>Neuropsychologist Elkhonon Goldberg devotes a chapter of his recent book _The

>"The next study compares the size of a cortical area known as the Heschl's gyrus in 
>professional musicians and nonmusicians... This cortical area is critical for sound 
>processing.  And guess what - the Heschl's gyrus is twice as large in musicians as in 
>nonmusicians.  Furthermore, the greater the intensity of practicing music in the last ten 
>years, the greater the size of the Heschl's gyrus.  Again, the relatinship between 
>cognitive activation and specific brain regions is apparent and striking."
