Do you know the five main senses we have? They are touch, taste, sight, smell and hearing. They are controlled by different parts of our brains. So we call the brain our built-in "BeiDou". Brains help our bodies work smoothly. Try this: close your eyes and touch your nose. It's easy, right? That's because our brains can receive messages about where our body parts are. We can also stand on one leg without falling down. If we lose our balance, our brains will give us orders to fix it.

. Tests show that people see spider pictures faster than flowers. Some researchers also found that people react to loud noises faster than to a friend's voice. Scientists aren't completely sure about the reasons. Some suggest that this skill might come from ancient times. Our ancestors were often faced with predators. So they had to protect themselves from dangerous animals like spiders and tigers, or they would lose their lives. Until today, we still jump at sudden noises or shadows (影子) in dark rooms.
Here is more about brains. Can you imagine seeing colours when you hear music, or tasting candy when you see the sunshine? It's called sense mixing. Scientists think this happens when different senses intermingle (相互交织). Another fact is that temperature sometimes influences our senses. Some people can feel storms coming through knee pain. So we often joke that we're "human weather apps". Also, our brains are able to make adjustment (调整) to some senses. If someone can't see well, his hearing or touch might become stronger.
Though scientists have done much research on the brain, there's still a lot to do. Have you ever wondered why some people are better at sports? What's the secret to improving memory? Then it's time for you to start your discovering journey.
