The three major regions that are distinguished in human brain are:
(i) The cerebral cortex: It covers the top half of the brain so it is called cerebral hemisphere.
Functions: This area is very important as it leads to consciousness, storage and memory of information.
(ii) The cerebellum: It lies at the bottom part of brain.
Functions: It controls and coordinates accurate movements.
