Question

Quizplus · Accepted Answer

The corpus callosum connects the two hemispheres of the brain, allowing them to communicate. If it is severed, information processed in one hemisphere (e.g., visual information from the left visual field processed in the right hemisphere) cannot be easily transferred to the other hemisphere (e.g., the left hemisphere, which predominantly handles language in most people). Thus, a person with a severed corpus callosum might not be able to verbally describe objects seen in the left visual field because the information cannot reach the language centers located in the left hemisphere.
