Hemisphere and condition differences in the PDC.
The hemispheric difference was observed only for the Submediant of music-majors in the IFG (See the S3 and S6 Tables for the detail of statistical results). The sPDCi was higher for the left IFG than for the right IFG, and the sPDCo was lower for the left IFG than for the right IFG (* p < 0.05 and ** p < 0.01, Bonferroni corrected). Condition difference was observed in both groups (See also the S4 and S6 Tables for the detail of statistical results). In music-majors, the sPDCi was significantly higher for the Submediant than for the other conditions. In the sPDCo, the Submediant was significantly lower than the Supertonic. In non-music-majors, the difference between the conditions was observed between the Tonic and the Supertonic. The sPDCi/sPDCo was higher/lower for the Tonic than for the Supertonic. The box represents 1st and 3rd quartiles, the line is the median value, and the whisker represents the most extreme non-outlier value. T = Tonic, SM = Submediant, ST = Supertonic, M = music-majors, NM = Non-music-majors.
