But Lise Eliot, a professor of neuroscience at the Chicago Medical School and the author of Pink Brain, Blue Brain, says that anyone who goes searching for innate differences between the sexes won’t find them....
That’s a bold statement, and one science is divided on. It seems to depend on what exactly is being measured. For example, a large study in the U.K. found that many regions of men’s brains were larger than women’s, and that women on average had thicker cerebral cortices. What does that mean for how the brain works? Unclear. Another study found that “averaged across many people, sex differences in brain structure do exist, but an individual brain is likely to be just that: individual, with a mix of features,” as New Scientist reported in 2015...
Eliot blames academia and the media in part for the cycle that leads to the ongoing argument over biological brain differences. Because most scholars know that any small statistical difference between men and women will make headlines, academics, desperate for funding and attention, often focus studies on gender disparities. “You go back to data, analyze it for sex, and if you find a difference, then guess what: You have another paper,” Eliot said.
Certain brain structures in trans women have been found to be similar to cisgender women's as opposed to cis men's, and trans men's have been found to be similar to cis men's, even controlling for hormone use, which can also cause trans people's brains to become closer to those of cis people of the same gender.
The wikipedia article is biased. If these differences exist then transgenderism could be diagnosed with a CT scan or MRI and trans people wouldn't have to go through so much nonsense to get surgery or other treatments.
I and many other people reject the notion that we are born gendered. Women are actively harmed by this theory. We have fought for centuries to prove we can do math and be firefighters. Brain differences are used to justify discrimination against us.
Brains cannot be identifed as male or female at this time.
Just as there is no physical evidence for a soul there is none for gender. As a mother and aunt I know that children are born with traits that have no means of being physically identified and are not explained by environment. I don't think any physical signs have been found for geniuses either but there must be some difference. The existence of some sort of sense of being male or female is not beyond the bounds of possibility. So far it has not been proven and can't be identified.
Women have a vested interest in proving that male and female brains do not differ significantly. Trans women have a vested interest in proving there is a difference.
