Essentials: Psychedelics for Treating Mental Disorders | Dr. Matthew Johnson

In this Huberman Lab Essentials episode, my guest is Dr. Matthew Johnson, PhD, a senior researcher for the Center of Excellence for Psilocybin Research and Treatment at Sheppard Pratt’s Institute for Advanced Diagnostics and Therapeutics. We explore the science and therapeutic potential of psychedelic medicine, including psilocybin, MDMA and LSD. We discuss how these substances can profoundly alter perception and self-identity, providing long-lasting relief from depression, addiction and trauma when used in controlled clinical settings. We also discuss microdosing and emerging research on psychedelics’ potential to support recovery from neurological injuries. Read the episode show notes at hubermanlab.com.

My guest is Dr. Chris McCurdy, PhD, FAAPS, professor of medicinal chemistry at the University of Florida and a world expert on the pharmacology of kratom and other plant-derived medicinal compounds. We discuss kratom’s wide-ranging effects, including its use for boosting energy, enhancing mood, managing pain and as a potential opioid substitute, while also explaining its critical safety concerns and addictive potential, especially for kratom-derived/isolate products. We also discuss plant-based compounds more generally for their potential benefits and risks. Dr. McCurdy offers a balanced perspective on kratom and other plant-based and naturally occurring medicinal compounds, highlighting and contrasting their promise for human health with potential serious risks.

In this Huberman Lab Essentials episode, I discuss both healthy eating and clinically recognized eating disorders, including anorexia, bulimia and binge eating disorder. I explain how brain circuits, hormones such as leptin and reward systems interact to regulate appetite, satiety and overall eating behaviors. I also discuss the serious health risks associated with anorexia, explain how disrupted eating habits contribute to its development and highlight evidence-based treatments for anorexia. Finally, I explore binge eating and bulimia, discussing the underlying causes and the pharmacological treatments commonly used to support recovery. Read the episode show notes at hubermanlab.com.

My guest is Dr. Marc Berman, PhD, a professor of psychology at the University of Chicago whose research explores how different physical environments—particularly nature and patterns found in nature—can positively impact our ability to focus, our cognitive performance and our mental and physical health. We discuss how our physical environment influences our attention, stress levels and brain and heart health. He explains how even brief periods in nature and exposure to natural images and sounds can restore and improve attentional capacity, reduce mental fatigue and help combat rumination and depression. Whether you live in a city, suburb or rural area, this episode offers simple science-backed strategies for incorporating nature and natural elements into your daily life to positively transform your cognitive ability and mental and physical health.

In this Huberman Lab Essentials episode my guest is Dr. Robert Sapolsky, PhD, a professor of biology, neurology and neurological sciences at Stanford University.   We discuss different types of stress and how our perception of stress as harmful or beneficial largely depends on context. He also explains how testosterone amplifies pre-existing behaviors and tendencies, and he highlights the crucial role of estrogen in supporting brain and body health. We also discuss daily cognitive practices for stress mitigation and how modern life, influenced by social media and complex social hierarchies, shapes our responses to stress.

In this Huberman Lab Essentials episode, my guest is Dr. Anna Lembke, MD, Chief of the Stanford Addiction Medicine Dual Diagnosis Clinic at Stanford University School of Medicine. We discuss how dopamine drives reward, motivation and addictive behaviors. Dr. Lembke explains the concept of the pleasure-pain balance of dopamine and how this cycle plays a key role in the development and persistence of addiction. We also discuss some of the challenges of addiction recovery, including withdrawal, relapses and the potential benefits of psychedelic-assisted therapy.

In this episode I explain how your vagus nerve—an extensive neural pathway linking your brain and body in both directions—powerfully regulates your mood, digestion, alertness and even certain food cravings, and I explain how you can activate certain vagus nerve pathways to improve your heart rate variability (HRV), a key marker of health and longevity. I also explain how to control vagal pathways to enhance your focus and alertness to improve learning and neuroplasticity. And I explain how your vagus nerve controls levels of serotonin in both your gut and brain, impacting your mood and emotional resilience and how to keep that pathway robust.

In this Huberman Lab Essentials episode, I explore the sensations of pain and pleasure, explaining how they are sensed in the body and interpreted by the brain as well as methods to control their intensity. I discuss both the hardwired mechanisms and subjective factors that shape an individual’s perception of pain and pleasure. I also explain why pain thresholds vary from person to person and discuss various treatments for pain management such as acupuncture and supplements. Finally, I explain the role of key neurochemicals like dopamine and serotonin in mediating our experience of pain and pleasure. Read the episode show notes at hubermanlab.com.
