Do you have a male brain or a female brain? The answer, according to science, is no.
you didn’t expect this to be a yes-or-no question, you’re not alone.
Male brains do seem to be built differently than female brains.
An analysis of more than 100 studies found that the volume of a man’s
brain is 8% to 13% greater than the volume of a woman’s brain, on
average. Some of the most noticeable differences were in areas of the
brain that control language, memory, emotion and behavior, according to a 2014 report in the journal Neuroscience and Biobehavioral Reviews.
find out whether these structural differences translated into cognitive
differences, scientists examined detailed brain scans of more than
1,400 men and women. No matter which group of people they looked at,
what type of scan was used or which part of the brain was examined, the
researchers consistently failed to find patterns that set men and women
“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,” the team wrote in a study
published Monday in the Proceedings of the National Academy of
Sciences. “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.”
They started with a set of
MRIs that measured the volume of gray matter in the brains of 112 men
and 169 women ages 18 to 79. On these scans, they examined 116 separate
regions and zeroed in on the 10 that showed the greatest difference
between men and women. In each case, the 281 scans were divided into
three categories – one-third considered “most male,” one-third
considered “most female” and one-third in the middle.
