Ah really? I didn't know of this one, my knowledge of sex determination is a bit limited to the chromosome cross-overs. May I ask, if you know, how does this occur?
What I've described is basically the definition of a transsexual, and such an instance happens because of changes in hormone development in the womb. It's thus possible for the brain and body to get separate hormonal signals (Or for one to get none and go "default").
The result is wiring that for all intents and purposes is different from the body.
Studies on homosexuals' brains post mortem also indicates that gays tend to have brains with slightly more femminized or masculine traits than the heterosexual equivalent. This is sort of an aside, but it does demonstrate a sort of deviation from the norm as it were.
I'm biologically male and wired like a female, for example. Were they to examine my brain, it would likely be more in line with a woman's than a man's, save possibly for size (large skull). A lot of people don't get this, because they don't really get that men and woman have brains that actually look different (in terms of activity...It's not like they're pink for girls and blue for boys), but we do have a gender identity wired into us. It's just not particularly obvious because most people are wired appropriately for their bodies.
But I mean, I doubt I could ever be a "true man" in any sense except chromosomal. The flip side is, I wouldn't really want to be, either.
