Here research has fewer results which are more contentious. We shall now move onto the split brain research of golf handicap tracker software Dr. Roger W Sperry. Nobel prize winner R Sperry's research concentrated on what happens when parts of the corpus callosum, which connects left and right hemisphere.
The cortex is divided into two hemispheres, left and right connected by a thick layer of cells called the corpus callosum. Most other parts of the brain are also divided laterally.
One curious fact is that women tend to have a more active corpus callosum with 10 more neuron fibers. The level of connection will have a large impact on mental processes.
Below the surface is the white matter, this chiefly consists of dendrites and axons which connect neurons to each other. A simplified model of the processing of a neuron is that it receives inputs through its dendrites and depending upon the level of inputs it.

If language is mainly processed on the left of the brain, then what happens on the right hand side, and what functions do the corresponding areas on the right hand side have?
Broca's area: plays a part in grammatical processing. Wernicke's area: naming object (syntactical processing) Angualar gyri: involved in the recognition of visual symbols Supra-marginal gyri: In most (97) right-handed people language is controlled by the left hemisphere.
One particular difference in patient with damage to one side of the brain is how they copy a diagram. A patient with left brain damage will tend to copy the overall outline of a diagram but not the details and a patient with right brain.
More importantly it is the number of connections which distinguish the way a brain function to the typical functioning a computer today, the ratio of connections to processing unit is much larger in the brain than in a computer.
