  • Can brain science save addiction policy? | Keith Humphreys
    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 HighlightsWhy addiction isn’t just a moral failure—and how brain science explains drug-seeking behaviorThe biological pathways affected by opioids, alcohol, and stimulants—and why some drugs are harder to treatWhat makes some people more vulnerable to addiction than othersWhy effective addiction policy must account for impaired decision-makingHow policy can—and can’t—respond to the scienceThe promise and limitations of brain stimulation, psychedelics, and medications like naloxoneWhy prevention—especially for teens—is key to long-term changeWhat a more human, effective, and science-based future could look likeResources & LinksLearn more about Keith HumphreysLearn about the Stanford Network on Addiction PolicyRead about the NeuroChoice Initiative at Stanford's Wu Tsai Neurosciences InstituteNIH resources on addiction science and treatmentRead Humphreys' 2024 report on "The rise and fall of Pacific Northwest drug policy reform, 2020–2024" (Brookings Institution, 2024)Read about CARE Courts ( "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?"

  • How basic science transformed stroke care
    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 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.Learn MoreBuckwalter Lab siteHistory of Stroke Care:Tissue Plasminogen Activator for Acute Ischemic Stroke (NINDS) On the development of the first-gen clot-busting drug, tPA Optimizing endovascular therapy for ischemic stroke (NINDS) On the development of mechanical clot clearance using thrombectomy.Mechanical Thrombectomy for Large Ischemic Stroke (Neurology, 2023) A literature meta-analysis shows that thrombectomy improves stroke outcomes by 2.5X, on top of 2X improvements from clot-busting drugsThe uncertain future of federal support for scienceThe Gutting of America’s Medical Research: Here Is Every Canceled or Delayed N.I.H.

  • Surgery as a window into brain resilience | Martin Angst
    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.Read MoreUnder the Lights: What Surgery Reveals About Brain Resilience (Knight Initiative for Brain Resilience, 2025)Infusion of young donor plasma components in older patients modifies the immune and inflammatory response to surgical tissue injury: a randomized clinical trial (Journal of Translational Medicine, 2025)Blood test predicts recovery after hip-replacement surgery, study finds (Stanford Medicine, 2021)Can major surgery increase risk for Alzheimer's disease?

  • Best of: How neural prosthetics could free minds trapped by brain injury | Jaimie Henderson
    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.Learn moreHenderson's Neural Prosthetics Translational LabBrainGate Consortium – "Turning thought into action"‘Unprecedented’ level of control allows person without use of limbs to operate virtual quadcopter (University of Michigan, 2025)Brain Implants Helped 5 People Recover From Traumatic Injuries (New York Times, 2023)The man who controls computers with his mind (New York Times Magazine, 2022)Software turns ‘mental handwriting’ into on-screen words, sentences (Stanford Medicine, 2021)Related video: Wu Tsai Neurosciences Institute, 2021Related publication: Nature, 2021Learn about the work of the late Krishna ShenoyKrishna V.

  • The secrets of resilient aging | Beth Mormino & Anthony Wagner
    This week on the show, we're have our sights set on healthy aging. What would it mean to be able to live to 80, 90 or 100 with our cognitive abilities intact and able to maintain an independent lifestyle right to the end of our days? We're joined by Beth Mormino and Anthony Wagner who lead the Stanford Aging and Memory Study, which recruits cognitively healthy older adults to understand what makes their brains particularly resilient — and how more of us could join them in living the dream of healthy aging.Learn MoreStanford Aging and Memory Study (SAMS)Stanford Memory LabMormino LabFurther ReadingAlzheimer's 'resilience signature' predicts who will develop dementia—and how fast (Knight Initiative for Brain Resilience, 2025)Latest Alzheimer's lab tests focus on memory loss, not brain plaques (NPR, 2025)ReferencesTrelle, A.
