Mailbag Episode 5: The Memory Machine
In this episode, Dr. Juan Carlos Rey of Crowscupboard.com invites listeners into a meditation on memory - no longer a candle passed from mind to mind, but a circuitry of data and desire. Drawing on the sociologist Maurice Halbwachs (1877–1945), Dr. Rey examines how collective memory has migrated from the oral to the algorithmic, shaping what humanity remembers - and what it forgets. From the neural encoding of emotion to the digital contagion of belief, this conversation explores why misinformation feels so persuasive: because the brain itself prizes coherence over accuracy. Memory is not a library - it is a living organism seeking equilibrium. Online, that organism meets the algorithm, and together they compose the myths of the present. Blending neuroscience, cultural theory, and reflective poetics, The Memory Machine asks: what happens when remembering becomes automated? And can we reclaim attention - the last uncommodified act of consciousness - as a form of moral resistance?

Interlude XVIII - Circadian Consciousness: How the Body Tells Time
In this episode of The Observable Unknown, Dr. Juan Carlos Rey of CrowsCupboard.com uncovers the hidden clockwork of the living body - the molecular rhythms that measure dawn, dusk, and everything between. Drawing on the Nobel-winning research of Jeffrey C. Hall, Michael Rosbash, and Michael W. Young, whose fruit-fly experiments at Brandeis University and Rockefeller University revealed the PER gene and its feedback loop, Dr. Rey shows how each of us carries an internal timepiece.From the suprachiasmatic nucleus in the brain to the clocks in our livers and immune cells, our biology lives in sync - or out of sync - with the cycles of Earth. Misalignment doesn’t just bring tiredness - it rewires mood, metabolism, and meaning.Whether you rise with the sun or scroll into the night, this show reveals that time is not simply measured - it is embodied.Please rate, review, and share your reflections wherever you’re listening.Visit CrowsCupboard.com to learn more about upcoming classes and connect with Dr. Rey directly by writing to TheObservableUnknown@gmail.com

Interlude XVII - Endogenous Opioids & The Biochemistry of Meaning
Before temples were built of stone, the body already knew how to worship.In this episode, Dr. Juan Carlos Rey of CrowsCupboard.com explores how the brain’s own narcotic chemistry - endorphins, enkephalins, and dynorphins - shapes the experience of love, faith, music, and transcendence. Drawing on the work of Candace Pert (1973), who first identified the brain’s opiate receptors, Jaak Panksepp (1998), who revealed the primal circuits of care and play, and Björn Lindström (2015), whose studies of synchronized movement uncovered the opioid basis of social bonding, Dr. Rey guides listeners through a physiological theology of awe.Every drumbeat, every chant, every shared breath becomes evidence that the sacred is written in chemistry. From early laboratory discoveries to modern neuroimaging of musical ecstasy, The Observable Unknown traces how meaning itself may be the body’s oldest high - how ritual, rhythm, and relationship activate an interior pharmacy of connection. The conversation extends into psychiatry and philosophy: what happens when trauma dulls these receptors, when faith becomes analgesic, or when hope itself behaves like a biochemical placebo? Listeners will leave understanding that spirituality is not opposed to science - it is embodied by it. The neurons that ache, the hormones that heal, the molecules that bind us together are the same forces that generate compassion and purpose.

Interlude XVI – Neural Oscillations and the Biochemistry of Rhythm
Before language, before heartbeat, there was rhythm - the pulse that shaped both cosmos and consciousness. In this episode of The Observable Unknown, Dr. Juan Carlos Rey of crowscupboard.com explores the hidden architecture of the mind’s music: the neural oscillations and neurochemical cadences that give rise to awareness itself. Drawing on research by György Buzsáki (New York University), Earl Miller (MIT), Christof Koch (Allen Institute for Brain Science), Laura Colgin (University of Texas at Austin), and Patricia Locke (UCLA), Dr. Rey examines how gamma, theta, alpha, and delta waves synchronize the brain’s electrical ensembles with the biochemistry of gamma-aminobutyric acid, glutamate, and acetylcholine. Through this rhythmic interplay, thought becomes chord, perception becomes phrase, and emotion becomes harmony. From Miller’s discovery that working memory depends on oscillatory phase-locking, to Colgin’s finding that hippocampal rhythms toggle between recalling the past and composing the future, we begin to see cognition as a living composition - part science, part symphony. Listeners are invited to consider a provocative question: what if consciousness is not computation but composition? When neurons resonate in phase, awareness coheres; when coherence breaks, selfhood dissolves into silence. Neural Oscillations and the Biochemistry of Rhythm reveals the mind not as machinery but as music - an improvisation between ions and intention. Follow Dr. Juan Carlos Rey on LinkedIn and X (@DrJuanCarlorRey), or share reflections at TheObservableUnknown@gmail.com.If the rhythm speaks to you, please leave a review or rating wherever you listen - it helps this inquiry into the measurable and the mystical reach new ears.

Mailbag Episode - “Sharpening the Sixth Sense: The Science and Soul of Intuition”
A listener writes from Toronto: “I’ve always felt intuitive - but I don’t know how to trust or strengthen it. Is intuition a gift or a skill?” In this episode of The Observable Unknown, I respond with both rigour and heart. Drawing on over two decades of research and training - from neuroscience to somatic practice to symbolic language - I share the system I’ve developed to help intuition become usable intelligence. We explore how the body-brain interface holds predictive power, how the nervous system speaks metaphorically, and how intuition can be taught, measured, and integrated into daily life. The sacred becomes trainable. The incipient awareness becomes architecture. If you’ve ever felt a signal you couldn’t translate, or a hunch you couldn’t trust, this episode invites you to step into the practice of knowing what you already feel.

Mailbag Episode 3: Eros and the Sacred Body
In this profound installment of The Observable Unknown, Dr. Juan Carlos Rey explores the ancient and often misunderstood intersection of erotic performance and spirituality. Responding to a listener’s question from San Antonio, Dr. Rey traces how the language of desire has always mirrored the language of the divine. From Plato’s Symposium to modern neuroscience, Eros emerges not as indulgence but as a way of knowing. Drawing on the work of Jaak Panksepp, Helen Fisher, and Andrew Newberg, Dr. Rey reveals that the same neural circuits governing erotic arousal - dopamine, oxytocin, and the reward pathways of the limbic system - also ignite during prayer, meditation, and states of awe. Pleasure and transcendence, he suggests, are biologically intertwined. This episode also examines performance as ritual: how the body, in conscious movement, becomes both subject and sacrament. We visit the anthropology of Dionysian rites, the psychological insights of Carl Jung, and the somatic therapies of Bessel van der Kolk and Peter Levine, each pointing toward a single truth - that awareness within desire transforms instinct into revelation. Listeners will discover that sacred sensuality is neither paradox nor provocation, but a form of embodied theology. In Dr. Rey’s words, “To feel is to know, and to know through feeling is to remember what the soul once forgot.” Tune in to The Observable Unknown for this meditation on the chemistry of longing, the neurobiology of transcendence, and the oldest sacrament of all - the consciousness that trembles when it recognizes itself.

Mailbag Episode 2 – “The Comparator and the Calling”
What if faith were simply the nervous system daring to trust its own prediction? In this Mailbag installment, Dr. Rey responds to listener DeShawn Carter of Atlanta, Georgia, whose question probes the hidden alliance between free will, intuition, and the brain’s comparator model – that quiet circuit which measures intention against outcome, authorship against experience. From Chris Frith’s neuroscience of agency to the ancient mystic’s surrender, this episode explores how faith and intuition emerge not in opposition to science but as its most mysterious expressions. Can belief be mapped onto synapses? Can intuition be a biological form of grace?Listen as Dr. Rey unravels these questions, reminding us that to know and to trust are not separate verbs but different tenses of the same awakening.

Interlude XV – Inheritance in Motion: Phylogenetic Inertia, Epigenetic Writing, and the Future of Human Becoming
What if evolution is not a finished act, but an ongoing collaboration between ancestry and awareness? In this interlude of The Observable Unknown, Dr. Juan Carlos Rey explores the profound intersection between phylogenetic inertia - the evolutionary gravity that preserves our biological past - and epigenetic rewriting, the molecular poetry of adaptation that lets life edit its own script. Through studies by Dr. Samuel Almeida, Dr. Michael Kertes, Dr. Jessica Loke, Dr. Steve Horvath, and Dr. Helena Verdile, this episode reveals how inheritance moves beyond genes: into chemistry, emotion, opportunity, and choice. From prenatal stress shaping neural architecture to trauma accelerating biological age, Interlude XV examines how the genome is less a fixed code and more a living text - revised through experience, reflection, and resilience. The question at its center is timeless:If life remembers itself through us, what might we, in turn, choose to remember for it?   Email: TheObservableUnknown@gmail.comText line: 336-675-5836 Please rate this episode and leave a review wherever you listen.

Interlude XIV - Epigenetic Neuroplasticity: Life Writing the Brain
What if memory is not only electrical - but molecular? In this new interlude, Dr. Juan Carlos Rey explores how experience, stress, and nurture inscribe themselves directly into the genome of the brain. Through the pioneering studies of Michael Meaney and Moshe Szyf, we learn that the nervous system is not a fixed circuit but a living manuscript - continuously edited by love, fear, and time. From the first experiments at McGill University in the early 2000s that revealed maternal care could alter gene methylation in the hippocampus, to the recent findings that environmental enrichment can rewrite those very marks, this episode unveils a profound idea:that the brain is not only remembering life - it is being written by it. Join Dr. Rey in exploring how trauma leaves biochemical footprints, how healing may be an act of epigenetic revision, and how consciousness itself may be a story the genome keeps telling anew.

Interlude XIII — Neuroimmunology: When the Brain Meets Immunity
What if emotion were an immune response?What if the dialogue between inflammation and thought shaped not only how we heal—but how we hope? In this interlude, Dr. Juan Carlos Rey explores the emerging science of neuroimmunology, where the immune and nervous systems reveal themselves as co-authors of consciousness.Through the work of Ronald Duman (Yale University), Harry Male (University of Illinois), and Jonathan Kipnis (Washington University in St. Louis), we trace how cytokines, microglia, and lymphatic pathways sculpt mood, memory, and meaning. From autoimmune melancholy to the “sickness behavior” that demands rest, this episode unveils the silent director behind cognition itself—showing that inflammation and illumination may be closer kin than we ever imagined.

Interlude X: Hormones, Hierarchy, and the Architecture of Desire
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.

Dr. Shireen Fatemi
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.
