A new theory is emerging that Albert Einstein’s extraordinary intelligence was due to a highly developed corpus callosum, the “interface” between the brain’s hemisphere’s:
A new analysis technique that compared Albert Einstein’s brain to others of the period shows the left and right cerebral hemispheres of the famous scientist’s brain were unusually well connected to each other. This connectivity may have contributed to his brilliance, according to Florida State University evolutionary anthropologist Dean Falk.
Falk was part of a research team that investigated Einstein’s corpus callosum, the large bundle of fibers that connects the two cerebral hemispheres and facilitates interhemispheric communication in the brain. The findings appear, appropriately, in the journal Brain.
IMO this study leans too heavily on the “hardware” of the brain, its morphology, and too little on the “software” of the brain, the connections that develop over time. In my view in all likelihood intelligence is a consequence of a compicated interplay between hardware and software. The old “nature vs. nurture” discussion although I’d phrase it a bit differently. I suspect that extremely high intelligence will be very hard to nail down.
However, there’s no need to speculate. If Einstein’s brilliance was a consequence of the congenital structure of his brain, then genetic testing should be able to shed light on the discussion. I strongly suspect it’s a line of inquiry that will not bear fruit.
