The eyes have it: Men do see things differently to women
The way that the visual centers of men and women’s brains works is different, finds new research published in BioMed Central’s open access journal Biology of Sex Differences. Men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors.
Their bed nucleus of the stria terminalis should be twice as large as a woman’s, and that’s what guided their gender identities. Not that I’m a biological determinist, just a strict physicalist with no belief in metaphysical choice superceding determinism, but a lot of times the brain’s development has recursive feedback loops such that smaller choices early on can alter the size of brain structures along with sex hormones and the development environment in the womb or even outside of it for a while, the earlier the more significant. All I know is that the size of the bed nucleus of the stria terminalis is pretty consistently twice the size in men as it is in women regardless of the gender assigned at birth.
Hormones are weird and wonderful things
Trans men are assigned female at birth, FYI.
Yep, my point being that a trans man (AFAB) and a cis man (AMAB) both have their bed nucleus of the stria terminalis roughly the same size, twice the size of a woman’s. A woman’s is half the size of a man’s, regardless of whether she’s trans (AMAB) or cis (AFAB). So regardless of what the gender is assigned at birth, the relative size of the bed nucleus predicts the gender that the individual feels most comfortable as.
Has this been proven.
There’s evidence, but I don’t know enough of the science to tell how conclusive it is: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7139786/#:~:text=Regarding grey matter%2C the main,the anterior hypothalamus (INAH3).
That was even more useless than this comment.
