They revealed where the difference between the male and female brain begins

According to a new scientific study conducted in the United States, there are biological differences between men and women since pregnancy.

A study from the Mallinckrodt Radiology Institute of the University of Washington at St. Louis, led by scientist Adam Eggebrecht, PhD and colleagues, investigated functional connectivity in 118 human fetuses (70 men and 48 women).

This scientific survey, in which the fetuses were between 25.9 and 39.6 weeks of gestation, was designed to test whether there were biological differences between the brains of women and men and whether they started to appear at from the womb.

To perform the badysis, the specialists made their observations using the RMF (functional magnetic resonance). According to research published in Developmental Cognitive Neuroscience, the developing brains of female fetuses produce "long-range" connectivity networks, a detail that does not appear in men's brains.

"More specifically, female fetuses have presented changes related to functional connectivity between the subcortical and cortical regions, related to their long-term gestational age.This model of functional connectivity-gestational age in these pairs of networks ( was) almost completely non-existent in male fetuses, "the authors reported.

The study demonstrated differences between male and female fetuses in terms of functional connectivity across seven networks.

"These observations confirm that badual dimorphism in functional brain systems occurs during pregnancy," concluded the study's authors.

In addition to developing their study, they cited other studies that showed that women had greater volume in the pre-frontal brain cortex on the lateral side and in the visual cortex. As a result, these differences could be manifested in the functional connectivity demonstrated by his study.

Warning: your own brain can cause "broken heart syndrome"

Professor Gina Rippon, author of the book The Gendered Brain, objected to the study and noted that the authors drew "unfounded conclusions" by seeking gender differences.

The main current that opposes this research is one that clearly explains that differences in behavior of both bades are rooted in social influences, while others claim that differences are accepted by biology.
