Your neurons create and send more messages than all the phones in the world. And although one neumn creates only a little electricity, all your neurons together can produce enough electricity  to power a light bulb (灯泡).

   So exactly how fast does your brain work? Well, imagine this: a bee lands on your foot.  Neurons in your skin send this information to your brain at a speed of more than 240 kilometers per hour. Your brain then uses other neurons to send the message back to your foot to shake the bee off quickly. These neurons can send this information at more than 320 kilometers per hour. No computer has your hrain's unbelievable ability to deal with the amount of information coming from your eyes, ears and other sensory organs.

   But how does your brain allow you to leam things Lhat you will use in the future? The structure (结构) of your brain changes every time you have a new thought, remember or leam something. For example, riding a bike seems impossible at first, but soon you are able to do it. How? As you practice, your brain sends "bike riding" messages again and again Soon, the actions are learnt and you are able to ride a bike easily from then on.
