Inner Cosmos with David Eagleman

Would you eat a burger grown from a human muscle cell? Would you rather use your own cell or someone else's? What does the future of lab-grown meat illuminate about neuroscience, our calculations of morality, and whether your grandchildren will have a different answer? What does any of this have to do with endangered species, the sacred versus the profane, brain plasticity, moral positioning, social belonging, stepping on the bound...

What is code, and can it be thought of like a magic spell? Are we building a world so complex that we will lose the ability to understand its operations -- and has that already happened? What does any of this have to do with SimCity, or knowledge that already exists but no one has put together, or how coding will evolve in the near future? Join Eagleman with scientist Sam Arbesman, who has just written a book asking the question: w...

What is intelligence? If we look hard, can we find it in unexpected places: not just in brains but in all kinds of structures? How should we recognize it? And what does any of this have to do with a bipedal dog born without front legs, or making small new organisms out of single cells, or   how Wikipedia might be like an axolotl, or why we are so blind to the vast variety of minds that might surround us? Join Eagleman wit...

Can we explain consciousness as emerging from classical neuroscience, or do we require deeper principles? Could quantum physics have something to do with it? Is it possible that consciousness predates biology, and biology evolved to take advantage of it? What are the right ways to build new theories in neuroscience when we don’t know the answers? Join Eagleman with Nobel laureate Roger Penrose and anesthesiologist Stuart...

Brains bear thoughts like a peach tree bears peaches. Even for meditators it's almost impossible to stop the firehose of words and images and ideas. But what in the world is a thought, physically? How can you hear a voice in your head when there's no one speaking in the outside world? And what does any of this have to do with a small marine animal who eats its own brain? Join Eagleman for this week's deep dive into our inner l...

Is your brain a one-person show or an ensemble cast of rivaling neural networks? How do we manage the conflict between different drives, and what does this have to do with literature, deities, maturation, and what Nietzsche meant when he said “every drive wants to be master, and it attempts to philosophize in that spirit”? Join Eagleman this week with Jordan Peterson as we examine the way lives are built on conflicting ...

How do brains slip so easily from the real world into made up worlds? What do authors of great literature have in common with stage magicians and comedians? What does any of this have to do with cognitive shortcuts, prediction machines, Marcel Proust, Toni Morrison, Jane Austen, or why jokes are always structured in threes? Join Eagleman this week for a conversation with his Stanford colleague Joshua Landy as they discuss brains on...

Why do movies work so well? What does film reveal about the way the brain processes reality? What does any of this have to do with omniscience, simulation, jumping around in time, or why dogs don’t do story? Join Eagleman with guest Jeffrey Zacks, cognitive scientist at Wash U, as we dive into the peculiar magic that happens when the lights go down, the screen glows to life, and we find ourselves pulled into the wor...

Is AI an intelligent agent, or is there a different way we should be thinking about it? Is it more like a piece of cultural technology? What in the world is a piece of cultural technology -- and how would re-thinking this change our next steps? What does any of this have to do with the myth of the Golem, printing presses, Socrates, Martin Luther, or the story of stone soup? Join Eagleman this week with cognitive scientist Alison Go...

If you had to give a detailed description of what flits through your mind, how good would you be at it? Might you be surprised at how many of your thoughts don't involve language? Are your thoughts changed by paying attention to them? What does this have to do with getting surprised by a random beep and immediately writing down what you’re thinking? Join Eagleman this week in conversation with Russell Hurlburt, a clinica...

What enables some people to keep going when everything falls apart? We all know someone who’s been through hell and comes out standing. This episode is about resilience. Join Eagleman with guest Dr. Jonathan Downar to discover what happens in the brain when we face adversity. Is resilience something you’re born with, or is it something your brain can develop? What does any of this have to do with The Diving Bell and the...

What does The Matrix tell us about the brain and time perception? And what does that have to do with champion bicyclists, hidden data, elementary particles, secret murderers, or time machines? Today’s episode is about slow motion: what’s going on in the brain, and why we are so mesmerized by it. Whether watching a sword battle, basketball dunk, or sprinters, we're pulled to slow motion like moths to flame... but ha...
