Consciousness is awareness of one’s thoughts, feeling, memories, sensations and environment. The corpus callosum is the connection between the two hemispheres of the brain- right and left hemisphere. Any rupture or cut down or damage to the corpus callosum lead to the condition of so-called “split-brain” where both the hemisphere works independently. For example, when we listen to the music, our brain integrates the lyrics and the melody into a cohesive song, which is otherwise, operate by two distinct hemispheres which have different specialization. But through the corpus callosum, the two hemispheres are functioning united. So, language processing is more prominent in the left hemisphere, while music processing occurs more in the right hemisphere. Therefore, split-brain patients whose corpus callosum are damaged, either due to accident or to surgery for severe epilepsy, perceive the world in a completely different way than we do. Now, the patients with split-brain perceive the world differently leading to split consciousness.
