All about The Brain
The brain is the control centre of the body. It weighs about 1.4 kilograms in an adult and contains billions of nerve cells called neurons. It controls thinking, memory, feelings, movement and the automatic jobs you never notice, like breathing.
The brain sends messages along nerves to every part of the body, and it receives information from the senses. Different areas of the brain handle different tasks. The cerebrum is the largest part and is used for thinking and learning.

Frequently asked questions about The Brain
How does the brain learn?
Connections between neurons get stronger when you practise something. Repeating and reviewing helps those connections last.

No. The brain is active all the time, even while you sleep, when it sorts and stores memories.
Can the brain change?
Yes. The brain can form new connections throughout life. This is called neuroplasticity.
