Sex or gender differences in the brain are of high social interest because their presence is typically assumed to prove that humans belong to two distinct categories not only in terms of their genitalia, and thus justify differential treatment of males and females. Yet, beyond when we look beyond the brains of males and females, is there a really significant difference?
Well, science says, “No.”
The majority of the brains were a mosaic of male and female structures, the team reports online today in the Proceedings of the National Academy of Sciences. Depending on whether the researchers looked at gray matter, white matter, or the diffusion tensor imaging data, between 23% and 53% of brains contained a mix of regions that fell on the male-end and female-end of the spectrum. Very few of the brains—between 0% and 8%—contained all male or all female structures. “There is no one type of male brain or female brain,” [Tel Aviv University behavioral neuroscientist Daphna] Joel says.
