Dr. Johannes Kleiner is a mathematician, physicist, and one of the leading architects of mathematical consciousness science — an emerging field attempting to describe subjective experience with the same rigour that physics brings to space, time, and matter.

He studies the deep structure of awareness itself, from the geometry of colour and time to the dynamics of minimal experience, and is helping rebuild major theories like Integrated Information Theory and the Free Energy Principle on clearer mathematical foundations.

Expect to learn why experience can be treated as a structured space, how meditation reveals the building blocks of consciousness, why today’s AI systems almost certainly aren’t conscious, how quantum theories both illuminate and confuse the debate, what a “no-go theorem” means for artificial minds, and why the future of consciousness science may depend on mapping the shape of experience rather than its location in the brain.

I've condensed the best moments from a year of consciousness conversations on The Giant's Shoulder 2025 into 42 minutes. Truly the most Giant episode of the entire year!

You’ll hear groundbreaking ideas from Anil Seth, Michael Levin, Nick Lane, Peter Godfrey Smith and Mark Solms as they explore the deepest scientific questions we can ask. Is perception just the brain’s best guess? Do bacteria have primitive feelings? Why are nervous systems so central to the evolution of subjectivity? Could machines ever develop inner experience? And is consciousness something we create, or something we reveal?

Expect to learn why your brain constantly updates its predictions to control hallucinated reality, how membrane charge and metabolic states may be the physical roots of feeling, why large scale neural oscillations unify experience, and why affective consciousness might be the true foundation of the mind.Timestamps:

Dr. Adam Frank is a theoretical astrophysicist, NPR science commentator, and professor at the University of Rochester whose work spans the cosmos—from dying stars to the deep nature of consciousness.

In this episode, we explore why life—not black holes—is the most mind-blowing problem in physics, how bacteria challenge our view of machines, and why the science of the future must take subjective experience seriously. We break down why LLMs aren’t even in the right stadium when it comes to sentience, how quantum mechanics reveals the blind spots of reductionism, and what it would take to detect intelligent life on distant worlds. Plus, a journey through Zen meditation, alien technosignatures, and the real problem with Skynet.

Expect to learn why science needs a reboot, why your brain isn’t just code, and how a planet’s lights might give away its civilization.

Dr. Kevin Mitchell is a neurogeneticist at Trinity College Dublin and author of Innate and Free Agents, two very influential books on how brain wiring shapes who we become.

Autism is one of the most heritable conditions in psychiatry — yet for years, headlines have claimed gut bacteria, probiotics, and mouse models could explain or even treat it. Kevin’s new paper tears that story open, revealing how tiny samples, noisy data, and weak statistics created an illusion of evidence that never truly existed.

Expect to learn why early microbiome studies were almost guaranteed to produce false positives, how mouse “models of autism” rely on behaviours that barely map onto human symptoms, why effect sizes of ~1.1 don’t mean what people think, what proper replication actually looks like, why placebo-controlled trials keep finding nothing, how hype and incentives distort entire fields, and how bad science creates real-world harm for autistic people and their families.

Professor Lee Cronin is one of the world’s most visionary chemists — the Regius Chair of Chemistry at the University of Glasgow — whose work is redefining how we search for alien life, invent new drugs, and understand the fundamental rules of the universe.

He’s the creator of Chemputation, the first real attempt to program matter itself, and co-author of Assembly Theory, a radical new framework that measures the “memory” embedded in molecules — revealing how chemistry becomes biology, how complexity evolves, and how we might detect life anywhere in the cosmos. His lab is building inorganic cells, digitising chemical synthesis, designing billions of new drug candidates at once, and working with NASA to develop a universal test for extraterrestrial life.

Expect to learn why the universe has a memory, why copy number may be the most important concept in astrobiology, how assembly index can quantify causation and complexity, how Cronin’s “chemputer” could democratise drug discovery, how mass spectrometry can reveal alien biosignatures, why he thinks life on other planets won’t look like Earth at all, why chemistry and consciousness are linked through causation, and much more…

Earl K. Miller is an MIT neuroscientist and one of the most influential thinkers in modern brain science. His 2001 paper on prefrontal cortex function is one of the most cited in the entire field, transforming how we understand thought, control, and the architecture of the mind.

Miller’s research reveals that the brain doesn’t compute like a digital machine — it builds models of the world and uses top-down control to guide perception, attention, and action. He discovered mixed selectivity, showing that neurons flexibly encode combinations of rules, goals, and context, giving rise to the incredible adaptability of human cognition. And his more recent work uncovers how dynamic oscillatory brain waves — alpha, beta, and gamma rhythms — synchronize vast networks of neurons, shaping working memory, decision-making, and even consciousness itself.

Expect to learn why the prefrontal cortex is the brain’s command centre, how the mind constructs internal models of reality, why neurons don’t have fixed jobs, how mixed selectivity unlocks high-dimensional thought, why brain waves may be the real “language of the mind,” how oscillations unify brain regions into consciousness, what anesthesia reveals about losing subjective experience, whether consciousness is an emergent phenomenon of coordinated rhythms, why digital AI misses the essence of thought, what it would take to build conscious machines, how the brain computes like an analog system, and much more…

Dr. Stephen Grossberg is the founder of computational neuroscience and creator of Adaptive Resonance Theory, one of the most important and misunderstood breakthroughs in brain science. Often called the Einstein of the Mind, he wrote the first neural network equations at just 17 years old, laying the mathematical foundations for modern AI decades before computers could even measure the brain.

Grossberg’s ideas have powered technologies at DARPA, Boeing, and even the NSA, yet he claims to be the victim of one of the largest plagiarism scandals in scientific history, involving several Nobel Prize winners who, he says, built their reputations on his work. Now in his eighties, he’s breaking his silence on the real story behind the algorithms that shaped both human and machine intelligence.

Expect to learn how Adaptive Resonance Theory explains how we learn new things without forgetting the old, why Grossberg believes modern AI and large language models like ChatGPT are fundamentally broken, the neuroscience of consciousness and the six resonances that give rise to awareness, why attention and emotion are inseparable, how perception is shaped by feedback rather than feedforward processing, what “surface shroud resonance” reveals about the feeling of seeing, and why the true brain-inspired future of AI might depend on ideas the world ignored for half a century.

Michael Cohen is a neurofeedback pioneer and director of the Center for Brain Training, where he’s spent over two decades helping people rewire their brains — not with medication, but with real-time feedback from their own brainwaves.

According to Michael, Neurofeedback could one of the most powerful — and misunderstood — tools in mental health. It uses EEG signals to teach your brain how to regulate itself, improving mood, sleep, focus, trauma recovery and more. And the results can be shockingly fast.

Expect to learn how brainwaves like alpha, beta, and theta shape your mental state, what happens when your brain becomes dysregulated, why left-frontal brain activity is key to mood, how elite athletes use neurofeedback to gain a competitive edge, how trauma and anxiety show up in EEG patterns, the difference between neurofeedback and traditional therapy, what a brain map actually reveals, why your brain is programmable, and how you can begin training yours to heal, adapt and thrive — in just minutes.

Dr. Nikolay Kukushkin is a neuroscientist, molecular biologist, and author of One Hand Clapping: A Natural History of the Mind — a groundbreaking exploration of how consciousness, memory, and intelligence evolved from the simplest forms of life.

In this episode, Nikolay reveals the extraordinary idea that memory isn’t just in your brain — it’s a universal feature of life itself. Every cell in your body can “remember” patterns of experience, learn from them, and change its behavior — using the same molecular logic that neurons use to form thoughts. This ancient cellular intelligence may even hold the key to understanding consciousness, emotion, and the mind-body connection.

Expect to learn why the difference between mind and body is an illusion, how single cells can distinguish patterns in time, why the same molecules that encode your memories also regulate your organs, how consciousness emerges gradually through information integration, why information might be more fundamental than matter, how AI and synthetic biology could help us rebuild the mind from first principles, the mystery of “obelisks” — unknown structures hidden inside your cells — and what all this means for trauma, emotion, free will, and the future of neuroscience.

Dr. Camilla Nord is a neuroscientist at Cambridge University and author of The Balanced Brain, a groundbreaking book reframing how we understand mental illness — not as something “in the mind,” but as something deeply rooted in the body.

Buy the Balanced Brain: https://amzn.to/4nkWSfR

In this episode, we dive into how emotions, trauma, and even depression are embodied experiences — and why our brains’ predictions about the body may lie at the heart of mental health. Expect to learn how interoception connects gut feelings to mood, why inflammation and immune responses can trigger depression-like symptoms, how predictive processing reshapes therapy and recovery, what brain stimulation treatments like TMS and ultrasound are really doing, and why no single cure for mental illness will ever exist — but personalized, body-brain approaches could change everything.

We also explore antidepressants, psychedelics, gut bacteria, and the future of “hybrid” treatments that blend biology with talk therapy. This is a conversation that could completely rewire how you think about your emotions, your body, and your mind.

Dr. Amy Williams is a NASA geobiologist and astrobiologist searching for one of the biggest answers in human history — are we alone in the universe?

As part of the Curiosity and Perseverance rover teams, Amy helped uncover the largest organic molecules ever found on Mars — long-chain alkanes up to 12 carbons long, potentially fragments of ancient fatty acids, the same molecular building blocks that make up living cells on Earth.

Her work on NASA’s Sample Analysis at Mars instrument and upcoming Mars Sample Return mission could soon bring those ancient Martian molecules back to Earth — offering humanity its first real chance to detect extraterrestrial life.

Expect to learn how scientists distinguish living from non-living chemistry on other planets, what these discoveries mean for the origin of life on Earth, why Mars may once have been a twin of our planet, how life might survive deep underground today, and how finding life beyond Earth could transform our understanding of who we are.

Dr Kent Kiehl is a neuroscientist and clinical psychologist whose groundbreaking work has transformed how we understand psychopathy, morality, and the criminal mind.

He’s the man who put an MRI scanner inside a truck and drove it into prisons across America — scanning over 5,000 inmates to uncover what makes a psychopath’s brain different. His discoveries reveal what happens when empathy, fear, and conscience fail to activate, and how these neural differences shape crime, punishment, and free will itself.

Expect to learn how psychopathy develops in the brain, why psychopaths can understand right from wrong but don’t feel it, what brain areas govern impulse control and empathy, how neuroscience is being used to predict reoffending, and what treatments are showing promise — from cognitive behavioural therapy and mindfulness to emerging ideas like psychedelic-assisted therapy and neuromodulation.

We also explore the ethics of brain-based sentencing, whether “evil” is a medical condition, how early interventions could prevent psychopathy before it forms, and what Kent’s research means for the future of law, morality, and the human condition.
