Where do you guys find stuff like that!!?!

Ah, there are various reliable scientific sources (see bellow for one of many).

However, I came upon the most brilliant work of this kind by word of mouth some twenty years ago, before Internet (a late friend of mine, professor of history of medicine in Paris, sent it to me). The work is Experimental Demonstration of the tomatotopic organization in the soprano (Cantatrix sopranica L.) by a brilliant French guy (deceased, regrettably) Georges Perec. Pay special attention to references (some Franch helps for some of them).

A good place to start searching for more works almost but not quite like 'Tomatotopism' is here.

Enjoy!
