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? Today’s episode is a love story about our sense of touch: what it is, how it works, and why it plays such a critical role in our lives.

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

Neuroscientist and author David Eagleman discusses how our brain interprets the world and what that means for us. Through storytelling, research, interviews, and experiments, David Eagleman tackles wild questions that illuminate new facets of our lives and our realities.

How do brains picture things internally, and how might you and I imagine differently? How have recent discoveries completely changed the debate and the way we understand internal experience? What does this have to do with Disney's Fantasia, or Pixar's aphantasia? Strap in for some very wild surprises today about our internal experiences, with guest Ed Catmull, founder of Pixar Studios. 

Ep59 "Do you visualize like I do?"

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, composer Anthony Brandt, as they uncover the surprises about creativity.

Ep58 "What do brains teach us about whether AI is creative?"

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?

Ep57 "When should new technologies enter the courtroom?"

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.
