Split-brain or callosal syndrome is a type of disconnection ... In Sperry and Gazzaniga's "The Split Brain in Man" experiment published in Scientific American in 1967 ...
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 ...
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.
Callosal syndrome, or split-brain, is an example of a disconnection syndrome from damage to the corpus callosum between the two hemispheres of the brain. Disconnection syndrome can also lead to aphasia, left-sided apraxia, and tactile aphasia, among other symptoms.
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.
They study how those with split brain act emotionally and physically in comparison to those who do not have a split brain. Through Gazzaniga’s studies a much greater understanding of the split brain phenomenon has been brought to other physiologists as well as the general population of the world. [10] [11]
Julian Jaynes hypothesized a bicameral mind theory (which relies heavily on Gazzaniga's research on split-brain patients), where the communication between Wernicke's area and its right-hemisphere analogue was the "bicameral" structure. This structure resulted in voices/images that represented mostly warning and survival instruction, originating ...
In addition, the resultant split-brain prevents some patients from following verbal commands that require the use of their non-dominant hand. [14] Disconnection syndrome is another well-known side effect of the surgery. [15] This occurs due to the brain's inability to transfer information between the hemispheres. [16]
