Ever since his death in 1955, scientists have asked what features of Einstein’s brain contributed to his extraordinary insights into physical laws.
Research on the anatomy of Einsteins’ genius was stymied because many of the post-mortem images and slides of tissue from the subsequently dissected organ were unavailable to researchers. The story is complex and the fate of Einstein’s brain, in fact, has furnished sufficient anecdotal raw material to produce a number of popular books.
In addition to the human drama, scientists have in recent years identified a few special attributes. The size and structure of Einstein’s parietal lobes, involved with processing spatial relationships and numbers, seemed tied to his mathematical ability.
