The outer layer of the main part of the brain (the cerebrum). It is made of folded grey matter and gives the cerebrum its ‘wrinkly’ appearance. It is divided into four lobes – frontal, parietal, temporal and occipital. It controls conscious and voluntary processes, such as movement, the five senses and higher mental functions e.g. speech, thought, reason, emotion and memory.
