Some neuroscientists believe that the function of the human brain is best explained by the lateralization theory, meaning that the right and left hemispheres of the brain perform very different functions and that the two sides communicate through each other's connections.

The brain controls your ability to think, speak, feel, see, hear, remember, and do all the things your body does. It even controls your breathing. The brain is a soft mass of supporting tissue and nerves that connects to the spinal cord. Together, the brain, spinal cord, and nerves make up the central nervous system.
