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.
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.
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 ...
[5] [6] [7] Sperry eventually received the 1981 Nobel Prize in Medicine for his contributions to split-brain research. [8] In performing the initial experiments, Gazzaniga and his colleagues observed what happened when the left and right hemispheres in the split brains of patients were unable to communicate with each other.
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.
Roger Wolcott Sperry pioneered the inception of the chemoaffinity hypothesis following his 1960s experiments on the African clawed frog. [2] He would remove the eye of a frog and reinsert it rotated upside-down—the visual nervous system would eventually repair itself, [3] and the frog would exhibit inverted vision.
Roger Sperry and colleagues performed the first published neuropolitics experiment in 1979 with split-brain patients who had their corpus-callosum severed and thus had two brain hemispheres with severely impaired communication. [2]
In the 1950s, Roger Sperry developed split-brain preparations in non-human primates that emphasized the importance of information transfer that occurred in these neocortical connections. For example, learning on simple tasks, if restricted in sensory input and motor output to one hemisphere of a split-brain animal, would not transfer to the ...
