Imagine that a picture of a blue circle is briefly flashed in the left visual field of an individual with a severed corpus callosum.

When a split-brain patient is presented with two different visual stimuli, each hemisphere processes only the information from the contralateral visual field. In this case, the blue circle is processed only by the non-dominant right hemisphere, while the red square is processed only by the dominant left hemisphere. As language processing is primarily controlled by the left hemisphere, the patient will only be able to verbalize what the left hemisphere has processed.
