Hemispheres and the cerebral cortex

• The brain is divided into two symmetrical halves called the left and right hemispheres
• Some functions are dominated by one hemisphere, which is called lateralisation
• Activity on the left side of the body are controlled by the right hemisphere and vice Versa
• The outer layer of both hemispheres is called the cerebral cortex, a 3mmm layer covering the outer parts of the brain
• The human cortex is much more developed than other animals
• The cortex appears grey due to the location of cell bodies hence the term grey matter
