Excerpt
The brain is the center of the human nervous system, as it is for most other animals. The nervous system transmits and processes information about the world to the brain, causing the appropriate reactions in the body. In humans, most information is routed through the central nervous system.
The central nervous system consists of the spinal cord and the brain. The brain is where information is processed and stored, and it is responsible for controlling bodily functions and thought. Neuroscience is the science that studies the central nervous system, including the brain.
In adult humans, the brain weighs approximately three pounds. The brain itself is soft tissue that is generally white or pink in color.

The hemispheres are divided into four different lobes.
