NAME_1: Who wouldn't love acing a geography exam, remembering all the locations of the countries on a map or avoiding embarrassing situations of suddenly forgetting the person's name standing right in front of you. It turns out that memory, like other muscles in the body, can be strengthened and enhanced. But instead of practicing with flash cards, there may be an interesting way that we can hack our memory while we sleep.(Music)Why do we sleep? This has been a question asked since the early days of civilization. And while we may not know the exact answer, there are a number of really good theories about why we need it. Sleep is when the brain transfers short-term memories experienced throughout the day into long-term memories. This process is called memory consolidation, and it's the memory consolidation theory that has scientists wondering if we can enhance certain memories over others. There was a paper recently in the journal "Science" by NAME_2 and his colleagues at Northwestern that seemed to show that this may be true, and that piqued our curiosity. NAME_3 has been working on a DIY version of this task to see if we can improve memories through the use of sound in sleep. So NAME_3, how do you test if we can improve our memories with sleep?NAME_3 Marï¿½i: We need a human subject.[Step 1: Play a game] We have a memory game that we have on an iPad, and then we make our subject play this game and remember the images and where they appear on the screen.GG: So this is like a memory game you used to play as a child, which picture was where. And we tie each picture with a sound that represents it.JM: So, if you can see a picture of a car, for example, and you would hear the car engine.(Car engine starting)GG: Just before you go to sleep we're going to test you. We're going to see how well you remember where the pictures are. Every time you see the picture, you're going to hear the sound. And now comes the experiment. You're going to go take a nap. [Step 2: Take a nap] And while you're sleeping, we're going to be recording your EEG.JM: And then we wait for them to go into what's called the slow-wave sleep, which is the deepest phase of your sleep where it's really hard for you to wake up.GG: OK, pause. So, here's some information on sleep. Write your response with exactly 2 paragraphs, separated with the markdown divider: ***.
