From the vault: The physical differences between men and women are pretty simple to decipher from an anatomy book, but those categorical dividing lines disappear when it comes to the brain.
The physical differences between men and women are pretty simple to decipher from an anatomy book, but those categorical dividing lines disappear when it comes to the brain.whether the brain structures of men and women, like our reproductive organs, fell into separate and distinct categories based on sex. Gender-based differences in the brain, the thinking goes, could explain variations in behavior between men and women.
But after conducting a study of 1,400 men and women using four different datasets, researchers in the current study concluded that instead of having either one kind of brain or another, most people’s brains fall somewhere in the middle in terms of possessing male and female characteristics. According to the team, our brains are “mosaics” of features, some of which are more common in men, and others more common in women.
The volumes of brain regions in 42 adults. The coloration highlights the substantial overlap between male and female brains. Researchers used magnetic resonance imaging to search for differences in volume and the level of connectivity between regions of grey matter in the brains of 112 men and 169 women between the ages 18 to 79. When researchers looked at the 10 most dimorphic regions of the brain they had identified, they found that there was substantial variation between subjects no matter their gender, and that only 6 percent of the brains they analyzed were either “all-male” or “all-female.
