The brain is a major subdivision in an animal's central nervous system. It is located anterior to the other major division, the spinal cord. In more primitive nervous systems the brain can be as simple as a single or small collection of neurons called ganglia. In the vertebrates, the brain is much more developed and is divided into three separate areas, the forebrain, the midbrain, and the hindbrain. The brain is involved in higher functioning such as decision-making, speech, and processing of the senses. Investigations using new techniques such as fMRI are expanding knowledge on the relationship between the brain and behavior.
