The Right and Left Brain
It is common today to identify, in some way, with one side of the brain. You may think, for example, that you are more right brain than left. When we make such statements, we are referring to the fact that the two halves of the human brain deal with information from the senses, and hence the world, in different ways. In general, the left hemisphere is responsible for our processing of language and logic and the right deals with aspects of thought like emotions and spatial relationships. The hemispheres also control our movements, though the left hemisphere controls the right side of our bodies, and vice versa.
The fact that the two hemispheres of the brain work in different ways on different tasks is a relatively new discovery. That discovery was made by a psychobiologist named Roger Sperry and it won him a Nobel Prize in 1981. Sperry uncovered the inner workings of normal brains by studying the brain function of people who had a certain kind of brain damage. In most brains, the two halves are connected by the corpus callosum, a bundle of millions of nerves, which serves as a bridge of sorts between the two hemispheres, allowing them to communicate with each other. The people Sperry studied had had their corpus callosa cut, and because of this, their left and right brains couldnt exchange information.
