Gender identity is part of the brain

In a blog post in November I mentioned a new study by the University of Vienna (Kranz, Hahn, Kaufmann, Küblböck, et al.) called “White Matter Microstructure in Transsexuals and Controls Investigated by Diffusion Tensor Imaging”.

I listed this study on my reference pages in sections 1.b (Brains of transsexuals show characteristics that are part-way between male and female controls) and 5.a (Hormone exposure, especially before and around birth, can influence the development and sexual differentiation of the brain, including gender identity/Human studies).

This study is now gaining some traction in the media: An Austrian article in “Der Standard” reports that neuronal correlates of the perception of identity were found in the network of the brain. The scientists in Rupert Lanzenberger’s group found significant differences in microstructure of the brain connections between males and females, with transgender people in-between both genders.

“ScienceDaily” adds in “Networks of the brain reflect the individual gender identity” that “these results suggest that the gender identity is reflected in the structure of brain networks which form under the modulating influence of sex hormones in the course of the development of the nervous system”.

Take care and have a good Sunday ✨
