Ep35 "What sticks in your brain and what doesn’t? " Nov 20, 2023

Show notes

f you look at a brain, how can you immediately tell if it belongs to a piano player or a violinist? How can a dog learn how to walk on its rear legs? And what does this have to do with expertise, or the good news about the brains of digital natives, or how governments respond to change just like brains do? While we all like to talk about brain plasticity, the truth is that most of what happens in your life makes no meaningful change to your brain. So what’s the difference between the stuff that sticks and the stuff that doesn’t?

Ep34 "What is intelligence?" Nov 13, 2023

Show notes

What would it be like to have a much lower or higher IQ than you currently have -- for example, to be a squirrel or an advanced space alien? This week's episode is about intelligence. What is it and what is its history and future? Join Eagleman on a whistle-stop tour of several schools of thought about what intelligence might mean in the brain.

Ep33 "Why do they start sprinters with a bang instead of a flash?" Nov 06, 2023

Show notes

Why do they use a gun at the Olympics? And why can you get off the blocks after the bang but still be disqualified for jumping the gun? Few things are as bizarre as our time perception. From sprinters to basketball players, from Kubla Khan to Oppenheimer, from television broadcasting to hallucinations, Eagleman unmasks illusions of time that surround us. Why does the brain work so hard to pull off editing tricks? And what does this tell us about our perception of reality?

Ep32 "Is death reversible?" Oct 30, 2023

Show notes

Does life end inevitably or instead only because we don’t understand biology well enough yet? Today’s episode is about understanding what happens when your molecular cycles grind to a halt... and whether there's anything we can do to hit control-Z. Join Eagleman and his guest Dr. Zvonimir Vrselja to dive into the weird possibility of understanding cells well enough to reverse death.

Eagleman answers listeners questions.

Ep31 "Why do we see #TheDress differently?" Oct 23, 2023

Show notes

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? How can you have rich visual experience with your eyes closed? Are some crosswalk buttons fake? Why are some pictures interpretable only once you’ve been told what to look for? And although brains are often celebrated for their parallel processing, what should they really be celebrated for? Tune in to learn what happens when the raw facts of the world collide with your expectations.

Ep30 "What does it mean to know thyself in the age of neuroscience?" Part 2 Oct 16, 2023

Show notes

Can we explain our rich experience of life only by studying the molecules that compose us? How is the color of your passport related to your chances of presenting with schizophrenia? Males are more predisposed to commit crime, so why don’t all males commit crime? And what does any of this have to do with traffic jams, why Seinfeld is funny, and how we’re ever going to come to know ourselves from studying biology? Join Eagleman to talk about levels of understanding, what a meaningful explanation would look like, and the possibility that we are not near the conclusion of science's journey, but instead near the beginning.

Ep29 "What does it mean to know thyself?" Part 1 Oct 09, 2023

Show notes

Did Joan of Arc turn the tide of the 100 Years War as the result of a brain disorder? Would you appreciate Taylor Swift if you only had an internal camera to watch her vocal chords? What do almost all drugs of abuse have in common? How can the tiny molecules of rabies virus control your behavior? Join Eagleman on a two-part deep dive into the fundamental question of how biological insights can shed light on the ancient question of who we are.

Ep28 "Does your language shape your thinking?" Oct 02, 2023

Show notes

Are there really dozens of words for snow in northern cultures? What did the movie Arrival have to do with language and cognition? Why are Russians better than Americans at distinguishing certain shades of blue? And what does any of this have to do with space, time, gender, and how your language influences your thought? Join Eagleman and his guest, cognitive scientist Lera Boroditsky, as they take a deep dive into the intersection of words and understanding.

Ep27 "Can we read brains at an airport to know who's going to bomb a plane?" Sep 25, 2023

Show notes

Can your thoughts be read with neurotechnology? When is measuring the brain like reading the mind? How close or far are we from being able to know if you're thinking about some particular thing you did or intend to do? What's hype and what's real? Join Eagleman for a deep dive into mind reading: what it means, where we are now, and whether your thoughts could ever be readable with new technologies.
