Hemispheric Specialization Module Map | |
|
Purpose To explain how research on split-brain patients has helped us understand the special abilities of the two halves of the brain. Summary The module begins with an explanation and graphic simulation of the way in which information is carried from the main sensory channels to the cerebral hemispheres. Then the responses of a split-brain patient are simulated (based on research by Sperry and Gazzaniga) to show that, for most right handers, the main language center is located in the left hemisphere, while the right hemisphere excels at spatial tasks such as assembling blocks to match a pattern. The same experiments are simulated with a normal subject to explain the functioning of the intact corpus callosum. |
