Washington, Nov 16: Physicist Albert Einstein’s brain had an “extraordinary” prefrontal
cortex – unlike those of most people – which may have contributed to his
remarkable genius, a new study has claimed.
According to the study led by Florida State University evolutionary
anthropologist Dean Falk, portions of Einstein’s brain have been found
to be unlike those of most people and could be related to his
extraordinary cognitive abilities.
Falk and his colleagues describe for the first time the entire cerebral
cortex of Einstein’s brain from an examination of 14 recently discovered
photographs.
The researchers compared Einstein’s brain to 85 “normal” human brains
and, in light of current functional imaging studies, interpreted its
unusual features.
“Although the overall size and asymmetrical shape of Einstein’s brain
were normal, the prefrontal, somatosensory, primary motor, parietal,
temporal and occipital cortices were extraordinary.
“These may have provided the neurological underpinnings for some of his
visuospatial and mathematical abilities, for instance,” said Falk.
The study was published in the journal Brain.
On Einstein’s death in 1955, his brain was removed and photographed from
multiple angles with the permission of his family. Furthermore, it was
sectioned into 240 blocks from which histological slides were prepared.
A great majority of the photographs, blocks and slides were lost from
public sight for more than 55 years. The 14 photographs used by the
researchers now are held by the National Museum of Health and Medicine.
The study also published the “roadmap” to Einstein’s brain prepared in
1955 by Dr Thomas Harvey to illustrate the locations within his
previously whole brain of 240 dissected blocks of tissue, which provides
a key to locating the origins within the brain of the newly emerged
histological slides.
