Unfortunately, this prof is repeating, uncritically, what the researchers SAID that their data represented and their conclusions, not what the data itself was, and what reasonable conclusions were. That data says that this effect was an "activational" effect, not an "organizational" effect. That is to say, that HRT, or more specifically, the lack of male hormones, caused this area of the brain to shrink to female dimentions. They did not start out that way. The researchers made two mistakes. First, they included data points that they shouldn't have (null results as "zero" size) and they didn't bother to run a time series plot, which when I used their data, clearly showed that the longer one was on HRT, the smaller this neural feature. For the detailed analysis, read my essay on this paper: http://sillyolme.wordpress.com/2010/02/28/the-incredable-shrinking-brain/
Actually, I am a Rocket Scientist.
Also hormonally odd (my blood has 46xy chromosomes anyway) and for most of my life, I looked male, and lived as one, trying to be the best Man a Gal could be. Anyway, in May 2005 that started changing naturally for reasons still unclear, and I'm now Zoe, not Alan : happier and more relaxed not to have to pretend any more.
This blog, written by a rocket scientist, is a fascinating collection of information, both personal and scientific, regarding intersex, transsexualism and related psychosocial and psychosexual issues. ... It is erudite and heartfelt. Just read the posts about the passport issue. You won't know whether to laugh, weep or crawl into a ball and rock gently in a corner - an amazing person. - David --- The reason I so appreciate bright, perceptive people - as opposed to ideologues whose intelligence does little to illuminate - is that they manage to both instruct and learn with a certain grace. Among such rarities in the transblogosphere is Zoe, whose direct speech and clear humanity always make her worth reading, even if one doesn’t always agree with her every conclusion. - Val --- The following is a request for permission to archive your A.E.Brain blog site which we have wanted to do for several years... The Library has traditionally collected items in print, but it is also committed to preserving electronic publications of lasting cultural value.... Since (1996) we have been identifying online publications and archiving those that we consider have national significance.... We would like to include A.E.Brain blog site in the PANDORA Archive... -Australian National Library

A quick correction, this was from Robert Sapolsky at Stanford.
Thanks for posting it!
I love Professor Sapolsky Zoe. You put me onto him last time you posted something of his ...
Thanks
