In answering this question, I need to refer to both the left and right hemispheres, as well as the limbic system. The two hemispheres are frequently referred to as left brain/right brain. The left brain/right brain concept of brain specialization was thoroughly researched and documented by the surgeon Joseph Bogen; Robert Ornstein, author of The Psychology of Consciousness; and Roger Sperry, the psychobiologist who conducted landmark “split brain” experiments, that earned him the Nobel Prize in medicine in 1981.
