In split-brain patients, the two hemispheres of the brain are unable to communicate due to the severing of the corpus callosum. Information presented to the left visual field is processed by the right hemisphere, and information presented to the right visual field is processed by the left hemisphere. The left hemisphere, which is typically responsible for language in most people, would process the word "carrot" presented in the right visual field, allowing the patient to verbally identify it. However, the image of the car presented in the left visual field would be processed by the right hemisphere, which is not primarily responsible for language, making it difficult for the patient to verbally identify the car.
