The term for a condition in which the two hemispheres are isolated by cutting the connecting fibers is called

• A. Split Brain
• B. Hemispheric disconnection
• C. Lateralization
• D. Neuroplasticity

Answer: (A)

The idea here is interhemispheric disconnection: the two halves of the brain are cut off from each other by severing the connecting fibers, most famously the corpus callosum. This procedure makes the hemispheres operate more independently, so they can’t share information as a single integrated system. That’s why the term split brain is used—it captures the sense of the brain being divided into two largely separate processing units. Other terms don’t fit as well: hemispheric disconnection is accurate but less established as the common name for the condition; lateralization describes the specialization of functions to each side, not the act of cutting the connecting fibers; neuroplasticity refers to the brain’s ability to reorganize after injury, not the isolation of the hemispheres. In split-brain scenarios, researchers have shown that each hemisphere can handle different information streams, leading to interesting demonstrations such as information shown to one side being accessible to that hemisphere’s functions but not easily verbalized if language centers are in the other hemisphere.
