How to Understand Emotions | Dr. Lisa Feldman Barrett

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. For the full show notes, visit hubermanlab.com.

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. For the full show notes, visit hubermanlab.com.

Welcome to a preview of the sixth 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 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. For the full show notes, visit hubermanlab.com.

In this episode, I explain the biology of hair, hair growth, why hair growth slows and what causes hair to stop growing and/or “fall out.” I discuss the essential role of hair stem cells and other supporting biological factors for healthy hair growth. Then I describe various approaches (mechanical and chemical) to slow hair loss by increasing blood flow to hair stem cells, including minoxidil, tadalafil, PRP, microneedling, Botox and ketoconazole treatments. I also discuss how age-related hormone changes cause hair loss and explain the effectiveness of treatments such as caffeine, saw palmetto, growth hormone, finasteride and dutasteride. For all hair growth options, I describe potential side effects, how soon to expect results and the amount of hair regrowth to expect and I highlight effective combination treatments for hair regrowth even in hair “dead” (bald) zones. For many listeners, thinning, brittle hair, or pattern baldness are a source of anxiety and stress. This episode explains the mechanisms underlying hair regrowth tools and the science behind them so that you can evaluate potential treatments and associated side-effect profiles and select the best one(s) for you.

In this episode, my guest is Elissa Epel, Ph.D., professor and vice chair of the department of psychiatry at the University of California San Francisco (UCSF) and the author of a new book entitled "The Stress Prescription." We discuss her work showing how stress impacts mood, eating behavior, mental health, physical health, and aging. She explains stress intervention tools using “top-down” techniques (e.g., radical acceptance, mindfulness, reframing), body-based methods (e.g., breathwork) including the Wim Hof Method, exercise, meditation, body scans, and environmental shifts proven to help people cease unhealthy rumination patterns. We discuss how stress can positively impact psychology and sense of purpose, how stress affects cellular aging, how our narratives of stressful events impact our mood and biology, and how to effectively reframe stress. She explains science-based techniques to break stress-induced cycles of craving and overeating and thereby improve insulin sensitivity and metabolic health. Dr. Epel provides a wide range of tools shown to be effective in reducing stress and improving various aspects of our health. For the full show notes, visit hubermanlab.com.
