Yes indeed, your brain (and mine) is built like that of a straight female. In layman's terms, this means that if you sliced off the top of your skull, and the the tops of, say, George Dubya's and Oprah Winfrey's skulls, your little ole brain would resemble Miss Winfrey's and not Dubya's. This is probably a good thing. I could have said Paris Hilton and Nelson Mandela, but that wouldn't really have worked, would it?
In any case, some broad in a white coat called Ivanka Savic, who works for the Karolinska Institute (which sounds like something out of Lost) in Sweden (yes, really) has been faffing about with MRI scans, PET scans and peoples amygdala, which isn't as rude as it sounds (unfortunately). Should you wish to learn more, click the link above, because I can't really be bothered getting into it. Brain symmetry is a terrible bore.
Furthermore, I can't imagine what sort of picture I'd attach to this article, other than one of someone's brain, and that ain't gonna sell copy, so here's one of something completely unrelated.
