Information is transmitted from one hemisphere of the human brain to the other, just not by the corpus callosum. Suppose someone has his or her corpus callosum cut completely (to reduce epileptic seizures). This does not alter information transmission from one hemisphere to the other because that isn't done by the corpus callosum. Then what should happen in the special experimental setup pictured above when this person is shown a picture of a cup in the left side of the screen and a spoon in the right side of the screen and is asked to pick up what they saw with their right hand? You can assume as background that (a) In everyone -- or at least in anyone put into the special testing setup -- information displayed on the left side of the screen in the special experimental setup goes into the right hemisphere of the viewer's brain and information displayed on the right side of the screen in the special experimental setup goes into the left hemisphere of the viewer's brain and https://canvas.ubc.ca/courses/132235/quizzes/708107 2/10
