Hemispheric Disturbances: On Michael Gazzaniga ... Now take the famous experiment purporting to show that voluntary choice is no such thing. “Michael Gazzaniga is one of the country's preeminent brain scientists and a keen observer of much about human behavior. 76 M.S. In 1964 he received a Ph.D from the California Institute of Technology, where he worked under the guidance of Roger Sperry, with primary responsibility for initiating human split-brain research. Mauboussin referenced the work of Michael Gazzaniga, a psychology professor who wrote the book Tales From Both Sides of the Brain: A Life in Neuroscience. Gazzaniga Then, in 1960, Dr. Joseph Bogen, who at the time was a resident at White Memorial Hospital in Los Angeles, proposed, after a careful review of the Akelaitis' literature, that the brain be split for the purpose of controlling the interhemispheric spread of epilepsy. Michael Gazzaniga and Roger W. Sperry, the first to study split brains in humans, found that several patients who had undergone a complete calloscotomy suffered from split-brain syndrome. The initial investigations of hemispheric communication and asymmetry in humans were carried out by Michael Gazzaniga, working in the laboratory of Roger Sperry. The patient was shown 2 pictures: of … In the 1960s, a young neuroscientist named Michael Gazzaniga began a series of experiments with split-brain patients that would change our … Gazzaniga and LeDoux's experiment Procedure and results. George Wolford, Michael B. Miller, and Michael Gazzaniga Psychology Department, Dartmouth College, Hanover, New Hampshire 03755 In a probability guessing experiment, subjects try to guess which of two events will occur next.

Michael Gazzaniga is the Director of the SAGE Center for the Study of Mind at the University of California, Santa Barbara. Dr. Gazzaniga is most famous for his work studying split-brain patients, where many of the discoveries we’re talking about were refined and explored.

Humans tend to match the frequency of … In their canonical work, Sperry and Gazzaniga … The renowned American neuropsychologist Michael Gazzaniga, who began his career working with Roger Sperry, has developed several devices for analyzing functional differences between the two hemispheres in split-brain patients. Split-brain patients give us a natural controlled experiment to find out “what the brain is up to” — and more importantly, how it does its work. In 1978, Michael Gazzaniga and Joseph DeLoux discovered a unique phenomenon among split-brain patients who were asked to perform a simultaneous concept task.
