In this episode, my guest is Dr. David Linden, Ph.D., professor of neuroscience at Johns Hopkins University School of Medicine and the author of many popular books about the brain. We discuss individual differences between people — focusing on differences in how people sense the world around them and the roles that chance, heredity, and life experiences (even in utero) play in determining our physical and cognitive traits. We discuss the bidirectional connection between the mind and body and how our thoughts and mental practices (e.g., meditation and breathwork) impact our health. We also discuss the link between inflammation and depression. We also discuss Dr. Linden’s terminal illness diagnosis, his mindset during chemotherapy and what his diagnosis has taught him about the mind, gratitude, time perception and life. This episode also covers sensual touch, cerebellar function, and epigenetic inheritance and ought to be of interest to all interested in neuroscience, genetics, psychology and human development.  For show notes, including referenced articles and additional resources, please visit hubermanlab.com.

In this episode, I explain how ketamine causes rewiring of brain circuits and dissociative states to relieve symptoms of depression and post-traumatic stress disorder (PTSD). I explain how ketamine impacts both the brain’s glutamate and its endogenous opioid pathways, which together regulate mood and well-being. I discuss how ketamine therapy is used clinically to treat major depression, bipolar depression, obsessive-compulsive disorder (OCD), suicidality and other psychiatric challenges. I also describe how ketamine causes the subjective effects of dissociation and euphoria and, at higher doses, is an anesthetic. I compare the different routes of ketamine administration, dosages and forms of ketamine, and if micro-dosing ketamine is effective. I also highlight the potential risks of recreational ketamine use (and the colloquial term ‘K-holes’). This episode should interest anyone interested in ketamine, treatments for depression, neuroplasticity mechanisms, psychiatry and mental health.

Welcome to a preview of the ninth 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 discuss how to build and apply a growth mindset — the practice of self-rewarding and focusing on learning and skill development through effort — to improve learning and performance. I also discuss how our internal narratives drive our ability to make progress. I contrast the growth mindset vs. the fixed mindset and describe how the type of feedback or praise we receive shapes our mindsets, and the huge advantage of rewarding and celebrating “verbs” (actions) rather than adjectives (performance labels). I also discuss data showing how stress can enhance performance and explain why the growth mindset works synergistically with the “stress-is-enhancing mindset,” and how to combine them. Whether you are a student, coach, therapist, parent, teacher or simply someone seeking to improve at something, this episode provides numerous science-supported tools for how to adopt a performance enhancing mindset.

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.
