In 1961, Gazzaniga graduated from Dartmouth College.In 1964, he received a Ph.D. in psychobiology from the California Institute of Technology, where he worked under the guidance of Roger Sperry (who had primary responsibilities for initiating human split-brain research).
The concept was first introduced by Michael Gazzaniga while he performed research on split-brain patients during the early 1970s with Roger Sperry at the California Institute of Technology. [5] [6] [7] Sperry eventually received the 1981 Nobel Prize in Medicine for his contributions to split-brain research. [8]
Roger Sperry continued this line of research up until his death in 1994. Michael Gazzaniga continues to research the split brain. Their findings have been rarely critiqued and disputed; however, a popular belief that some people are more "right-brained" or "left-brained" has developed.
Split-brain patients have been subjects for numerous psychological experiments that sought to discover what occurs in the brain now that the primary interhemispheric pathways have been disrupted. Notable researchers in the field include Roger Sperry , one of the first to publish ideas involving a dual consciousness, and his famous graduate ...
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.
Research by Michael Gazzaniga and Roger Wolcott Sperry in the 1960s on split-brain patients led to an even greater understanding of functional laterality. Split-brain patients are patients who have undergone corpus callosotomy (usually as a treatment for severe epilepsy), a severing of a large part of the corpus callosum. The corpus callosum ...
In the early 1960s, the team of the neurosurgeon Joseph Bogen, the neuropsychologist Roger Sperry, and the "psychobiology" graduate student Michael Gazzaniga performed psychological experiments on patients who for medical treatment had undergone "split-brain surgery" which cuts the corpus callosum and thus severs the main link between the two sides of the brain known as the cerebral hemispheres.
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.
