The new research is the first to examine sex differences in the brain as a whole. "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." 30) in the journal Proceedings of the National Academy of Sciences.

Even in brain regions previously thought to show differences based on sex, variability is more common than consistency. Instead, men and women's brains are an unpredictable mishmash of malelike and femalelike features, the study concludes. There is no such thing as a "male brain" or a "female brain," new research finds. ![]()
