Gazzaniga has led pioneering studies in learning and understanding split brained patients and how their brains work. [9] He has performed numerous studies and done large amounts of research on split brain patients to provide a higher quality understanding into the lives of those affected by this rare phenomenon.
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]
Another study by Parsons, Gabrieli, Phelps, and Gazzaniga in 1998 demonstrated that split-brain patients may commonly perceive the world differently from the rest of us. Their study suggested that communication between brain hemispheres is necessary for imaging or simulating in one's mind the movements of others.
As explained in his 1996 book, The Emotional Brain, [2] LeDoux developed an interest in the topic of emotion through his doctoral work with Michael Gazzaniga on split-brain patients in the mid-1970s. [3] Because techniques for studying the human brain were limited at the time, he turned to studies of rodents where the brain could be studied in ...
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.
As a result, some experimental psychologists began to investigate neural bases of behaviour. Wilder Penfield created maps of primary sensory and motor areas of the brain by stimulating the cortices of patients during surgery. The work of Sperry and Gazzaniga on split brain patients in the 1950s was also instrumental in the progress of the field ...
