Question

Quizplus · Accepted Answer

In split-brain patients, the left visual field is processed by the right hemisphere of the brain, which is typically not dominant for language. However, when an image is flashed in the right visual field, it is processed by the left hemisphere, which is dominant for language. Therefore, the patient should be able to name the object if it is flashed in their right visual field.
