Fig. 8.

Scalp maps for both groups showing the numbers of connections (electrode pairs) associated with each electrode with significantly higher values of S while listening to music and to text as compared with the values of S at rest with eyes closed. Here also, the scalp maps of the two different attributes (divergence and convergence) of individual electrode regions are shown. For both groups, listening to music produced higher synchronization than listening to text. However, the degree of asymmetries of several cortical regions, especially in frontal and occipital regions while listening to music, is higher for non-musicians than musicians.
