Study Could Not Find Distinguishing Pattern to Differentiate Between Male, Female Brains

In a study published in the journal Proceedings of the National Academy of Sciences, researchers from Tel Aviv University found that brains cannot neatly fit into the binary categories of “male” or “female” because their distinguishing factors vary across a spectrum.  The authors found that only a very small number of the brains studied had features that were entirely male, female or intermediate between the two. “Brains with features that are consistently at one end of the ‘maleness-femaleness’ continuum are rare,” one of the study’s lead researchers said. “Rather, most brains are comprised of unique ‘mosaics’ of features, some more common in females compared with males, some more common in males compared with females, and some common in both females and males.” The study hopes to help get rid of assumptions about gender differences that are politically and scientifically inaccurate.
