Many men and women have long bought into the idea that there are “male” and “female” brains, believing that explains just about every difference between the sexes. A new study【C1】______ that belief, questioning whether brains really can be distinguished by gender.

In the study, Tel Aviv University researchers【C2】______ for sex differences throughout the entire human brain.

And what did they find? Not much. Rather than offer evidence for【C3】______ brains as “male” or “female,” research shows that brains fall into a wide range, with most people falling right in the middle.

Daphna Joel, who led the study, said her research found that while there are some gender-based【C4】______ , many different types of brain can’t always be distinguished by gender.

“There’s a mountain of evidence【C9】______ the importance of sex influences at all levels of brain function,“he told The Seattle Times.

If anything, he said, the study【C10】______ that gender plays a very important role in the brain—”even when we are not clear exactly how. “
