and right hemispheres of Albert Einstein's brain were unusually well connected
to each other and may have contributed to his brilliance, according to a new
study conducted in part by Florida State University evolutionary anthropologist
study, more than any other to date, really gets at the 'inside' of Einstein's
brain," Falk said. "It provides new information that helps make sense
of what is known about the surface of Einstein's brain."
"The Corpus Callosum of Albert Einstein's Brain: Another Clue to His High
Intelligence", was published in the journal Brain. Lead author Weiwei Men
of East China Normal University's Department of Physics developed a new technique
to conduct the study, which is the first to detail Einstein's corpus callosum,
the brain's largest bundle of fibres that connects the two cerebral hemispheres
and facilitates interhemispheric communication.
technique should be of interest to other researchers who study the brain's
all-important internal connectivity," Falk said.
technique measures and colour-codes the varying thicknesses of subdivisions of
the corpus callosum along its length, where nerves cross from one side of the
brain to the other. These thicknesses indicate the number of nerves that cross
and therefore how "connected" the two sides of the brain are in
particular regions, which facilitate different functions depending on where the
fibres cross along the length. For example, movement of the hands is
represented toward the front and mental arithmetic along the back.
particular, this new technique permitted registration and comparison of
Einstein's measurements with those of two samples – one of 15 elderly men and
one of 52 men Einstein's age in 1905. During his so-called "miracle
year" at 26 years old, Einstein published four articles that contributed
substantially to the foundation of modern physics and changed the world's views
about space, time, mass and energy.
More extensive connections
team's findings show that Einstein had more extensive connections between
certain parts of his cerebral hemispheres compared to both younger and older
research of Einstein's corpus callosum was initiated by Men, who requested the
high-resolution photographs that Falk and other researchers published in 2012
of the inside surfaces of the two halves of Einstein's brain. In addition to
Men, the current research team included Falk, who served as second author; Tao
Sun of the Washington University School of Medicine; and, from East China
Normal University's Department of Physics, Weibo Chen, Jianqi Li, Dazhi Yin,
Lili Zang and Mingxia Fan.
