Many people have wondered about the minds of great thinkers. What must Einstein have been thinking when he sat down at his piano and came to the conclusions that gave us relativity? How does such a fantastic mind work? For neuroscientists, who view mental activity as brain activity, some of their curiosity can be satisfied by studying the brains of great thinkers and seeing how they differ from the normal brain.
Now, brain morphology does not always correlate to behavioral differences. The findings listed below may have little to no meaning at all. Brain shape can be altered by things such as daily motor skill practice or dementia. The current data suggests that brain morphology has at most a modest effect on overall intelligence. In some cases, a larger brain makes for lower functionality. This should be kept in mind when reading about these differences between the brain of these geniuses and the average joe.
So, here are four great brains from great minds, and how they differ from yours.
Albert Einstein

Einsteins’s brain was taken, without the permission of his family, by Thomas Stoltz Harvey after Einstein’s death. His brain was preserved, photographed, dissected, and even mailed to other scientists in hopes that studying it might uncover the source of his genius. Over decades, several interesting features of his brain have been discovered, including more extensive connections between the two hemispheres of his brain, a lighter than average weight, and an enlarged lateral sulcus.
The part of his brain dedicated to mathematical and spatial thought, the inferior parietal lobe, was larger than average as well. If you would like to view his brain, it can be seen in the permanent exhibitions of the Mütter Museum in Philadelphia, Pennsylvania.
Rene Descartes

Rene Descartes was a French philosopher, famous for the declaration “I think, therefore, I am.” He is of such stature in philosophy that his work is considered the dawning of the modern era. In mathematics, for those who have suppressed memories of high school geometry, Descartes invented the Cartesian plane, allowing algebraic ideas to be expressed geometrically.
Descartes' brain has long been dust in the wind, considering that he died in 1650. Scientists have, however, recently studied the shape of his skull looking for clues as to how his brain might have differed from the norm. Using a CT scan, scientists learned that his skull is rather normal, suggesting that his brain was as well—with the single exception of a bulge in the frontal lobe area, which may correlate to the part of the brain responsible for applying words to abstract notions.
Carl Friedrich Gauss

A German mathematician of tremendous achievement, Gauss’ brain was studied after his death by noted neuroscientist Rudolf Wagner. His brain was determined to be heavier than average, and to have very notable convolutions throughout, which were hailed as the source of his intelligence. His brain was accidentally switched with that of physician Conrad Heinrich Fuchs, who died the same year, and was mislabeled for the better part of 150 years. The error was only discovered when MRI studies of both brains found they differed significantly from drawings of the brains made by Rudolf Wagner.
Vladimir Lenin

Lenin, famous for leading the 1917 Russian revolution, had his brain removed shortly after his death at the behest of Joseph Stalin, with the understanding that it would be examined to prove Lenin was a genius. His brain was kept for a few years by the communist party and was later studied by Dr. Oskar Vogt, a German neuroscientist, at the request of the Politburo.
To nobody’s surprise, it was found after comparing Lenin’s brain to that of “average people” and a few men of letters that he was an undisputed genius with a brain to match, having “giant” pyramidal cells behind his revolutionary rhetoric. It was even noted how well organized and undamaged his brain was, despite the fact that he suffered four strokes.
There you have it, some geniuses have brains which seem to support their great works, others seem to have rather banal brains. Neuroscience is still trying to understand how brain shape affects intelligence and how substantial those relationships might be. So always remember that “genius is one percent inspiration and ninety-nine percent perspiration”. Of course, the man who said that might not have had giant pyramidal cells.
