Ep9 "What does eating that cookie have to do with the hero of the Trojan war?"
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.

Ep8 "How does your brain decide what to buy?"
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?

Ep7 "Is AI truly intelligent? How would we know if it got there?"
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.

How can we build robots that simply figure themselves out?
