As explained in his 1996 book, The Emotional Brain, [2] LeDoux developed an interest in the topic of emotion through his doctoral work with Michael Gazzaniga on split-brain patients in the mid-1970s. [3] Because techniques for studying the human brain were limited at the time, he turned to studies of rodents where the brain could be studied in ...
Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain.
Roger Wolcott Sperry (August 20, 1913 – April 17, 1994) was an American neuropsychologist, neurobiologist, cognitive neuroscientist, and Nobel laureate who, together with David Hunter Hubel [1] and Torsten Nils Wiesel, won the 1981 Nobel Prize in Physiology and Medicine for his work with split-brain research.
The two cerebral hemispheres. Of Two Minds: The Revolutionary Science of Dual-Brain Psychology is a book written by the American psychiatrist Fredric Schiffer (MD degree in 1971) [1] wherein he proposes that each person behaves as if there are two minds within the person, and that by recognizing and relating to the two separate minds, the therapist can promote healing and understanding of ...
An interesting finding among split-brain patients is many of them feel normal after the surgery and do not feel that their brains are "split". [8] The corpus callosotomy and commissurotomy have been successful in reducing, and in some cases, eliminating epileptic seizures. Van Wagenen's theory seems thus to be correct. [citation needed]
Joseph E. Bogen (July 13, 1926 – April 22, 2005) was an American neurophysiologist who specialized in split brain research and focused on theories of consciousness. He was a clinical professor of neurosurgery at the University of Southern California, Adjunct Professor of Psychology at UCLA, and a visiting professor at Caltech.
Sperry studied patients who had undergone corpus callosotomy and detailed their resulting split-brain characteristics. [2] Improvements to surgical techniques, along with refinements of the indications, have allowed van Wagenen's procedure to endure; corpus callosotomy is still commonly performed throughout the world.

The neurological model in The Origin of Consciousness in the Breakdown of the Bicameral Mind is a radical neuroscientific hypothesis that was based on research novel at the time, mainly on Michael Gazzaniga's split-brain experiments [9] [10] and left-brain interpreter theory.
