Split-brain surgery involves cutting the corpus callosum, which is the bundle of nerves that connects the two hemispheres of the brain. After this surgery, the left and right hemispheres cannot communicate with each other, and certain functions may be localized to one hemisphere or the other. In this case, the object presented to the left visual field would be processed by the right hemisphere, which does not have the language function necessary for naming the object. However, the person could still point to the object correctly because this task can be performed by the left hemisphere, which controls the right side of the body.
