Question

Quizplus · Accepted Answer

The picture shown in the left visual field is processed by the right hemisphere of the brain. In most people, language processing centers are located in the left hemisphere. Therefore, a split-brain patient (where the corpus callosum connecting the two hemispheres is severed) would not be able to verbally identify the picture because the information cannot be transferred to the language centers in the left hemisphere.
