Right-Brain Unconscious Awareness
Socialization, Self-Image, Sex, and Emotion
If we were to remove the top of someone's skull and look straight down, we would discover that the human brain is divided into halves by a large fissure called the interhemispheric fissure. These halves form the right and left brains or, rather, cerebral hemispheres. In other words, half a brain (or half a cerebrum) is a hemisphere.
If we were to squeeze our fingers down into this fissure, our progress would soon be interrupted by a large rope of nerve fibers that interconnects the two brain halves. This great bundle of fibers is called the corpus callosum.
The nerve fibers that make up the corpus callosum act as a passageway by which a portion of information from one half of the brain may travel to the other. In this way, the halves of the brains are able partly to communicate.
The other way through which a very limited amount of information can be shared is via a tiny tract of nerve fibers called the anterior commissure. There is no other "psychic corridor," and any other information exchange occurs, to a limited extent, by very indirect and circuitous routes through the very ancient limbic system and brain stem.
