Quizplus · Accepted Answer

When a picture is flashed only to the left visual field, the information is processed in the right hemisphere of the brain, which controls the left side of the body. Therefore, the split-brain patient would be able to identify the baseball by sense of touch, using the left hand, which is controlled by the right hemisphere. The patient would not be able to say the word "baseball" as the left hemisphere (which controls speech) would not have received the visual input. The patient would also not be able to use the right hand, as it is controlled by the left hemisphere, which did not receive the visual input.
