    About this Episode

    In this episode, my guest is Robert Malenka, MD, PhD, a professor of psychiatry and behavioral sciences at Stanford School of Medicine who has made numerous seminal discoveries of how the brain changes (neuroplasticity) in response to learning and in response to rewarding and reinforcing experiences. We discuss the brain’s several reward systems involving dopamine and serotonin and how these motivate us to seek out specific behaviors and substances. We discuss how these reward systems are modified based on context and our memories, and how they can be hijacked toward maladaptive drug seeking in addiction. We also explore how reward systems influence social connections, oxytocin and empathy and how that applies to our understanding of autism spectrum disorders. This episode should be of interest to those interested in neuroplasticity, social bonding, addiction, autism, learning and motivation. For the full show notes, visit hubermanlab.com.

    📝 Podcast Summary

    The Role of Dopamine in the Brain's Reward Circuitry and its Impact on Behavior

    Dopamine plays a crucial role in the brain's reward circuitry and its ability to assign value to our experiences. Dopamine is a neuromodulator that serves as a chemical signaling messenger in the brain, mediating a wide range of actions. Its primary function is in the brain's reward circuitry, which involves different parts of the brain communicating with each other. The release of dopamine is closely linked to the pursuit of pleasure and the motivation to seek certain types of experiences. Dr. Robert Malenka's research has shown that seeking out specific forms of pleasure, whether healthy or not, can alter the functioning of the reward circuitry and impact how dopamine is released and affects the brain. Understanding dopamine's role can greatly enhance our understanding of brain function, neuroplasticity, and rewards.

    The Role of Dopamine in the Brain's Reward Circuitry

    Dopamine plays a crucial role in the brain's Reward Circuitry, which alerts us to what is reinforcing or rewarding in our environment. This mechanism is essential for our survival as it helps us identify stimuli that are important or dangerous. Sugary, high-fat foods, sexual experiences, or even warmth when we're cold are all examples of stimuli that activate dopamine release in the brain. The dopamine neurons responsible for this are located in a region called the ventral tegmental area (VTA) and send messages to the Nucleus Accumbens, a key area in the Reward Circuitry. While the exact mechanisms of dopamine's effects are not fully understood, its release in the Nucleus Accumbens is associated with rewarding experiences.

    The Role and Complexity of the Dopamine System in Response to Rewards and Aversive Stimuli

    The dopamine system, specifically the Reward Circuitry, plays a crucial role in our response to important and salient events in our environment. It is closely tied to our arousal system and memory systems. Dopamine is not only released during pleasurable experiences like eating delicious food or engaging in rewarding activities, but also during aversive or painful stimuli, signaling their significance for our well-being. Context is also a critical factor in the dopamine system's response. For example, the anticipation of a full donut may result in more dopamine release compared to just a small piece. Additionally, our physiological state and personal goals can influence how we perceive and respond to rewards. Despite its seemingly simple nature, the dopamine system is incredibly complex, constantly integrating multiple reward contingencies and adapting to our ever-changing environment.

    The Influence of Context and Experience on Brain Response and Perception

    Our brain's response to certain stimuli is heavily influenced by context and our previous experiences. Robert Malenka explains that our memory system communicates with our reward circuitry, creating anticipation and cravings. However, in a different context, the same cues may elicit a different response. Our brain has the ability to rapidly change its perception, as seen in situations where someone we love can suddenly become aversive. The prefrontal cortex plays a crucial role in setting rules and scaling our reward responses based on the context. It acts as an executive function area, connecting with other structures such as the amygdala and Nucleus Accumbens. Our brain's complexity and the interplay of various regions contribute to our behavioral and emotional experiences.

    The Complexities of the Dopamine System and its Impact on Love, Addiction, and Motivation

    The dopamine system plays a crucial role in our experiences of love, arguments, reconciliation, and addiction. It is fascinating to see how a simple molecule can shift the perception of rewards and motivations within minutes. However, understanding the complexity of this system is a challenge. While podcasts like Andrew Huberman's have made neuroscience accessible to a lay audience, it is important to recognize that these explanations are oversimplifications. The dopamine reward circuitry is influenced by various factors such as context, history, and personal experiences. This complexity is what makes addiction a difficult issue to address, as different substances and behaviors have varying degrees of addictive liability. While substances like cocaine and opioids have high addictive potential, everyday habits like caffeine consumption may cause tolerance but not severe addiction. Understanding the intricacies of the dopamine system can help enhance mental well-being and potentially mitigate addiction-related problems.

    The Impact of Dopamine Release and Route of Administration on Addiction

    The addictive liability of a substance is influenced by both the amount of dopamine released in the brain and the speed of dopamine release. It is not solely the drug itself that determines addiction, but also the route of administration. Different routes, such as snorting, smoking, or injecting, result in varying experiences and levels of dopamine surge in the reward circuitry. For example, crack cocaine and methamphetamine, which rapidly enter the brain when smoked or injected, can create intense and compulsive urges to use again, despite not necessarily providing a pleasurable feeling. These highly potent substances can overwhelm the brain's natural capacity to handle such powerful stimuli. Overall, addiction involves neuroplasticity, which may modify neural circuitry, making a range of drugs or experiences more attractive.

    Understanding the Complexities of Addiction and the Brain's Reward Circuitry

    Addiction is a complex combination of underlying genetics and environmental factors that modify the Reward Circuitry in the brain. The use of substances like drugs of abuse can cause powerful changes in the synapses and activity of dopamine neurons and the Nucleus Accumbens, which are involved in the Reward Circuitry. These changes can last for several days or weeks and contribute to an increased propensity for addiction. However, not everyone who uses drugs or engages in addictive behaviors develops an addiction problem, indicating that other factors such as access to healthy outlets and alternative sources of satisfaction can play a role in addiction susceptibility. Additionally, engaging in activities like exercise can have a positive impact on the brain's Reward Circuitry, providing a healthy alternative to addictive substances or behaviors.

    Understanding the Complexities of Addiction: Biological and Environmental Factors at Play

    Addiction can cause changes in the brain that may last for a few days to a week or two. These changes can become stronger and last longer with repeated exposure to drugs like cocaine. However, the reason why some people can use these substances without developing a serious problem while others are heavily affected is still unclear. It is important for young people to consider the risks before deciding to experiment with substances. There is a wide variation in people's response to drugs, with some experiencing a euphoric effect and others not being affected at all. Genetic factors and family history also play a role in addiction. Additionally, the availability of substances influences addiction rates. Overall, addiction is a complex issue influenced by both biological and environmental factors.

    The crucial distinction between "wanting" and "liking" in addictive behaviors.

    The distinction between "wanting" and "liking" is crucial in understanding addictive behaviors. While something may be highly reinforcing, it may not necessarily be enjoyable or rewarding. This is evident in examples such as cocaine, which can be highly reinforcing but not necessarily enjoyable. Similarly, individuals may desire someone or something, but not necessarily like or enjoy them. The power of addiction lies in the ability to dissociate wanting from liking. Programs like 12 Step aim to create rewards around abstaining from addictive substances or behaviors, helping individuals develop a liking for sobriety while reducing the wanting for the addictive substance. Understanding the neural mechanisms behind this dissociation is vital in developing successful addiction treatment strategies.

    Mechanisms of Action and Effects of Different Drugs on the Brain

    Different drugs, such as cocaine, methamphetamine, and opioids, have distinct mechanisms of action in the brain. Cocaine and methamphetamine prevent the reuptake of dopamine, leading to increased dopamine levels, while opioids indirectly increase the activity of dopamine neurons, resulting in a larger release of dopamine. These drugs all have an effect on the reward circuitry, particularly the nucleus accumbens, by causing dopamine release. However, they produce different subjective experiences due to their actions throughout the brain. It is important to recognize that all drugs are not identical, even within the same class. Understanding these differences can shed light on the addictive liability and subjective effects of various substances.

    The Journey Towards Self-Confidence: Overcoming Self-Doubt and Finding Success

    Confidence and belief in oneself is a gradual process that develops over time. Robert Malenka, despite his successful career in neuroscience, initially struggled with self-doubt and insecurities. It wasn't until he gained experiences and worked with passionate individuals that he began to trust his ideas and voice his opinions. Through vigorous arguments and the development of a thicker skin, Malenka's confidence grew during his postdoc years and continued to evolve throughout his career. This gradual buildup of confidence allowed him to realize his potential and contribute to scientific research. The takeaway emphasizes that self-doubt is common, but with perseverance and experiences, one can overcome it and find success.

    Respectful and Individualized Approach to Autism Spectrum Disorder (ASD)

    The understanding and terminology around autism spectrum disorder (ASD) should be approached with sensitivity and respect. ASD is a complex and heterogeneous disorder, which means that it manifests differently in individuals. While some may prefer to be viewed as having a different style of living and interaction rather than a "disorder," it is important to provide support and research for individuals who require help, especially children with severe impairments. The terminology used should be based on individual preferences and respect for diversity. Ultimately, the focus should be on understanding and assisting individuals with ASD in their unique experiences and challenges.

    The Science of Social Behavior and Its Impact on Mental Health

    Social interactions and the desire for human connection are hardwired in our brains and are highly rewarded. Robert Malenka explains that the circuits in the brain that mediate our desire to spend time with others are built-in but also modifiable. This innate drive for social behavior is crucial for the survival and well-being of social species like humans. The dopamine Reward Circuitry plays a significant role in reinforcing social experiences and activities. Robert's research shows that the brain's reward system changes in models of depression and addiction, affecting our ability to experience pleasure and reward. Understanding the molecular mechanisms behind social behavior and the involvement of neurotransmitters like dopamine and serotonin can provide insights into mental health conditions and help improve the well-being of individuals living with them.

    The Role of Oxytocin, Dopamine, and Serotonin in Positive Social Interactions.

    Oxytocin, dopamine, and serotonin, three important neuromodulators, play significant roles in positive social interactions. Oxytocin, commonly known as the "love neuropeptide," is released during positive social interactions and promotes sociability. It influences the release of serotonin in the Nucleus Accumbens, a reward circuitry area, and contributes to reinforcing the rewarding aspect of social interactions. Additionally, oxytocin can modulate dopamine neuron activity in the ventral tegmental area, suggesting a connection between oxytocin and dopamine release during non-aggressive social interactions. It is crucial to understand that these neuromodulators do not work in isolation, but rather interact and influence each other. Further research is needed to elucidate the complex interplay between oxytocin, dopamine, and serotonin in social behavior.

    The Brain's Complex Function and the Role of Serotonin, Oxytocin, and Dopamine in Social Interactions

    The brain's function is not as simple as turning on dopamine and turning off serotonin. It is a complex process that involves the weighting of inputs. Serotonin and oxytocin, along with dopamine, play prominent roles in social interactions and the Nucleus Accumbens is an important structure in mediating these interactions. Within the Nucleus Accumbens, there are neurons that act as accelerators and brakes, promoting or inhibiting certain behaviors. This structure rewards certain behavioral options while reducing the probability of other actions. It influences our choices and plays a crucial role in pro-social, non-aggressive, and non-sexual interactions. Furthermore, it may also be involved in empathy.

    The Importance of Social Interactions in the Brain's Reward Circuitry

    The brain's reward circuitry is tuned to prioritize social interactions. While the exact mechanisms and detailed understanding of how it all happens are still unknown, the study of this circuitry has led to the development of potential treatments for individuals with Autism Spectrum Disorder and difficulties in pro-social interactions. The rewarding nature of social interactions has deep evolutionary roots, serving purposes such as reproductive success, protection against predators, and child-rearing. Despite the changing societal needs where physical protection may be less relevant, the brain's circuitry for social reward remains because it still serves important functions in our lives. Understanding and manipulating this circuitry can contribute to improved mental health and overall well-being.

    The Importance of Friendships and the Impact of Social Media on Connection

    Feeling connected to others is an essential aspect of our well-being. Robert Malenka emphasizes the positive aspects of friendships and how they provide emotional support and buffering against loneliness. Andrew Huberman highlights the impact of social media on our sense of connection, acknowledging its addictive qualities and its ability to activate our brain's reward circuitry. While social media can serve as a platform for interaction and communication, it cannot replicate the delight and energy increase experienced during in-person interactions. The conversation raises concerns about the detrimental effects of excessive social media use, particularly among socially isolated individuals. It underscores the importance of recognizing and addressing these issues as individuals, parents, and as a society.

    The Exploitation of Brain Reward Circuitry: Social Media, Gambling, and Drug Use

    Social media, gambling, and drug use all exploit the reward circuitry in our brains. While there can be positive uses of social media and enjoyable experiences with gambling, these activities also come with risks and potential harm. Social media can lead to social isolation and bad decision-making, while gambling can be addictive and financially damaging. The intermittent rewards provided by these activities make them especially powerful and difficult to resist. Additionally, the conversation touches on the topic of empathy and its role in positive social interactions. Understanding and practicing empathy can contribute to more meaningful and pro-social connections with others.

    The importance of empathy and compassion for the survival and well-being of humanity.

    Empathy and compassion are essential for the survival and well-being of the human species. Despite our differences in appearance or beliefs, understanding that we share a common humanity is crucial. When another person is suffering, it is important to have compassion and a willingness to help, just as we would for our close friends or loved ones. Robert Malenka explains that empathy has evolutionary significance and can even be observed in more primitive organisms like mice. By studying the neurobiological underpinnings of empathy, researchers can gain insights into how it can be enhanced in humans. This understanding can contribute to efforts aimed at promoting empathy and compassion in society.

    The Impact of Social Interactions on Pain Perception and Relief

    Social interactions and communication can have a significant impact on pain perception and relief. Both the speakers discuss the phenomenon of social buffering of pain, where being in a socially engaged environment can alleviate pain symptoms. They also explore the idea that humans secrete molecules, including odorants, which may act as analgesics. Furthermore, they discuss the importance of social cues, such as nods and positive gestures, in boosting motivation and intrinsic drive. The conversation also highlights ongoing research on the social transfer of pain and analgesia in mice, indicating potential behavioural antecedents of empathy. The connection between the anterior cingulate cortex and the nucleus accumbens in empathy-related brain mechanisms is also discussed. Overall, the conversation emphasizes the link between social interactions and pain relief, shedding light on possible therapeutic approaches and the role of neuromodulators.

    Encouraging Empathy and Compassion through Behavioral Paradigms and Contextual Factors

    The amount of empathy and compassion in the world can be increased by introducing behavioral paradigms that incentivize helping others. The discussion highlights the impact of personal challenges and struggles on inhibiting empathy and compassion. By considering the convenience or inconvenience of helping others, individuals can be motivated to prioritize their actions based on the circumstances. The conversation also touches on the influence of familiarity, hierarchy, and past interactions in determining compassionate behavior. The potential role of neuromodulators like serotonin, dopamine, and oxytocin in mediating empathic behaviors is also mentioned. Overall, the key takeaway here is that creating frameworks that take into account contextual factors can encourage greater empathy and compassion in individuals.

    Understanding the Impact of Autism on Social Interactions

    Autism involves a restructuring of the reward system around social interactions. Some individuals with autism may experience a lack or reduced reinforcement from social interactions, making it less rewarding for them compared to other activities. However, it is important to note that autism spectrum disorder is highly heterogeneous, and not all individuals with autism have the same experiences or symptoms. Research studies, both in humans and animal models, have suggested that the reinforcing component of social interaction is lacking or reduced in some individuals with autism. Additionally, there is ongoing research exploring the potential therapeutic use of oxytocin and other neuropeptides to enhance social interactions in individuals with autism.

    The Addictive Liability of MDMA and its Complex Interactions in the Brain

    MDMA, despite its potential therapeutic benefits, has addictive liability due to its amphetamine derivative properties. While it affects both the dopamine and serotonin systems in the brain, it has a higher affinity for and influences the serotonin system more. This can lead to a qualitative difference in the experience compared to other substances like cocaine or methamphetamine. Additionally, MDMA also has complex interactions with oxytocin, both upstream and downstream. The brain's complexity and intricacy necessitate deeper exploration and understanding. If MDMA is approved for certain therapeutic uses, it is important to be aware of its addictive potential.

    The Effects and Risks of MDMA/ Ecstasy

    MDMA, also known as ecstasy, has powerful effects on empathy and social interactions. It enhances the capacity for empathy and the experience of emotional states in others. These effects are believed to be mediated by its interactions with the serotonin system in the brain's reward circuitry. It is important to note that MDMA is a schedule one drug and illegal to possess or sell. Clinical trials are being conducted to explore its potential therapeutic uses. However, the use of MDMA outside of these settings can be dangerous due to the risk of fentanyl contamination and other unknown substances. It is crucial to prioritize safety and legality when considering MDMA use. Additionally, there are currently no FDA-approved drugs specifically targeting the social deficits associated with Autism Spectrum Disorder.

    Exploring the Potential of MDMA in Treating Autism Spectrum Disorder and Social Anxiety

    There is growing interest and ongoing research on the potential benefits of drugs like MDMA in treating individuals with Autism Spectrum Disorder (ASD) and social anxiety. Serotonergic systems, which utilize serotonin as a signaling molecule, are believed to play a role in social interactions in both mice and humans. The organization Maps, as well as other companies like MeMed, are actively studying the effects of MDMA on individuals with social anxiety and high functioning ASD. The different forms of MDMA, R MDMA and s MDMA, interact with the dopamine and serotonin systems differently, with s MDMA potentially having a higher interaction with the dopamine system. This research offers hope for finding new treatment options for individuals with sociability deficits and could potentially enhance our understanding of brain function and empathy.

    The Therapeutic Potential of Psychedelics and MDMA for Mental Health Challenges

    There is significant potential in exploring the therapeutic use of psychedelics and MDMA for mental health challenges. While drugs like LSD and psilocybin have been traditionally used as hallucinogens, MDMA offers a qualitatively different experience as an empathogen and actoxygen. These substances work through different receptor systems in the brain, creating distinct subjective effects. However, it is crucial to approach their use with caution and conduct rigorous, ethical scientific research. It is not a one-size-fits-all solution or a miracle cure. There is a need to study these substances in a scientific and rigorous manner to understand their mechanisms of action and unlock their therapeutic potential. Access to these substances should be carefully regulated to prevent negative experiences or misuse.

    Balancing Potential Benefits and Concerns: The Use of Psychedelic Substances in Clinical Trials

    There is both excitement and caution surrounding the use of psychedelic substances in clinical trials. While individuals like Robert Malenka acknowledge the potential benefits of these substances in treating mental illnesses and addiction, they also express concern about the need for careful, ethical, and controlled studies. They emphasize the importance of inclusionary and exclusionary criteria to ensure the safety and effectiveness of these substances. The conversation highlights the potential impact of negative experiences and outcomes on the progress of research and the reputation of psychedelic therapy.

    Asi Wind: What Magic & Mind Reading Reveal About the Brain

    Asi Wind: What Magic & Mind Reading Reveal About the Brain
    In this episode, my guest is Asi Wind. He's one of the world’s top magicians and mentalists.  We discuss what magic and mentalism reveal about the human mind, including how memories are made, how to erase them, and how and why we perceive things the way we do, all in the context of how he performs his astonishing tricks.  Asi explains that magic works because it involves storytelling, which is key to how we organize memories. He also explains how emotional connection allows people to co-create and believe a common narrative, even one that did not actually occur.  We also discuss how Asi's love of painting and photography and his specific daily routine allow him to access creativity. We also discuss fear, perfectionism, and how feeling emotions deeply serves his craft.  Whether you are interested in magic or not, this conversation with Asi will give you an incredible window into how you perceive, learn, and remember the world around you and how what you believe may or may not be based in reality.  For show notes, including referenced articles and additional resources, please visit hubermanlab.com.

    Dr. E.J. Chichilnisky: How the Brain Works, Curing Blindness & How to Navigate a Career Path
    In this episode, my guest is Dr. E.J. Chichilnisky, Ph.D., a professor of neurosurgery and ophthalmology at Stanford University. He studies how we see and uses that information to build artificial eyes that restore vision to the blind.  We discuss how understanding the retina (the light-sensing brain tissue that lines the back of our eyes) is critical to knowing how our brain works more generally.  We discuss brain augmentation with biologically informed prostheses, robotics, and AI and what this means for medicine and humanity.  We also discuss E.J.’s unique journey into neuroscience and how changing fields multiple times, combined with some wandering, taught him how to guide his decision-making in all realms of life.  This episode ought to be of interest to anyone interested in learning how the brain works from a world-class neuroscientist, those interested in the future of brain therapeutics and people seeking inspiration and tools for navigating their own professional and life journey.
