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).
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 ...
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 ]
In 1978, Michael Gazzaniga and Joseph DeLoux [16] [17] discovered a unique phenomenon among split-brain patients who were asked to perform a simultaneous concept task. The patient was shown 2 pictures: of a house in the winter time and of a chicken's claw.
Reading 1: One Brain Or Two? — Gazzaniga's split-brain research illustrating the separate functions of the brain's hemispheres. Reading 2: More Experience = Bigger Brain — Mark Rosenzweig research on rats raised in highly stimulating environments compared to rats raised in plain or dull circumstances and the effects on the 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 ...

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.
