In 1924 Lenin suffered a stroke and the Brain Institute was founded to uncover the mystery of ‘genius’. Ofcourse the verdict came back that he was a *super brain*, making sure his icon status was suitably left intact.

After Einstein died in 1955, his brain was also dissected carefully to uncover the mystery of what makes a 'genius'.
It appears his brain was 15% wider than other brains allowing better connections between neurons important for math and spatial reasoning.
Uniquely, Einstein's brain also lacked a groove, where most 'normal' brains had one. The researchers suggested that its absence may have allowed the neurons to communicate much more easily.
The parietal lobes, located behind the brain’s frontal lobes, have been linked with various kinds of higher-level thinking, including processing of visual information, mathematics, language and music. A missing groove might have allowed Einstein’s brain to form more connections between neurons in this region.

But whatever the weight, size or shape, the most important question may be why we perform these analyses at all, and what we really hope to find.

Just as Einstein captured the essence of energy, so we seek to capture the essence of genius. Our pursuit perhaps reveals more about ourselves than about the nature of genius.
We seem to want reassurance of the vastness of human potential. But who can say where genius lies or if it can be located and measured at all.
Perhaps we must accept the reality, just as we have had to accept a cosmic speed limit, that genius cannot be measured, that the processes by which some human brains create revolutionary insights reflect the intermingling of culture, history, and life experience and not simply the amount of gray matter. The insights into genius will likely not be found in finer slicing, but rather, like Einstein's theories, in some more unifying model.
