David Papineau is a philosopher of mind at King’s College London and author of Thinking About Consciousness and The Metaphysics of Sensory Experience, a leading voice who has shaped today’s mind–brain debate from the academy to the airwaves.

He argues that consciousness isn’t something mystical added to the brain—it’s what the brain is doing—and that the “hard problem” is a conceptual trap that sneaks in dualism. In this episode, we put materialism on trial, stress-test it with neuroscience, and ask what it means for meaning, morality, animals, and AI.

Expect to learn the strongest arguments for why consciousness is not fundamental, how causal closure and mental causation actually work, why the hard problem may be a mirage, what Mary really learns when she sees red, how zombies mislead us, what aphantasia and inner speech reveal about the diversity of inner experience, where the boundary of consciousness might lie across animals, plants, bacteria—and even organs, whether AI could ever “care” and what architecture it would need, how perception might be qualitative beyond representation, what split-brain, blindsight, anesthesia and psychedelics teach us about the self, what evidence would falsify materialism, how to reconcile meaning and ethics without magic, and much more

Dr. Robert Plomin is one of the world’s leading behavioural geneticists and the author of Blueprint, a game-changing book that argues your DNA isn’t just important — it’s the blueprint of who you are.

Plomin’s groundbreaking twin studies revealed that nearly every psychological trait — from intelligence and personality to mental illness and addiction — is significantly heritable. Now, he’s at the forefront of a new revolution: polygenic scores that can predict your future from birth… or even before.

Expect to learn how polygenic scores are reshaping psychology and medicine, what your genome can reveal about your intelligence, mental health, and personality, why traditional ideas about nurture are collapsing, the shocking truth about educational inequality, how gene editing and embryo selection are becoming real-world tools, what role companies like Orchid play in designing future generations, why Elon Musk might be building babies in Gattaca labs, and whether free will can survive in a world where your genes know you better than you know yourself.

Dr. Ryota Kanai is a neuroscientist, AI entrepreneur, and CEO of Araya—lead investigator in Japan’s Moonshot to free humans from the limits of body and brain by 2050. He’s a pioneer of non-invasive brain–machine interfaces, the Internet of Brains, and architectures aimed at conscious AI, and he’s the author of Will AI Become Conscious?.Consciousness, he argues, isn’t magic—it’s the brain’s internal simulation engine. Kanai is turning that insight into technology: thought-controlled cybernetic avatars, emotion-aware robots that sense and respond to our feelings, and mind-to-mind links that could transform how we communicate, learn, and work.Expect to learn why the brain is a prediction machine and what that means for building conscious AI, how non-invasive BMIs already decode intent and where the big breakthroughs must come from, what the Internet of Brains actually enables beyond faster chat, whether “skill upload” is science or sci-fi, why cybernetic avatars might change jobs before they change bodies, how emotion robots read human states (and how not to be fooled by them), the simplest way to grasp the global workspace and free-energy ideas, how to test for machine consciousness without a Turing Test, what neurorights and “neural firewalls” should protect, the cultural differences shaping neurotech in Japan vs. the West, the milestones to 2030/2050, and much more…Timestamps: 00:00 Intro03:05 The Moonshot Goal: Liberating Humanity06:00 Understanding Brain-Machine Interfaces09:00 The Future of Thought Decoding12:01 Envisioning 2050: A Technological Landscape14:55 Connecting Brains to AI: Implications and Possibilities17:52 The Ethics of Neural Technology20:38 Adoption and Acceptance of Neural Implants23:46 Medical Applications vs. Augmentation26:46 The Future of Memory Augmentation29:54 Exploring Personality Modification32:45 Long-term Safety and Efficacy of Neural Implants35:38 General Purpose Neural Implants38:28 The Quest for Consciousness in Neural Technology47:47 Decoding Multimodal Information49:36 The Concept of the Internet of Brains51:50 Exploring Brain-to-Brain Communication54:18 Philosophical Implications of Consciousness55:21 Navigating Intrusive Thoughts in Communication56:42 Consumer Applications of Brain-Computer Interfaces58:30 Entertainment and Gaming in Brain-Computer Interfaces01:02:22 Potential of Non-Invasive EEG Devices01:04:18 Conscious AI: The Future of Machine Awareness01:10:05 Integrating Consciousness Research into AI01:18:09 Mathematical Definitions of Consciousness01:22:07 The Geometry of Experience and Consciousness01:27:51 Exciting Future Technologies in Brain-Computer Interfaces...Neuroscience Products I Swear By (Supports the Channel)Sentia Spirits: https://sentiaspirits.com/mcgloughlin4209355084Manta Sleep Mask: Get the Comfiest Sleep Mask on the Planet (Use Code GIANTSMANTA10 https://bit.ly/4ilzfBL )Brain.FM: Music Entrainment for Focused Deep Work (30 Day Free Trial: https://www.brain.fm/giantsshoulder)Consensus.AI: https://get.consensus.app/we00d2cmjpqeFollow My Neuroscience Podcast - The Giants Shoulder Spotify - https://open.spotify.com/show/5m3Gta5MtIYdk59pb2GJ7M?si=b33232eae67b4126Apple Podcasts - https://podcasts.apple.com/ie/podcast/brief-enquiry-to-the-brain/id1752486249

Professor Adam Zeman is a Neurologist at the University of Exeter and the scientist who coined the term aphantasia — the “blind mind’s eye” — after a patient suddenly lost the ability to visualize following heart surgery.

Since then, he has led the global investigation into why some minds picture nothing while others see in IMAX 8K, uncovering what this hidden spectrum of imagination reveals about memory, dreams, emotion, creativity, and even consciousness itself. He is also the author of Consciousness: A User’s Guide, A Portrait of the Brain, and The Shape of Things Unseen.

Expect to learn why up to 5% of people can’t form mental images, how hyperphantasia floods the mind with cinema-like detail, why imagination is our brain’s “default mode,” how differences in the mind’s eye shape autobiographical memory and emotional vividness, why aphantasics still dream in pictures, what hallucinations and delusions reveal about the creative brain, how imagination connects to empathy and storytelling, the cultural impact of naming aphantasia, and much more

Mark Solms is a neuroscientist, psychoanalyst, and author of The Hidden Spring, one of the most influential books on consciousness in recent years.He revolutionised sleep science by proving that dreaming isn’t confined to REM sleep, and he founded the field of neuropsychoanalysis — bridging Freud with modern neuroscience. Today, his radical claim is that consciousness begins not with thoughts in the cortex, but with feelings deep in the ancient brainstem.

Expect to learn why dreams are inseparable from consciousness, what dreaming reveals about the brain’s hidden functions, why feelings are the fundamental form of awareness, how cortical blindness can vanish in dreams, why consciousness is not optional but essential for survival, how the brainstem generates our inner life, whether AI could ever truly be conscious, and why the first computers that “give a damn” may be closer than you think…

Dr. Merlin Monzel is a neuroscientist and one of the world’s foremost researchers on aphantasia — the condition where individuals live without the ability to visualize mental images.

For decades, millions of people didn’t know they were missing anything — until science caught up. Dr. Monzel’s groundbreaking work is revealing what happens when the mind’s eye goes dark, and how it changes memory, emotion, identity, imagination, trauma, and even consciousness itself.

Expect to learn what mental imagery is really for, why people with aphantasia can still dream vividly, how missing imagery affects autobiographical memory and emotional recall, why traditional therapy might fail aphantasic patients, how aphantasia might protect against PTSD, how memory becomes a script instead of a scene, what brain scans reveal about connectivity between the hippocampus and visual cortex, whether imagination can be trained or restored, and why studying aphantasia may offer deep insights into the nature of consciousness — and what makes us feel like a self at all.

Dr. Nicole Rust is an emotion neuroscientist and author of Elusive Cures, a bold new book exploring why neuroscience still hasn’t solved brain disorders — and how we can change that.

Despite decades of research and billions of dollars spent, conditions like depression, anxiety, and schizophrenia remain without true cures. Rust argues that part of the problem is how we think about the brain — not as a simple domino chain of causes and effects, but as a self-looping, complex system more like a hurricane. Fixing it isn’t about finding a single “broken piece,” but about helping the brain relearn its way back to health.

Expect to learn why our traditional models of mental illness are flawed, how feedback loops in the brain make treatment harder, why emotions aren’t localized to one brain region, the staggering advances that now let scientists record from a million neurons at once, how psychedelics may unlock childhood-like plasticity, why pairing them with therapy is key, how AI is transforming neuroscience, the future of mental health research, and much more…
