The average human brain weighs around 3.3lbs, making up just two percent of a human's body weight. The largest part of the brain is the cerebrum, which is split into two hemispheres. What is the function of the human brain? The human brain acts as the command centre for the nervous system. Made up of millions of nerve cells called neurons, these cells can gather and transmit electrochemical signals.
Through these signals, our brains can control the functions of the body, including memory, speech and movement.

For many years, theories have circulated of people being either left or right-brain inclined. Under these theories, it has often been said that those who are left-brain inclined are more logical and objective. While those who are supposedly right-brain inclined are thought to be more creative, imaginative and emotional. Left brain vs Right brain: Diagram of the lateral view of the brain, showing the functional areas Under these left brain/right brain theories, one side of the brain is thought to be more dominant than the other. In the 1960s, ground-breaking research was carried out by Roger Sperry et al, who looked into brain function with the "Split-Brain Experiments". Roger Sperry was awarded a Nobel Prize in 1981, having revealed some of the first information ever on the difference between left and right hemispheres of the human brain. The experiment showed different sections of the brain carried out different functions, known as lateralisation.

The distinctions between the two hemispheres may have led others to conclude that people can be left or right brain-inclined thinkers. However, researchers are increasingly finding issues with such theories. Research carried out in 2016 looked at the brain function of more than a thousand people, measuring strong connections on both sides of the brain.
