In this Huberman Lab Essentials episode, my guest is Dr. Erich Jarvis, PhD, a professor and Head of the Laboratory of Neurogenetics of Language at Rockefeller University and an investigator at the Howard Hughes Medical Institute (HHMI). We discuss the brain circuits and genes underlying spoken language and why the ability to learn and produce vocalizations is extraordinarily rare in the animal kingdom. We also explore why song likely evolved before language, how gesture and movement share deep neural roots with speech, the neurobiology of stuttering, why childhood is the optimal window for language acquisition, and how physical movement — including dance — may help preserve speech and cognitive function across a lifetime.

Dr. Marc Brackett, PhD, is founding director of the Yale Center for Emotional Intelligence and a professor in the Child Study Center at Yale University. We discuss the science of emotion regulation and practical tools to increase your emotional intelligence. Dr. Brackett clarifies exactly how to do that both in the context of relationships, but also things that you can do on your own to become more emotionally intelligent to later serve you in the context of relationships, work, school, etc. We also discuss how your childhood experiences influence your relationship with emotions, with particular emphasis on how boys and men are socialized around emotional processing and expression.

In this Huberman Lab Essentials episode, I explain how memories are formed and how key neurochemicals, such as adrenaline, can be leveraged to enhance memory formation. I also share science-based protocols to enhance learning, strengthen memory recall and reduce the number of repetitions needed to retain new information. In addition, I discuss how exercise supports cognitive function and memory and explore unique memory phenomena such as déjà vu. Read the show notes at hubermanlab.com.

Dr. Natalie Crawford, MD, is a double board-certified OB-GYN and reproductive endocrinologist. We discuss how to improve hormone health at any age and the importance of fertility markers not just for pregnancy, but as a powerful window into overall health, vitality and longevity. We discuss hormone replacement therapy, egg freezing, IVF, and what biomarkers like AMH really indicate. Plus, how anti-inflammatory diets and specific supplements can be beneficial and the impact of microplastics and certain fragrances on hormones. We also discuss lesser-known factors that deplete male and female fertility, vitality and health. This conversation highlights how better understanding of hormones and your reproductive markers can empower better informed choices at every stage of life. Read the show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, my guest is Dr. David Anderson, PhD, a professor of biology at the California Institute of Technology (Caltech) and an investigator at the Howard Hughes Medical Institute (HHMI). We discuss the brain circuits that underlie how emotions emerge and shape behaviors, including the neural control of fear, aggression and pain. We also explore how hormones and neuromodulators influence these emotional states, and why understanding these hidden internal processes is essential for improving future mental health treatments.

Dr. Dacher Keltner, PhD, is a professor of psychology at the University of California, Berkeley, and a leading expert on the science of emotions and human connection. We discuss the science of awe—what evokes it and how to access it. Dr. Keltner explains how awe helps us frame our experience of life and who we are both as individuals and collectively. We also discuss the role of humor in social bonding, dispel common myths about the biology of emotions and review the lesser-known factors that strengthen or inhibit relationships and communities.

Dr. Marc Breedlove, PhD, is a professor of neuroscience at Michigan State University and an expert on how hormones shape brain development and sexual orientation. We discuss how prenatal testosterone impacts whether someone is romantically attracted to men or women later in life, and what correlates of sexual orientation — such as finger-length ratios — tell us about the role of hormones in brain and psychological development. We also discuss why the number of older brothers a male has biases sexual orientation. Throughout, we explain how nature and nurture interact to shape male-female differences, behavior, and romantic partner choice.

In this Huberman Lab Essentials episode, I explain how salt (sodium) affects mental and physical performance, as well as cellular health. I describe how the brain monitors sodium levels to regulate thirst and fluid balance, and why salt needs can vary depending on activity level, stress, blood pressure, and diet. I also explain how to determine the right sodium intake for your individual needs and discuss why some people may benefit from increasing salt and other electrolytes.

In this Huberman Lab Essentials episode, I discuss the mechanisms through which deliberate heat exposure enhances both physical and mental health. I outline specific protocols for deliberate heat exposure, including recommended temperature ranges, frequency, timing, duration and sauna alternatives. In addition, I explain how to tailor your heat protocols to support your specific goals, such as increasing growth hormone, reducing cortisol or supporting cognitive health.

Dr. Alex Marson, MD, PhD, is a Senior Investigator at the Gladstone Institutes and a professor of medicine at the University of California, San Francisco. We discuss the biology of the immune system and cancer, and everyday choices that can increase or decrease your cancer risk, several of which are surprising but all of which are actionable. We also discuss immunotherapy, including how engineered T-cells can be used to defeat childhood and adult cancers. Dr. Marson explains CRISPR and gene editing to cure diseases, and we address the ethical questions surrounding gene editing in embryos, children and adults. This discussion is for anyone interested in avoiding cancer and/or seeking to understand the science and practical applications of immune- or gene-therapy. Read the show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, my guest is Dr. Charles Zuker, PhD, a professor of biochemistry, molecular biophysics and neuroscience at Columbia University and an Investigator with the Howard Hughes Medical Institute (HHMI). We explore taste perception and how the brain transforms chemical signals from food into distinct taste experiences. We discuss how these taste signals shape both conscious choices and unconscious behavior, as well as how food preferences can change over time. Additionally, we discuss gut–brain signaling and explain why sugar is especially powerful at driving cravings. Read the episode show notes at hubermanlab.com.
