  • #85 - The Power and Limits of Memory with Dr. Charan Ranganath
    2024/11/11

    Matt dives deep into the science of memory with renowned neuroscientist Dr. Charan Ranganath, author of Why We Remember: Unlocking Memory's Power to Hold On to What Matters in today’s episode. Together, they explore the complex relationship between memory and the brain, touching on the roles of emotional significance, context, and even neuromodulators like dopamine in helping our brains decide which memories to retain and which to discard.

    Dr. Ranganath shares his unique journey into memory research and insights from his pioneering work at the Dynamic Memory Lab at UC Davis, where his studies have reshaped our understanding of human memory. He also explains the diversity within memory types—such as episodic, semantic, and procedural memories—and why they’re all processed differently. Delving into extraordinary memory phenomena, he discusses hyperthymesia, false memories, and cases of severely deficient autobiographical memory, illustrating the varied ways people experience memory. This episode is a rich journey into the science and experience of memory, concluding with a refreshing reminder: sometimes, forgetting can be just as beneficial as remembering, offering us a balanced perspective on our memory's true role in daily life.

  • #84 - Sleep & Narcolepsy
    2024/10/28

    Matt returns this week to unpack the complexities of narcolepsy, a neurological sleep disorder often misunderstood and misdiagnosed. He starts by defining narcolepsy, explaining its profound impact on brain and body functioning and its chronic nature, which often diminishes patients' quality of life. Narcolepsy affects about 1 in every 2,000 people, yet most go undiagnosed due to limited awareness and medical training on sleep disorders. With a closer look at the causes, Matt explores how the brain's sleep-wake regulator, orexin, malfunctions in those with narcolepsy, disrupting their sleep cycles and resulting in excessive daytime sleepiness and sleep "attacks."

    Delving into symptoms, Matt highlights narcolepsy’s hallmark indicators, such as cataplexy—a sudden loss of muscle tone triggered by strong emotions—and frequent REM sleep disruptions that can lead to vivid hallucinations upon sleep onset. The episode covers diagnostic tools, from sleep studies to brain chemical tests, which help identify the condition. While there is currently no cure, Matt discusses various treatment options, from alertness-enhancing medications to emerging research and therapies. This episode calls for greater compassion and support for those with narcolepsy, emphasizing the importance of awareness and education in managing this life-altering disorder.

  • #83 - Sleeping Separate vs. Your Relationship
    2024/10/14

    Matt revisits the concept of "sleep divorce," or "sleep separation" in this latest episode, examining its effects on relationships and well-being. He cites studies showing that up to one in four couples in the U.S. and U.K. sleep in separate rooms, a statistic often underestimated due to stigma. While many fear that sleeping apart harms intimacy, Matt presents data indicating that it can actually enhance sleep quality and intimacy by promoting better-rested bodies and increasing hormones like testosterone and estrogen.

    He also discusses new research on the psychology of co-sleeping, revealing that despite poorer sleep quality, many couples feel more satisfied when sharing a bed, driven by a deep-rooted need for social connection, known as "somato longing." This episode encourages listeners to reflect on their own sleep habits and offers advice on discussing sleep separation with partners, emphasizing that the choice to sleep together or apart should prioritize open communication and individual health.

  • Ask Me Anything Part 11 - Falling Asleep, Staying Asleep, and False Awakenings
    2024/10/07

    Matt and Eti return today for another AMA session where they dive into even more fascinating and often quirky sleep questions that have been submitted by listeners. In this installment, our duo explores the evolutionary puzzle of why we sleep, despite the apparent risks it poses for survival. They also share insights into how early organisms, like earthworms, exhibit sleep-like states, which raises the question: did wakefulness evolve from sleep?

    As the episode continues, the pair tackle practical questions from listeners on how to fall asleep faster and stay asleep. Relaxation techniques like deep breathing, mindfulness, and avoiding clock-watching are highlighted as effective tools to combat sleep struggles. They also emphasize the importance of maintaining regular sleep schedules, avoiding heavy meals, and reducing caffeine intake. Matt goes on to suggest that minimizing noise pollution can make a big difference, and earplugs might be the solution for many. Eti notes that she swears by silicone ones, and, while she and Matt have no financial relationship to, or sponsorship from, the company, you can check out the earplugs Eti loves here.

  • #81 - Aging, Alzheimer’s, and Sleep with Dr. William Jagust
    2024/09/09

    Dr. William “Bill” Jagust, renowned expert in brain science and Alzheimer’s research - and one of the reasons Matt chose to move to UC Berkeley - joins our host today for an in-depth discussion on aging, cognitive decline, and the critical role of neuroimaging, with some sleep talk woven in as well. Dr. Jagust shares groundbreaking insights into how PET scans can detect amyloid and tau proteins in the brain—two key contributors to Alzheimer’s disease—years before symptoms emerge. Together with Matt he goes on to explore the connection between these proteins and brain aging, highlighting the power of biomarkers and advanced imaging in tracking the disease's progression. Our esteemed guest also emphasizes that early detection and intervention are crucial in slowing Alzheimer's progression, but warns that once neurons are damaged, the brain has minimal capacity to repair itself. He further discusses lifestyle choices such as exercise, diet, and sleep, which can lower the risk of cognitive decline, and dives into emerging research on genetic factors like the APOE4 gene. The episode concludes with a hopeful outlook on the future of Alzheimer’s research, offering insights into potential preventive treatments.
