An example of split-brain behavior occurs when a picture is presented exclusively to a patient's left visual field, sending the information solely to the largely nonverbal right hemisphere. Consequently, the patient is unable to verbally name the object. However, they can recreate the picture using their left hand, which is also controlled by the right hemisphere. When the more verbal left hemisphere sees the picture that the hand drew, the patient is then able to name it, demonstrating how the hemispheres communicate via external actions.
