Abstract
Using magnetoencephalography (MEG), we compared the processing of
sinusoidal tones in the auditory cortex of 12 non-musicians, 12 professional
musicians and 13 amateur musicians. We found neurophysiological and
anatomical differences between groups. In professional musicians
as compared to non-musicians, the activity evoked in primary auditory
cortex 19-30 ms after stimulus onset was 102\% larger, and the gray
matter volume of the anteromedial portion of Heschl's gyrus was 130\%
larger. Both quantities were highly correlated with musical aptitude,
as measured by psychometric evaluation. These results indicate that
both the morphology and neurophysiology of Heschl's gyrus have an
essential impact on musical aptitude.
