title: Paradoxical inter-hemispheric transfer after section of the cerebral commissures.
abstract: Section of the forebrain commissures blocks the normally strong transfer of information between the two cerebral hemispheres. Although memory for a visual or tactile task is restricted to one hemisphere, animals may show high level transfer of a motor habit, and they are typically able to use combinations of eye and hand which require links between the two sides of the cerebral cortex. The evidence for paradoxical transfer is reviewed, as well as experiments that show that the cerebellum is the likely route for the spared communications between the two sides of the brain.
