The '''brain''' is a major subdivision in an animal's [[central nervous system]]. It is located [[anterior]] to the other major subdivision, the [[spinal cord]]. In more primitive [[Nervous system | 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.
