Please link to the research providing evidence for your claims that "neurological sex" in humans exists and that "it can and has been measured" via "brain scans."

I am especially interested in the research showing that "neurological sex" can be observed in humans' brains during infancy and childhood, and the reports describing the exact differences in brain scans of babies taken in the neonatal period (birth to one month) compared to the scans of those same babies at six-seven months, after the mini puberty of infancy is over. I'm also really interested in seeing the reports of the scans describing in detail how boys' and girls' brains change over the course of the puberty of adolescence, and how scans of women's brains differ from before they've been pregnant and given birth to afterwards.

This research sounds very exciting! I can't believe I somehow managed to miss it.

ETA: Once I had some brain scans done because I was having some neurological issues and had a history of tumors in my right eye orbit right next to the brain. Per usual, before I left the imaging place, I got a set of films of the scans to take with me to appointments with the various specialist doctors I was consulting at the time to try to figure out what was wrong. After numerous doctors had put these brains scans on their light boards and looked them over carefully, I finally saw my regular doctor and he did the same - then immediately started shaking his head. You see, he was the first of all the learned physicians who pored over these brain scans who bothered to look at the small print on the side of the films. Immediately, he saw that they weren't scans of my brain after all - they were the scans of the brain of a man in his late 70s! Odd that none of the physicians I'd consulted had been able to tell the difference between male brain that was pushing 80 and a female one that was nearly half that age. What, I wonder, are the chances of that?
