The comparison of brain sizes

The brain with a hand

The brain is the part of the body which lets living beings think. It does some bodily functions, such as telling the rest of the body what to do.

It gets input from sense organs, and changes behavior in response to this information. In humans, the brain also controls our use of language, and is capable of abstract thought. The brain is the main control centre of the whole body. The brain is made up of special cells called nerves, which are connected with each other and with other nerves in our body.
