What if intuition… digestion… and belief were all part of the same conversation?

In this interlude, Dr. Juan Carlos Rey explores the growing science of the gut-brain axis - where trillions of microbes whisper through the vagus nerve to shape emotion, cognition, and even moral intuition.

Drawing on research from Emeran Mayer, Sarkis Mazmanian, John Cryan, and Ted Dinan, this journey reveals a hidden ecology of consciousness - where neurotransmitters, bacteria, and the human nervous system collaborate to compose what we call self.

Here, the Observable Unknown is not distant or abstract - it’s inside you. Alive, responsive, and evolving.

What if every thought, memory, and feeling were a chemical symphony? In this interlude, Dr. Juan Carlos Rey guides listeners through the molecular foundations of consciousness—how neurotransmitters like acetylcholine, dopamine, serotonin, oxytocin, and cortisol shape our choices, memories, and moods.

Drawing on Michael Hasselmo’s groundbreaking work on acetylcholine and memory, Hans Krebs’ discovery of the metabolic “Krebs cycle” powering every thought, and the research of scholars such as Wolfram Schultz, Kent Berridge, Robert Sapolsky, Paul Zak, Bruce McEwen, Robin Carhart-Harris, Roland Griffiths, and Gregory Bateson, this episode uncovers the hidden chemistry of our inner life.

It’s a journey into the observable unknown where molecules meet mystery—where the self is revealed as a living metabolism of wonder.

What if your most “rational” decisions were already scripted by your bloodstream?

In this interlude of The Observable Unknown, Dr. Juan Carlos Rey traces the hidden hormonal currents shaping risk, loyalty, ambition, and status. Drawing on the fieldwork of Robert Sapolsky among Kenyan baboons, Anna Dreber’s research on traders’ testosterone surges, Carsten de Dreu’s discoveries about oxytocin’s double edge, Wolfram Schultz’s dopamine experiments, and anthropological studies from Kristen Hawkes to David Hazlerigg, this episode reveals how biology and culture braid into one force.

Testosterone asserts, cortisol constrains, oxytocin binds, dopamine drives - together forming the unseen scaffolding of our choices. By the end, you’ll never look at “free will” the same way again.

In this episode, I am joined by Dr. Shireen Fatemi, a distinguished endocrinologist whose vision of medicine extends far beyond lab values and prescriptions. Raised in a family that blended science with intuition, Dr. Fatemi brings a rare voice to the conversation about the body’s most mysterious messengers: our hormones.

Together, we explore how endocrinology illuminates not just physical health, but also mood, memory, and identity. From the impact of cortisol and circadian rhythm, to the cultural overreliance on medication, to the uncharted mysteries of the pineal gland, Dr. Fatemi challenges us to see the human being as both rational and hormonal - balanced, interwoven, and profoundly alive.

This is not just a medical conversation. It is a meditation on how hidden systems guide our choices, shape our stages of life, and even open questions of spirit and selfhood.

What happens when individuality dissolves into the crowd? From Durkheim’s collective effervescence to Tarde’s contagion of imitation, from Canetti’s swarm psychology to Girard’s scapegoat mechanism, and from Zimbardo’s situational power to Arendt’s banality of evil, this interlude explores the hidden dynamics of group mind.

The observable unknown here is the collective itself: a force that shapes choice, obedience, and even violence, while remaining invisible to those within it.

"What is history but a fable agreed upon?” Napoleon once asked. From collective recollection to sacred ritual, from covert interpersonal dramas to the unconscious resonance of color, from emotional imprints to memetic replication - this interlude explores the hidden architectures shaping what we call freedom.

Join Dr. Juan Carlos Rey as he traces Halbwachs, Eliade, Campbell, Berne, Damasio, Lüscher, and Blackmore, revealing how conviction is never solitary but always cultural, emotional, and inherited.

In this interlude, Dr. Juan Carlos Rey steps into the hidden architectures shaping what we call “free choice.” Drawing on Durkheim, Halbwachs, Berger, Bourdieu, Foucault, Elias, Geertz, Butler, Gramsci, and Meloni, he unpacks how collective memory, power, ritual, and even biology create the stage on which our decisions are performed.

Listeners are invited to explore the observable unknown of their own choices - what is inherited, what is suggested, and what may still be truly free.

Because freedom itself begins with seeing the pattern.
