For one hemisphere to believe in God, and for the other to be an atheist? For one hemisphere to control your hand, whilst the other watches in surprise at this alien appendage moving of its own accord? The Hemispheric Highway To understand how this can be possible, we need to understand the structure of the brain. The corpus callosum is a wide, flat bundle of 200-300 million neural fibers connecting the left and right hemispheres of the brain. This hemispheric highway allows them to communicate with one another and coordinate actions and decision-making. This information exchange is important because the two hemispheres are highly specialised and need to be able to share their findings. For example the right hemisphere is responsible for nonverbal and spatial tasks, image and facial recognition and emotion, whereas the left hemisphere excels at
