Ted Talk- 当你在做决策的时候，你大脑的变化

When you're making a deal, what's going on in your brain?

game theory neuroscience

• predict what people would like to do and what others are doing

brain: using game theory

• a group of players
  strategy: win if pick 2/3 * average win from number 1 to 100
• equilibrium in the analysis: everyone figures out what others people would like to do exactly ( the result is zero)
• scanning MRI while playing: playing with people/computer:
• scanning by the EGG in reaction
  compare the data on the cortex and the whole brain: when they are the delay and thinking about making the deal or not
• Compare to the uninformed brain and the informed brain: the uninformed brain reacts first and both of them react cross the brain, the reaction; after a period of time, when uninformed made the deal, they would react more when informed reacts at the small part

human 1.0: a bold idea

• chimpanzees are: faster, stronger and more status-assessed
• matcher between the chimpanzees in the game: find the rate of the match and mismatched (estimated the rate is 50% and 50%) after changing the payoff, they would avoid the another to choose the higher payoff
• after exercises several times, they use less on the brain and becomes lazy on action to get the reward

what did we learn?

• people naturally do 1-2 steps of strategic thinking
• use theory of mind regions
• chimps are 'better' competitors than human ( because they are more rational)
