ABSTRACT
The study of the human mind has stirred the imagination of mankind for centuries. Although scientists have explored it, philosophers have argued about it, Hollywood has filmed it, and advertising has exploited it, the understanding of the mind still remains our most compelling, elusive, and challenging quest. In our current semantics mind is often replaced by cognition, mental function, behavior, or mentation. For the purposes of this chapter I use the term behavior to represent the functions of the human brain and its interactions with the environment and the rest of the body. Behavior implies the possibility for objective and subjective observation and investigation that are the bases for the disciplines I discuss.
