Inner Cosmos with David Eagleman ·

2024/05/13

From a neuroscience point of view, what is creativity? How does it shine light on the current lawsuits over large language models and whether they produce anything fundamentally new... or are simply remixing the old? How do the arts expose something important about what's happening in the human brain? What do we know about the cultural evolution of ideas? And what does any of this have to do with how cell phones got their names, and why koala bears don’t write novels? Join Eagleman and his guest,

Ep57 "When should new technologies enter the courtroom?"

Inner Cosmos with David Eagleman ·

2024/05/06

Can we measure a lie from a blood pressure test, or pedophilia from a brain scan? And how should a judge decide whether the technology is good enough? What does this have to do with Ronald Reagan, or antisocial personality disorder, or how the television show CSI has impacted courtrooms? Today’s episode lives at the intersection of brains and the legal system. When are new neuroscience techniques allowed in courts, and when should they be?

Inner Cosmos with David Eagleman ·

2024/04/29

David is taking his birthday week off and wanted to re-share this episode due to it's ongoing relevance.Modern AI is blowing everyone’s mind. But is it intelligent like humans, or is it just playing impressive statistical games? Could AI reach or exceed our level of intelligence, and how would we know when it gets there? Traditional tests for intelligence (Turing test, Lovelace test, etc) have long been surpassed, so Eagleman proposes a new kind of test.

Ep56 "Why do we care so much about touch?"

Inner Cosmos with David Eagleman ·

2024/04/22

Why does a cold pool feel warmer the second time you dip your toes in? Why does a safecracker run his fingers over sandpaper? Why do Mediterranean cultures touch each other more than Scandinavian cultures? Would it be great -- or not so great -- if you were unable to feel physical pain? Why does stubbing your toe have different sensations through time? And what does any of this have to do with cuddle puddles, NBA players bumping chests, or puppies sleeping in dog piles?

Inner Cosmos with David Eagleman ·

2024/04/15

Could you instantaneously learn to fly a helicopter -- not by practicing, but instead by uploading instructions directly to your brain? What would society do if children no longer had to go to school? And what does any of this have to do with suntan booths, nanorobots, or what a cowboy on a hill is not able to see? Join Eagleman to learn about the possibility of modifying the microscopic structure of your brain and leapfrogging education. What are the possibilities, the caveats, and the unexpected

Inner Cosmos with David Eagleman ·

2024/04/08

From the brain’s point of view, what is the self? How do 30 trillion cells come to feel like a single entity? Does the "self" of a blind person include the tip of her walking stick? How flexible is our sense of self? And what does any of this have to do with psychedelics, trauma, synchronized swimmers, religious rituals, cheerleaders, or why soldiers across time and place love to march in lockstep?

Ep 53 " Can societies fight better? "

Inner Cosmos with David Eagleman ·

2024/04/01

Presumably we're not going to solve the problem of conflict between groups of people -- but what would better conflict look like? And what does that have to do with brains, the spread of homo sapiens, social media recommender algorithms, tribalism, intellectual humility, or the Iroquois Native Americans? Join this week's episode with guest Jonathan Stray -- a conflict researcher -- for an episode about brain science, war, empathy, outgroups, and how we might do better.

Inner Cosmos with David Eagleman ·

2024/03/25

Can you become conscious inside a dream? Can a researcher convey information to a dreamer, and can the dreamer find some way to answer back? Does 10 seconds inside a dream equal 10 seconds in real life? Could taking a drug inside a dream give you a placebo effect? Can you prompt your brain like a large language model? And if so, what would you pose to your unconscious brain? Join David Eagleman and guest Jonathan Berent to discover the what, why, and how of lucid dreaming.

Ep 51 "Why do brains dream?"

Inner Cosmos with David Eagleman ·

2024/03/18

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 ·

2024/03/11

Why do we spend 1/3 of our lives in the strange doppelganger state of sleep? Can we die from a lack of sleep? How long is it possible to keep yourself awake (and why does the Guinness Book of World Records no longer track that)? Why are some people night owls and some morning larks? What does any of this have to do with lightless underground caves, or with the length of a day on Mars? Join this week's episode to learn everything you've ever wanted to know about sleep and what your brain is actually

Ep49 "Can you read the brain to detect a lie?

Inner Cosmos with David Eagleman ·

2024/03/04

Could you get convicted of a crime based on your brain activity? Are brain scan lie detectors accepted in court, or would that count as illegal search and seizure? And what does this have to do with your mouth getting dry, the orbits under your eyes getting hot, and your voice constricting when you deceive? Join Eagleman to dive into the fascinating topic of whether societies can use technology to figure out whether a person is telling the truth -- and under what circumstances we would even want to

Inner Cosmos with David Eagleman ·

2024/02/26

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?

Do our visual systems see in frames like a movie camera or instead analyze the world continuously? Why do you see multiple hands when you clap under yellow street lamps? How did Hollywood launch from the question of whether all four legs of a galloping horse come off the ground at once?

Inner Cosmos with David Eagleman ·

2024/02/12

Can a person be declared legally dead even though he is very much alive? In December of 2010, why did a number of families choose to pull their loved ones off life support just before the new year? How do doctors decide when you've died, and how is it different from how lawyers decide? How is death a process rather than an event? What does any of this have to do with getting buried alive, your family's religious beliefs, or whether a head stays alive after the guillotine? Join Eagleman and guest

Inner Cosmos with David Eagleman ·

2024/01/22

How do billions of neurons store your home address, your ability to ride a bike, and the history of your life? How does memory work in the brain, and how is it different from the way a computer stores information?

Inner Cosmos with David Eagleman ·

2024/01/15

What role will AI play in the future of fake news and misinformation? What does this have to do with our brains’ internal models, with voice passwords, and with what Eagleman calls "the tall intelligence problem"?

We all worry about fake news. But is misinformation and disinformation really new? Join Eagleman for a deep dive into the past, present, and future of truth. Why do cameras not tell us what we think they do? What should we not forget about pamphleteering? And what does this have to do with agriculture in the USSR, or book banning in America, or dog whistles, or apps that only tell facts? And why is it so hard to understand the viewpoints of millions of brains at once? This week's episode is the
