There is no such thing as a "male brain" or a "female brain," new research finds.
Instead, men's and women's brains are an unpredictable mishmash of male-like and female-like 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 in the journal Proceedings of the National Academy of Sciences. "Rather, even when considering only the small group of brain features that show the largest sex/gender differences, each brain is a unique mosaic of features, some of which may be more common in females compared with males, others may be more common in males compared with females, and still others may be common in both females and males."
