Ep89 "Why do you love some flavors and not others?"

Inner Cosmos with David Eagleman ·

2025/01/27

Why do you like the taste of things that your friend doesn't? Why do kids not like coffee but adults do?

Inner Cosmos with David Eagleman ·

2025/01/20

Why is it so difficult to define intelligence? What does this have to do with being a fish in water trying to describe water? Might we humans possess one kind of intelligence in a constellation of many other types? And what does this have to do with empathy, AI, and our search for extraterrestrial life? Join Eagleman with guest Kevin Kelly as they dive intowhether there might exist very different kinds of minds.

Inner Cosmos with David Eagleman ·

2025/01/13

Because visual signals take time to process, we live slightly in the past. So how do we ever catch a baseball? And what does this have to do with certain visual illusions, or the view in New York City, or the things you were never taught in school, or the warp drive in Star Trek? Join Eagleman this week for a mind blowing look at the strange relationship between vision and time.

Ep86 "What are emotions?"

Inner Cosmos with David Eagleman ·

2025/01/06

Are emotions something that happen to you, or are they bodily signals we interpret? Does everyone show emotions in the same way -- that is, are there particular markers of the face or the body that always mean anger, sadness, or joy? And what does this have to do with Charles Darwin, the truth about facial expressions, or the movie Inside Out? Join Eagleman with this week's guest, neuroscientist Lisa Feldman Barrett, author of hundreds of papers and "How Emotions are Made", for a deep dive into the

Why are our brains so wired for love? Could you fall head over heels for a bot? Might your romantic partner be more satisfied with a 5% better version of you?

What do charlatans have to understand about human perception? Why are you so bad at recognizing a real penny among fakes?

Ep85 "What is a Thought?"

Inner Cosmos with David Eagleman ·

2024/12/16

Brains bear thoughts like apeach 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 life.

Inner Cosmos with David Eagleman ·

2024/12/09

How can we understand music's effect on human brains? Is music universal or does it rely on your experiences? How is music similar to a language? Can music be leveraged to help anxiety, dementia, or Parkinson's disease? What does any of this have to do with Stevie Wonder on the high hat, or the relationship between music and color? Join Eagleman with guest Daniel Levitin -- neuroscientist, musician, and author of This Is Your Brain on Music and I Heard There Was A Secret Chord.

Inner Cosmos with David Eagleman ·

2024/12/02

Does our sense of self emerge from our brain's skill at lumping things into unchanging categories? What can we learn watching a caterpillar brain transition to a butterfly brain? Can we think of a memory as a pattern that stays alive and has its own life? Does an ant colony have a sense of self? Join Eagleman and biologist Michael Levin at Tufts – one of the most energetic and original thinkers in the field -- to dive into new territories of the self.

Inner Cosmos with David Eagleman ·

2024/11/25

Every cell in your body changes, so why do you have a sense of continuity of the self – as though you're the same person you were a month ago? What does this have to do with the watercraft of the Greek demigod Theseus, or the End-of-History illusion, or why you go through so much trouble to make things comfortable for your future self, even though you don't know that person?

Ep 81 "How close are we to longevity?"

Inner Cosmos with David Eagleman ·

2024/11/18

Two certainties are death and taxes; a third is that people will work hard to avoid them both. But why is it so difficult to extend our lifespan? We know how to do it in worms and mice; why is it tricky in humans? Why do so few companies study longevity? What does the near future hold? What would it be like if everyone lived a much longer life? Join Eagleman this week with longevity expert Martin Borch Jensen to discuss the hopes and challenges of longevity science.

Inner Cosmos with David Eagleman ·

2024/11/11

Why do brains dream, and why are dreams so bizarre? Why doesn't your clock work in your dreams? And even though you spend much of your working day looking at your cell phone and computer – why do they almost never make appearances in your dream content? Is dream content the same across cultures and across time? Are dreams experienced in black & white, or in color? Are dreams the strange love child of brain plasticity and the rotation of the planet? What is the relationship between schizophrenia

Inner Cosmos with David Eagleman ·

2024/11/04

What is depression? Why are brains able to slip into it? Is depression detectable in animals? Do animals have options beyond fight or flight? And what does any of this have to do with measuring depression medications in city water supplies, reward pathways in the brain, the prevalence of tuberculosis, and zapping the head with magnetic stimulation? Join today's episode with David Eagleman and his guest -- psychiatrist Jonathan Downar -- for a deep dive into the brain science behind depression and

Why can you hear some sounds two different ways, depending on which word you’re looking at? Why do electrical outlets sometimes look like a face?

Inner Cosmos with David Eagleman ·

2024/10/21

When he was a child, Eagleman fell off a roof and time seemed to run in slow motion. When he became a neuroscientist, he grew curious about the experience and collected hundreds of similar stories from others. But is it true that your brain can actually see in slow motion, like Neo in the Matrix? And how would you test that? Hear how he dropped volunteers from a tower to put the science to the test, and what the answer reveals about our perception, memory, and experience of the world.

Ep80 "What's it like to never forget?"

Inner Cosmos with David Eagleman ·

2024/10/14

What would it be like to have a vastly better memory than you do now? What if you could remember what you were wearing on any day a dozen years ago? Or who you were with, what the conversation was, and whether it rained? Would it be a blessing or a curse? And if you’re forgetting a lot of your life, what might you do to better remember it? Join Eagleman with actress Marilu Henner, one of only dozens of people in the world diagnosed with highly superior autobiographical memory.

Inner Cosmos with David Eagleman ·

2024/10/07

When you imagine something -- like the sun peeking over a mountain during an early morning rainstorm -- do you see it with rich visual detail, or instead with very little internal picture? In an earlier episode we tackled the spectrum of visual imagination, from hyperphantasia to aphantasia -- and in this episode we dive even deeper with guest Joel Pearson to surface the most surprising differences between people's internal lives. How does your experience differ from other people's, and how does
