For one, the relative volume of the hypothalamus nuclei maps to the gender people identify with, not their chromosomal sex [0], regardless of hormone therapy.

For one, the relative volume of the hypothalamus nuclei maps to the gender people identify with, not their chromosomal sex [0], regardless of hormone therapy. I'm pretty sure the cortical and white matter tract differences also map to different cognitive abilities (regardless of sex/gender, but some of them are more represented in a given sex/gender). As far as the brain is concerned, structure is function. Also various CPUs may be able to execute the same code, yet their architecture differences will impact their relative performance in both speed and energy efficiency. -- 0. https://academic.oup.com/brain/article/131/12/3132/295849 https://academic.oup.com/brain/article/131/12/3132/295849
