The Corpus Callosum is a large structure in the brain that connects the two hemispheres. Its role is to pass information from the left hemisphere to the right and vice versa. This is a vital as the two hemispheres perform different tasks and need to communicate efficiently.

Being able to efficiently pass information from one half of the brain to the other is vital. Much like a road between to busy cities. The better the road, the more information, wealth and trade will flow between the cities.

Its has been found that the Corpus Callosum was larger in professional musicians than in non-musicians. Playing instruments involves a lot of cross hemisphere processing to keep both hand’s movements in time with each other. This suggest that by regular practice beginning early in life the Corpus Callosum can be strengthen

When Einstein died they did an autopsy on his brain to see how it was different than the average persons’ brain? What they found was incredible. There was no major difference in size or structure. The only difference they noted was in the size of the corpus callosum, the muscle that transmits information between the sides (left and right) of the brain. Einstein’s was larger than the average person’s. Since it is a muscle, they figured he had exercised it more…used it more…than other’s do. The corpus callosum stops growing at about the age of 25 years. This implies that as a child and young adult Einstein exercised his brain, thus building the muscle to a size and stature that would be of use in his later years, when he constructed his special theories concerning gravity, energy, and their relationship to space-time.
