Question

Quizplus · Accepted Answer

The corpus callosum connects the two hemispheres of the brain, facilitating interhemispheric communication. A complete transection would impair activities requiring coordinated action and communication between the hemispheres. Using a gaming console often requires complex, coordinated movements and split-second decisions that involve both hemispheres for tasks like strategizing and executing movements simultaneously with both hands, making it particularly challenging without an intact corpus callosum. Other listed activities primarily involve motor skills that can be managed by one hemisphere and do not require the same level of interhemispheric coordination.
