Male And Female Brains Not So Different

Scientists are not able to see any differences between male and female brains. Brain scans do not help. Even asking simple qustions like "whether someone likes boxing or worries about his or her mother" do not give definite answers, according to TODAY.

Hence the "clear all-male or all female brain patterns" are miniscule.

"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," Daphne Joel of Tel Avis University and colleagues wrote.

"Brains do not fall into two classes, one typical of males and the other typical of females."

For brain alignments, the classification is clichéd, say the researchers.

The scientists' team examined the magnetic resonance imaging (MRI) brain scans of more than 1,400 people globally. Different races, such as Americans, Chinese, Germans and Australians were included.

Some regions of the brain are clear about indicating the sex differences. "But when they considered these regions together across all their brain scans, the picture just got muddy," they reported in the Proceedings of the National Academy of Sciences.

About 23 percent and 53 percent of the MRIs showed one area at least that had a "male-end" score while another region had a "female-end" score. About, 8 percent of the brain scans showed people whose brains were either "male" or "female".

"There are very few individuals who are consistently at the 'female-end' or at the 'male-end'."

"Our study demonstrates that, although there are sex/gender differences in the brain, human brains do not belong to one of two distinct categories: male brain/female brain," they wrote.

Examining another study of 157 women and 106 men at a large Midwestern University that wanted to show the sex differences in thinking, topics such as "gambling, housework, playing golf, watching porn or cosmetics", which could fit some typical pattern.

However, there was no consistency in the pattern.

"In other words, even when considering highly stereotypical gender behaviors, there are very few individuals who are consistently at the 'female-end' or at the 'male-end', but there are many individuals who have both 'female-end' and 'male-end' characteristics," they wrote.
