A myth is something that is not correct, but many people believe it. There are a lot of myths about the human brain.
One of the biggest myths is that we only use 10% of our brains. The next part of the myth is that if we can learn to use the rest of our brains, then we'll be much smarter. People say this all the time, but it's completely not true!The truth is that although we don't know everything about the human brain, we know that each part of it has an important function （功能） . Modern scientists think the "10% myth" silly.
The other most popular myth is about being "right brained" or "left brained". According to this myth, people who use the right side of their brains are more artistic and creative. People who use the left side of their brains are better at math and science.Thisis as popular as the 10% myth, and it's also wrong. In 2013, a study at an American university tested the right brain and left brain myth. The study shows we use the left brain as much as the right brain.
It's true that we use different parts of our brains for different things. We use our left side for language more, and our right side when we need to pay attention. But there is no evidence （证据） that creative people use the right side more or that scientific people use the left side more.
We've talked about myths, so let's look at a few interesting facts about the brain. First of all, the brain feels no pain. Second, about 75% of the brain is made of water. It's also the fattest organ （器官） in your body. Here's another interesting fact about the brain. Around the time you turn 18 years old, it stops growing.
