A new study led by a Belgian neurologist found that brain activity in transgender people resembles that found in cisgender people of their gender more than their sex assigned at birth.
Julie Bakker of the University of Liege led the research, which involved MRI scans of 160 transgender people diagnosed with gender dysphoria who were children and teenagers. The scans also measures brain microstructures using a technique called diffusion tensor imaging.
Their brain scans were compared to people of comparable age who were not diagnosed with gender dysphoria. The study found that transgender boys’ brain activity resembled cisgender boys’, and transgender girls’ brains resembled cisgender girls’.
