From Our Neurons to Yours

In this special crossover episode, we’re doing something a little different. From Our Neurons to Yours host Nicholas joins producer Michael Osborne to co-host his podcast Famous and Gravy [https://famousandgravy.com/] for a lively conversation about the extraordinary life and mind of Stephen Hawking. Hawking, one of the most renowned scientists of our time, lived with ALS for more than 50 years—defying medical expectations while also reshaping how we understand black holes, the universe, and our place within it. While Hawking wasn’t a neuroscientist, his neurological condition and his remarkable communication of complex ideas make his story especially relevant to From Our Neurons to Yours. In this episode, we explore: * How Hawking’s life with ALS shaped his outlook and scientific drive * His talent for making theoretical physics accessible (and entertaining) * Big philosophical questions about the universe and the nature of existence * The intersection of science, celebrity, and personal legacy We hope you enjoy this crossover conversation.

If addiction is a disease of the brain, what does that mean for how we treat people—and how we write policy? In this wide-ranging conversation, Stanford addiction expert and policy advisor Keith Humphreys returns to the show to walk us through what neuroscience has taught us about substance use disorders and how that science intersects with law, public health, and politics. From the biology of craving to the limits of autonomy, we explore the tension between compassion and accountability, and what truly effective treatment and prevention might look like. Episode Highlights * Why addiction isn’t just a moral failure—and how brain science explains drug-seeking behavior * The biological pathways affected by opioids, alcohol, and stimulants—and why some drugs are harder to treat * What makes some people more vulnerable to addiction than others * Why effective addiction policy must account for impaired decision-making * How policy can—and can’t—respond to the science * The promise and limitations of brain stimulation, psychedelics, and medications like naloxone * Why prevention—especially for teens—is key to long-term change * What a more human, effective, and science-based future could look like Resources & Links * Learn more about Keith Humphreys [https://profiles.stanford.edu/keith-humphreys] * Learn about the Stanford Network on Addiction Policy [https://med.stanford.edu/snap.html] * Read about the NeuroChoice Initiative [https://neuroscience.stanford.edu/news/neurochoice-eight-years-forging-connections-illuminate-and-empower-choice] at Stanford's Wu Tsai Neurosciences Institute * NIH resources on addiction science and treatment [https://nida.nih.gov/] * Read Humphreys' 2024 report on "The rise and fall of Pacific Northwest drug policy reform, 2020–2024" [https://www.brookings.edu/articles/the-rise-and-fall-of-pacific-northwest-drug-policy-reform-2020-2024/] (Brookings Institution, 2024) * Read about CARE Courts [https://www.nytimes.com/2024/03/21/us/california-care-court-mental-illness-homeless.html] ( "New California Court for the Mentally Ill Tests a State’s Liberal Values", New York Times, 2024) * Read Humphreys' 2025 Op-Ed: "Does harm reduction still have a future in San Francisco?"

A generation ago, a big clot in the brain meant paralysis or worse. Today, doctors can diagnose clots on AI-enabled brain scans; provide life-saving, targeted medications; or snake a catheter from a patient’s groin into the brain to vacuum out the clot. If they intervene in time, they can watch speech and movement return before the sedatives wear off. How did that happen—and what’s still missing? In this episode of From Our Neurons to Yours, Stanford neuroscientist and neurocritical care specialist Marion Buckwalter, MD, PhD [https://neuroscience.stanford.edu/people/marion-s-buckwalter-md-phd] retraces the 70-year chain of curiosity-driven research—biochemistry, imaging, materials science, AI—behind today’s remarkable improvements in stroke care. She also warns what future breakthroughs are at stake if support for basic science stalls.

We've all heard stories about someone who went in for surgery and came out...different. A grandmother who struggled with names after hip replacement, or an uncle who seemed foggy for months following cardiac bypass. But why does this happen to some people while others bounce right back? This week, we explore this question with Dr. Martin Angst, a professor of anesthesiology at Stanford who's studying the biological factors that determine cognitive outcomes after surgery. With support from the Knight Initiative for Brain Resilience, Martin and his team are following hundreds of cardiac surgery patients, tracking everything from blood biomarkers to cognitive performance both before and after their procedures. Their findings are revealing fascinating insights about what makes some brains more resilient than others when faced with the significant stress of major surgery - insights that could help physicians better advise patients and potentially lead to interventions that enhance resilience.

Imagine being trapped in your own body, unable to move or communicate effectively. This may seem like a nightmare, but it is a reality for many people living with brain or spinal cord injuries. We're re-releasing one of our favorite episodes from the archives: our 2024 conversation with Jaimie Henderson, a Stanford neurosurgeon leading groundbreaking research in brain-machine interfaces. Henderson shares how multiple types of brain implants are currently being developed to treat neurological disorders and restore communication for those who have lost the ability to speak. We also discuss the legacy of the late Krishna Shenoy and his transformative work in this field.
