The popular belief is that women are more sensitive than men. A team of American researchers wanted to lift the veil on this belief, by studying the brains of both parties. Here is what they found.
Women are more sensitive, more emotional, softer, and equipped with more empathy than men, as proven by some studies that show that among the fairer sex, the hippocampus is more developed than at Mr. Area dedicated to the memory and processing emotions, the hippocampus is located under the surface of the cortex and consists of two symmetrical parts.
This popular belief would be true if one believes past research.
Not so sure. A team of neurologists of the Rosalind Franklin University of Medicine and Science (United States) questioned these results, which it criticizes the methodology applied in too small a sample voluntarily.
This new study is actually a meta-analysis, the conclusion will be published in the journal NeuroImage is that there is no difference in size between the brain of the man and the woman .
Individuality rather than kind
Their meta-analysis has thus examined the findings of 76 studies involving more than 6,000 participants ages and social backgrounds varied, all having in common their good health. Their brain underwent MRI, that is to say, it was scanned under magnetic resonance imaging, which allows to reveal the structure.
appears he reading these MRI? No significant difference in the size of the hippocampus (the memory area and processing emotions) whether a female or male brain. The size of this area thus does not vary by sex, but between individuals. Dr. Lise Eliot, who coordinated the work, says these findings in a statement, in which it emphasizes the exploitation of scientific results: “The anatomical differences between men and women are often used to justify prejudice, such as existence of a “male brain” and a “female brain” (…) But these studies focus on a limited number of volunteers. With our meta-analysis, we found that these differences are minimal truth or insignificant. ”
This myth of women more sensitive, more expressive, more in emotion and has a better verbal memory is wiped. As is the prejudice of a difference in brain anatomy in men and women, puisqu’apparaît also where the size of the corpus callosum connecting the two hemispheres is identical between the two sexes.
You can always continue to believe that the man may have come from Mars and women from Venus, but to look at their brain, it’s not so sure.
