    Dr. Elizabeth Margulis is a professor of music cognition at Princeton University and author of Transported: The Everyday Magic of Musical Daydreams.
    When strangers listen to the same unfamiliar music, they independently imagine the same vivid stories — down to specific words like "frolic" and "pirates." This may be one of the most surprising findings in modern cognitive science, and it challenges everything we assume about the privacy of our own thoughts.
    Expect to learn why strangers imagine the same stories when listening to identical music, how a cross-cultural experiment between the US and rural China revealed completely different imagined worlds to the same sounds, how repeated speech spontaneously transforms into song, the surprising link between psychedelic therapy and modern music therapy, why the Mozart Effect misled state legislatures, what makes certain songs irresistibly groovy, and much more

    Tim Maudlin is a philosopher of physics at NYU and founder of the John Bell Institute for the Foundations of Physics. In 1989 he published a paper proving that consciousness cannot arise from computation — thirty-five years before the world started panicking about whether ChatGPT can think.
    Expect to learn why no computer programme will ever be sufficient for consciousness, why large language models operate nothing like human brains, the critical difference between intelligence and consciousness that the AI industry keeps collapsing, why Penrose's arguments about consciousness are wrong, why quantum mechanics has nothing to do with the mind, why the mind-body problem may be the most intractable problem in all of science, and much more…

    #108 - Meet the Neuroscientist Who Discovered That Waves Produce Memory, Spacetime and Consciousness

    Dr. György Buzsáki is one of the world’s most influential neuroscientists and the author of The Brain from Inside Out — a radical rethinking of how the brain generates perception, memory, and consciousness.
    We’ve been asking the wrong questions about the mind. Memory isn’t storage. Perception isn’t passive. Time and space aren’t sensed — they’re constructed. And the rhythms of our own bodies may be the hidden scaffolding behind everything we think, feel, and remember.
    Expect to learn why the brain doesn’t record the world but predicts it, how neural rhythms act like syntax to structure our thoughts, why time is not an input but a product of the brain’s internal cycles, how space and memory emerge from the same temporal code, why consciousness might just be a performance built from nested oscillations, what happens when brain–body rhythms fall out of sync, how we can think about memory as musical replay not archival storage, how rhythm breakdown may underlie mental disorders, and much more

    #107 Dr Wendy Suzuki: How The Hippocampus Weaves Your Memories Into Consciousness

    Dr Wendy Suzuki is a Neuroscientist and Professor at New York University whose lab was the first to capture neurons firing as new memories are born. Her TED talk has over 65 million views, and she's the author of Good Anxiety and Healthy Brain, Happy Life.
    The hippocampus isn't just where memories are stored — it's the structure that builds your internal model of reality, imagines futures you've never lived, and may be the engine that constructs your sense of self.
    Expect to learn how place cells and grid cells map your world inside your skull, why people without a hippocampus can't imagine a tropical beach, how memories become models and models become selves, what the default mode network reveals about consciousness, how exercise physically grows new brain cells even into your 90s, why the boundary between memory and imagination is far blurrier than you think, and much more…

    #106 - Meet The Greatest Living Psychedelic Scientist You've Never Heard Of

    Dr. David E. Nichols is a pharmacologist, medicinal chemist, and widely regarded as the greatest living psychedelic scientist. He personally synthesized the psilocybin, MDMA, and DMT used in the most landmark psychedelic studies ever conducted — and founded the institute that funded most of them. He is 81 years old, has published nearly 300 scientific papers, and there is no one alive who can replace him.
    Expect to learn how he made a kilogram of MDMA for $4,000 and changed the course of psychiatry, what his first LSD trip revealed about the function of the universe, why psilocybin may be the most effective depression treatment we have, how his research was stolen and turned into street drugs that killed people, why the DMT pineal gland theory is scientifically impossible, whether consciousness lives in the brain at all, and much more…
