Brain Size Does Matter
The Scientific American claims that larger brain sizes may correlate with higher IQs!
In humans, brain size correlates, albeit somewhat weakly, with intelligence, at least when researchers control for a person’s sex (male brains are bigger) and age (older brains are smaller). Many modern studies have linked a larger brain, as measured by magnetic resonance imaging, to higher intellect, with total brain volume accounting for about 16 percent of the variance in IQ. But, as Einstein’s brain illustrates, the size of some brain areas may matter for intelligence much more than that of others does.
that sounds interesting!! i want to know if the size of certain parts of the brain makes a difference in intelligence. Because i am supposed to be getting an mri at some point so i definitely want to find out….
