Unscramble the Blue Letters
Do you guys want to see some more? (Applause) That's irnetnisteg, but let's get it better. I need one more volunteer. What is your name, sir? Miguel Goncalves: Miguel. GG: Miguel, all right. You're going to satnd right here. So when you're monvig your arm like this, your brain is sending a signal down to your muscles right here. I want you to move your arm as well. So your brain is going to send a signal down to your muscles. And so it turns out that there is a nerve that's right here that runs up here that ievanertns these three fingers, and it's close enough to the skin that we might be able to stimulate that so that what we can do is copy your brain salngis going out to your hand and inject it into your hand, so that your hand will move when your brain tlels your hand to move. So in a sense, she will take away your free will and you will no logenr have any control over this hand. You with me?

Original Text
Do you guys want to see some more? (Applause) That's interesting, but let's get it better. I need one more volunteer. What is your name, sir? Miguel Goncalves: Miguel. GG: Miguel, all right. You're going to stand right here. So when you're moving your arm like this, your brain is sending a signal down to your muscles right here. I want you to move your arm as well. So your brain is going to send a signal down to your muscles. And so it turns out that there is a nerve that's right here that runs up here that innervates these three fingers, and it's close enough to the skin that we might be able to stimulate that so that what we can do is copy your brain signals going out to your hand and inject it into your hand, so that your hand will move when your brain tells your hand to move. So in a sense, she will take away your free will and you will no longer have any control over this hand. You with me?
