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.
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.
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 ...
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 ...
The study shows patients aren’t taking the medication properly, despite its skyrocketing popularity: Net sales of antiobesity drugs such as semaglutide, or Wegovy, hit $1.1 billion in the second ...
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 ...
Gabby Douglas, who was expected to make her return to competitive gymnastics on Saturday at the Winter Cup, announced her withdrawal from the event due to a positive Covid test.
