In the late 1960's Dr. Robert Ornstein and Dr. Roger Sperry of the California Institute of Technology set out to discover what would happen if the corpus callosum, a belt of nerve fibers that connect the left and right hemisphere, were disengaged. Their research into the “split brain” revealed that each hemisphere of the brain performed independently and in a separate way.

The left side of the brain processes linear, concrete factual information and is key in language and logic, while the right side of the brain processes random, creative, intuitive, multi-sensorial images.

Subsequent studies by those who have carried on their work have revealed that each hemisphere contains some of the abilities of the "other side." When an ability that is linked to one hemisphere is developed or activated, the entire brain is activated, and all areas of mental performance improve.
