Huberman Lab

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 [https://www.hubermanlab.com/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.

My guest is Michael Easter [https://eastermichael.com/], a professor at the University of Nevada, Las Vegas and best-selling author. We discuss how particular daily life choices undermine our level of joy, our sense of purpose, our physical and our mental health and the daily, weekly, monthly and yearly steps we can all take to vastly increase our level of motivation, gratitude and overall life satisfaction. We discuss how effortful foraging for information, undistracted reflection and physical exercise are ways to ‘invest’ and therefore grow our levels of dopamine, energy and motivation, whereas low-friction activities are specifically designed to hijack or diminish them. We also discuss dopamine reward circuitry in the context of how to build and reset one’s energy levels and create a deeper sense of purpose in work, creative pursuits and relationships.

My guest is Dr. Jay Bhattacharya, MD, PhD, Director of the National Institutes of Health (NIH) [https://www.nih.gov/news-events/news-releases/jay-bhattacharya-begins-tenure-18th-director-national-institutes-health] and Professor Emeritus of Health Policy at Stanford University [https://profiles.stanford.edu/jay-bhattacharya]. We discuss which scientific questions ought to be the priority for NIH, how to incentivize bold, innovative science especially from younger labs, how to solve the replication crisis and restore trust and transparency in science and public health, including acknowledging prior failures by the NIH. We discuss the COVID-19 pandemic and the data and sociological factors that motivated lockdowns, masking and vaccine mandates. Dr. Bhattacharya shares his views on how to resolve the vaccine–autism debate and how best to find the causes and cures for autism and chronic diseases. The topics we cover impact everyone: male, female, young and old and, given that NIH is the premier research and public health organization in the world, extend to Americans and non-Americans alike.
