Huberman Lab

In this episode, my guest is Mary Helen Immordino-Yang, EdD, professor of education, psychology and neuroscience at the University of Southern California and director of the Center for Affective Neuroscience, Development, Learning and Education, who has done groundbreaking research on emotions, self-awareness and social interactions and how these impact the way we learn and change across our lifespan. She explains how an understanding of emotions can be leveraged to improve learning in children and in adults, and how the education system should be altered to include new forms of exploration and to facilitate better learning and to include more diverse learning (and teaching) styles. This episode ought to be of interest to anyone interested in how we learn, human development in children and adults, as well as those generally interested in education, psychology or neuroscience.

Welcome to a preview of the seventh Ask Me Anything (AMA) episode, part of the Huberman Lab Premium subscription.

The Huberman Lab Premium subscription was launched for two main reasons. First, it was launched in order to raise support for the standard Huberman Lab podcast channel — which will continue to come out every Monday at zero-cost. Second, it was launched as a means to raise funds for important scientific research. A significant portion of proceeds from the Huberman Lab Premium subscription will fund human research (not animal models) selected by Dr. Huberman, with a dollar-for-dollar match from the Tiny Foundation.

In this episode, I explain how medications such as Adderall, Ritalin, Vyvanse and other stimulants work to increase focus and treat attention-deficit/hyperactivity disorder (ADHD). I explain the brain circuits involved in focus and the key roles dopamine and norepinephrine play in their regulation. Then I explain how stimulants such as Adderall and Vyvanse can increase focus and reduce hyperactivity in kids or adults with ADHD, and how and why Ritalin and other medications (e.g., Modafinil, Guanfacine) may work better for some. I explain the long-term effects of ADHD medications on height, cardiovascular health, hormones, predisposition to addiction and psychosis, and whether these treatments can be used and then stopped. I also discuss the immense individual variation in dosage sensitivity for these medications and the negative side-effects that occur from recreational use. This episode ought to benefit anyone with ADHD, their parents, those on ADHD medications or anyone curious about how these medications work.

In this episode, my guest is Robin Carhart-Harris, PhD, distinguished professor of neurology and psychiatry at the University of California, San Francisco. He is one of leading researchers in the study of how psychedelics such as psilocybin, LSD and DMT can change the human brain and in doing so, be used to successfully treat various mental health challenges such as major depression, anorexia, obsessive-compulsive disorder (OCD) and addiction. He explains how psilocybin induces sustained changes in adaptive brain wiring and cognition. We discuss the key components of safe and effective psychedelic journeys, the role of hallucinations, the use of eye-masks to encourage people to “go internal,” and music, as well as what effective therapist support consists of before, during and after the session (also known as integration). We discuss micodosing vs. macrodosing and how researchers control for placebo effects in psychedelic research. We also discuss the current legal landscape around psychedelic therapies. Psychedelic therapies are fast emerging as powerful and soon-to-be mainstream treatments for medical health disorders, but they are not without their risks. As such, this episode ought to be of use to anyone interested in brain plasticity, mental health, psychology or neuroscience.

In this episode, my guest is Susanna Søberg, PhD. She earned her doctoral degree at the University of Copenhagen in Denmark, researching the effects of deliberate cold and deliberate heat exposure on metabolism and other aspects of human physiology. We discuss how cold or sauna can improve metabolism, cardiovascular and brain health, balance hormones, and decrease inflammation. Dr. Søberg discusses how deliberate cold protocols can improve glucose metabolism and insulin sensitivity and trigger release of neurotransmitters like dopamine and norepinephrine which enhance energy, mood, and focus. We compare cold showers and cold immersion, traditional and infrared saunas, and other variables. This episode provides actionable tools and answers to common questions about the use of deliberate cold and heat to improve health.

In this episode, I discuss what psilocybin is (chemically) and how it works at the cellular and neural circuit level to trigger neuroplasticity, which is our brain’s ability to rewire itself in ways that lead to long-lasting shifts in our emotional, cognitive and behavioral patterns and abilities. I discuss the emerging clinical trial evidence for the use of psilocybin in the treatment of depression, addictions and other psychiatric challenges. I explain the typical duration and phases of a psilocybin journey, the different categories of dosages often used and I explain the importance of set, setting and support when using psychedelics. I explain which groups of people place themselves at great risk by taking psilocybin as well as groups that could benefit, and I highlight the rapidly changing legal and medical landscape around psilocybin. This episode is a thorough exploration of psilocybin from the scientific and clinical literature perspective and ought to be of interest to anyone curious about psilocybin, mental health, neuroplasticity and/or psychedelics more generally.

In this episode, my guest is Noam Sobel, PhD, professor of neurobiology in the department of brain sciences at the Weizmann Institute of Science. Dr. Sobel explains his lab’s research on the biological mechanisms of smell (“olfaction”) and how sensing odorants and chemicals in our environment impacts human behavior, cognition, social connections, and hormones. He explains how smell is a crucial component of “social sensing” and how we use olfaction when meeting new people to determine things about their physiology and psychology, and he explains how this impacts friendships and romantic partners. He explains how smell influences emotions, hormone levels, memories and the relationship between breathing and autonomic homeostasis. He describes how smell-based screening tests can aid disease diagnosis and explains his lab’s work on digitization of smell — which may soon allow online communication to include “sending of odors” via the internet. Dr. Sobel’s work illustrates how sensitive human olfaction is and how it drives much of our biology and behavior.

In this episode, I explore the science of mental visualization and its application for learning motor and cognitive skills. I discuss neuroplasticity-based skill development and the roles of focus, sleep, movement restriction, and agitation. I then present five key principles of mental visualization to enhance learning speed, accuracy, and consistency. I also provide examples of specific protocols, including repetitions, rest periods, and session frequency, and how to adapt these methods for injuries or breaks from traditional training. Throughout, I reference the scientific studies supporting these concepts. This episode should allow anyone to learn or teach more effectively through the use of mental visualization and training.

In this episode, my guest is Matthew MacDougall, MD, the head neurosurgeon at Neuralink. Dr. MacDougall trained at the University of California, San Diego and Stanford University School of Medicine and is a world expert in brain stimulation, repair and augmentation. He explains Neuralink’s mission and projects to develop and use neural implant technologies and robotics to 1) restore normal movement to paralyzed patients and those with neurodegeneration-based movement disorders (e.g., Parkinson’s, Huntington’s Disease) and to repair malfunctions of deep brain circuitry (e.g., those involved in addiction). He also discusses Neuralink’s efforts to create novel brain-machine interfaces (BMI) that enhance human learning, cognition and communication as a means to accelerate human progress. Dr. MacDougall also explains other uses of bio-integrated machines in daily life; for instance, he implanted himself with a radio chip into his hand that allows him to open specific doors, collect and store data and communicate with machines and other objects in unique ways. Listeners will learn about brain health and function through the lens of neurosurgery, neurotechnology, clinical medicine and Neuralink’s bold and unique mission. Anyone interested in how the brain works and can be made to work better ought to derive value from this discussion.
