The brain is the root of human life. It is the control box. It is the individual's personal computer that he carries with him everywhere. It is the computer that will determine what he thinks, how he thinks, how he feels, how he moves, and how he sees his world. It is the computer that will make or break him in any situation, but often it is the most misunderstood part of the human anatomy. People see their hands, legs, arms, eyes, and feet, but what do they know about their brain? Some people claim to know quite a bit, but in reality people just rely upon their brain to do things right and really don't realize what a complicated machine they have supporting their ears. This paper will examine the geography of the brain, its basic structures and their operations.
