The brain

The brain controls complex behaviour. It is made of billions of interconnected neurones and has different regions that carry out different functions.

The brain contains the following main areas:

There are four main areas in the brain:

Cerebral hemispheresThe cerebrum's outer layer, it is split into two hemispheres and is highly folded. These two hemispheres make up the cerebral cortex. This controls most of our senses, intelligence, personality, conscious thought and high-level functions, such as language and verbal memory.
CerebellumControls balance, co-ordination of movement and muscular activity.
Medulla oblongataControls unconscious activities such as heart rate and breathing rate.
HypothalamusRegulates temperature and water balance within the body.
