How do the hemispheres of the brain communicate? The left and right hemispheres of the brain are connected by a band of neural fibers called the corpus callosum. Latin for "tough body", the corpus callosum is composed of a wide, flat bundle of axons and is located directly below the cerebral cortex. There are specific functions of each of the two brain hemispheres that the opposite hemisphere cannot carry out. For example, the left hemisphere of the brain controls speech and language output, while the right hemisphere contains the areas of the brain that controls spatial perception.
The video below describes a man who has undergone a split brain procedure called corpus callosotomy. Due to a medical condition, surgeons severed the corpus callosum so that the left and right hemispheres operate independently. Watch this video and learn one of the most fascinating things about the human brain:
