Infographic : Do Clever People Have Bigger Brains?

The nervous system controls and co-ordinates your body’s activities with split-second timing. It gathers information about what is happening inside and outside your body and sends it along nerves and the spinal cord to your brain. Here the information is processed, enabling you to think, feel, remember, and move. Your brain’s size doesn’t affect any of this – having a bigger brain does not make you any more clever.
