From 1958 to 1959, he was a Fellow in Medical Sciences at the National Research Council. From 1959 to 1963, he was a Resident in Neurosurgery, at White Memorial Hospital. In 1966, he received his board certification and was a Diplomate, American Board of Neurological Surgery.
Split brain research Bogen was part of a research team at Caltech with
Roger Sperry and H. G. Gordon which conducted the first
split brain study. His early surgical interventions to control
epilepsy laid the foundation for the development of modern ideas about the unique identities of the right and left brains. His work played a crucial role in the development of the split-brain experiments that won Caltech's
Roger Sperry the 1981
Nobel Prize in physiology.
Theories of consciousness Bogen argued that consciousness is subjectivity, that looking for consciousness
is like looking for the wind, you can only see its effects. Bogen suggested that scientists look for a center (a nucleus) that has distributivity (i.e. widespread inward and outward connectivity) as a site that produces subjectivity as consciousness. At the time of his death, Bogen had been researching the site in the brain where consciousness is located and was preparing a book about his findings. Bogen lent his expertise in
Wernicke's area to American psychologist
Julian Jaynes (1920–97), assisting Jaynes in the development of the
bicameral mentality hypothesis in 1976. Dr. Bogen died on April 22, 2005, in
Pasadena, California, after a long illness. ==Publications==
