When you look at a human brain, you mostly see a large, highly convoluted outer surface. What is this part?
Cerebrum
The part mentioned is known as the cerebrum. It is the largest part of the brain and the uppermost part of the nervous system. It has a highly convoluted surface which increases the surface area of the brain, allowing billions of neurons within a small space. It is the main centre of thought, intelligence, memory and imagination. It controls all voluntary movements with the help of cerebellum.
