The Corpus Callosum is a piece of connective tissue, about four inches long, that connects the two hemispheres of our brain. In effect, it enables them to "talk' to each other. It ensures the different functionalities work well together to give us a balanced view.
Whilst the strict demarcation of "left brain logical" and "right brain creative" has long since been discredited, we think that the functions of the two hemispheres do still broadly fall into these different functionalities.
Interesting things happen when the corpus callosum is damaged, and the "cross talk' is impaired. We can describe the things we see in our right visual field (left brain hemisphere), but without the connection to the right hemisphere we will force a logic to them. Show a picture of a chicken, and another of a shovel in the snow, and we are likely to say the shovel is to clean out the chicken shed.
