Which researchers studied split-brain patients?

• A. Michael Gazzaniga
• B. Roger Sperry & Michael Gazzaniga
• C. Franz Gall
• D. Wernicke

Answer: (B)

Split-brain research shows how the two halves of the brain can operate independently when the connection between them is severed. Roger Sperry and Michael Gazzaniga carried out the classic studies with split-brain patients, people who had the corpus callosum cut to treat severe epilepsy. Their experiments demonstrated hemispheric specialization: language and verbal report are typically localized in the left hemisphere, while the right hemisphere more often handles spatial and nonverbal tasks. Because the two hemispheres can’t easily share information after callosal surgery, each side can respond to different information presented to it, revealing how each hemisphere processes the world differently. The other names listed are known for different brain science contributions—Franz Gall for phrenology and Wernicke for language comprehension areas—neither of whom conducted the famous split-brain experiments.
