The research showed damage to the patient’s left temporal lobe, therefore speech is controlled by the left side of the brain. In 1844, Arthur Ladbroke Wigan published a book entitled “A New View of Insanity: Duality of the Mind”. In this book, he describes the two brain hemispheres as independent parts having an independent will and way of thinking. This notion became very popular and even found its way into popular culture as with Robert Louis Stevenson’s famous story “The strange case of Dr. Jekyll and Mr. Hyde” (1886), which explores the idea of a cultured left hemisphere in contrast to an emotional right hemisphere, that is primitive and easily out of control. In the 1960s, the final evidence that the "language center" in the brain was located in the left hemisphere, came from the famous studies carried out by Roger Sperry and his colleagues. There was no other cure for people who suffered from a special kind of epilepsy other than cutting off the connection, corpus callosum, between the two hemispheres. The studies demonstrated that the left and right hemispheres are specialized in different
