The Nature of Things
Left Brain, Right Brain (20x9)
:
The brain's two halves or hemispheres differ both in anatomical structure and in the bodily functions they control. "Left Brain, Right Brain" is a report on recent studies into the functional differences between the two halves. Studies include administering verbal and motor tests to a subject after one hemisphere has been anesthetized, tracing blood-flow activity in the two halves as different tasks are performed and testing a patient who has had the nerve connections between the two halves severed.
