Dr. Alfredo Spagna is a Cognitive Neuroscientist at Columbia University who discovered the Fusiform Imagery Node — the brain region that activates every time you imagine anything. But when he scanned people with aphantasia using an ultra-high-field 7T brain scanner, the node was firing perfectly — it just wasn't connected to the frontal lobe, suggesting that consciousness itself might depend not on what your brain computes, but on what it connects.Expect to learn how imagination hijacks the brain's perceptual system, why aphantasia shattered 40 years of assumptions about mental imagery, what the "visualizer fallacy" is and why it affects everything from therapy to education, how a painter with aphantasia creates art without ever seeing it in his mind, why your brain imagining a lemon makes you salivate even though there's no lemon, what the 7T brain scanner revealed about the architecture of imagination, how aphantasia may support the Global Neuronal Workspace theory of consciousness, why Olympic athletes spend hours visualizing routines they never physically perform, and much more…Timestamps00:08 What Happens in the Brain When You Imagine01:02 Where Imagination and Perception Diverge03:44 Would Perfect Imagination Be Hallucination?05:49 Voluntary vs Involuntary Imagination06:50 Why Do People with Aphantasia Still Dream?07:33 What Is Aphantasia — The Discovery That Changed Everything09:30 The Dissociation That Frightened Scientists11:06 The Visualizer Fallacy12:01 How Aphantasics Solve Problems Without Images14:31 Evan's Sister Discovers Aphantasia at 3116:55 Could Imagery Be Unconscious in Aphantasia?18:19 The Architect Who Lost His Imagination21:11 Eric the Painter — Creating Art Without Seeing It24:51 The Inner Speech Fallacy and Neurodiversity29:02 "I Can't Visualize My Mom's Face"29:57 Why Aphantasia Breaks Psychotherapy33:06 Empathy, Conflict and How Inner Experience Shapes Society36:42 The Chemistry Exam Problem39:09 Is Hypervisualization Actually a Disadvantage?41:21 Imagination as a Double-Edged Sword43:37 What Is the Fusiform Imagery Node?46:10 The Cafeteria Conversation That Started It All50:07 Three Bombshells From One Meta-Analysis52:23 Domain-General vs Domain-Specific Imagination54:05 The Brain Still Imagines in Aphantasia — It Just Disconnects56:36 Is Aphantasia a Disconnection Syndrome?58:59 Step-By-Step: What Your Brain Does When You Imagine an Apple1:05:05 Non-Visual Imagination — Taste, Touch, Sound1:09:38 What Aphantasia Reveals About Consciousness1:13:26 Does This Support IIT or Global Workspace Theory?1:15:49 Can Aphantasia Be Trained Away?1:18:53 The Olympic Skier Who Visualized Gold1:22:25 $10 Billion to Solve Imagination — Where Would You Spend It?...Email for sponsorship enquiries: evan@thegiantsshoulder.com ❤️ Subscribe to our main channel - https://www.youtube.com/@thegiantsshoulder?sub_confirmation=1💚 Follow on Spotify - https://open.spotify.com/show/5m3Gta5MtIYdk59pb2GJ7M?si=Ka2rAQv7TyqiC9wvGwERpA💜 Follow on Apple Podcasts - https://podcasts.apple.com/ie/podcast/the-giants-shoulder/id1752486249Download my FREE EBook 26 Neuroscience Books for 2026 HERE: https://thegiantsshoulder.com/

Dr. Erik Bekkers is an associate professor in Geometric Deep Learning at the University of Amsterdam, an ELLIS Program Director, and one of the most original thinkers working at the intersection of mathematics, AI and consciousness.He reverse-engineered how the human visual cortex processes reality using the geometry of curved spaces — then used those same principles to build AI architectures that outperform standard deep learning. He recently published a paper arguing that AI will never be conscious, introducing a framework called Biological Idealism.Expect to learn why your brain lifts reality into a higher-dimensional space just to see a straight line, what autopoiesis is and why it might be the dividing line for consciousness, why psychedelics decreasing brain activity while increasing experience is a problem for materialism, why firing neurons are an appearance of experience not the cause of it, why AI leaders claiming machines might be conscious is dangerous, and much more...Timestamps:00:00 Why Erik Wrote the Biological Idealism Paper02:00 The Materialist Bias in Society04:23 Does a Machine Have Consciousness?06:29 Can You Be a Materialist and Value Experience?08:24 The Map vs The Terrain: What is Matter Really?11:03 Bernardo Kastrup and the Path to Idealism14:11 Psychedelics: Less Brain Activity, More Experience?15:57 The Idealist Explanation of Neural Correlates19:54 What Primes Someone Towards Idealism or Materialism?24:17 Autopoiesis: The Self-Creation of Life27:32 How Autopoiesis Works in an Idealist Framework33:30 Where Physicalism and Idealism Actually Agree41:15 Finding Common Ground Across Metaphysics47:17 Why Are Some Creatures More Conscious Than Others?50:18 Donut-Shaped Geometry in Brain Activity54:46 Can Mathematics Ever Model Consciousness?59:33 The Geometry of Experiences Explained01:04:31 Continuity of Brain Structures Across the Animal Kingdom01:06:03 Can We Make a Machine Autopoietic?01:09:37 The Robot That Plugs Itself In: Is That Consciousness?01:14:00 What Would You Do With 100 Billion Dollars?01:20:20 Will We Ever See a Conscious Machine?01:24:11 AI Propaganda and Emotional Manipulation01:27:56 Hinton and Amodei: Is It Dangerous to Call AI Conscious?01:31:43 The Ethics of Machine Consciousness Research01:35:39 Animal Suffering, AI Spending and Asking the Right Questions01:38:10 Closing Thoughts and Anna Ciaunica's Influence...Email for sponsorship enquiries: evan@thegiantsshoulder.com ❤️ Subscribe to our main channel - https://www.youtube.com/@thegiantsshoulder?sub_confirmation=1💚 Follow on Spotify - https://open.spotify.com/show/5m3Gta5MtIYdk59pb2GJ7M?si=Ka2rAQv7TyqiC9wvGwERpA💜 Follow on Apple Podcasts - https://podcasts.apple.com/ie/podcast/the-giants-shoulder/id1752486249Download my FREE EBook 26 Neuroscience Books for 2026 HERE: https://thegiantsshoulder.com/

Chris Frith is a pioneering neuroscientist who helped launch the field of cognitive neuroscience — and his work has completely changed how we understand reality, consciousness, and mental illness.In this episode, you’ll learn why perception is just a controlled hallucination, how our brains build reality through social connection, why people with schizophrenia see the world differently, how consciousness evolved to help us coordinate with others, and why your sense of self might be an illusion shared to stay sane.Timestamps: 02:12 What Is Consciousness?

Dr. Julian Barbour is an independent theoretical physicist who has spent over sixty years working from a 17th-century farmhouse in Oxfordshire on the deepest question in physics — what is time? His answer: it doesn't exist.He completed the project Newton declared impossible and Einstein never finished, built two bestselling books around it, and at 88 remains one of the most original thinkers alive.Expect to learn why the Wheeler-DeWitt equation implies the universe is frozen and nothing evolves, what Shape Dynamics is and why only ratios and relations are real, why your brain is a "time capsule" containing the complete illusion of a past, how consciousness might add all the colour and motion to a bare mathematical skeleton, why Newton's gravity might secretly be a theory of variety, and why Barbour believes quantum mechanics itself could be replaceable, and much more…Timestamps: 00:00:00 What Is Time?

Matt Segall is a process philosopher, Associate Professor at the California Institute of Integral Studies in San Francisco, and author of Physics of the World-Soul and Crossing the Threshold — two books arguing that consciousness isn't produced by the brain but is woven into the fabric of reality itself.Expect to learn why there is no scientific evidence that consciousness exists, how one French philosopher broke Western science in 1637 and we still haven't fixed it, why the brain is a condition for consciousness but not the producer of it, what panpsychism actually claims and why it's making a serious comeback, why the hard problem of consciousness and the origin of life might be the same problem, what it might feel like to be water or a photon, how psychedelics reveal something philosophy has been saying for centuries, and much more…Timestamps: 00:00 The Nature of Consciousness02:52 Evidence and Experience06:09 Consciousness and the Brain09:09 Emergence vs. Production of Consciousness12:11 Panpsychism and Process Philosophy15:08 Information and Consciousness17:47 Biopsychism and Early Consciousness21:11 The Hard Problem of Consciousness24:08 Subjectivity and Objectivity27:06 The Role of Information in Reality29:47 Consciousness and the Universe48:25 The Relational Nature of Truth51:10 Beyond Space and Time54:55 The Self in a Panpsychist View56:30 The Evidence for Panpsychism01:00:01 Sociological Influences on Worldviews01:03:34 Psychedelics and Consciousness01:10:56 Navigating Reality and Hallucination01:15:13 Falsification and Progress in Panpsychism01:19:57 The Ethical Implications of Panpsychism...Email for sponsorship enquiries: evan@thegiantsshoulder.com ❤️ Subscribe to our main channel - https://www.youtube.com/@thegiantsshoulder?sub_confirmation=1💚 Follow on Spotify - https://open.spotify.com/show/5m3Gta5MtIYdk59pb2GJ7M?si=Ka2rAQv7TyqiC9wvGwERpA💜 Follow on Apple Podcasts - https://podcasts.apple.com/ie/podcast/the-giants-shoulder/id1752486249Download my FREE EBook 26 Neuroscience Books for 2026 HERE: https://thegiantsshoulder.com/

Matt Ridley is an evolutionary biologist, bestselling science writer and author of eleven books including The Red Queen, Genome, The Rational Optimist and Viral: The Search for the Origin of COVID-19.He co-investigated the origin of SARS-CoV-2 with molecular biologist Alina Chan — and what they found may be the biggest cover-up in the history of science. A secret Pentagon proposal describing the exact genetic manipulation that may have created the pandemic. Private messages showing virologists publicly denying a lab leak while privately admitting they thought it was likely. And an establishment that chose silence while millions died.Expect to learn what a furin cleavage site is and why it stunned virologists worldwide, what the secret DEFUSE proposal reveals about the experiments happening in Wuhan, why the virus was suspiciously well-adapted to human lungs from day one, what the recently released Epstein files reveal about how a convicted sex offender directed research at Harvard and compromised elite science, why no major funding body has investigated the lab leak despite 25 million deaths, and much more…Timestamps:00:00 The Origins of COVID-19: A Lab Leak Theory03:11 Investigating the Wuhan Institute of Virology06:00 The Role of Genetic Engineering in Virus Research09:08 The Furin Cleavage Site: A Key to Infectivity11:58 The Defuse Proposal: A Shocking Revelation14:51 The Pangolin Narrative: A Red Herring?18:10 The Call for Transparency in Science33:16 Controversies in Virus Origins35:35 Evaluating Zoonotic Narratives37:30 The Role of Markets in Virus Transmission40:22 Lab Leaks vs. Natural Origins42:05 Genetic Manipulation and Furin Cleavage44:42 Passaging Theory and Virus Evolution49:10 Implications of High Infectivity51:22 Suspicion of Early Vaccine Development54:48 The Need for Transparency56:24 The Future of Gain of Function Research01:00:57 The Lab Leak Hypothesis: Recklessness in Research01:10:01 Trust in Science: The Impact of COVID-19 on Public PerceptionEpstein01:20:20 Epstein's Influence: Compromising Science and Ethics01:23:32 Reforming Science Funding: Addressing Systemic Issues...Email for sponsorship enquiries: evan@thegiantsshoulder.com ❤️ Subscribe to our main channel - https://www.youtube.com/@thegiantsshoulder?sub_confirmation=1💚 Follow on Spotify - https://open.spotify.com/show/5m3Gta5MtIYdk59pb2GJ7M?si=Ka2rAQv7TyqiC9wvGwERpA💜 Follow on Apple Podcasts - https://podcasts.apple.com/ie/podcast/the-giants-shoulder/id1752486249Download my FREE EBook 26 Neuroscience Books for 2026 HERE: https://thegiantsshoulder.com/

Philip Ball is a former Nature editor of 20 years and the author of over 30 books spanning quantum physics, consciousness, and the strange frontiers of biology. In How Life Works, he argues that everything we’ve been taught about life — genes, blueprints, biological machines — is deeply incomplete.Get How Life Works: https://amzn.to/46dQRMlBiology isn’t built from instructions. It’s built from self-organising systems that sense, evaluate, predict and act. Cognition didn’t start with brains. Purpose isn’t mystical. And causation may not live where we think it does.Expect to learn why genes aren’t in control, how cells make decisions without neurons, what combinatorial explosion means for biology, why self-organisation shapes development, how agency emerges from physics, and what all of this means for consciousness — and much more…Timestamps00:00 The Evolution of Biological Understanding04:54 Rethinking Genes and Their Functions10:59 The Complexity of Biological Systems15:50 Metaphors in Biology: The Need for New Narratives25:12 Robustness in Biological Systems30:26 Hierarchies and Interactions in Biology35:36 The Impact of Genetic Mutations38:09 Redundancy and Compensation in Biological Systems39:26 Understanding Noisy Cellular Activity43:53 The Role of Noise in Cell Differentiation46:45 Navigating Developmental Landscapes49:48 Canalization and Robustness in Biology53:27 The Dynamics of Energy Landscapes in Biology57:01 Self-Organization and Developmental Goals01:00:52 The Interplay of Genes and Non-Equilibrium Systems01:10:54 The Limitations of Genetic Metaphors01:12:36 Understanding Causal Emergence01:15:19 Neural Networks and Causal Power01:17:29 The Complexity of Protein Functions01:21:05 Cognition Across Biological Systems01:23:32 The Future of Biology Education01:29:30 Rethinking Genetic Determinism01:33:17 Agency and Meaning in Biology01:44:40 Continuity of Agency in Biological Systems01:47:02 Defining Genuine Agency in Proteins01:50:55 Exploring Sentience and Awareness in Cells01:56:53 Ethical Considerations in Generative Biology01:59:51 The Future of Synthetic Biology and Regulation...Episodes MentionedMeet the MIT Neuroscientist Showing Brain Waves Are the Secret Engine Behind Consciousness: https://youtu.be/7OFb-NG3jIwMeet the Scientist Creating New Forms of Synthetic Life!
