The '''central nervous system''' (CNS) in its most simple divisions consists of all [[nervous tissue]] in the spinal cord and the brain. It is the largest division of the [[nervous system]] and has primary control over all organism behavior.  

The '''central nervous system''' (CNS) in its most simple divisions consists of all [[nervous tissue]] in the [[spinal cord]] and the brain. It is the largest division of the [[nervous system]] and has primary control over all organism behavior. Much of our understanding of the central nervous system stems from the [[computational theory of mind]]. In modern [[cognitive psychology]] and [[neuroscience]] the CNS is viewed as an information processing system similar to a modern computer. It is theorized that all thought. conscious and unconsciousness, and all behavior is controlled by the same underlying hardware of [[neurons]]. The CNS is also viewed as being inherently [[modular]] with specific functions being localized to specific areas.
