Well it wouldn’t let me reblog the post with this info but I think this important. This post is because of the argument between equestrianrepublican and termanal-velocity
ER seems to have a misunderstanding of what being trans is and entails. I’m going to help! We’re going to start with sexual dimorphism! It’s super important to understand this first!
Sex and the brain
Women have a larger frontal lobe (the part of the brain responsible for problem-solving and decision-making, and the limbic cortex, responsible for regulating emotions) and more white matter than men. Men have more gray matter. Men also have a larger parietal cortex and amygdala which are responsible for space perception (parietal) and sexual and social behavior (amygdala). Women also have 12% more neurons than men do because (while men’s brains are bigger) the neurons in the female brain are packed tighter which allows for quicker connections to be made
Studies on sexual dimorphism of the brain and it’s part in gender identity disorder (it is important to note GID is classified as a both a medical and psychological disorder)
study one: Zhou et al in ‘95
In this study the stri terminalis (bst) of trans individuals was studied. the BSTc is a sexually dimorphic part of the BST. It’s about two times as big in men than in women, even the neuron count is different. While it was found that hormone therapy does not affect this, it was also found that this doesnt appear until adulthood, meaning this isnt a cause of GID but a result
The trans women in this study had not begun hormone therapy and while they had the grey matter of most males this study conluded they seemed to have more grey matter in the right putamen than men
compared to control females transmen “showed higher FA values in posterior part of the right SLF, the forceps minor and corticospinal tract. Compared to control males, trans-men showed only lower FA values in the corticospinal tract.” This study found that there is an inherent difference in the brains of ftm individuals
This study found that activation in mtf individuals was similar to that of control women and DIFFERENT FROM MEN EVEN THOUGH MTF ARE MEN BIOLOGICALLY. Conclusion of study: MtF individuals had the pheremone activation of WOMEN
Garcia Falgueras ‘08
This study took a dive into the INAH 3 and 4 (instertitial nucleus of the anterior hypothalamus) and found that the INAH 3 in MtF individuas has the size and neuron count of FEMALES
Now I do believe ER stated that trans people are mentally ill and that’s that. Now while it is classified in part as a psychological disorder you could easily say (based on this information) that men or women are mentally ill because of their physical brain makeup. Not that it really matters. GID is a result of being born with a brain that differs (in sexually dimorphic terms) from your genitals. This means that GID (as I see it) is the mental disorder (which can often include depression, anxiety and of course sexual and gender dysphoria) where as your brain is not the disorder. This (as I am not a doctor it’s important to note that this is just an assumption my part) means that your brain and your genitals are not the mental disorder but a medical issue, which would be why (most likely) that transgenderism is classified as a both a mental and medical disorder.
