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.
The left-brain interpreter is a neuropsychological concept developed by the psychologist Michael S. Gazzaniga and the neuroscientist Joseph E. LeDoux. [ 1 ] [ 2 ] It refers to the construction of explanations by the left brain hemisphere in order to make sense of the world by reconciling new information with what was known before. [ 3 ]
At Caltech, Gazzaniga worked with Sperry on the effects of split-brain surgery on perception, vision and other brain functions. The surgery, which was a treatment for severe epilepsy, involved severing the corpus callosum, which carries signals between the left-brain hemisphere, the seat of speech and analytical capacity, and the right-brain ...
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.
Gazzaniga's publication career includes books for a general audience such as The Social Brain, Mind Matters, Nature's Mind, The Ethical Brain and Who's in Charge?. He is also the editor of The Cognitive Neurosciences book series published by the MIT Press, which features the work of nearly 200 scientists and is a sourcebook for the field.
The theory of bicamerality inspired early investigations of auditory hallucination by psychologist Thomas Posey [16] and clinical psychologist John Hamilton. [17] With further research in the late 1990s using new brain imaging technology, Jaynes's ideas have received renewed attention [ 18 ] [ 19 ] and recognition for contributing to a ...
Split-brain patients have been subjects for numerous psychological experiments that sought to discover what occurs in the brain after 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 student ...
