I saw it on scienceblogs.com and on David Sukuzi's website.
Also, all your words come from Broca's and Wernecke's (whether you're singing or talking) - that's from Oliver Sacks book "The Man Who Mistook His Wife for a Hat" - but I don't recall which chapter (where he details, as well, the area of the brain where melodies are apparently organized - in a chapter, IIRC, about a woman with a severe chronic form of earworm). Also, David Pinkard's books on brain and language talk about the different known functional areas of the brain (I think he may be the one who summarizes aspects of rhythm recognition).
There are couple of bloggers on
www.scienceblogs.com who are musicians and like to post about all this, although I haven't been over there for awhile.
Here's a basic link I could find on the one larger project using
Invalid Link Removed I'll bet the two researchers mentioned would answer your emails if you were interested in more about their studies.
And here's a
Invalid Link Removed that shows that we musicians are
special. I knew that.
This doesn't mean that people are born musicians, necessarily (doesn't rule it out, either) but it's clear, especially from some of the studies that people's brains respond to music, and musician's brains develop special responses and capacities.
Indeed, one of the very first fMRI studies of music was about learning to tap one's fingers rhythmically, and which part of the brain eventually became hardwired to do it (and how long that took in various people).
