In humans, the brain also controls our use of language, and is capable of abstract thought. The brain is the control centre of the whole body. The brain is made up of a special type of cells.They are connected with each other and with the nerves in our body.he brain stem is at the back of the brain (actually underneath it in humans). It joins the rest of the brain with the spinal cord. It has lots of different parts that control different jobs in the body: for instance, the brain stem controls breathing, heartbeat, sneezing, eye blinking, and swallowing.
