The corpus callosum is the main pathway that connects the two hemispheres of the brain and allows for communication and coordination between them. When the corpus callosum is cut, as in the case of split-brain patients, each hemisphere is unable to communicate with the other. This can lead to interesting phenomena such as the ability to simultaneously copy different figures with each hand because each hand is controlled by a different hemisphere. This is known as the "dual-task phenomenon". The other brain regions listed (angular gyrus, reticular formation, and motor cortex) are not primarily involved in interhemispheric communication and are not likely to be responsible for this phenomenon.
