What is also called the central processing unit of the body?

The brain and spinal cord make up the central nervous system (CNS). It is one of the nervous system's two components. The other component is the peripheral nervous system, which consists of nerves linking the brain and spinal cord to the rest of the body. The body's processing centre is the central nervous system. The brain controls most bodily processes, including awareness, movement, thought, speech, and the five senses of sight, hearing, feeling, tasting, and smelling.
