There is no such thing as a "male brain" or a "female brain," new research finds.
Instead, men and women's brains are an unpredictable mishmash of malelike and femalelike features, the study concludes. Even in brain regions previously thought to show differences based on sex, variability is more common than consistency.
"Our study demonstrates that although there are sex/gender differences in brain structure, brains do not fall into two classes, one typical of males and the other typical of females, nor are they aligned along a 'male brain — female brain' continuum," the study researchers wrote Nov. 30 in the journal Proceedings of the National Academy of Sciences.
