Split-Brain and the intermanual transfer effect

In this thesis, we have explored the split-brain phenomenon and its implications for intermanual transfer of information. Split-brain occurs when the corpus callosum, the structure that connects the two hemispheres of the brain, is surgically severed to treat certain medical conditions (e.g., epilepsy). As a result, the left and right hemispheres of the brain become functionally independent, leading to a variety of cognitive and perceptual changes. One of the most interesting effects of split-brain is the intermanual transfer effect, where learning and performance on a motor task with one hand can transfer to the other hand, even though the two hemispheres no longer communicate. This effect has been extensively studied in individuals with intact brains, and less is known about its manifestation in split-brain patients. In the present thesis we have reviewed the existing literature on split-brain patients and their performance on intermanual transfer tasks. Studies of intermanual transfer groups of split-brain patients have been included and the performance of split-brain patients has been compared to that of control groups with intact brains. The findings shed light on the nature of intermanual transfer in split-brain patients and contribute to a better understanding of the functional organization of the brain.
