Essentials: The Biology of Aggression, Mating & Arousal | Dr. David Anderson

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.

In this Huberman Lab Essentials episode, my guest is Dr. Andy Galpin, PhD, Executive Director of the Human Performance Center at Parker University and an expert in building strength and muscle size (hypertrophy). We cover the core principles and protocols for building strength and muscle, including science-based guidance on reps, sets, frequency and rest intervals. We also discuss how breathing and mental focus can enhance training and how post-workout downregulation can speed recovery. Read the show notes at hubermanlab.com.

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.
