Indeed, all of our brains seem to share a patchwork of forms; some that are more common in males, others that are more common in females, and some that are common to both. The findings could change how scientists study the brain and even how society defines gender. Some modest disparities have been reported: On average, for example, men tend to have a larger amygdala, a region associated with emotion.

Search Share The largest study to look at sex differences in brain anatomy found that women tend to have thicker cortices, whereas men had higher brain volume. The question has been as difficult to answer as it has been controversial.

Now, the largest brain-imaging study of its kind indeed finds some sex-specific patterns, but overall more similarities than differences. The work raises new questions about how brain differences between the sexes may influence intelligence and behavior.

Most studies have looked at relatively small sample sizes—typically fewer than brains—making large-scale conclusions impossible.

In the new study, a team of researchers led by psychologist Stuart Ritchie, a postdoctoral fellow at the University of Edinburgh, turned to data from UK Biobankan ongoing, long-term biomedical study of people living in the United Kingdom withenrollees.

A subset of those enrolled in the study underwent brain scans using MRI. Adjusting for age, on average, they found that women tended to have significantly thicker cortices than men.

Thicker cortices have been associated with higher scores on a variety of cognitive and general intelligence tests. When the researchers adjusted the numbers to look at the subcortical regions relative to overall brain size, the comparisons became much closer: There were only 14 regions where men had higher brain volume and 10 regions where women did.

It fits with a lot of other evidence that seems to point toward males being more variable physically and mentally. In other words, just by looking at the brain scan, or height, of someone plucked at random from the study, researchers would be hard pressed to say whether it came from a man or woman.

But since previous research mostly used relatively small sample sizes, this study confirms these predictions.

Many of the women in the study were in the age range of the stages of menopause, and hormonal fluctuations have been shown to influence brain structures. That may have played some role in the sex differences noted in the study, she says.

The controversial—and still unsettled—question is whether these patterns mean anything to intelligence or behavior. Though popular culture is replete with supposed examples of intellectual and behavioral differences between the sexes, only a few, like higher physical aggression in men, have been borne out by scientific research.

Sex differences in the brain are sexy. As MRI scanning grows ever more sophisticated, neuroscientists keep refining their search for male-female brain differences that will answer the age-old question, “Why can’t a woman think like a man?” (and vice-versa).

In a study, Steven Spencer and colleagues explored gender differences among men and women who had a strong math background. They found that merely telling women that a math test had previously shown gender differences hurt their performance.
