Split-brain syndrome occurs when the corpus callosum—the bridge that lets the two hemispheres share information—is disrupted. Because each hemisphere handles different functions, the left side often governs language and naming, while the right side handles more nonverbal, spatial processing. When the connection between them is cut, information can no longer cross from one side to the other. That means a stimulus or object processed by the left hemisphere can be described or named, but information about the same object in the opposite hemisphere cannot be shared to guide naming or verbal description, and an object processed by the right hemisphere may be recognized or manipulated without being able to be verbally identified or matched with a corresponding name. Hence you can see an object in the left hemisphere that cannot be named or described, and an object in the right hemisphere that cannot be matched. This phenomenon is characteristic of split-brain syndrome.
