What keeps you thinking, moving, and breathing-even while you sleep? From the moment you wake, your brain is working behind the scenes. As you see the room and hear voices around you, it takes in information and helps you make sense of it. Through the day, it helps you learn, remember, make choices, and guide your movements. It also helps control breathing and emotions, alongside other parts of your body. How does it do so much? Your brain contains billions of neurons-tiny cells that pass messages using electrical and chemical signals. But the work doesn't stop when the day does. While you sleep, your brain stays active, helping organize memories from what you've experienced. So what keeps you going through the day and night? Your brain does-helping you think, move, and breathe by day, and staying active while you sleep.
