What is the brain?

The brain is an organ inside the skull.
It forms only about two per cent of our
bodyweight, but it controls our feelings,
movement, skills and every function necessary
to live. The human brain is divided into three
major parts; the cerebrum, the cerebellum,
and the brainstem. The cerebrum gives us
intelligence. It makes up 85 per cent of the
brain and operates voluntary muscles that we
have control over. The cerebrum is the area
of the brain that allows us to dance, jump
or solve puzzles. It also stores information,
which we call memory. The cerebellum or
‘little brain’ is below the cerebrum and is
just one-eighth of the size of it. The
cerebellum controls balance and tells the
muscles how to move. The brainstem
connects the rest of the brain to the spinal
cord, which runs down the neck and back.
The brainstem controls involuntary muscles
that work without us thinking about it, like
the heart, the lungs and the stomach.
