A study, “The Corpus Callosum of Albert Einstein’s Brain: Another Clue to His High Intelligence,” published in September 2013, suggests that the two hemispheres of Einstein’s brain were unusually well connected.
Einstein’s corpus callosum was thicker in many areas, which indicates greater connectivity between his brain’s two hemispheres and has been linked with higher levels of intelligence.
His left and right brain hemispheres were unusually well connected to each other and contributed to his brilliance, according to the study, conducted in part by Florida State University evolutionary anthropologist Dean Falk. The study’s 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 fibers that connects the two cerebral hemispheres and facilitates interhemispheric communication.
In 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.
The research team’s findings show that Einstein had more extensive connections between certain parts of his cerebral hemispheres compared to both younger and older control groups.
