Found at least 9 gender expressions in the human brain

Before advanced ultrasound technologies were introduced, the sex of a baby was usually only determined at birth by looking at the baby's genitals. Today, modern technology allows doctors to determine the sex of the fetus by the 11th week of pregnancy, with an accuracy of 40-70% (the rate will increase in the following weeks). However, this process of sex determination of the fetus is basically based on observations on the genitals.

So, besides the specific characteristics of appearance, where can the gender of the human being be determined? A team of scientists has found at least nine gender manifestations that exist in the human brain, through the use of artificial intelligence to analyze a dataset of gender diversity. obtained from four main target groups: cisgender individuals (men and women - those with a gender identity that matches the gender they were assigned at birth), as well as those who underwent definite surgery. gender (both male and female to male).

'Our goal is to demonstrate that the currently popular brain imaging methods are fully capable of showing new insights into the gender differences expressed in the brain,' Dr. Daniloo Bzdok, associate professor of biomedical engineering at McGill University, who led the research team.

Scientists have used a special machine learning algorithm to analyze brain imaging data of four main gender object groups, including men, women, transgender men, and transgender people like, in conjunction with Comprehensive profile of stereotypical sexual behavior traits. The machine learning algorithm has identified at least 9 variations (mutations) related to the brains - gender of these people. Simply put, each individual in the study can match one of the nine manifestations of this brain-related variation.

'These findings will have an important impact on the movement towards improving gender equality and diversity worldwide. By raising awareness for everyone from a biological perspective, we can build a society where individuals who identify themselves as being at the border of men and women feel integrated, rather than segregated. discrimination, 'added Dr. Bzdok.

This new finding could undermine arguments about sex education based on innate differences between men and women. Even if the definition of gender is considered a social category.
