Quizplus · Accepted Answer

In split-brain patients, the right hemisphere processes information from the left visual field and the left hemisphere processes information from the right visual field. Since the left hemisphere is responsible for language processing, a split-brain patient who sees something in their left visual field (processed by the right hemisphere) cannot name it.
