우리 몸에서 가장 중심이 되는 부분을 뇌라고 할 수 있을 것이다. 뇌는, 인간 진화의 산물 중 가장 위대한 것 중 하나였다. 인간 진화의 산물을 예로 들면, 이족 보행, 커다란 두뇌, 입체적인 시각 등이 있다. 뇌란, 몸 전체의 체적량 대비 크기가 두뇌의 상대적인 크기라고 한다. 인간은, 모든 동물중에서 가장 커다란 두뇌를 가지고 있다. 이 뛰어난 능력을 가진 덩어리를 분석해본다. 

The bulging brains are the bundle of nerves, the brain in the cover said. Yes, there are thousands billions of brain cells called neuron. We lost 1.1 millions of brain cells a year, but don't worry. They are just really small part of our body. 

Brain use the most calories in our body. We can prove it because our head is the hottest part of our body, So, why brain have to use a lot of energy? Because this works are really hard. You should know that the transmission of impulse require energy. I told you, there are billions of brain cells. Maybe exercising needs much energy, but when you solve math problem, I know that you are using much more energy by your brain than exercising hard. 

There are several parts at brain. The cerebrum is the biggest part of our brain. It does a lot of things. When you think of something hard or strange, than this biggest part works fast. Yes, cerebrum save memories and high thinking action. The cerebellum is the hind brain. It regulate balance of our body. The midbrain, the interbrain, the afterbrain... they are all important part of body that controls our body.
