Question

Quizplus · Accepted Answer

The right hemisphere of the brain processes information from the left visual field, and the left hemisphere processes information from the right visual field. In split-brain patients, the two hemispheres cannot communicate due to the severing of the corpus callosum. Since language centers are typically located in the left hemisphere, and the word "box" appeared in the right visual field (processed by the left hemisphere), the patient will be able to verbally identify "box" but not "lock," which was processed by the right hemisphere.
