Essentials: Science of Building Strong Social Bonds with Family, Friends & Romantic Partners
Andrew Huberman explains the biology and psychology of social bonding, covering neural circuits, neurochemicals, and hormones that govern how we form and maintain relationships. He describes social homeostasis circuits involving structures like the ACC, amygdala, hypothalamus, and dorsal raphe nucleus, and discusses how introversion and extroversion may relate to dopamine responses to social interaction. He also explores physiological synchrony, early caregiver-infant attachment, emotional versus cognitive empathy, the role of oxytocin, and what happens in the nervous system during breakups.
What Loneliness Does To Your Brain with Ben Rein
Neil deGrasse Tyson, Gary O'Reilly, and Chuck interview neuroscientist Ben Rein about what loneliness and social isolation do to the brain and body. They distinguish between objective isolation and the subjective feeling of loneliness, explain the stress and inflammatory pathways involved, and discuss how personality, aging, technology, and drugs like alcohol, painkillers, and MDMA affect social behavior and health. Rein also shares research on empathy, dogs and oxytocin, and practical ideas for rebuilding social connection in an increasingly automated world.
No. 1 Sugar Expert: 17 Seconds Of Pleasure Can Rewire Your Brain!
Dr. Robert Lustig explains how dopamine-driven behaviors and ultra-processed food, especially sugar, can create a "hostage brain" by rewiring reward pathways and degrading metabolic and brain health. He details mechanisms linking sugar, artificial sweeteners, mitochondrial dysfunction, and reactive oxygen species to Alzheimer's, cancer, depression, and other chronic diseases, while contrasting environmental versus genetic risk. The conversation also covers GLP-1 weight-loss drugs, vaccines and public health communication, loneliness, serotonin and oxytocin, practical strategies to reduce sugar and ultra-processed food, and emerging research on psychedelics and brain rewiring.
