthens. And that's where sustainable motivation begins. And one final insight from today's episode. Dr. Lembke's work helps to explain why doing hard things matters so much. Every time we choose effort over immediate gratification, every time we choose growth over comfort, every time we voluntarily do something difficult, we strengthen the brain circuits that support persistence, resilience and long term motivation. The brain begins learning that effort is worth it. And eventually effort becomes rewarding. And that's when motivation becomes self sustaining. Not because the work gets easier, but because the brain learns that effort itself has value. And Dr. Anna Lemke isn't just another stop in the loop. She's the core motivation system that sits at the center of everything. But there's still two more pieces left to cover in this motivation loop that we haven't explored yet. Next week we'll move on to Dr. Chuck Hillman with movement, motivation and brain Activation. We'll explore how exercise activates the brain, why movement improves attention and learning, the connection between physical activity and motivation, how movement strengthens cognitive performance, why action often comes before motivation, and how movement helps to keep the motivation loop moving forward. Because in phase two, we're not just asking what makes effort feel worth it, we're also asking what helps us to take action once our motivation is present. And Dr. Chuck Hillman's research shows that movement may be one of the most powerful ways to activate the brain for learning, performance and sustained effort. Until next time, I'm Andrea Samadhi reminding you that when we understand how the brain works, we can align our thoughts, our emotions, our our behaviors and actions to create measurable improvements in well being, achievement, productivity and results. Thanks for listening. We'll see you next week.
