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 26_____ that belief, questioning whether brains really can be distinguished by gender.
In the study, Tel Aviv University researchers 27_____ for sex differences throughout the entire human brain. And what did they find? Not much. Rather than offer evidence for 28_____ 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 29_____, many different types of brain can't always be distinguished by gender.
While the “average” male and “average” female brains were 30_____ different, you couldn't tell it by looking at individual brain scans. Only a small 31_____ of people had “all-male” or “all-female” characteristics.
Larry Cahill, an American neuroscientist (神经科学家), said the study is an important addition to a growing body of research questioning 32_____ beliefs about gender and brain function. But he cautioned against concluding from this study that all brains are the same, 33_____ of gender .
“There’s a mountain of evidence 34_____ the importance of sex influences at all levels of brain function, ” he told The Seattle Times.
If anything, he said, the study 35_____ that gender plays a very important role in the brain—“even when we are not clear exactly how”.
