Again, on maps...

Some time ago, shelley at retrospectacle posted a piece about a research in PNAS showing how english cab-driver do have an enlarged hyppocampus, the portion of our brain in charge of navigation... I did pick up the news and posted on my turn, too...

Now, here's a new paper about navigational abilities (and not). This time, the researchers have looked at navigational stratehgies of male/female, either straight or homosexuals. And they've apparently found out that gay males do use the same strategies than girsl use, i.e. less reliant on compass and a map, and more on landmarks...

They conclude that gay men's brains are a patchwork of female and male charachteristics, and therefore gay-ness is gen-related. How they make the logical jump, I'm not sure, since I can't see the reason why they rule out environmental effects on the development of said navigational abilities...

it's nature vs nurture all over again...
