At Einstein’s autopsy in 1955, his brain was something of a disappointment: it turned out
to be a tad smaller than the average Joe’s. Indeed, later studies have suggested a minimal
link between brain size and intelligence. It seems brain quality rather than quantity is key。
在1955 年对爱因斯坦尸体的解剖中，他的大脑多少让人有些失望——它比一个成年男子大脑的平均体积还稍微小一点。其实后来的研究也指出，大脑的体积与智力的关系极微，似乎“质”比“量”更为关键。
One important factor seems to be how well our neurons can talk to each other. Martijn van
den Heuvel, a neuroscientist at Utrecht University Medical Center in the Netherlands, found that
smarter brains seem to have more efficient networks between neurons – in other words, it
takes fewer steps to relay a message between different regions of the brain. That could explain
about a third of the variation in a population’s IQ, he says。
