Why are some of the best musicians blind? Can blind people learn how to echolocate, like a bat? What do your nightly dreams have to do with the rotation of the planet? Once we find alien life on other planets, should we expect that aliens have dreams at night? Find out why dreaming might be the strange lovechild of brain plasticity.

What do charlatans have to understand about human perception? Why are you so bad at recognizing a real penny among fakes? What did Eagleman have to do with the redesign of the Euro, and why did he campaign to the European Central Bank that all their bills should be blank with a single hologram in the middle?

We all have goals, and we all face temptations that get in the way. So what's happening in the brain when we act in a manner that isn't in accordance with who we want to be? Computers don’t have these problems, but being human can be tough. In the previous two episodes we exposed the rivaling networks battling it out under the surface. Today we’re going to talk about the gap between what you intend to do and what you actually do when temptation is there. 

What’s happening when you stand in the supermarket aisle and stare at the shelf full of options? It may not look like there’s much going on from the outside, but inside there’s a war of networks raging. How is your brain's decision-making influenced by price, emotions, and your group of friends? How would you choose between a nice candle and a chocolate bar in the shape of a computer keyboard? And what does any of this have to do with Starbucks or Tiger Woods or Burger King? 

Modern AI is blowing everyone’s mind. But is it intelligent like humans, or is it just playing impressive statistical games?

Traditional tests for intelligence (Turing test, Lovelace test, etc) have long been surpassed, so Eagleman proposes a new kind of test.
